Whine once undressed, overwhelmed by middle’s size (10)
I believe the answer is:
corpulence
'size' is the definition.
The answer and definition can be both human attributes as well as being singular nouns.
Maybe there's an association between them I don't understand?
'whine once undressed overwhelmed by middle's' is the wordplay.
'whine' becomes 'pule' (I've seen this in another clue).
'once undressed' becomes 'nc' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'overwhelmed by' indicates putting letters inside (inserted letters get absorbed or overwhelmed).
'middle' becomes 'core' (I've seen this in another clue).
'pule'+'nc'='pulenc'
'pulenc' inserted into 'core' is 'CORPULENCE'.
Can you help me to learn more?
(Other definitions for corpulence that I've seen before include "Excessive fatness" , "obesity" .)
