Acknowledgment (without 'e') and acknowledgement (with 'e') are both correct in British English. This post acknowledges the pesky spelling of acknowledg(e)ment.If the verb ends in -e, where does that letter go when you add the -ment? Acknowledgments and jurats are different notarizations with different purposes, each requires its own certificate wording. In standard American English, "acknowledgments" is spelled without the additional "e. " This is largely true in Canada as well. However, if you're writing in British English, it's best to avoid the versions without an "e" altogether. Notaries often encounter confusing situations when filling out certificate wording. British English keeps the "e" and uses acknowledgement, while American English drops the final "e" and uses acknowledgment. Acknowledgements are usually made when some sort of research contribution is made voluntarily for the sake of science.
