Mage
Mage is a general term used to refer to any character or class that can work arcane magic, giving it a more neutral context (or at least informal tone) than arcanist. Whilst it is usually considered more synonymous with the Wizard, it can also cover Sorcerer, Warlock and Witch.
In Advanced Dungeons & Dragons, "Mage" was sometimes used as a specific name for a non-specialist Wizard, attempting to define a generalist caster in the same way as the Abjurer, Conjurer, Diviner, Enchanter, Evoker, Illusionist, Necromancer, or Transmuter.
