To get around, you need a curved path (5)
I believe the answer is:
orbit
This clue is a double definition.
'to get around' is the first definition.
(I've seen this in another clue)
'a curved path' is the second definition.
(I've seen this in another clue)
'you need' is the link.
(Other definitions for orbit that I've seen before include "Path of planet around sun" , "Path through space" , "area of activity" , "Area of influence - eye socket" , "Circling path" .)
