Spooner’s question on offspring — something dirty (10)
I believe the answer is:
ditchwater
'spooner's' is the definition.
Both the definition and answer are singular nouns.
Perhaps you can see a link between them that I don't see?
'question on offspring something dirty' is the wordplay.
I cannot really understand how this works, but
'on' could be 'at' (I've seen this in other clues) and 'at' is found in the answer.
'something' could be 'it' (I've seen this in other clues) and 'it' is found in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for ditchwater that I've seen before include "What credit (anag.)" , "proverbially dull" .)
