Wearer of baggy trousers (4)
I believe the answer is:
user
'wearer' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps there's an association between them I don't understand?
'of baggy trousers' is the wordplay.
'of' indicates the answer is hidden within the clue.
'USER' can be found hidden inside 'baggy trousers'.
Can you help me to learn more?
(Other definitions for user that I've seen before include "One who employs" , "Drug taker" , "Drug addict (informal)" , "Operator; exploiter" , "Drug-taker" .)
