Travel free over the Orient (4)
I believe the answer is:
ride
'travel' is the definition.
(riding is a kind of travelling)
'free over the orient' is the wordplay.
'free' becomes 'rid' ('rid' can be a synonym of 'free'**).
'over' says to put letters next to each other.
'the orient' becomes 'e'.
'rid'+'e'='RIDE'
(Other definitions for ride that I've seen before include "badger" , "Journey on horseback" , "spin > lift > pedal" , "Go by bicycle" , "Journey as passenger" .)
