Live comedian by church entrance (7)
I believe the answer is:
bewitch
'entrance' is the definition.
(synonyms)
'live comedian by church' is the wordplay.
'live' becomes 'be' (synonyms).
'comedian' becomes 'wit' (a witty person).
'by' says to put letters next to each other.
'church' becomes 'ch' (common abbreviation).
'be'+'wit'+'ch'='BEWITCH'
(Other definitions for bewitch that I've seen before include "Get intoxicated" , "Captivate" , "Fascinate - charm" , "intrigue" , "Spellbind" .)
