Tap or tango (5)
I believe the answer is:
dance
I believe this is a double definition.
'tap' is the first definition.
(I know this)
'tango' is the second definition.
(thesaurus)
(Other definitions for dance that I've seen before include "See 4" , "Flamenco, perhaps" , "Waltz, say" , "Move in time to music" , "Steps" .)
