Greek goddess of victory (4)
I believe the answer is:
nike
'greek goddess of victory' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nike that I've seen before include "Goddess of victory - clothing company" , "Victoria" , "bringer of victory" , "Greek winged goddess of victory, and sports goods logo" , "Greek goddess, personification of victory" .)
