Meaning of Each Word

  • En Route (French for “on the way”) is used to indicate that someone or something is in transit or on their way to a destination.
    • Example: “The package is en route to your home.”
  • In Route is a mistaken variation. Though often heard in conversation, it doesn’t hold up grammatically. The correct form is en route.

Grammar Rule Explained

The phrase en route comes from French, where “en” means “on” and “route” means “way” or “road.” This makes “en route” the correct expression for referring to someone or something that is currently traveling or heading to a destination.

In route is not a grammatically correct expression in English. Despite this, people occasionally use “in route” instead of “en route,” which grammar experts consider a mistake.

Example Sentences

Common Mistakes People Make

  • Using in route instead of en route.
  • Saying “I’ll be in route to the airport” instead of “I’ll be en route to the airport.”
  • Misunderstanding the origin of the phrase and using it incorrectly in formal writing.

Easy Trick to Remember the Difference

To help remember, think of the French “en” meaning “on.” En route literally translates to “on the way,” which makes sense when describing transit. Simply remember: “En = On,” and “in” doesn’t fit in the phrase.

When to Use Each Word

  • En Route: Use it when you want to describe someone or something that is on the way to a destination. For example, use it in everyday conversation, emails, or business correspondence when referring to travel or delivery.
    • Correct: “The package is en route and should arrive by tomorrow.”
  • In Route: Avoid using in route at all, as it is grammatically incorrect.
    • Incorrect: “The truck is in route to the warehouse.”
