Female, no spring chicken, finds wallet (6)
I believe the answer is:
folder
'wallet' is the definition.
(a wallet for documents)
'female no spring chicken' is the wordplay.
'female' becomes 'f' (common abbreviation).
'no spring chicken' becomes 'older' (I am not sure about this - if you are sure you should believe this answer much more).
'f'+'older'='FOLDER'
'finds' acts as a link.
Can you help me to learn more?
(Other definitions for folder that I've seen before include "Thin file for papers" , "Binder" , "Document cover" , "Cover for loose papers" , "Wallet (for papers)" .)
