Seconds required with some sterling seafood (5)
I believe the answer is:
squid
'seafood' is the definition.
(I know that squid is a type of seafood)
'seconds required with some sterling' is the wordplay.
I cannot really understand how this works, but
'seconds' could be 's' (abbreviation) and 's' is found in the answer.
'sterling' could be 'quid' and 'quid' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for squid that I've seen before include "Eight-armed creature" , "Edible eight-arm mollusc" , "Marine cephalopod" , "Cephalopod mollusc" , "Large cephalopod" .)
