It isn't much to ask for (7)
I believe the answer is:
modicum
'it isn't much to ask for' is the definition.
The definition suggests a singular noun which matches the answer.
This is all the clue.
Can you help me to learn more?
(Other definitions for modicum that I've seen before include "A small portion" , "Little bit" , "dash" , "Token amount" , "touch" .)
