Feathers or fruit seen on time (7)
I believe the answer is:
plumage
'feathers' is the definition.
(I've seen this before)
'fruit seen on time' is the wordplay.
'fruit' becomes 'plum' (plum is a kind of fruit).
'seen on' says to put letters next to each other.
'time' becomes 'age' (an age is a period of time).
'plum'+'age'='PLUMAGE'
'or' is the link.
(Other definitions for plumage that I've seen before include "coat" , "Bird's covering of feathers" , "One's feathers" , "A bird's feathers, may be fancy" , "Birds' clothing" .)
