Young lads remove skin from fishes (10)
I believe the answer is:
striplings
'young lads' is the definition.
The definition and answer can be both people as well as being plural nouns.
Perhaps there's an association between them I don't understand?
'remove skin from fishes' is the wordplay.
'remove' becomes 'strip' (stripping is a kind of removing).
'skin from fishes' becomes 'lings' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'strip'+'lings'='STRIPLINGS'
Can you help me to learn more?
(Another definition for striplings that I've seen is " youngsters".)
