Persona __ grata (3)

I believe the answer is:

non

(Other definitions for non that I've seen before include "Combining form meaning not" , "Prefix meaning not or none" , "Prefixed negation of a word" , "Negative French word" , "Prefix meaning negative" .)

I've seen this clue in the LA Times, the Newsday and the USA Today.
