Ties up in changing rooms (5)
I believe the answer is:
moors
'ties up' is the definition.
The answer and definition can be both to do with contact as well as being verbs in their -s form.
Perhaps there's an association between them I don't understand?
'changing rooms' is the wordplay.
'changing' indicates anagramming the letters.
'rooms' anagrammed gives 'MOORS'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for moors that I've seen before include "Berths" , "Secures" , "wild places" , "Conquerors once" , "Ties up (vessel)" .)
