Receive cut in advance with enthusiasm (7)
I believe the answer is:
eagerly
'with enthusiasm' is the definition.
(I've seen this before)
'receive cut in advance' is the wordplay.
'receive' becomes 'get' ('get' can be a synonym of 'receive').
'cut' means to remove the last letter.
'in' indicates putting letters inside.
'advance' becomes 'early' ('early' can be similar in meaning to 'advance'**).
'get' with its final letter removed is 'ge'.
'ge' going within 'early' is 'EAGERLY'.
(Other definitions for eagerly that I've seen before include "Ardently and avidly" , "Enthusiastically" , "With keen anticipation" , "anxiously" , "Fervently" .)
