# Role-playing game terms

Role-playing games (RPGs) have developed specialized terminology. This includes both terminology used within RPGs to describe in-game concepts and terminology used to describe RPGs. Role-playing games also have specialized slang and jargon associated with them.
Besides the terms listed here, there are numerous terms used in the context of specific, individual RPGs such as Dungeons & Dragons (D&D), Pathfinder, Fate, and Vampire: The Masquerade. For a list of RPGs, see List of role-playing games.
