Wearers of short trousers (5)
I believe the answer is:
users
'wearers' is the definition.
The answer and definition can be both people as well as being plural nouns.
Perhaps there's an association between them I don't understand?
'short trousers' is the wordplay.
'USERS' is hidden within the letters.
However, I'm uncertain how the hidden word is indicated.
'of' is the link.
Can you help me to learn more?
(Other definitions for users that I've seen before include "People with a drug habit" , "Drug addicts" , "subscribers" , "Utilisers" , "Ruses for employers" .)
