I have been noticing that in communication both oral and written, more and more people are using the word “of” as a sentence ender.

“Of“ Is not a word that should be used to end sentences. It’s a word that is better used to link phrases within sentences. If the word inadvertently ends a sentence being written, editing should overcome the issue, with replacement of that word and reallocating it somewhere within the text being written.

When communicating orally carry out mental checks of what you’re saying is you speak. It might be that that word is added in a wrong context during the speech. If you make a mental note of what you’ve just said, it will help you to overcome that same mistake in the future.
