In the first part of this series, we discussed how apostrophes are used with singular nouns and indefinite pronouns. Today, we are going to jump into plural nouns, compound words, and two or more nouns.
For plural nouns not ending in –s, write the appropriate plural spelling of the word then add an apostrophe and –s to form the possessive.
For plural nouns that do end in –s, write the plural spelling of the word then add an apostrophe.
>>Note: Do not use apostrophes to form plural nouns.
I have three books. (correct)
I have three book’s. (incorrect)
She owns two dogs. (correct)
She owns two dog’s. (incorrect)
When forming the possessive of compound words, make only the last word possessive.

Two or More Nouns
For words that show individual possession, each word in the group should be possessive.

For words that show joint possession, only the last word in the group should be possessive.

>>Exception: Make the first word possessive if the second word is a possessive pronoun.
