Confused daughter is taken to gig by boy (12)
I believe the answer is:
disconcerted
'confused' is the definition.
('disconcert' can be a synonym of 'confuse')
'daughter is taken to gig by boy' is the wordplay.
'daughter' becomes 'dis' (I've seen this in other clues).
'is taken to' means one lot of letters go next to another.
'gig' becomes 'concert'.
'by' is a charade indicator (letters next to each other).
'boy' becomes 'ed'.
'dis'+'concert'+'ed'='DISCONCERTED'
(Other definitions for disconcerted that I've seen before include "Disturbed the composure of" , "All shook up"" , "Second credit (anag) - thrown" , "Unsettled" .)
