The Origin of In Route or En Route
The phrase en route comes directly from French. In French:

Together, en route literally means “on the way.”
English borrowed the phrase without changing its spelling. Over time, many English speakers assumed it followed normal English prepositions and began writing in route instead. This created confusion, especially in casual writing.
However, grammar guides and dictionaries were never accepted in route as standard usage. The original French form remains the correct one.
