I liked revelation, because the character I'm using it for is a monotheist, sort of the setting's equivalent of a Christian. The others are nice, though. Thanks, and feel free to keep 'em coming.
What about differences in styles of magic?
For instance, I'm using invocation to representing infusing the energy of some outer source into a creature or object. 'Bull's strength' would be an invocation.
Evocation is calling forth power into an exterior display. 'Fireball' would be an evocation.
Conjuring creates objects. Summoning is illegal, so the term isn't often used.
Revelation is a general term for learning things beyond normal senses. Divination is learning about future events. Scrying is seeing from afar.
Warding deals with intangible protection, including defenses against hostile magic. This is contrasted with something like stoneskin, which would be an invocation.
