Get on in Far East (4)
I believe the answer is:
fare
'get on' is the definition.
(I've seen this in another clue)
'far east' is the wordplay.
'east' becomes 'E' (synonyms).
'far'+'e'='FARE'
'in' is the link.
(Other definitions for fare that I've seen before include "Food, or price of bus ticket" , "Taxi charge; food" , "(Person paying) price for travel" , "Range of food; travel" , "Grip (of a tyre)" .)
