Calls for or asks round (7)
I believe the answer is:
invites
I believe this clue is a double definition.
'calls for' is the first definition.
('invite' can be a synonym of 'call for')
'asks round' is the second definition.
('invite' can be a synonym of 'ask round')
(Other definitions for invites that I've seen before include "Requests the presence of" , "Asks" , "Solicits" .)
