Latin American dance additionally used briefly in South Africa (5)
I believe the answer is:
salsa
'latin american dance' is the definition.
(style of Latin American dance)
'additionally used briefly in south africa' is the wordplay.
'additionally' becomes 'also' (I've seen this before).
'used briefly' means to remove the last letter.
'in' indicates putting letters inside.
'south africa' becomes 'SA' (abbreviation).
'also' with its last letter taken away is 'als'.
'als' going within 'sa' is 'SALSA'.
(Other definitions for salsa that I've seen before include "Tomato relish" , "Saucy dance" , "that's hot and saucy?" , "Dance or a dip?" , "dressing" .)
