Religious leader I married in the morning (4)
I believe the answer is:
imam
'religious leader' is the definition.
(I know that imam is a type of religious leader)
'i married in the morning' is the wordplay.
'married' becomes 'm'.
'in the morning' becomes 'am' (AM on a clock).
'i'+'m'+'am'='IMAM'
(Other definitions for imam that I've seen before include "Mosque's prayer leader" , "Muslim religious leader" , "Muslim prayer leader" , "Man leading prayers in a mosque" , "Muslim holy man" .)
