Not typical; not conforming to a type or normal standard; unusual or atypical.
From prefix 'a-' (not) + 'typic' (from Greek 'typikos,' meaning 'of or belonging to a type'). The Greek root 'typos' originally meant 'blow' or 'mark,' then evolved to mean 'impression' or 'model.' The 'a-' prefix negates the quality of being typical.
While 'atypical' is the common form today, 'atypic' is its slightly older sibling that doctors and scientists still use, especially when describing unusual medical cases or specimens. The medical world loves short, punchy Latin-based words, so 'atypic' cells and 'atypic' presentations show up in journals and case studies.
