The Origin of En Route or In Route

The phrase en route comes from French.

In French, en means “on” or “along,” while route means “road” or “way.” Together, en route literally means “on the way.”

English borrowed the phrase many years ago and kept its original French spelling. Because English speakers often hear the phrase without seeing it written, many assume it should be written as “in route.”

This spelling confusion happens because the pronunciation of en route can sound similar to in route in everyday speech.

Why the Spelling Difference Exists

• En route is the original French phrase.
• English adopted the phrase without changing its spelling.
• People who hear the phrase may mistakenly write it as in route.
• Dictionaries and style guides recognize en route as the standard form.
