En route is correct and means on the way.
In route is incorrect in standard English.
Example: I am en route to the office right now.
I used to write in route in emails without thinking twice. It sounded right to me because it felt like normal English. One day, a client corrected it to en route, and I realized I had been using the wrong phrase in professional communication.
That pushed me to dig deeper into its meaning, origin, and correct usage. I learned that en route is a French phrase adopted into English, and using the correct form improves clarity and credibility.
Since then, I always double check such phrases before using them. If you have made the same mistake, this guide will help you understand and fix it completely.
