A golf club used for rolling the ball into the hole on the green; also a person who putts.
From the verb 'putt', which is a variant of 'put' meaning to place or position, specifically adapted for golf terminology in the 18th century. The club name derives from its function of 'putting' the ball toward the hole.
The putter is golf's most personal club - while drivers and irons follow similar designs, putters come in wildly different shapes reflecting individual putting styles and superstitions. Interestingly, 'putter' as a verb meaning to work aimlessly comes from a different etymology, related to 'potter' meaning to busy oneself with trifles.
