Q. In the phrase “today, tomorrow, & always” should the comma before the ampersand be removed?

Q. Is a comma used after “But” or “And” at the beginning of a sentence?

Q. Greetings! I edit a lot of romance novels, which generally have a light, informal tone, but the publisher I work with likes to stick to strict Chicago style unless an author objects. I often struggle with constructions like this one, which I found in the Chicago forum: “My wife’s, Deb’s, father passed away on Sunday.” I would write/edit that as “My wife Deb’s father passed away on Sunday,” although the publisher would likely object because strict Chicago style says to put commas around “wife.” But I think that would sound awful. I would appreciate if you could weigh in on this. Thanks!

Q. I work with many first-time authors, and many of them want to argue about commas. Of course as author, they have the final decision of their own work . . . but I keep running into the idea of breath: “My high school English teacher taught me that commas go where you want to take a breath, so that’s why this comma should be here.” What would you say to these authors?

Q. Chicago says commas aren’t needed with “not only . . . but also” constructions but are needed between two independent clauses joined by a coordinating conjunction. So which wins when you have both?

Q. Hi. A fiction author of ours hates the word that and often replaces it with a comma. For example: “The interior was so dark, she made out only shadowy shapes.” And “Her eyes fell on a cup, and a memory rose up with such clarity, she released a little gasp.” In such cases, we might offer her suggestions to rephrase, but would you let the commas stand? Or would you consider these sentences to have comma splices? This comes up a lot in fiction with other authors, too, so we’d love to hear your opinion! Thanks.

Q. Can you clarify when commas should be used with an “or” phrase? For example, should it be “Table salt, also known as sodium chloride or NaCl” or “Table salt, also known as sodium chloride, or NaCl”?

Q. According to CMOS 6.51, “Expressions of the type that is are traditionally followed by a comma. They are best preceded by an em dash or a semicolon rather than a comma, or the entire phrase they introduce may be enclosed in parentheses or em dashes.” My question is this: Would it still be acceptable to use a comma in such expressions rather than the em dash or parentheses? Thank you!

Q. When an expression like “11 minutes, 52 seconds” occurs in the middle of a sentence (as in “We finished 11 minutes, 52 seconds ahead of the next car”), is a second comma required? If not, why?

Q. I don’t understand why the following example in the serial comma section (CMOS 6.19) is not considered a comma splice: “Paul put the kettle on, Don fetched the teapot, and I made tea.”
