She made peace in Greece (5)
I believe the answer is:
irene
'she' is the definition.
(I've seen this before)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for irene that I've seen before include "US actress, -- Dunne" , "Goddess of peace - Byzantine ruler" , "Female name" , "- - Handl, actress" , "Representative of peace" .)
