Limits in rents perhaps (7)
I believe the answer is:
interns
'limits' is the definition.
The answer and definition can be both to do with social activities as well as being verbs in their -s form.
Maybe you can see an association between them that I don't see?
'in rents perhaps' is the wordplay.
'rents perhaps' becomes 'terns' (I can't justify this - if you can you should give a lot more credence to this answer).
'in'+'terns'='INTERNS'
Can you help me to learn more?
(Other definitions for interns that I've seen before include "those confined" , "Hospital residents" .)
