They are often referred to by only the first word of their name. For example, in The Tribe of Rushing Water, a cat's name is said to be the first memorable thing their mother sees after giving birth (such as 'Brook Where Small Fish Swim' or 'Night of No Stars'). This naming convention does not hold for non-Clan characters. A cat may also have their name changed in a special ceremony. If a leader commits a crime, they may be deemed unworthy of their name, stripped of the '-star' suffix, and return to using their warrior name. If a cat becomes a Clan leader, they are granted the suffix '-star' at the end of their name (Bluestar, Bramblestar, Tallstar, etc.). When the character completes their apprenticeship and is promoted to a full warrior or medicine cat, the suffix to their name is then changed to one chosen by the Clan leader or medicine cat (Bluefur, Brambleclaw, Talltail, etc.). Upon becoming an apprentice (a warrior or medicine cat in training), '-paw' replaces '-kit' at the end of the character's name (Bluepaw, Bramblepaw, Tallpaw, etc.). As a kitten, the character's name ends with '-kit' (Bluekit, Bramblekit, Tallkit, etc.). The name's suffix varies through the character's lifespan and position within the Clan, with the bestowing of the new name being a component of the ceremonies marking these role changes. Each cat's name has a prefix (Blue, Bramble, Tall, etc.) which generally stays constant throughout their life.

In the Warriors universe, the characters in the five warrior Clans (ThunderClan, RiverClan, WindClan, ShadowClan, and Sk圜lan) have names composed of two parts.
