A measured amount of assistance (7)
I believe the answer is:
helping
This clue could be a double definition.
'a measured amount' is the first definition.
'helping' can be an answer for 'amount' (helping is a kind of amount). I'm unsure of the 'a measured' bit.
'assistance' is the second definition.
(synonyms)
'of' acts as a link.
Can you help me to learn more?
(Other definitions for helping that I've seen before include "Assisting" , "Portion; giving aid" , "Giving assistance" , "Amount put on plate" , "Food portion" .)
