Usage and Grammar

Q. Is it okay to use “Latinx” instead of “Latino” or “Latina”?

Q. When is “lay” or “lie” used?

Q. Which is the correct form when informally captioning a photo: “Lenny and me at the store” or “Lenny and I at the store”? I always use the former, reasoning that you would not caption a photo “I at the store,” but many people have “corrected” me.

Q. Hi there! In my research I often use the phrase “Israeli-based company,” and colleagues always push back, suggesting that “Israel-based company” sounds more correct. I’ve found references suggesting I’m right but would love confirmation (or correction!) from the good folks at Chicago. Many thanks.

Q. In running text, should “at” be included before an Instagram or Twitter handle? For example, “To learn more, tweet her @username” or “To learn more, tweet her at @username”?

Q. This sentence has a dual subject but the author has a singular verb, which sounds right to the ear but can’t be correct, right? Here is the sentence: “Building and extending sewer systems requires large capital investments.” Should it read “require” to match the “building and extending” or can those two things be somehow considered as a single thing? Thank you!

Q. I am editing a brief in which the author has used “and/or” multiple times. I know that this term should be avoided, but I’m not exactly sure why. Is it because it’s confusing and ambiguous? What is The Chicago Manual of Style’s stance?

Q. Would you use “less” or “fewer” with “CO₂ emissions”? To me, “emissions” seems like a measurable, uncountable substance, so I would say “less.” However, a quick search on Google Ngrams shows “fewer emissions” is more common. Which is correct? Or should it be “lower” instead? And if so, why?

Q. Hello. Is it appropriate to use ’s for “is”? For example: John’s running every day.

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”?
