Q. Do you capitalize both words in “happy birthday”?

Q. I have a question regarding an episode my fiction author mentions quite a few times in her story. She’s currently italicizing it: the incident. I think caps would be better: the Incident (“the” not capped). Or would “the” be capped in this case?

Q. Permission forms sometimes use ALL CAPS for authors, titles, or copyright holders—for example, “All Rights Controlled and Administered by [MUSIC PUBLISHER].” Must a credit line copy that style? Changing to italic title capitalization seems acceptable where all caps were used in place of italics in a title, but what about names?

Q. I am writing a report for a corporate client describing his construction project. When not using the formal name of the project, he insists that I refer to it as “the Project,” where the word “Project” is capitalized. That does not bother me. But when an adjective precedes the word “project,” it strikes me as odd to maintain the capitalization. For example, “this redevelopment Project.” Does Chicago have a recommendation about capitalization in these two instances?

Q. In the sentence “Cane Ridge post office in Van Buren County, Tennessee, was opened in March 1866,” the town name is Cane Ridge and it has a post office. Would you capitalize “Post Office” or leave it lowercase?

Q. Hi, Chicago! My team has a question about kinship names. We understand words like Mom, Dad, and Grandma get capped when standing in place of a name, but we often see son and sis lowercased, even in direct address (e.g., “Well, son, let me explain” and “What’s the matter, sis?”). Is it because those are more terms of endearment than actual stand-ins for the name? Or should Son and Sis be capitalized too?

Q. I have always thought that the only time one uses capitalization after a semicolon is when it is followed by a proper noun (or a word like I). As a mathematics editor, I’ve encountered capitalization after a semicolon with two different publishers (“No; Possible answer: they can find . . .”).  I’ve searched for an answer in CMS but no luck.

Q. How does Chicago style handle capitalization of add-on questions such as the following? “May I have a cookie? two cookies? four cookies?” Should the latter two questions start with a lowercase letter?

Q. Regarding the update to 6.42 about capitalizing a direct question midsentence: Does it apply to a sentence like this? “With all of X’s resources, why [lowercase w] had her cell phone not been fixed?” This type of sentence seems different to me than the examples given in 6.42, but I can’t explain why. Does the new rule apply? Should it be “With all of X’s resources, Why [uppercase W] had her cell phone not been fixed”?

Q. What does it mean when the name of a person is presented in all caps?
