How old is fruit or feathers? (7)
I believe the answer is:
plumage
'feathers?' is the definition.
(I've seen this in another clue)
'how old is fruit' is the wordplay.
I cannot really understand how this works, but
'fruit' could be 'plum' (plum is a kind of fruit) and 'plum' is located in the answer.
'how old' could be 'age' (I've seen this before) and 'age' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'or' acts as a link.
Can you help me to learn more?
(Other definitions for plumage that I've seen before include "coat" , "A bird's feathers, may be fancy" , "Birds' clothing" , "Bird's covering of feathers" , "Cover for diver" .)
