Outsider
Outsider is a piece of gamer slang that originated from Dungeons & Dragons 3rd Edition, though technically originated in 2e under the strange name Planar Monster, where it was the creature type used to refer to any and all creatures native to planes other than the Prime Material Plane. This handy way to collectively refer to Angels, Fiends, and all of the other, weirder planar monsters (Except Elementals, which are their own type if you aren't playing Pathfinder) meant it was readily absorbed into the gamer lexicon. Whilst creatures such as fey and aberrations were their own distinct creature types in 3e, they are also sometimes lumped under the Outsider moniker in casual conversation, since in many campaign settings they fit the basic definition of "creature from another plane" (aka the Plane of Faerie and the Far Realm).
A notable subtype of Outsider is the Native Outsider; this represents a creature with a particularly strong tie to both the Prime Material and another plane. This means it can be the target of Raise Dead spells, unlike normal Outsiders.
