Dance in rehearsals again (5)
I believe the answer is:
salsa
'dance' is the definition.
(type of dance)
'in rehearsals again' is the wordplay.
'in' says the answer is hidden in the clue.
'SALSA' is hidden within 'rehearsals again'.
(Other definitions for salsa that I've seen before include "that's rather spicy!" , "The Latin-American sound" , "fling?" , "Latin American dance - spicy Mexican sauce" , "hot stuff" .)
