A modern prefix (3)

I believe the answer is:

neo

'a modern prefix' is the definition.
(I've seen this in another clue)

This is all the clue.

(Other definitions for neo that I've seen before include "Prefix meaning new of modern form of" , "Prefix meaning new or recent" , "language" , "Hero of The Matrix films; new (prefix)" , "New (suffix)" .)

I've seen this clue in the Evening Standard.
