After church I'll relax (5)
I believe the answer is:
chill
'relax' is the definition.
(I've seen this before)
'after church i'll' is the wordplay.
'after' is a charade indicator (letters next to each other).
'church' becomes 'ch' (common abbreviation).
'ch'+'ill' is 'CHILL'.
(Other definitions for chill that I've seen before include "This disheartens" , "Sharp cold" , "A feeling of coldness" , "Make cold; relax" , "Refrigerate" .)
