Cuts parts off fish with its middle crooked (8)
I believe the answer is:
lopsided
'crooked' is the definition.
(similar in meaning)
'cuts parts off fish with its middle' is the wordplay.
I cannot quite see how this works, but
'cuts' could be 'lops' (lopping is a kind of cutting) and 'lops' is found in the answer.
'fish' could be 'ide' (type of fish) and 'ide' is found in the answer.
A single letter 'd' remains 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 lopsided that I've seen before include "Crooked" , "Not symmetrical" , "Ill-balanced" , "Asymmetrical" , "Off balance" .)
