Unripe grapes are too much for her (3)
I believe the answer is:
peg
'her' is the definition.
(I've seen this before)
'unripe grapes are too much' is the wordplay.
'PEG' is hidden in amongst the letters.
However, I'm uncertain how the hidden word is indicated.
'for' acts as a link.
Can you help me to learn more?
(Other definitions for peg that I've seen before include "Brandy and soda drink measure" , "Small cylindrical pin" , "Member" , "that may have hat or coat on" , "Wooden pin, small marker" .)
