Chuck seen in highland dance (5)
I believe the answer is:
fling
I believe this is a double definition.
'chuck' is the first definition.
(I've seen this in another clue)
'highland dance' is the second definition.
(I've seen this before)
'seen in' acts as a link.
(Other definitions for fling that I've seen before include "Toss" , "Highland dance - spell of way-out behaviour" , "Brief amour; throw" , "Throw, cast" , "Throw angrily in spell of indulgent pleasure" .)
