A person connected with something — with God? (6)
I believe the answer is:
wallah
'a person connected with something' is the definition.
I can't judge whether this defines the answer.
'with god?' is the wordplay.
'with' becomes 'w' (abbreviation).
'god?' becomes 'Allah' (Arabic name for God).
'w'+'allah'='WALLAH'
Can you help me to learn more?
(Other definitions for wallah that I've seen before include "top specialist" , "Person in charge of (or specialised in) something (from Hindi)" , "man in particular role" , "Indian worker" .)
