Wife throws drunkard out, being a studious person (4)
I believe the answer is:
swot
'a studious person' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see a link between them that I don't see?
'wife throws drunkard out' is the wordplay.
I cannot really see how this works, but
'wife' could be 'w' (abbreviation) and 'w' is present in the answer.
'drunkard' could be 'sot' (synonyms) and 'sot' is present in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).
'being' is the link.
Can you help me to learn more?
(Other definitions for swot that I've seen before include "Study assiduously" , "Mug up" , "One studying too much" , "Hard worker" , "Hard-working student" .)
