Drive away quietly during the dance (5)
I believe the answer is:
repel
'drive away' is the definition.
(to repel is to drive away)
'quietly during the dance' is the wordplay.
'quietly' becomes 'p' (p for piano and quiet).
'during' indicates putting letters inside.
'the dance' becomes 'reel' (reel is a kind of dance).
'p' put inside 'reel' is 'REPEL'.
(Other definitions for repel that I've seen before include "Drive away like leper" , "Fend off" , "Drive back like leper" , "Drive back or disgust" , "Spurn" .)
