Make a fuss about a Greek island (6)
I believe the answer is:
Here is my best explanation:
'make a fuss' is the definition.
(I've seen this before)
'about a greek island' is the wordplay.
'about' is an insertion indicator.
'greek island' becomes 'crete' (I've seen this before).
'a' going within 'crete' is 'CREATE'.
