Golf reviewed by Josh Cassin, +3.7 handicap index

This is the vocabulary a golfer actually meets, defined without sending you to another entry to understand the first one. Fifty-two terms rather than a hundred and twenty: the ones that change what you do next, grouped so you can find them.

If you are looking for the arithmetic rather than the words, the handicap index calculator and the strokes received calculator apply the rules directly.

How to use this

Golf vocabulary has a specific failure mode: most glossaries define a term using two others you also do not know. Scrambling explained as "getting up and down after missing a green" helps nobody who does not already know what up and down means. Every definition below is written to stand alone, and where one term genuinely depends on another the dependency is spelled out rather than assumed.

Three terms are worth reading before the rest, because they are the ones most often used loosely and they change what the others mean.

Par is an assumption, not a target. It is the strokes a scratch golfer needs to reach the green, plus two putts — always two, on every hole. That is why par 3, 4 and 5 differ only in how many shots the assumption allows before the green, and why putting is where amateurs give most of it back.

A handicap is two different numbers. Your Handicap Index describes you and travels with you; your Course Handicap is what you receive today, here, from these tees. Conflating them is the single most common source of argument in society golf.

Stroke index ranks separation, not difficulty. It marks how much a hole favours a scratch golfer over a bogey one. A short par 3 over water is hard for both equally, so it separates them very little — which is why it often carries a high index despite being the hole everyone fears.

The rest is grouped by where you meet it: on the card, in your statistics, on the course, in your swing, in your bag, and in the formats people play.

Scoring

Par: The score a scratch golfer is expected to take on a hole: the strokes to reach the green plus two putts. Two putts are assumed on every hole, which is why putting is where most amateurs lose to par.
Birdie: One under par on a hole. Two under is an eagle, three under an albatross — a shot most golfers never hit.
Bogey: One over par. Eighteen bogeys is 90 on a par 72, which is why breaking 90 requires no good holes at all, only the absence of bad ones.
Stableford: A format awarding points per hole rather than counting strokes: two for a net par, three for a net birdie, nothing below a net bogey. It caps the damage of one disastrous hole, which is why it suits mixed fields.
Gross and net: Gross is the score you shot; net is that score minus the handicap strokes you receive. Competitions are usually decided on net, which is what lets a 24 handicap beat a 6.
Scratch: A golfer whose Handicap Index is zero. Better than scratch is a plus handicap, written +2, and those players give strokes back rather than receiving them.

Handicap

Handicap Index: A portable measure of ability, calculated from your best recent rounds and carried between courses. It is not the number of strokes you receive on any given day.
Course Handicap: The strokes you actually receive at one course from one set of tees, from your Index, the Slope Rating and the gap between Course Rating and par. The same Index gives a different number at every course.
Course Rating: The score a scratch golfer is expected to shoot from a set of tees, to one decimal. A rating above par means the course plays harder than its par suggests.
Slope Rating: How much harder a course plays for a bogey golfer than for a scratch one, on a scale of 55 to 155 where 113 is standard. A value outside that range is a bad record, not an extreme course.
Score Differential: One round expressed on a course of standard difficulty, so rounds from different courses can be averaged. A Handicap Index is an average of differentials, never of scores.
Stroke index: The ranking of holes from 1 to 18 on a card, deciding where handicap strokes fall. It ranks how much a hole separates a bogey golfer from a scratch one, not how hard it plays outright.
Playing Conditions Calculation: An adjustment of −1.0 to +3.0 applied to every differential from one day at one course when the field scored abnormally. Computed by your federation, so it is zero in any calculation done by hand.

Statistics

Greens in regulation: Reaching the green in par minus two — one shot on a par 3, two on a par 4. The statistic most closely tied to score at every level.
Fairways in regulation: The proportion of tee shots finishing on the fairway, counted only where you use a driver or fairway wood. Par 3s are excluded.
Scrambling: The proportion of holes where you miss the green and still make par or better. It measures whether the short game rescues an ordinary round.
Strokes gained: How many shots you gain or lose against a benchmark from the same position, rather than against par. It answers where strokes go, which a total score cannot.
Up and down: Holing out in two shots from off the green — one chip or pitch, one putt. The unit scrambling counts.
Three-putt: Taking three putts on a green. Above 20 handicap it costs more strokes across a season than any swing fault, and it is the leak golfers are least likely to name.

On the course

Tee box: The area a hole is played from. Most courses offer several sets at different lengths, and moving forward one set is the largest single improvement available to a golfer who has lost distance.
Dogleg: A hole bending left or right, so the green is not visible from the tee. The corner decides whether the driver is the right club.
Links: A course on coastal sandy ground, firm underfoot and exposed to wind, where the ball runs rather than stops. Not a synonym for golf course, though often used as one.
Rough: Longer grass either side of the fairway. Its depth changes what is possible far more than its existence does: playable rough costs accuracy, deep rough costs a stroke.
Bunker: A hazard filled with sand. You may not ground your club in one before playing, a rule that catches more amateurs than the shot itself.
Penalty area: Water and other marked ground where a ball may be dropped under penalty of one stroke. Called a hazard before 2019, and still called that by nearly everybody.
Out of bounds: Ground outside the course, marked by white stakes. It costs stroke and distance — you replay from where you were, one shot worse — which makes it the most expensive mistake in golf.
Provisional ball: A second ball played when the first may be lost or out of bounds, to avoid walking back. Announce it before playing, or the second ball becomes the ball in play.
Pin high: Level with the flag but off to one side. The distance was right and the direction was not, which is a different problem from being short.

The swing

Slice: A shot curving hard left to right for a right-hander, caused mainly by a clubface open to the swing path. The most common miss in amateur golf.
Hook: The mirror image of a slice, curving right to left for a right-hander, from a face closed to the path.
Fade and draw: The controlled versions of a slice and a hook — a gentle curve played on purpose. The difference is amplitude and intent, not mechanism.
Swing path: The direction the clubhead travels through impact, relative to the target. With face angle it decides the curve; face angle decides where the ball starts.
Angle of attack: Whether the clubhead is descending or ascending at impact. Descending with irons, ascending with a driver off a tee, and reversing the two is a common source of poor contact.
X-factor: The separation between shoulder and hip rotation at the top of the backswing. Usually flagged as insufficient below 25° and excessive above 60°.
Tempo: The ratio between time going back and coming down, close to 3:1 on tour. One of the few things a phone camera measures rather than estimates.
Casting: Releasing the wrist angle too early in the downswing, so the club loses speed before impact. Often described as throwing the club at the ball.
Early extension: Pushing the hips towards the ball during the downswing, removing the room the arms need. A frequent cause of both blocks and hooks in the same round.
Kinematic sequence: The order in which body segments accelerate through the downswing — hips, torso, arms, club. Out of order, speed is lost regardless of effort.

Equipment

Loft: The angle of a clubface, deciding how high and how far the ball goes. A modern 7 iron is stronger-lofted than one from twenty years ago, which is why comparing club numbers across eras means nothing.
Shaft flex: How much a shaft bends during the swing, matched to swing speed rather than to strength. Too stiff costs height and distance; too soft costs control.
Bounce: The angle on a wedge sole that stops it digging. High bounce suits soft sand and steep swings, low bounce suits firm ground and shallow ones.
Groove: The lines cut into a clubface, which channel water and grass away rather than creating spin by themselves. Worn grooves cost most from the rough and in the wet.
Launch monitor: A device measuring ball and club data at impact. It measures what happened to the ball, not what your body did — different instruments answering different questions.
Compression: How much a ball deforms at impact, usually quoted as a number. Lower compression suits slower swing speeds, though the effect is smaller than marketing suggests.

Formats and etiquette

Match play: Each hole is won, lost or halved rather than strokes being totalled. A disastrous hole costs one hole rather than the round, which changes strategy completely.
Stroke play: Counting every stroke over the round, lowest total winning. The default format, and the one where a single blow-up hole is most expensive.
Fourball: Two pairs, each player plays their own ball, and each side counts its better score on every hole.
Foursomes: Two pairs, each side playing one ball in alternate shots. Cruel and quick, and the format most likely to end a friendship.
Scramble: Every player hits, the team picks the best ball, and everyone plays again from there. Nobody plays a shot alone, which is why it suits fields containing beginners.
Ready golf: Playing when you are ready rather than strictly in order of who is furthest away, to keep pace. Now recommended in most casual play.
Honour: The right to play first from the tee, held by whoever won the last hole. Kept in match play and largely replaced by ready golf elsewhere.
Pitch mark: The dent a ball leaves on landing on a green. Repaired within minutes it heals in a day; left alone it takes weeks, and every putt crossing it is affected.

Frequently asked questions

What golf terms should a beginner learn first?

Par, bogey, birdie and stroke index, in that order. The first three let you read a scorecard and the fourth tells you where your handicap strokes fall, which is the one most new golfers never have explained to them. Everything about swing mechanics can wait until you have a swing to describe.

What is the difference between a Handicap Index and a Course Handicap?

The Index is portable and describes you; the Course Handicap is the strokes you actually receive at one course from one set of tees. The same Index gives a different number at every course, because it is scaled by the Slope Rating and by the gap between Course Rating and par.

Why is a par 3 sometimes ranked as an easy hole when it is hard?

Because the stroke index ranks separation, not difficulty. It marks how much a hole favours a scratch golfer over a bogey one, and a short par 3 over water is hard for both of them equally — so it separates them very little and tends to carry a high index.

Is a hazard the same thing as a penalty area?

They are the same ground under two names. The Rules of Golf renamed hazards as penalty areas in 2019 and widened what counts, but nearly everyone still says hazard on the course. If someone says hazard they mean the red or yellow stakes.
