She makes peace in Greece (5)
I believe the answer is:
irene
'she' is the definition.
(I've seen this before)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for irene that I've seen before include "In Greek mythology, the goddess of peace" , "Girl of peace" , "Female name" , "- - Worth, actress" , "woman" .)
