Nick not visiting church (5)
I believe the answer is:
notch
'nick' is the definition.
(both can mean a small cut or impression)
'not visiting church' is the wordplay.
'visiting' is a charade indicator (letters next to each other).
'church' becomes 'ch' (common abbreviation).
'not'+'ch'='NOTCH'
(Other definitions for notch that I've seen before include "Incision; indentation" , "Mark indented in wood etc" , "Small V-shaped cut or indentation" , "small score?" , "Salad plant, garnish" .)
