Go back to island with it after member of the clergy (7)
I believe the answer is:
revisit
'go back to' is the definition.
(I've seen this in another clue)
'island with it after member of the clergy' is the wordplay.
'island' becomes 'is' (abbreviation).
'with' says to put letters next to each other.
'after' is a charade indicator (letters next to each other).
'member of the clergy' becomes 'rev' (short for reverend).
'is' put next to 'it' is 'isit'.
'isit' after 'rev' is 'REVISIT'.
(Other definitions for revisit that I've seen before include "Pay further call" , "Consider again" , "making further call!" , "repeated call?" , "Reconsider" .)
