Commercial bishop and vicar turned over quickly? (6)
I believe the answer is:
adverb
'over quickly?' is the definition.
I can't judge whether this defines the answer.
'commercial bishop and vicar turned' is the wordplay.
'commercial' becomes 'ad' (abbreviation for advertisement).
'bishop' becomes 'B' (chess abbreviation).
'and' is a charade indicator (letters next to each other).
'vicar' becomes 'rev' (short for reverend).
'turned' says the letters should be written in reverse.
'rev' backwards is 'ver'.
'b' put after 'ver' is 'verb'.
'ad'+'verb'='ADVERB'
Can you help me to learn more?
(Other definitions for adverb that I've seen before include "fast, maybe?" , "Word that qualifies an action" , "Perhaps stupidly" , "Verb qualifier" , "Term of modification" .)
