Did groom turn up by day to accept bride, primarily? (6)
I believe the answer is:
combed
'did groom' is the definition.
(combing is a kind of grooming)
'turn up by day to accept bride primarily?' is the wordplay.
'turn up' becomes 'come' (both can mean to arrive).
'by' is a charade indicator (letters next to each other).
'day' becomes 'd' (abbreviation for day).
'to accept' indicates putting letters inside.
'primarily?' indicates taking the first letters (I've seen 'primarily' mean this).
The first letter of 'bride' is 'b'.
'come'+'d'='comed'
'comed' going around 'b' is 'COMBED'.
(Another definition for combed that I've seen is " searched".)
