Bones coming from fish, I must conclude (5)
I believe the answer is:
carpi
'bones' is the definition.
(I've seen this before)
'fish i must conclude' is the wordplay.
I cannot really see how this works, but
'fish' could be 'carp' (carp is a kind of fish) and 'carp' is present in the answer.
'i' is present in the answer.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'coming from' acts as a link.
Can you help me to learn more?
(Another definition for carpi that I've seen is " Wrist bones - Capri (anag)".)
