It’s vegetable, but may have fur on it (5)
I believe the answer is:
fruit
'it' is the definition.
The definition suggests a singular noun which matches the answer.
'it's vegetable but may have fur' is the wordplay.
I cannot really see how this works, but
'it's' could be 'it' (I've seen this in other clues) and 'it' is found in the answer.
an anagram of 'fur' is 'fru' which is located in the answer.
No letters remain.
This explanation may well be incorrect...
'on' is the link.
Can you help me to learn more?
(Other definitions for fruit that I've seen before include "Eg, bananas" , "Seed-bearing growth" , "Eg, apple or pear" , "Orange, lemon" , "Kiwi, mandarin etc" .)
