Acknowledgement or Acknowledgment – Quick Answer
Both acknowledgement and acknowledgment are correct.
- Acknowledgment (without the extra “e”) is preferred in American English.
- Acknowledgement (with the extra “e”) is preferred in British English and most Commonwealth countries.
Examples:
- 🇺🇸 American English:
We received your acknowledgment of the complaint. - 🇬🇧 British English:
We received your acknowledgement of the complaint.
The meaning is exactly the same. Only the spelling changes.
The Origin of Acknowledgement or Acknowledgment
The word comes from the verb “acknowledge.”
“Acknowledge” comes from Middle English knowlechen, which meant “to admit” or “to recognize.” Over time, it became “acknowledge.”
When the noun form developed, writers added the suffix -ment. That created:
- acknowledge + ment = acknowledgment / acknowledgement
In early English, both spellings were used. Over time, American English simplified many words by removing silent letters. That is why acknowledgment became standard in the United States.
British English kept the extra “e,” forming acknowledgement.
This pattern is common in English spelling history.
