Cleric with kinship to regularly call again (7)
I believe the answer is:
revisit
'call again' is the definition.
('visit' can be a synonym for 'call' so perhaps 'revisit' is OK for 'call again')
'cleric with kinship to regularly' is the wordplay.
'cleric' becomes 'Rev' (abbreviation for Reverend).
'with' says to put letters next to each other.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'kinship'+'to'='kinshipto'
The alternate letters of 'kinshipto' are 'isit'.
'rev'+'isit'='REVISIT'
(Other definitions for revisit that I've seen before include "making further call!" , "Consider again" , "coming to call back?" , "Reconsider" , "repeated call?" .)
