Greek goddess of peace (5)
I believe the answer is:
irene
'greek goddess of peace' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for irene that I've seen before include "Greek goddess of peace (English name)" , "Girl's name; Soames Forsyte's first wife" , "In Greek mythology, the goddess of peace" , "- - Handl, actress" , "Goddess of peace - Byzantine ruler" .)
