Law 22: The Umpire's Vocabulary

2 parts · 2 tests · 20 facts · updated 29 October 2026 · markdown

Badminton officials speak in a fixed set of words. Law 22 brings together the definitions in the Laws of Badminton and the BWF standard vocabulary: what a rally, a stroke and the serving side are, and the exact announcements the umpire makes from the first serve to the last point.

The definitions are short. A rally is a sequence of one or more strokes starting with the service, until the shuttle ceases to be in play; a stroke is a movement of the player's racket with an intention to hit the shuttle; the serving side is the side having the right to serve; singles is a match with one player on each of the opposing sides. At the start, the umpire introduces the player on the right, then the left, then the server, ending with 'love all; play'. In doubles the announcement ends 'X to serve to Y; love all; play'. 'Game' is called straight after the last rally, followed by the result, and after the interval game two begins with its own number in the call. The final game opens with 'Final game; love all; play'.

During play there are set calls for lets, corrections, misconduct, service faults, coaches and injuries. The facts below cover the definitions, the announcements that start and end games and the calls used during play, including those around a challenge.
