Get Exercise For Possessive Nouns

The singular is class, and the plural is classes. The singular possessive is class's (as addressed here).

Possessive pronouns show that something belongs to someone. The possessive pronouns are my, our, your, his, her, its, and their. There's also an independent form of each of these pronouns: mine, ours, yours, his, hers, its, and theirs. Possessive pronouns are never spelled with apostrophes.

When you have an ordinary noun like student, you can tell whether the possessive form refers to one student or many students by looking at where the apostrophe is. When you're talking about one student, add apostrophe + s: The student's favorite subject was science.

So, the possessive form of students (a plural noun that already ends with an -s) is students'.

To form the possessive, add apostrophe + s to the noun. If the noun is plural, or already ends in s, just add an apostrophe after the s.

The general rule is that the possessive of a singular noun is formed by adding an apostrophe and s, whether the singular noun ends in s or not. The possessive of a plural noun is formed by adding only an apostrophe when the noun ends in s, and by adding both an apostrophe and s when it ends in a letter other than s.

I have been invited to the boss's house for dinner. The trainer flipped a fish into the walrus's open mouth. Plural nouns ending in an s simply take an apostrophe at the end to form a possessive noun.

The possessive form is used with nouns referring to people, groups of people, countries, and animals. It shows a relationship of belonging between one thing and another. To form the possessive, add apostrophe + s to the noun. If the noun is plural, or already ends in s, just add an apostrophe after the s.
