Q. If one refers to the DeVos (pronounced DeVOSS) family members in the plural, would they be the DeVoses or the DeVosses? If the former, that would appear to be pronounced “DeVOSEes” rather than “DeVOSSES,” as would be correct.

Q. My question refers to the plural use of acronyms and initialisms. As I have always understood it, the acronym or initialism can be pluralized only if the last letter indicates the plural item. So MOU (memorandum/memoranda of understanding) cannot become MOUs, but ICT can become ICTs (information and communication technologies). I run into this problem a lot with the initialism RFP (request for proposals), which people like to pluralize as RFPs to indicate multiple requests. The word proposals is already plural, so it does not make sense to me to add an s to the end of the initialism. What is the correct way to make acronyms or initialisms plural?

Q. CMOS 7.12 says, “If an italicized term such as the title of a newspaper or book or a word used as a word must be written in the plural, the s is normally set in roman. A title already in plural form, however, may be left unchanged.” The example given is “four New York Times.” If the CMOS considers the name of that newspaper to be plural, that suggests it would find this sentence acceptable: “The New York Times are the paper of record.”

Q. I am making a plaque which reads “Happy Holidays.” Underneath is a picture of a sled. Underneath that is “The Simmons.” Their last name is Simmons (with an s). How should it read on the plaque? The Simmons’, The Simmons’s, or just The Simmons? Thank you.

Q. What is the correct ending (singular or plural) to this sentence? This moving, musical journey inspires “drummers” of all ages to follow the beat in their heart. Is it hearts? Is it beats and hearts? Is it just beat and heart? This is driving me insane! Please help!

Q. The plural of curriculum is curricula. Why does the dictionary list symposiums as an acceptable plural for symposium? And does the rule differ for every plural of words ending in -um?

Q. When using the plural of “ad,” i.e., “ad’s,” is it incorrect to use the apostrophe? The three-letter string “ads” just looks so wrong when typesetting it. Would appreciate your guidance.

Q. When I was working on my graduate degree in English, I was told by a professor that the rule had changed for plurals of numbers (written as numbers) and letters (3s rather than 3’s or As rather than A’s). For the past 15 years I have been teaching it that way. Another colleague just recently saw that rule change somewhere online. Our new textbooks, however, do not teach it that way. We are currently working on a new handbook and would like to know if the rule has been changed or not. Thanks.

Q. Since the late 1980s, when I got my first copy of CMOS, I have understood that verbs associated with a noun used to group plural items should correspond with the singular, grouping noun. For example, “A growing number of reports has revealed . . .” Microsoft Word, however, keeps indicating a grammatical error when I follow this rule and was placated when I changed “has” to “have” in the above example. Can you please clarify who is right? Is it I or the copyeditors consulted by Bill Gates?

Q. I am wondering if you could clarify the proper usage associated with names of sports teams and other such organizations where the name does not clearly end in a plural form. I offer as examples the NBA’s Miami Heat and Orlando Magic or the NHL’s Tampa Bay Lightning. I think the names ought to be considered plural—for example, “The Tampa Bay Lightning have won five of their last six games against the Washington Capitals.” On page D1 of the Washington Post from November 15, 2003, in contrast, a story began with the following sentence: “The Miami Heat seemed to do everything it could to hand Friday night’s game to Washington.” . . . Perhaps the best solution is just to use the city name in such cases.
