This is a Community Wiki containing a list of terms specific to the D&D game with which outsiders looking to enter may not be familiar.
Dungeons and Dragons may share some terminology with the rest of the RPG world in general, but generic terms are recorded in the Glossary of Common RPG Terminology. If however, there are D&D-specific variations of common terms, or there are some common terms which have different D&D-specific meanings, please do include them here.
This query is meant to include all editions of Dungeons and Dragons. If some terminology is exclusive to a certain edition(s), or changes meaning between editions, please include that information in the definition.
