Authentic-sounding Scottish dance? (4)
I believe the answer is:
reel
'scottish dance?' is the definition.
(I've seen this before)
'authentic-sounding' is the wordplay.
'authentic' becomes 'real' (I've seen this before).
'sounding' indicates a 'sounds like' (homophone) clue.
'real' is a homophone of 'REEL'.
(Other definitions for reel that I've seen before include "Highland dance" , "Stagger in Irish dance" , "Something to fish with" , "Cylinder on which something is wound" , "Stagger with rod winder" .)
