Teeing ground in the context of "Golf"

A golf course is the grounds on which the sport of golf is played. It consists of a series of holes, each consisting of a tee box, a fairway, the rough and other hazards, and a green with a cylindrical hole in the ground, known as a "cup". The cup holds a flagstick, known as a "pin". A standard round of golf consists of 18 holes, and as such most courses contain 18 distinct holes; however, there are many 9-hole courses and some that have holes with shared fairways or greens. There are also courses with a non-standard number of holes, such as 12 or 14.

The vast majority of golf courses have holes of varying length and difficulties that are assigned a standard score, known as par, that a proficient player should be able to achieve; this is usually three, four or five strokes. Par-3 courses consist of holes all of which have a par of three. Short courses have gained in popularity; these consist of mostly par 3 holes, but often have some short par 4 holes.

An iron is a type of club used in the sport of golf to propel the ball towards the hole. Irons typically have shorter shafts and smaller clubheads than woods, the head is made of solid iron or steel, and the head's primary feature is a large, flat, angled face, usually scored with grooves. Irons are used in a wide variety of situations, typically from the teeing ground on many par-3 holes, from the fairway or rough as the player approaches the green, and to extract the ball from hazards, such as bunkers or even shallow water hazards.

Irons are the most common type of club; a standard set of 14 golf clubs will usually contain between 7 and 11 irons, including wedges. Irons are customarily differentiated by a number from 1 to 10 (most commonly 3 to 9) that indicates the relative angle of loft on the clubface, although a set of irons will also vary in clubhead size, shaft length, and hence lie angle as the loft (and number) increase. Irons with higher loft than the numbered irons are called wedges, which are typically marked with a letter indicating their name, and are used for a variety of "utility" shots requiring short distances or high launch angles.

In golf, par is the predetermined number of strokes that a proficient (scratch, or zero handicap) golfer should require to complete a hole, a round (the sum of the pars of the played holes), or a tournament (the sum of the pars of each round). For scoring purposes, a golfer's number of strokes is compared with the par score to determine how much the golfer was either "over par", "under par", or "even/level par".

Holes are generally assigned par values between three and five based on the distance from the teeing ground to the putting green, and occasionally other factors such as terrain and obstacles. A typical 18-hole golf course will have a total par around 72, and a 9-hole par-3 course (where all holes are rated as par 3) will have a total par of 27.
