IPA: //nɒnˈraɪtə//
KK: /nɑnˈraɪtər/
A person who does not write or create written works.
She is a nonwriter, preferring to express herself through art instead of words.
Nonwriter → It is formed from "non-" (meaning not) and "writer" (from Old English "writere", meaning one who writes). The word "nonwriter" refers to someone who does not write or is not a writer.
Think of 'non-' meaning 'not' and 'writer' as someone who writes — so a nonwriter is simply someone who does not write.
