In a manner that is opposite to or contrasts with a typical example or pattern.
From anti- (against, opposite) + typical (representative of a type) + -ly (adverbial suffix). The word evolved to describe behavior or characteristics that go against what is normally expected.
This word perfectly captures situations where something breaks the mold—like a shy comedian or a clumsy dancer—where the thing is the opposite of its category's stereotype. It's the linguistic way of saying 'you wouldn't expect it, but here it is.'
