Wearer of the trousers (4)
I believe the answer is:
user
'wearer' is the definition.
The definition and answer can be both people as well as being singular nouns.
Maybe they are linked in a way I don't understand?
'of the trousers' is the wordplay.
'of' indicates a hidden word.
'USER' can be found hidden inside 'trousers'.
Can you help me to learn more?
(Other definitions for user that I've seen before include "Someone who exploits another" , "Drug addict (colloq.)" , "Manipulative woman" , "Operator; exploiter" , "Drug taker" .)
