This question already has an answer here:

I've recently caught myself spending too much time wondering about several off-sounding compounds I've come across, e.g. browsers list (as in, a list of browsers) and tasks queue (as in, a queue of tasks).

I can't help it, but pluralizing the first word sounds weird to me. I would have said, "browser list" and "task queue".

Which grammatical number is proper grammar?

(This question is quite similar, but isn't answered with regards to this specific detail.)

    I don't think "browsers list" is valid. A "browser list" is a list, each member of which is a "browser". A "browsers list" is a list, each member of which is a "browsers" :) just as an "egg box" is a box each member of which is an egg, while an "eggs box" is a box each member of which is an "eggs". – fundagain Nov 14 '18 at 8:12

Although the phrase means the same thing in either case, the singular and the plural mean entirely different things and are therefore both correct and grammatical.

"Browsers list" refers to a list of individual elements each of which is a "browser".

"Browser list" refers to a list in the class "browser," that is, elements belonging to the class.

Generally though, since we are referring to members of a class and all of them belong to the same class, we use the reference to class, i.e., the singular.

User IDs: various elements, all of the type User ID (reference to class).
Users IDs or Users' IDs: IDs of several users. (no reference to class).

  • Thanks; though, I don't quite understand the notion of "class" that you're using, so both list definitions sound relatively interchangeable to me. Could you help clarifying the difference even more? – Chiru Nov 14 '18 at 7:49

    Thanks again. Does "Users IDs or Users' IDs" not rather imply "IDs of several users, all of the type User ID" and thus reference the class/type as well? – Chiru Nov 14 '18 at 7:53

    @Kris Are you sure you are correct here? What is an "eggs box" and why? Can you give a reference for your answer. – fundagain Nov 14 '18 at 8:13

    @Kris I don't get it. If someone comes to my shop and asks for an "eggs box", what should I sell them. I only have "egg boxes" in the store room. Do I sell them one of those? – fundagain Nov 14 '18 at 8:37

    Google ngrams knows of no "eggs box". books.google.com/ngrams/… – fundagain Nov 14 '18 at 9:26
