The Origin of Congrats and Congratulations
The word congratulations comes from the Latin word congratulari, which means “to express joy” or “to wish someone happiness.”
English speakers began using congratulations in the early 1600s, mostly in formal communication and public speeches.
Later, everyday conversation shortened the word into congrats. This process is called clipping in linguistics. English does this often with long words:
- Advertisement → Ad
- Refrigerator → Fridge
- Examination → Exam
In the same way:
- Congratulations → Congrats
Important points:
- Congrats is not slang
- It is a grammatically accepted informal word
- Both words share the same meaning
The only real difference is the level of formality.
