Dance from part of east Angola (5)
I believe the answer is:
tango
'dance' is the definition.
(tango is a type of dance)
'part of east angola' is the wordplay.
'part of' indicates the answer is hidden within the clue.
'TANGO' is hidden within 'east angola'.
'from' is the link.
(Other definitions for tango that I've seen before include "Letter T in radio comms" , "Latin American dance (requiring two?)" , "Latin American dance takes two to do it" , "Tonga (anag.)" , "Movement from Argentina" .)
