Fuss about vocal, never ending, Green? (7)
I believe the answer is:
avocado
'green?' is the definition.
(I've seen this before)
'fuss about vocal never ending' is the wordplay.
'fuss' becomes 'ado' (synonyms).
'about' indicates putting letters inside.
'never ending' means to remove the last letter.
'vocal' with its last letter taken off is 'voca'.
'ado' enclosing 'voca' is 'AVOCADO'.
(Other definitions for avocado that I've seen before include "Tropical salad ingredient" , "Tropical tree - edible green-skinned fruit" , "Greenish-colour" , "Alligator pear" , "Pulpy fruit" .)
