Prefix with -phyte (3)
I believe the answer is:
neo
'prefix with phyte' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for neo that I've seen before include "Hero of The Matrix films; new (prefix)" , "Prefix meaning new - try one" , "Prefix donating new" , "New (suffix)" , "Prefix meaning new of modern form of" .)
