Church promotion for African country (4)
I believe the answer is:
chad
'african country' is the definition.
(Chad is an example)
'church promotion' is the wordplay.
'church' becomes 'ch' (common abbreviation).
'promotion' becomes 'ad' (ad is a kind of promotion).
'ch'+'ad'='CHAD'
'for' is the link.
(Other definitions for chad that I've seen before include "Feature of controversial election once" , "N central African country" , "African country and lake" , "Landlocked desert country of northern central Africa, formerly a French colony" , "Large, shallow lake in north central Africa" .)
