Make it OK for one to call? (7)
I believe the answer is:
entitle
'make it' is the definition.
The definition and answer can be both to do with social activities as well as being verbs in their base form.
Perhaps there's a link between them I don't understand?
'ok for one to call?' is the wordplay.
'ok for one' becomes 'en' (I can't explain this - if you can you should believe this answer much more).
'to call?' becomes 'title' (titling is a kind of calling).
'en'+'title'='ENTITLE'
Can you help me to learn more?
(Other definitions for entitle that I've seen before include "Call; permit" , "Allow" , "Warrant" , "Style; give right to" , "Name; enable" .)
