Peace offering for woman at certain bank (5,6)
I believe the answer is:
olive branch
'peace offering' is the definition.
(synonyms)
'woman at certain bank' is the wordplay.
'woman' becomes 'Olive' (woman's name).
'at' is a charade indicator (letters next to each other).
'certain bank' becomes 'branch' (I can't justify this - if you can you should give a lot more credence to this answer).
'olive'+'branch'='OLIVE BRANCH'
'for' is the link.
Can you help me to learn more?
(Other definitions for olive branch that I've seen before include "One offered in peace" , "Emblem of peace" , "that will come to a 'sticky' end" , "Symbol of peace" , "Child reading prayer book" .)
