Adult fat in every direction (6)
I believe the answer is:
around
'fat in every direction' is the definition.
Both the definition and answer are adjectives. Maybe you can see an association between them that I can't see?
'adult' is the wordplay.
I cannot really see how this works, but
'adult' could be 'a' (abbreviation) and 'a' is found within the answer.
The remaining letters 'round' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for around that I've seen before include "Close to" , "On every side" , "About, here and there in circular way?" , "On all sides or near" , "Somewhere in the vicinity" .)
