Do you separate a persons titles with commas. For example the Reverend Dr. so and so?

You are correct! You do separate titles like "Reverend Dr." with a comma.

Here's how it works:

* Use a comma after each title before the person's name.

* Don't use a comma after the person's name.

Example:

* Correct: The Reverend Dr. Smith will be speaking at the conference.

* Incorrect: The Reverend, Dr. Smith will be speaking at the conference.

Reasoning:

This is a matter of style and clarity. The commas help to distinguish the titles from the person's name. They also make the sentence easier to read and understand.
