What does atypical mean? Atypical is used to describe something that does not conform to the norm or that is irregular, such as an atypical behavior or an atypical action. Something that is atypical differs in a noticeable way from other items of its kind. An atypical flower might be a flower that glows in the dark (if you discover one, let us know!). An atypical horror film could be one in which the monster tries to be friends with everyone rather than kill them. Example: These fixtures are atypical of our usual products.

Etymology
Origin of atypical
Explanation
Typical means what you would expect—a typical suburban town has lots of neat little houses and people. Atypical means outside of type—an atypical suburban town might be populated by zombies in damp caves. Atypical is a synonym of "unusual," but it carries a more objective feel—scientific studies might mention atypical results, suggesting that there is a clear definition of what is typical and what is not. "Unusual" is more of a casual observation that one might make in a non-scientific context.
