Travellers' game (4)
I believe the answer is:
away
'game' is the definition.
(away game is a kind of game)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for away that I've seen before include "Having started" , "constantly" , "Onward" , "Non-home match" , "Not present, having left" .)
