Go round in high circles (5)
I believe the answer is:
orbit
'go round' is the definition.
(I've seen this before)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for orbit that I've seen before include "Satellite's path" , "Planet's path" , "Path through space" , "E.g. planetary movement" , "Lunar trajectory" .)
