Bone in fish -- meal putting me off (6)
I believe the answer is:
carpal
'bone' is the definition.
(I know that carpal is a type of bone)
'fish meal putting me off' is the wordplay.
I cannot quite understand how this works, but
'fish' could be 'carp' (carp is a kind of fish) and 'carp' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
'in' acts as a link.
Can you help me to learn more?
(Other definitions for carpal that I've seen before include "Type of tunnel producing complaint" , "Wrist-bone" , "Wrist bone" , "Of the wrist bones" , "regarding part of the lower arm" .)
