Fault

When a rally ends because of a rule violation or a mistake.

When a rally ends because of a rule violation or a mistake (Section 2, Definitions, 9.B). Hitting the ball out (10.C.1), hitting it so that it doesn't cross the net and lands on your own side (10.C.2), and volleying in the non-volley zone (kitchen) (11.A.1) are some examples of faults. The side that commits the fault loses that rally (Section 2, Definitions).

A serve that touches the kitchen line is a fault

This figure is from the rule "A serve that touches the kitchen line is a fault".

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.
