A man bringing a sailor back to a dance (5)
I believe the answer is:
samba
'to a dance' is the definition.
(Brazilian dance)
'a man bringing a sailor back' is the wordplay.
'a man' becomes 'sam' ().
'bringing' is a charade indicator (letters next to each other).
'a sailor' becomes 'ab' (abbreviation for able seaman).
'back' says the letters should be written backwards.
'ab' in reverse letter order is 'ba'.
'sam'+'ba'='SAMBA'
(Other definitions for samba that I've seen before include "it was launched in Brazil" , "Dance music" , "Brazilian dance" , "This ambassador's > brisk steps" , "moves from Brazil" .)
