Concerning conflict surrounding fish figure (9)
I believe the answer is:
rectangle
'figure' is the definition.
(rectangle is a kind of figure)
'concerning conflict surrounding fish' is the wordplay.
I cannot really understand how this works, but
'concerning' could be 're' (both can mean on a particular topic) and 're' is found in the answer.
'fish' could be 'angle' (angle can mean to fish) and 'angle' is located in the answer.
The remaining letters 'ct' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for rectangle that I've seen before include "Four-sided figure" , "Geometric figure with four right angles, not square" , "regular sort of figure" , "box" , "Figure on plane" .)
