Change direction of tour, moving east (7)
I believe the answer is:
reroute
'change direction' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for reroute that I've seen before include "Send elsewhere" , "Send a different way" , "Change direction" , "Divert" , "Send on different path" .)
