On the way from France? (2,5)
I believe the answer is:
en route
'on the way' is the definition.
(synonyms)
I don't understand the rest of the clue.
Can you help me to learn more?
(Other definitions for en route that I've seen before include "March" , "'On the way (2,5)'" , "Along the way" , "on the road" , "As part of a journey" .)
