Term
Rally
The continuous play from the serve until the ball becomes dead.
The continuous play from the moment the serve is hit until the ball becomes a dead ball (Section 2, Definitions).
A rally ends not only with a fault, but also when the ball becomes dead because of a hinder, a line call, and so on (9.B, 9.C, 8.F.2).
How to read the sources: numbers like (8.F.4) are rulebook sections, and links are outside sources. An "Author's note" is the author's personal experience, not an official rule.
