Dull dream-girl for Spooner (9)
I believe the answer is:
dishwater
'spooner' is the definition.
Both the answer and definition are singular nouns.
Maybe you can see a link between them that I can't see?
'dull dream-girl' is the wordplay.
I cannot quite see how this works, but
'girl' could be 'dis' (I've seen this in other clues) and 'dis' is present in the answer.
This explanation may well be incorrect...
'for' is the link.
Can you help me to learn more?
(Other definitions for dishwater that I've seen before include "Sink liquid" , "Dirty washing-up liquid?" , "Ultimately it could go down the sink" , "Weak or soiled liquid" .)
