Q. Does “plus” function like “and” in making two nouns a plural subject? For example, would you say, “This idea plus others like it are gaining traction” or “is gaining traction”?
A. “Plus,” when it’s not acting as a noun (that’s a plus) or as an adjective (a plus sign), can function as either a preposition or a conjunction. As a preposition, it means “in addition to” and takes a singular verb: five plus six equals eleven. As a conjunction, it means “and” and takes a plural verb: a banana plus a loaf of bread were on the table. If the subjects are being considered collectively, use a singular verb; otherwise, opt for the plural. In your example, the ideas alluded to in the subject are gaining traction individually, so “plus” is conjunctive and “are” is the better choice. If you can keep track of all these distinctions, you get an A plus (where “plus” is functioning as an adjective to modify the letter grade).

Q. Hi. My question has to do with whether a new entry in the 17th edition was accidental or deliberate. Paragraph 8.185 includes this sentence: “ ‘Aladdin’ is arguably the most well-known tale in A Thousand and One Nights.” I’m curious to know if this sentence simply slipped through or if Chicago defends the use of “most well-known”? I ask because Philip Corbett, standards editor for the New York Times, ran a blog called After Deadline as a teaching tool to point out grammatical and stylistic missteps that made it to print. He often called out writers for using “most well-known” in place of “best-known”: “The superlative form of the adverb ‘well’ is ‘best.’ So there’s no reason to describe something as ‘the most well-known’—make it ‘the best-known’ ” (After Deadline, August 4, 2008).
A. For newspapers, especially those that are published in print, concision is crucial, so changing “most well-known” to “best-known” as a matter of policy makes good sense. (Nothing compares to After Deadline for its combination of practical, field-tested advice and journalistic wisdom.) But where space is not at such a premium, is “best-known” necessarily an improvement over “most well-known”?
“Well-known” is an established compound; it’s listed in Merriam-Webster (where it’s defined as “fully or widely known”). The meaning of “well-known” is therefore well known (Chicago drops the hyphen for most compound adjectives after the noun). So “the most well-known author” arguably loses just a little by being changed to “the best-known author.” “Best-known” is OK, but it isn’t in Merriam-Webster.
“Well-known” isn’t the only well-known “well-” compound. Consider “well-rounded”: “best-rounded” isn’t a great alternative for “most well-rounded.” And what about “best-heeled”? Some work better than others, so it’s probably best to consider these on a case-by-case basis. And in the case of “most well-known,” our editors apparently chose to leave well enough alone.

Q. The emigrate/immigrate distinction has been the subject of differing opinions in our office. Each time a case arises, we consult CMOS 5.250 and come up with different interpretations. Editing the following sentence, for example, we changed “immigrate” to “emigrate”: Justice Abella was born in a displaced persons camp in Stuttgart, Germany, and with her family immigrated to Canada in 1950. Several of us argue that it’s “immigrate” because she’s going to Canada; others say “emigrate” because she’s leaving a past home. Please let us know which is correct.
A. In the example you cite, either term is correct. To emphasize Justice Abella’s departure from Germany, choose emigrate; to emphasize the move to Canada, choose immigrate. In the former case, “from Germany” is understood:
Justice Abella was born in a displaced persons camp in Stuttgart, Germany, and with her family emigrated [from Germany] to Canada in 1950.
You could avoid the issue altogether by choosing “migrate,” but that term is more often applied in relation to movement between regions (e.g., south to north) than to specific countries.

Q. Doesn’t “The US is the second-largest carbon dioxide emitter after China” make it sound like the US is actually the third-largest carbon dioxide emitter? I see these formulations, which include [number] plus [superlative] and a direct comparison, often, and they seem confusing. Wouldn’t it make more sense to say “The US is the largest carbon dioxide emitter after China” or “The US is the second-largest carbon dioxide emitter; China is the largest”?
A. You’re right: if you think about it for more than three or four seconds, that sentence is less than perfectly unambiguous. But no one would describe the third-largest emitter as the second-largest emitter after the second-largest emitter! This is an example of a convenient and harmless shorthand—where “after” means something like “trailing only.” And it’s a helpful shorthand: not only is it concise, but it also prevents the momentary ambiguity inherent in your first solution (“The US is the largest carbon dioxide emitter . . .”). Note that a comma, though typically omitted from “nth-largest . . . after . . .” constructions, would provide useful clarification before the prepositional phrase “after China”; before the participial phrase “trailing only China,” such a comma would be required (see CMOS 6.30).

Q. I’m troubled by this sentence: “She combed her hair, brushed her teeth, and was putting on her lipstick when the phone rang.” I think it should be reworded since the list does not have parallel construction. My friend disagrees. Is it correct as is, or is there a simple fix?
A. You are correct. In a series of verb phrases, any auxiliary verb must apply equally to all of the phrases. So that “was”—an auxiliary verb that helps to create the past-progressive tense—is a problem. You can fix it by adding a conjunction to break up the series: “She combed her hair and brushed her teeth and was putting on her lipstick when the phone rang.” CMOS 5.245 covers this issue (minus the lipstick). For more on progressive tenses, see 5.135.

Q. Sometimes I have a hard time distinguishing between a predicate adjective and a past-tense verb being used in a passive-voice construction. For example, in “this dish was leftover,” is “leftover” an adjective, or should it be “was left over,” with “left” being a verb and “over” being an adverb?
A. That’s tricky because “leftover” is both a noun and an adjective. The noun, which is usually plural, would require an article in the singular: a leftover. So the dish was either a leftover (sing. noun) or it was left over (the phrasal verb from which the noun and adjective are derived). Either one will work. It might also be described as a dish of leftovers (pl. noun). But the adjective form really only works before the noun: this leftover dish.

Q. In the following sentence, “Ships arriving in Venice from infected ports were required to sit at anchor for forty days before landing,” is the word “landing” a verb form, or a verbal (gerund)? Why?
A. In your example, “landing” is a gerund—a present participle used as a noun. Note that it’s the object of the preposition “before”; only a noun (or a noun phrase) can be the object of a preposition. You can also compare “landing” to the other present participle in your example, “arriving,” which is used not as a noun but as an adjective: the participial phrase “arriving in Venice from infected ports” modifies the noun “Ships.” So “arriving” is a participle but not a gerund. For more on participles and gerunds, see CMOS 5.110–16.

Q. Is it necessary to continue repeating the auxiliary had after its first instantiation when writing a complex sentence with some of the verbs in the pluperfect: “She had taken many rides in the train and [had] seen many sights, sights that [had] awakened her curiosity, but what [had] most intrigued her . . .”? If not, it seems the reader would have an ambiguous idea about where the event is situated in time.
A. This is a thorny issue, especially for fiction writers. Mignon Fogarty wrote a good post about it at Grammar Girl. The idea is to mix it up a little instead of repeating had a million times. Doing it gracefully and avoiding ambiguity requires some skill, but when it’s done well, readers get the idea.

Q. My proofreader says that the verb needs to be singular in this caption, but that reads as incorrect to me. Can you instruct me or give me bragging rights (not that I would ever brag, of course)? “Ann Smith, one of seven alumni who talks about leadership.”
A. Those seven alumni who talk about leadership are plural, so the verb should be plural as well. Ann Smith will have to get her own verb. (But please be nice to your proofreader!)

Q. Regarding the use of and in a short parenthetical list, here is an example: “channels that confer sensitivity to heat (TrpV1, TrpM2, TrpM3).” My project manager thinks there is a need to place and between the last two items in the parens. I know of no such rule and cannot think of a reason why the word would be necessary (other than the customer is always right). Any insights on this minor dilemma?
A. English isn’t as bossy as a lot of people believe. There’s no rule that a series must include and. When someone makes up a rule, don’t fall for it! Reply, “Ah—I didn’t know that rule! Could you please tell me where I can find it?”
