Give a lift to outcast with no heart for dance (4)
I believe the answer is:
reel
'for dance' is the definition.
(reel is a kind of dance)
'give a lift to outcast with no heart' is the wordplay.
'give a lift' shows that the letters should be reversed in order (I've seen 'given a lift' mean this).
'to outcast' becomes 'leper' (leper is a kind of outcast).
'with no heart' means to remove the middle letters.
'leper' with its centre taken out is 'leer'.
'leer' back-to-front is 'REEL'.
(Other definitions for reel that I've seen before include "Stagger about in lively dance" , "Stagger with rod winder" , "unwind?" , "Fishing rod attachment" , "Revolving spool" .)
