Group with single in commercial scrapped (9)
I believe the answer is:
abandoned
'scrapped' is the definition.
(I've seen this in another clue)
'group with single in commercial' is the wordplay.
'group' becomes 'band' (band can mean a group of people).
'with' is a charade indicator (letters next to each other).
'single' becomes 'one' (a single thing - only one).
'in' means one lot of letters goes inside another.
'commercial' becomes 'ad' (abbreviation for advertisement).
'band'+'one'='bandone'
'bandone' inserted within 'ad' is 'ABANDONED'.
(Other definitions for abandoned that I've seen before include "marooned" , "Crazy!" , "without any reservations at all" , "Rejected" , "Left in the lurch, forsaken" .)
