Providing wine during the musical performance (6)
I believe the answer is:
giving
'providing' is the definition.
(giving is a kind of providing)
'wine during the musical performance' is the wordplay.
'wine' becomes 'vin' (I have seen 'French wine ' mean 'vin' so perhaps 'wine' could also mean 'vin').
'during' is an insertion indicator.
'the musical performance' becomes 'gig' (I've seen this before. I am not sure about the 'musical' bit.**).
'vin' placed into 'gig' is 'GIVING'.
Can you help me to learn more?
(Other definitions for giving that I've seen before include "Granting" , "Yielding; presenting" , "Donating" , "Handing over" , "'Friday's child is loving and . . . . . .'" .)
