Follower of Oscar was vacantly offering fruit (6)
I believe the answer is:
papaws
'fruit' is the definition.
(I've seen this before)
'follower of oscar was vacantly' is the wordplay.
I cannot really see how this works, but
an anagram of 'was' is 'aws' which is present in the answer.
The remaining letters 'pap' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'offering' acts as a link.
Can you help me to learn more?
(Another definition for papaws that I've seen is " Items of exotic fruit".)
