Any unattached natural object such as:

• Stones, loose grass, leaves, branches and sticks,
• Dead animals and animal waste,
• Worms, insects and similar animals that can be removed easily, and the mounds or webs they build (such as worm casts and ant hills), and
• Clumps of compacted soil (including aeration plugs).

Such natural objects are not loose if they are:

• Attached or growing,
• Solidly embedded in the ground (that is, cannot be picked out easily), or
• Sticking to the ball.

Special cases:

• Sand and Loose Soil are not loose impediments.
• Dew, Frost and Water are not loose impediments.
• Snow and Natural Ice (other than frost) are either loose impediments or, when on the ground, temporary water, at the player's option.
• Spider Webs are loose impediments even though they are attached to another object.

Interpretation Loose Impediment/1 - Status of Fruit

Fruit that is detached from its tree or bush is a loose impediment, even if the fruit is from a bush or tree not found on the course.

For example, fruit that has been partially eaten or cut into pieces, and the skin that has been peeled from a piece of fruit are loose impediments. But, when being carried by a player, it is his or her equipment.

Interpretation Loose Impediment/2 - When Loose Impediment Becomes Obstruction

Loose impediments may be transformed into obstructions through the processes of construction or manufacturing.

For example, a log (loose impediment) that has been split and had legs attached has been changed by construction into a bench (obstruction).

Interpretation Loose Impediment/3 - Status of Saliva

Saliva may be treated as either temporary water or a loose impediment, at the option of the player.

Interpretation Loose Impediment/4 - Loose Impediments Used to Surface a Road

Gravel is a loose impediment and a player may remove loose impediments under Rule 15.1a. This right is not affected by the fact that, when a road is covered with gravel, it becomes an artificially surfaced road, making it an immovable obstruction. The same principle applies to roads or paths constructed with stone, crushed shell, wood chips or the like.

In such a situation, the player may:

• Play the ball as it lies on the obstruction and remove gravel (loose impediment) from the road (Rule 15.1a).
• Take relief without penalty from the abnormal course condition (immovable obstruction) (Rule 16.1b).

The player may also remove some gravel from the road to determine the possibility of playing the ball as it lies before choosing to take free relief.

Interpretation Loose Impediment/5 - Living Insect Is Never Sticking to a Ball

Although dead insects may be considered to be sticking to a ball, living insects are never considered to be sticking to a ball, whether they are stationary or moving. Therefore, live insects on a ball are loose impediments.

The entire area of play within the edge of any boundaries set by the Committee:

• All areas inside the boundary edge are in bounds and part of the course.
• All areas outside the boundary edge are out of bounds and not part of the course.
• The boundary edge extends both up above the ground and down below the ground.

The course is made up of the five defined areas of the course.

Anything used, worn, held or carried by the player or the player’s caddie.

Objects used for the care of the course, such as rakes, are equipment only while they are being held or carried by the player or caddie.

Interpretation Equipment/1 - Status of Items Carried by Someone Else for the Player

Items, other than clubs, that are carried by someone other than a player or his or her caddie are outside influences, even if they belong to the player. However, they are the player's equipment when in the player's or his or her caddie's possession.

For example, if a player asks a spectator to carry his or her umbrella, the umbrella is an outside influence while in the spectator's possession. However, if the spectator hands the umbrella to the player, it is now his or her equipment.

To place a ball by setting it down and letting it go, with the intent for it to be in play.

If the player sets a ball down without intending it to be in play, the ball has not been replaced and is not in play (see Rule 14.4).

Whenever a Rule requires a ball to be replaced, the Rule identifies a specific spot where the ball must be replaced.

Interpretation Replace/1 - Ball May Not Be Replaced with a Club

For a ball to be replaced in a right way, it must be set down and let go. This means the player must use his or her hand to put the ball back in play on the spot it was lifted or moved from.

For example, if a player lifts his or her ball from the putting green and sets it aside, the player must not replace the ball by rolling it to the required spot with a club. If he or she does so, the ball is not replaced in the right way and the player gets one penalty stroke under Rule 14.2b(2) (How Ball Must Be Replaced) if the mistake is not corrected before the stroke is made.

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

Interpretation Moved/1 - When Ball Resting on Object Has Moved

For the purpose of deciding whether a ball must be replaced or whether a player gets a penalty, a ball is treated as having moved only if it has moved in relation to a specific part of the larger condition or object it is resting on, unless the entire object the ball is resting on has moved in relation to the ground.

An example of when a ball has not moved includes when:

• A ball is resting in the fork of a tree branch and the tree branch moves, but the ball's spot in the branch does not change.

Examples of when a ball has moved include when:

• A ball is resting in a stationary plastic cup and the cup itself moves in relation to the ground because it is being blown by the wind.
• A ball is resting in or on a stationary motorized cart that starts to move.

Interpretation Moved/2 - Television Evidence Shows Ball at Rest Changed Position but by Amount Not Reasonably Discernible to Naked Eye

When determining whether or not a ball at rest has moved, a player must make that judgment based on all the information reasonably available to him or her at the time, so that he or she can determine whether the ball must be replaced under the Rules. When the player's ball has left its original position and come to rest in another place by an amount that was not reasonably discernible to the naked eye at the time, a player's determination that the ball has not moved is conclusive, even if that determination is later shown to be incorrect through the use of sophisticated technology.

On the other hand, if the Committee determines, based on all of the evidence it has available, that the ball changed its position by an amount that was reasonably discernible to the naked eye at the time, the ball will be determined to have moved even though no-one actually saw it move.

The area on the hole the player is playing that:

• Is specially prepared for putting, or
• The Committee has defined as the putting green (such as when a temporary green is used).

The putting green for a hole contains the hole into which the player tries to play a ball. The putting green is one of the five defined areas of the course. The putting greens for all other holes (which the player is not playing at the time) are wrong greens and part of the general area.

The edge of a putting green is defined by where it can be seen that the specially prepared area starts (such as where the grass has been distinctly cut to show the edge), unless the Committee defines the edge in a different way (such as by using a line or dots).

If a double green is used for two different holes:

• The entire prepared area containing both holes is treated as the putting green when playing each hole.

But the Committee may define an edge that divides the double green into two different putting greens, so that when a player is playing one of the holes, the part of the double green for the other hole is a wrong green.

Any unattached natural object such as:

• Stones, loose grass, leaves, branches and sticks,
• Dead animals and animal waste,
• Worms, insects and similar animals that can be removed easily, and the mounds or webs they build (such as worm casts and ant hills), and
• Clumps of compacted soil (including aeration plugs).

Such natural objects are not loose if they are:

• Attached or growing,
• Solidly embedded in the ground (that is, cannot be picked out easily), or

To show the spot where a ball is at rest by either:

• Placing a ball-marker right behind or right next to the ball, or
• Holding a club on the ground right behind or right next to the ball.

This is done to show the spot where the ball must be replaced after it is lifted.

To place a ball by setting it down and letting it go, with the intent for it to be in play.

To change the ball the player is using to play a hole by having another ball become the ball in play.

The player has substituted another ball when he or she puts that ball in play in any way (see Rule 14.4) instead of the player’s original ball, whether the original ball was:

• In play, or
• No longer in play because it had been lifted from the course or was lost or out of bounds.

A substituted ball is the player’s ball in play even if:

• It was replaced, dropped or placed in a wrong way or wrong place, or
• The player was required under the Rules to put the original ball back in play rather than to substitute another ball.

Any place on the course other than where the player is required or allowed to play his or her ball under the Rules.

Examples of playing from a wrong place are:

• Playing a ball after replacing it on the wrong spot or without replacing it when required by the Rules.
• Playing a dropped ball from outside the required relief area.
• Taking relief under a wrong Rule, so that the ball is dropped in and played from a place not allowed under the Rules.
• Playing a ball from a no play zone or when a no play zone interferes with the player’s area of intended stance or swing.

Playing a ball from outside the teeing area in starting play of a hole or in trying to correct that mistake is not playing from a wrong place (see Rule 6.1b).

Loss of hole in match play or two penalty strokes in stroke play.

An obstruction that can be moved with reasonable effort and without damaging the obstruction or the course.

If part of an immovable obstruction or integral object (such as a gate or door or part of an attached cable) meets these two standards, that part is treated as a movable obstruction.

But this does not apply if the movable part of an immovable obstruction or integral object is not meant to be moved (such as a loose stone that is part of a stone wall).

Even when an obstruction is movable, the Committee may define it to be an immovable obstruction.

Interpretation Movable Obstruction/1 - Abandoned Ball Is a Movable Obstruction

An abandoned ball is a movable obstruction.

Any obstruction that:

• Cannot be moved without unreasonable effort or without damaging the obstruction or the course, and
• Otherwise does not meet the definition of a movable obstruction.

The Committee may define any obstruction to be an immovable obstruction, even if it meets the definition of movable obstruction.

Interpretation Immovable Obstruction/1 - Turf Around Obstruction Is Not Part of Obstruction

Any turf that is leading to an immovable obstruction or covering an immovable obstruction, is not part of the obstruction.

For example, a water pipe is partly underground and partly above ground. If the pipe that is underground causes the turf to be raised, the raised turf is not part of the immovable obstruction.

Artificial objects defining or showing out of bounds, such as walls, fences, stakes and railings, from which free relief is not allowed.

This includes any base and post of a boundary fence, but does not include:

• Angled supports or guy wires that are attached to a wall or fence, or
• Any steps, bridge or similar construction used for getting over the wall or fence.

Boundary objects are treated as immovable even if they are movable or any part of them is movable (see Rule 8.1a).

Boundary objects are not obstructions or integral objects.

Interpretation Boundary Object/1 – Status of Attachments to Boundary Object

Objects that are attached to a boundary object, but are not part of that boundary object, are obstructions and a player may be allowed free relief from them.

If the Committee does not wish to provide free relief from an obstruction attached to a boundary object, it may introduce a Local Rule providing that the obstruction is an integral object, in which case it loses its status as an obstruction and free relief is not allowed.

For example, if angled supports are so close to a boundary fence that leaving the supports as obstructions would essentially give players free relief from the boundary object, the Committee may choose to define the supports to be integral objects.

Interpretation Boundary Object/2 - Status of Gate Attached to Boundary Object

A gate for getting through a boundary wall or fence is not part of the boundary object. Such a gate is an obstruction unless the Committee chooses to define it as an integral object.

Interpretation Boundary Object/3 - Movable Boundary Object or Movable Part of Boundary Object Must Not Be Moved

Boundary objects are treated as immovable, even if part of the object is designed to be movable. To ensure a consistent approach, this applies to all boundary objects.

An example of how a movable boundary object may come into play during a round includes when a boundary stake interferes with a player's stance so he or she pulls the stake out of the ground (a breach of Rule 8.1a), but part of it breaks during removal. If the player realizes the mistake before making the next stroke, he or she may restore the improved conditions by replacing enough of the broken boundary stake to restore the interference to what it was before the stake was removed.

But if the improvement cannot be eliminated (such as when a boundary object has been bent or broken in such a way that the improvement cannot be eliminated), the player cannot avoid penalty.

An artificial object defined by the Committee as part of the challenge of playing the course from which free relief is not allowed.

Integral objects are treated as immovable (see Rule 8.1a). But if part of an integral object (such as a gate or door or part of an attached cable) meets the definition of movable obstruction, that part is treated as a movable obstruction.

Artificial objects defined by the Committee as integral objects are not obstructions or boundary objects.

An obstruction that can be moved with reasonable effort and without damaging the obstruction or the course.

If part of an immovable obstruction or integral object (such as a gate or door or part of an attached cable) meets these two standards, that part is treated as a movable obstruction.

But this does not apply if the movable part of an immovable obstruction or integral object is not meant to be moved (such as a loose stone that is part of a stone wall).

Even when an obstruction is movable, the Committee may define it to be an immovable obstruction.

Interpretation Movable Obstruction/1 - Abandoned Ball Is a Movable Obstruction

An abandoned ball is a movable obstruction.

The entire area of play within the edge of any boundaries set by the Committee:

• All areas inside the boundary edge are in bounds and part of the course.
• All areas outside the boundary edge are out of bounds and not part of the course.
• The boundary edge extends both up above the ground and down below the ground.

The course is made up of the five defined areas of the course.

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

Interpretation Moved/1 - When Ball Resting on Object Has Moved

For the purpose of deciding whether a ball must be replaced or whether a player gets a penalty, a ball is treated as having moved only if it has moved in relation to a specific part of the larger condition or object it is resting on, unless the entire object the ball is resting on has moved in relation to the ground.

An example of when a ball has not moved includes when:

• A ball is resting in the fork of a tree branch and the tree branch moves, but the ball's spot in the branch does not change.

Examples of when a ball has moved include when:

• A ball is resting in a stationary plastic cup and the cup itself moves in relation to the ground because it is being blown by the wind.
• A ball is resting in or on a stationary motorized cart that starts to move.

Interpretation Moved/2 - Television Evidence Shows Ball at Rest Changed Position but by Amount Not Reasonably Discernible to Naked Eye

When determining whether or not a ball at rest has moved, a player must make that judgment based on all the information reasonably available to him or her at the time, so that he or she can determine whether the ball must be replaced under the Rules. When the player's ball has left its original position and come to rest in another place by an amount that was not reasonably discernible to the naked eye at the time, a player's determination that the ball has not moved is conclusive, even if that determination is later shown to be incorrect through the use of sophisticated technology.

On the other hand, if the Committee determines, based on all of the evidence it has available, that the ball changed its position by an amount that was reasonably discernible to the naked eye at the time, the ball will be determined to have moved even though no-one actually saw it move.

An obstruction that can be moved with reasonable effort and without damaging the obstruction or the course.

If part of an immovable obstruction or integral object (such as a gate or door or part of an attached cable) meets these two standards, that part is treated as a movable obstruction.

But this does not apply if the movable part of an immovable obstruction or integral object is not meant to be moved (such as a loose stone that is part of a stone wall).

Even when an obstruction is movable, the Committee may define it to be an immovable obstruction.

Interpretation Movable Obstruction/1 - Abandoned Ball Is a Movable Obstruction

An abandoned ball is a movable obstruction.

To place a ball by setting it down and letting it go, with the intent for it to be in play.

If the player sets a ball down without intending it to be in play, the ball has not been replaced and is not in play (see Rule 14.4).

Whenever a Rule requires a ball to be replaced, the Rule identifies a specific spot where the ball must be replaced.

Interpretation Replace/1 - Ball May Not Be Replaced with a Club

For a ball to be replaced in a right way, it must be set down and let go. This means the player must use his or her hand to put the ball back in play on the spot it was lifted or moved from.

For example, if a player lifts his or her ball from the putting green and sets it aside, the player must not replace the ball by rolling it to the required spot with a club. If he or she does so, the ball is not replaced in the right way and the player gets one penalty stroke under Rule 14.2b(2) (How Ball Must Be Replaced) if the mistake is not corrected before the stroke is made.

An obstruction that can be moved with reasonable effort and without damaging the obstruction or the course.

If part of an immovable obstruction or integral object (such as a gate or door or part of an attached cable) meets these two standards, that part is treated as a movable obstruction.

But this does not apply if the movable part of an immovable obstruction or integral object is not meant to be moved (such as a loose stone that is part of a stone wall).

Even when an obstruction is movable, the Committee may define it to be an immovable obstruction.

Interpretation Movable Obstruction/1 - Abandoned Ball Is a Movable Obstruction

An abandoned ball is a movable obstruction.

To hold the ball and let go of it so that it falls through the air, with the intent for the ball to be in play.

If the player lets go of a ball without intending it to be in play, the ball has not been dropped and is not in play (see Rule 14.4).

Each relief Rule identifies a specific relief area where the ball must be dropped and come to rest.

In taking relief, the player must let go of the ball from a location at knee height so that the ball:

• Falls straight down, without the player throwing, spinning or rolling it or using any other motion that might affect where the ball will come to rest, and
• Does not touch any part of the player’s body or equipment before it hits the ground (see Rule 14.3b).

The area where a player must drop a ball when taking relief under a Rule. Each relief Rule requires the player to use a specific relief area whose size and location are based on these three factors:

• Reference Point: The point from which the size of relief area is measured.
• Size of Relief Area Measured from Reference Point: The relief area is either one or two club-lengths from the reference point, but with certain limits:
• Limits on Location of Relief Area: The location of the relief area may be limited in one or more ways so that, for example:
• It is only in certain defined areas of the course, such as only in the general area, or not in a bunker or a penalty area,
• It is not nearer the hole than the reference point or must be outside a penalty area or a bunker from which relief is being taken, or
• It is where there is no interference (as defined in the particular Rule) from the condition from which relief is being taken.

In using club-lengths to determine the size of a relief area, the player may measure directly across a ditch, hole or similar thing, and directly across or through an object (such as a tree, fence, wall, tunnel, drain or sprinkler head), but is not allowed to measure through ground that naturally slopes up and down.

See Committee Procedures, Section 2I (Committee may choose to allow or require the player to use a dropping zone as a relief area when taking certain relief).

Clarification - Determining Whether Ball in Relief Area

When determining whether a ball has come to rest within a relief area (i.e. either one or two club-lengths from the reference point depending on the Rule being applied), the ball is in the relief area if any part of the ball is within the one or two club-length measurement. However, a ball is not in a relief area if any part of the ball is nearer the hole than the reference point or when any part of the ball has interference from the condition from which free relief is taken.
(Clarification added 12/2018)

An obstruction that can be moved with reasonable effort and without damaging the obstruction or the course.

If part of an immovable obstruction or integral object (such as a gate or door or part of an attached cable) meets these two standards, that part is treated as a movable obstruction.

But this does not apply if the movable part of an immovable obstruction or integral object is not meant to be moved (such as a loose stone that is part of a stone wall).

Even when an obstruction is movable, the Committee may define it to be an immovable obstruction.

Interpretation Movable Obstruction/1 - Abandoned Ball Is a Movable Obstruction

An abandoned ball is a movable obstruction.

The length of the longest club of the 14 (or fewer) clubs the player has during the round (as allowed by Rule 4.1b(1)), other than a putter.

For example, if the longest club (other than a putter) a player has during a round is a 43-inch (109.22 cm) driver, a club-length is 43 inches for that player for that round.

Club-lengths are used in defining the player’s teeing area on each hole and in determining the size of the player’s relief area when taking relief under a Rule.

Interpretation Club-Length/1 - Meaning of "Club-Length" When Measuring

For the purposes of measuring when determining a relief area, the length of the entire club, starting at the toe of the club and ending at the butt end of the grip is used. However, if the club has a headcover on it or has an attachment to the end of the grip, neither is allowed to be used as part of the club when using it to measure.

Interpretation Club-Length/2 - How to Measure When Longest Club Breaks

If the longest club a player has during a round breaks, that broken club continues to be used for determining the size of his or her relief areas. However, if the longest club breaks and the player is allowed to replace it with another club (Exception to Rule 4.1b(3)) and he or she does so, the broken club is no longer considered his or her longest club.

If the player starts a round with fewer than 14 clubs and decides to add another club that is longer than the clubs he or she started with, the added club is used for measuring so long as it is not a putter.

Clarification - Meaning of “Club-Length” When Playing with Partner

In partner forms of play, either partner’s longest club, except a putter, may be used for defining the teeing area or determining the size of a relief area.
(Clarification added 12/2018)

The five defined areas that make up the course:

• The general area,
• The teeing area the player must play from in starting the hole he or she is playing,
• All penalty areas,
• All bunkers, and
• The putting green of the hole the player is playing.

The finishing point on the putting green for the hole being played:

• The hole must be 4 ¼ inches (108 mm) in diameter and at least 4 inches (101.6 mm) deep.
• If a lining is used, its outer diameter must not exceed 4 ¼ inches (108 mm). The lining must be sunk at least 1 inch (25.4 mm) below the putting green surface, unless the nature of the soil requires that it be closer to the surface.

The word “hole” (when not used as a Definition in italics) is used throughout the Rules to mean the part of the course associated with a particular teeing area, putting green and hole. Play of a hole begins from the teeing area and ends when the ball is holed on the putting green (or when the Rules otherwise say the hole is completed).

An obstruction that can be moved with reasonable effort and without damaging the obstruction or the course.

If part of an immovable obstruction or integral object (such as a gate or door or part of an attached cable) meets these two standards, that part is treated as a movable obstruction.

But this does not apply if the movable part of an immovable obstruction or integral object is not meant to be moved (such as a loose stone that is part of a stone wall).

Even when an obstruction is movable, the Committee may define it to be an immovable obstruction.

Interpretation Movable Obstruction/1 - Abandoned Ball Is a Movable Obstruction

An abandoned ball is a movable obstruction.

To place a ball by setting it down and letting it go, with the intent for it to be in play.

If the player sets a ball down without intending it to be in play, the ball has not been replaced and is not in play (see Rule 14.4).

Whenever a Rule requires a ball to be replaced, the Rule identifies a specific spot where the ball must be replaced.

Interpretation Replace/1 - Ball May Not Be Replaced with a Club

For a ball to be replaced in a right way, it must be set down and let go. This means the player must use his or her hand to put the ball back in play on the spot it was lifted or moved from.

For example, if a player lifts his or her ball from the putting green and sets it aside, the player must not replace the ball by rolling it to the required spot with a club. If he or she does so, the ball is not replaced in the right way and the player gets one penalty stroke under Rule 14.2b(2) (How Ball Must Be Replaced) if the mistake is not corrected before the stroke is made.

The standard for deciding what happened to a player’s ball – for example, whether the ball came to rest in a penalty area, whether it moved or what caused it to move.

Known or virtually certain means more than just possible or probable. It means that either:

• There is conclusive evidence that the event in question happened to the player's ball, such as when the player or other witnesses saw it happen, or
• Although there is a very small degree of doubt, all reasonably available information shows that it is at least 95% likely that the event in question happened.

"All reasonably available information" includes all information the player knows and all other information he or she can get with reasonable effort and without unreasonable delay.

Interpretation Known or Virtually Certain/1 - Applying "Known or Virtually Certain" Standard When Ball Moves

When it is not "known" what caused the ball to move, all reasonably available information must be considered and the evidence must be evaluated to determine if it is "virtually certain" that the player, opponent or outside influence caused the ball to move.

Depending on the circumstances, reasonably available information may include, but is not limited to:

• The effect of any actions taken near the ball (such as movement of loose impediments, practice swings, grounding club and taking a stance),
• Time elapsed between such actions and the movement of the ball,
• The lie of the ball before it moved (such as on a fairway, perched on longer grass, on a surface imperfection or on the putting green),
• The conditions of the ground near the ball (such as the degree of slope or presence of surface irregularities, etc), and
• Wind speed and direction, rain and other weather conditions.

Interpretation Known or Virtually Certain/2 - Virtual Certainty Is Irrelevant if It Comes to Light After Three-Minute Search Expires

Determining whether there is knowledge or virtual certainty must be based on evidence known to the player at the time the three-minute search time expires.

Examples of when the player's later findings are irrelevant include when:

• A player's tee shot comes to rest in an area containing heavy rough and a large animal hole. After a three-minute search, it is determined that it is not known or virtually certain that the ball is in the animal hole. As the player returns to the teeing area, the ball is found in the animal hole.
• Even though the player has not yet put another ball in play, the player must take stroke-and-distance relief for a lost ball (Rule 18.2b - What to Do When Ball is Lost or Out of Bounds) since it was not known or virtually certain that the ball was in the animal hole, when the search time expired.
• A player cannot find his or her ball and believes it may have been picked up by a spectator (outside influence), but there is not enough evidence to be virtually certain of this. A short time after the three-minute search time expires, a spectator is found to have the player's ball.

The player must take stroke-and-distance relief for a lost ball (Rule 18.2b) since the movement by the outside influence only became known after the search time expired.

Interpretation Known or Virtually Certain/3 - Player Unaware Ball Played by Another Player

It must be known or virtually certain that a player's ball has been played by another player as a wrong ball to treat it as being moved.

For example, in stroke play, Player A and Player B hit their tee shots into the same general location. Player A finds a ball and plays it. Player B goes forward to look for his or her ball and cannot find it. After three minutes, Player B starts back to the tee to play another ball. On the way, Player B finds Player A's ball and knows then that Player A has played his or her ball in error.

Player A gets the general penalty for playing a wrong ball and must then play his or her own ball (Rule 6.3c). Player A's ball was not lost even though both players searched for more than three minutes because Player A did not start searching for his or her ball; the searching was for Player B's ball. Regarding Player B's ball, Player B's original ball was lost and he or she must put another ball in play under penalty of stroke and distance (Rule 18.2b), because it was not known or virtually certain when the three-minute search time expired that the ball had been played by another player.

An obstruction that can be moved with reasonable effort and without damaging the obstruction or the course.

An abandoned ball is a movable obstruction.

The entire area of play within the edge of any boundaries set by the Committee:

• All areas inside the boundary edge are in bounds and part of the course.
• All areas outside the boundary edge are out of bounds and not part of the course.
• The boundary edge extends both up above the ground and down below the ground.

The course is made up of the five defined areas of the course.

The procedure and penalty when a player takes relief under Rules 17, 18 or 19 by playing a ball from where the previous stroke was made (see Rule 14.6).

The term stroke and distance means that the player both:

• Gets one penalty stroke, and
• Loses the benefit of any gain of distance towards the hole from the spot where the previous stroke was made.

The course is made up of the five defined areas of the course.

The status of a player’s ball when it lies on the course and is being used in the play of a hole:

• A ball first becomes in play on a hole:
• When the player makes a stroke at it from inside the teeing area, or
• In match play, when the player makes a stroke at it from outside the teeing area and the opponent does not cancel the stroke under Rule 6.1b.
• That ball remains in play until it is holed, except that it is no longer in play:
• When it is lifted from the course,
• When it is lost (even if it is at rest on the course) or comes to rest out of bounds, or
• When another ball has been substituted for it, even if not allowed by a Rule.

A ball that is not in play is a wrong ball.

The player cannot have more than one ball in play at any time. (See Rule 6.3d for the limited cases when a player may play more than one ball at the same time on a hole.)

When the Rules refer to a ball at rest or in motion, this means a ball that is in play.

An abandoned ball is a movable obstruction.

The status of a ball that is not found in three minutes after the player or his or her caddie (or the player’s partner or partner’s caddie) begins to search for it.

If the search begins and is then temporarily interrupted for a good reason (such as when the player stops searching when play is suspended or needs to stand aside to wait for another player to play) or when the player has mistakenly identified a wrong ball:

• The time between the interruption and when the search resumes does not count, and
• The time allowed for search is three minutes in total, counting the search time both before the interruption and after the search resumes.

Interpretation Lost/1 - Ball May Not Be Declared Lost

A player may not make a ball lost by a declaration. A ball is lost only when it has not been found within three minutes after the player or his or her caddie or partner begins to search for it.

For example, a player searches for his or her ball for two minutes, declares it lost and walks back to play another ball. Before the player puts another ball in play, the original ball is found within the three-minute search time. Since the player may not declare his or her ball lost, the original ball remains in play.

Interpretation Lost/2 - Player May Not Delay the Start of Search to Gain an Advantage

The three-minute search time for a ball starts when the player or his or her caddie (or the player's partner or partner's caddie) starts to search for it. The player may not delay the start of the search in order to gain an advantage by allowing other people to search on his or her behalf.

For example, if a player is walking towards his or her ball and spectators are already looking for the ball, the player cannot deliberately delay getting to the area to keep the three-minute search time from starting. In such circumstances, the search time starts when the player would have been in a position to search had he or she not deliberately delayed getting to the area.

Interpretation Lost/3 - Search Time Continues When Player Returns to Play a Provisional Ball

If a player has started to search for his or her ball and is returning to the spot of the previous stroke to play a provisional ball, the three-minute search time continues whether or not anyone continues to search for the player's ball.

Interpretation Lost/4 - Search Time When Searching for Two Balls

When a player has played two balls (such as the ball in play and a provisional ball) and is searching for both, whether the player is allowed two separate three-minute search times depends how close the balls are to each other.

If the balls are in the same area where they can be searched for at the same time, the player is allowed only three minutes to search for both balls. However, if the balls are in different areas (such as opposite sides of the fairway) the player is allowed a three-minute search time for each ball.

The procedure and penalty when a player takes relief under Rules 17, 18 or 19 by playing a ball from where the previous stroke was made (see Rule 14.6).

The term stroke and distance means that the player both:

• Gets one penalty stroke, and
• Loses the benefit of any gain of distance towards the hole from the spot where the previous stroke was made.

To change the ball the player is using to play a hole by having another ball become the ball in play.

The player has substituted another ball when he or she puts that ball in play in any way (see Rule 14.4) instead of the player’s original ball, whether the original ball was:

• In play, or
• No longer in play because it had been lifted from the course or was lost or out of bounds.

A substituted ball is the player’s ball in play even if:

• It was replaced, dropped or placed in a wrong way or wrong place, or
• The player was required under the Rules to put the original ball back in play rather than to substitute another ball.

Any place on the course other than where the player is required or allowed to play his or her ball under the Rules.

Examples of playing from a wrong place are:

• Playing a ball after replacing it on the wrong spot or without replacing it when required by the Rules.
• Playing a dropped ball from outside the required relief area.
• Taking relief under a wrong Rule, so that the ball is dropped in and played from a place not allowed under the Rules.
• Playing a ball from a no play zone or when a no play zone interferes with the player’s area of intended stance or swing.

Playing a ball from outside the teeing area in starting play of a hole or in trying to correct that mistake is not playing from a wrong place (see Rule 6.1b).

Loss of hole in match play or two penalty strokes in stroke play.

The area on the hole the player is playing that:

• Is specially prepared for putting, or
• The Committee has defined as the putting green (such as when a temporary green is used).

The putting green for a hole contains the hole into which the player tries to play a ball. The putting green is one of the five defined areas of the course. The putting greens for all other holes (which the player is not playing at the time) are wrong greens and part of the general area.

The edge of a putting green is defined by where it can be seen that the specially prepared area starts (such as where the grass has been distinctly cut to show the edge), unless the Committee defines the edge in a different way (such as by using a line or dots).

If a double green is used for two different holes:

• The entire prepared area containing both holes is treated as the putting green when playing each hole.

But the Committee may define an edge that divides the double green into two different putting greens, so that when a player is playing one of the holes, the part of the double green for the other hole is a wrong green.

The entire area of play within the edge of any boundaries set by the Committee:

• All areas inside the boundary edge are in bounds and part of the course.
• All areas outside the boundary edge are out of bounds and not part of the course.
• The boundary edge extends both up above the ground and down below the ground.

The course is made up of the five defined areas of the course.

But the Committee may define an edge that divides the double green into two different putting greens, so that when a player is playing one of the holes, the part of the double green for the other hole is a wrong green.

The finishing point on the putting green for the hole being played:

• The hole must be 4 ¼ inches (108 mm) in diameter and at least 4 inches (101.6 mm) deep.
• If a lining is used, its outer diameter must not exceed 4 ¼ inches (108 mm). The lining must be sunk at least 1 inch (25.4 mm) below the putting green surface, unless the nature of the soil requires that it be closer to the surface.

The word “hole” (when not used as a Definition in italics) is used throughout the Rules to mean the part of the course associated with a particular teeing area, putting green and hole. Play of a hole begins from the teeing area and ends when the ball is holed on the putting green (or when the Rules otherwise say the hole is completed).

To show the spot where a ball is at rest by either:

• Placing a ball-marker right behind or right next to the ball, or
• Holding a club on the ground right behind or right next to the ball.

This is done to show the spot where the ball must be replaced after it is lifted.

This is done to show the spot where the ball must be replaced after it is lifted.

To place a ball by setting it down and letting it go, with the intent for it to be in play.

If the player sets a ball down without intending it to be in play, the ball has not been replaced and is not in play (see Rule 14.4).

Whenever a Rule requires a ball to be replaced, the Rule identifies a specific spot where the ball must be replaced.

Interpretation Replace/1 - Ball May Not Be Replaced with a Club

For a ball to be replaced in a right way, it must be set down and let go. This means the player must use his or her hand to put the ball back in play on the spot it was lifted or moved from.

For example, if a player lifts his or her ball from the putting green and sets it aside, the player must not replace the ball by rolling it to the required spot with a club. If he or she does so, the ball is not replaced in the right way and the player gets one penalty stroke under Rule 14.2b(2) (How Ball Must Be Replaced) if the mistake is not corrected before the stroke is made.

A form of play where a player or side competes against all other players or sides in the competition.

In the regular form of stroke play (see Rule 3.3):

• A player’s or side’s score for a round is the total number of strokes (including strokes made and any penalty strokes) to hole out on each hole, and
• The winner is the player or side who completes all rounds in the fewest total strokes.

Other forms of stroke play with different scoring methods are Stableford, Maximum Score and Par/Bogey (see Rule 21).

All forms of stroke play  can be played either in individual competitions (each player competing on his or her own) or in competitions involving sides of partners (Foursomes or Four-Ball).

The forward movement of the club made to strike the ball.

But a stroke has not been made if the player:

• Decides during the downswing not to strike the ball and avoids doing so by deliberately stopping the clubhead before it reaches the ball or, if unable to stop, by deliberately missing the ball.
• Accidentally strikes the ball when making a practice swing or while preparing to make a stroke.

When the Rules refer to "playing a ball," it means the same as making a stroke.

The player's score for a hole or a round is described as a number of "strokes" or "strokes taken," which means both all strokes made and any penalty strokes (see Rule 3.1c).

Interpretation Stroke/1 - Determining If a Stroke Was Made

If a player starts the downswing with a club intending to strike the ball, his or her action counts as a stroke when:

• The clubhead is deflected or stopped by an outside influence (such as the branch of a tree) whether or not the ball is struck.
• The clubhead separates from the shaft during the downswing and the player continues the downswing with the shaft alone, whether or not the ball is struck with the shaft.
• The clubhead separates from the shaft during the downswing and the player continues the downswing with the shaft alone, with the clubhead falling and striking the ball.

The player's action does not count as a stroke in each of following situations:

• During the downswing, a player's clubhead separates from the shaft. The player stops the downswing short of the ball, but the clubhead falls and strikes and moves the ball.
• During the backswing, a player's clubhead separates from the shaft. The player completes the downswing with the shaft but does not strike the ball.
• A ball is lodged in a tree branch beyond the reach of a club. If the player moves the ball by striking a lower part of the branch instead of the ball, Rule 9.4 (Ball Lifted or Moved by Player) applies.

Loss of hole in match play or two penalty strokes in stroke play.

The position of a player’s feet and body in preparing for and making a stroke.

The line where the player intends his or her ball to go after a stroke, including the area on that line that is a reasonable distance up above the ground and on either side of that line.

The line of play is not necessarily a straight line between two points (for example, it may be a curved line based on where the player intends the ball to go).

The forward movement of the club made to strike the ball.

But a stroke has not been made if the player:
