Got an arrangement for Argentinian dance (5)
I believe the answer is:
tango
'argentinian dance' is the definition.
(I've seen this before)
'got an arrangement' is the wordplay.
'arrangement' indicates anagramming the letters.
'got'+'an'='gotan'
'gotan' is an anagram of 'TANGO'.
'for' is the link.
(Other definitions for tango that I've seen before include "Dance originally from Buenos Aires" , "tee" , "Tonga (anag.)" , "Activity requiring two to" , "Dance; letter T" .)
