Some marvellous entertainment making one ecstatic (4)
I believe the answer is:
sent
'one ecstatic' is the definition.
(I've seen this in other clues)
'some marvellous entertainment making' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'SENT' is hidden in the letters of 'marvellous entertainment making'.
(Other definitions for sent that I've seen before include "Remitted" , "Thrilled" , "Shipped" , "Posted" , "Caused to go somewhere" .)
