Give notice to cleric (10)
I believe the answer is:
administer
'give' is the definition.
(administering is a kind of giving)
'notice to cleric' is the wordplay.
'notice' becomes 'ad' (both can mean an advertisement).
'to cleric' becomes 'minister'.
'ad'+'minister'='ADMINISTER'
(Other definitions for administer that I've seen before include "act as manager" , "Oversee" , "Deal out (punishment)" , "man?" , "give" .)
