Most spellcasters have some sort of spoken component to their magic—activating words, ritual chants, and so on. These words are always in a language that isn’t their native one. If a wizard casts spells using words he commonly uses or hears in a context other than casting spells, there’s too much risk of his magical power finding expression every single time he says something, potentially creating a nasty sideeffect. Putting the spells in a different language acts as a form of mental insulation, making sure that he doesn’t accidentally loose power at a target (or fry his own mind) every time he swears.
