Referring to the Spanish dance (4)
I believe the answer is:
reel
'dance' is the definition.
(reel is a kind of dance)
'referring to the spanish' is the wordplay.
'referring to' becomes 're'.
'the spanish' becomes 'el'.
're'+'el'='REEL'
(Other definitions for reel that I've seen before include "Film spool" , "Part of a film; stagger" , "Dance - sway - cotton holder" , "Something to fish with" , "Dance - swim" .)
