J

Jersey Bounce: Any ball that is advanced toward the green by virtue of the ball striking a cartpath, or highway running alongside a fairway, and remains or returns in bounds.

K

Knock-down: A type of shot designed to have a very low trajectory, usually employed to combat strong winds.

L

Lag: A long putt designed to simply get the ball close to the hole. Or, in the downswing, how far the clubhead "lags" behind the hands prior to release.

Lay-up: To hit a conservative shot intentionally short of a hazard.

Lie: The ground that the ball is resting on. "Good lies" include the fairway and the green, while bunkers, pine straw, and the rough are examples of "bad lies". Also, the angle between the center of the shaft and the sole. Incorrect "lie angle" calibration will result in toe-first or heel-first contact with the ground when swinging the club.

Line: The expected path of the ball to the hole, particularly on putts. "Stepping in a player's line" on the green is considered a major golf faux pas.

Link: A course on the ocean, usually devoid of trees and therefore windy. Many courses in the United Kingdom are links.

Loft: The angle between a vertical plane (usually the plane of the club's shaft) and the clubface.
