Famous clown meets fan for something to eat (7)
I believe the answer is:
coconut
'something to eat' is the definition.
(coconut is a kind of food)
'famous clown meets fan' is the wordplay.
'famous clown' becomes 'coco' (Coco the Clown, 20th-century clown).
'meets' means one lot of letters go next to another.
'fan' becomes 'nut' (both can mean an enthusiast).
'coco'+'nut'='COCONUT'
'for' is the link.
(Other definitions for coconut that I've seen before include "Large hard seed" , "Hard thing" , "Palm tree product" , "cut from the palm?" , "Large palm fruit" .)
