Possessives and Attributives

Q. Good morning! I want to know, should it be “farmers’ market” or “farmers market”? I see everything out there, including “farmer’s market.” Anyway, just a seasonal curiosity for you all!

Q. In reply to the question of whether it should be “the Rangers hockey game” or “the Rangers’ hockey game,” you basically said that both are acceptable but the former is slightly preferred. I’d like to point out two things that make the former even more preferable. (1) The Rangers play more than one hockey game (and more than one per season), so you can never attend the Rangers hockey game, but only a Rangers hockey game. (2) A hockey game isn’t really a possession of the Rangers like their rink, but is rather an event (something incorporeal) that is merely highly associated with the Rangers, and whose association with the Rangers is only 50 percent (the other 50 percent of the association is with the opposing team).

Q. Should the possessive form of Los Angeles include the extra s? As a Spanish term, the city’s name is a singular noun, plural in form, but if we consider it fully anglicized, does it then count as a regular singular? Or does the plural form carry through?

Q. I’m on a team editing kids’ textbooks. One book includes a poster showing shapes (circle, square, triangle). Should this be referred to as a shapes poster? Is it an example of the genitive case 4 (at CMOS 5.20), requiring an apostrophe: shapes’ poster? If not, is it a temporary compound noun? Could it be written either way, based on personal preference? Does genitive case 7 help at all? A poster of shapes = shapes’ poster.

Q. I think there’s a contradiction in your examples of the correct use of apostrophes. CMOS 7.20 states that in the case of a place-name ending with “s,” the “s’s” formation is not used; e.g., the United States’. However, 7.17 uses Kansas’s as an example of proper usage. Is that correct?

Q. When referring to the left or right side of a vehicle, is the adjective possessive or attributive? Is the proper form “driver’s-side door” or “driver-side door”?

Q. This question has probably been asked before, but at work we are updating the human resources manual and nobody seems to know the answer. Is the apostrophe necessary in “two weeks’ notice” and “three days’ sick leave”? We will really appreciate your advice.

Q. For our work editing projects, we have had a long-standing debate over the wording “renters insurance” (as a concept). There seems to be no industry standard with regard to using an apostrophe. Which should it be? Renters’ insurance, renter’s insurance, renters insurance.

Q. When referring to “the corps” as in the Army Corps of Engineers or the Peace Corps, what is the proper possessive form? For example, is it “the corps’ decision” or “the corps’s decision?”

Q. How would this be punctuated correctly? “The AZ Group of Companies’, comprising ABC Machine Company, DEF Machine Company, and GHI Corporation, mission is to provide . . .” or “The AZ Group of Companies,’ comprising ABC Machine Company, DEF Machine Company, and GHI Corporation, mission is to provide . . .”? I’m writing a brochure and can’t find it anywhere online.
