And now for something completely different…
When addressed to a person or group of people, a sentence that names said person(s) ought to have a comma in place like this:
Michael, take out the trash.
But it seems to be going by the wayside. You’re hard-pressed to find, “Michael take out the trash” but “Hi Betty” and “Welcome tourists” are fairly ubiquitous. (And technically not correct.)
However, many say that conventions of grammar, usage, punctuation, etc. do and should follow how people actually speak, write, and use words.
So will the Vocative Comma go the way of the Oxford Comma?
Reader, I hope not.
