Not conforming to a type; deviating from the typical or standard form.
From ex- (outside, without) + typal (from Greek 'typos' meaning type or mark), this rare term was formed to describe things that don't fit the expected pattern or category.
This word is so obscure that even most dictionaries skip it, but it perfectly captures the idea of something being an exception to the rule—like finding a dog that's afraid of other dogs.
