Noun Review

Before you can fully understand what a plural possessive noun is, you'll need a refresher on what a noun is, what a plural noun is and what a possessive noun is.

Nouns: Subject vs. Object

A noun is a person, place, thing, or idea. In English, nouns are most often used as the subject of a sentence (which does the action) and/or the object (which receives the action).

Example sentence - The cat chased the dog around the house last night.

The noun "cat" is the subject (the thing doing the chasing) and the noun "dog" is the object (the thing being chased).

Singular vs. Plural Nouns

Nouns are either singular or plural, depending on whether there is one or many of the thing(s) in question. Cat is a singular noun. Cats is a plural noun.

  • Most singular nouns can be made into plural nouns by adding -s or -es to the end of the word.
  • However, some terms are irregular plural nouns, which means that they don't follow that general rule (such as children being the plural of child).

Possessive Nouns

Nouns sometimes need to be written in a way that shows ownership, which requires knowing how to use the possessive case. This typically requires adding an apostrophe followed by an "s" to the end of a word.

There are many examples of possessive nouns, including singular and plural versions. Plural possessives are more complex than singular possessives because most plural nouns already have an "s" at the end.

What Is a Plural Possessive Noun?

After that quick review, it's time to focus specifically on plural possessive nouns. A plural possessive noun is exactly what it sounds like: a plural noun with a possessive ending to show ownership.

Example sentence - We got our cats' beds from the store.

Here, the noun "cats'" is neither the subject (which is "we") nor the object (which is "beds"). Instead, "cats'" is a plural possessive noun, showing that the object of the sentence belongs to one particular group. The beds belong to the cats. There is more than one cat and there are multiple beds. That's the fundamental idea.

How to Construct a Plural Possessive Noun

There are certain basic rules for constructing possessive nouns. These rules are fairly consistent, though there are always a few (or more) exceptions to the rules in English grammar.

Plurals That End in S

Most English plurals end in "s." If that's the case, to make the plural noun possessive, simply add an apostrophe after the "s." Going back to the cats' beds, the singular noun is cat and its plural form is cats. The plural possessive form is cats'. Consider a few more examples.

  • dogs' treats - treats belonging to dogs
  • stores' management - management of multiple stores
  • executives' decision - a decision made by multiple executives, such as the executive team

Irregular Plurals Not Ending in S

Words with irregular plurals that don't end in "s" are made possessive as if they were singular; that is, by adding an apostrophe followed by an "s."

Example sentence - There was a line to the men's room at the children's choral concert.

Both men and children are plural nouns. Since they don't end in "s," their plural forms are men's and children's. Other examples include:

  • sheep's wool - wool on multiple sheep (sheep can be singular or plural)
  • people's will - will of the people (people is the plural of person)
  • fungi's origin - origin of fungi (fungi is the plural of fungus)

Hyphenated and Compound Nouns

To make a hyphenated or compound noun plural, you'll have to make a few changes. Generally, adding an -s or -es to the first word in the phrase will make it plural. To make it possessive, you'll need to add an apostrophe followed by an "s" to the last word, or just an apostrophe if the last word already ends in "s." For example, if you have had more than one father-in-law and they've all had bad attitudes, you could say "my fathers-in-law's attitudes."

  • governors-general's policies - policies of multiple governors-general
  • passers-by's voices - voices of multiple people who are passing by
  • editors-in-chief's legacies - legacies of multiple editors-in-chief

Two or More Nouns Together

When referencing two or more nouns that are acting together, then the plural possessive form requires adding an apostrophe followed by an "s" to only the last noun. For example, Mary and Kelley are college roommates who share a dorm room. You'd say Mary and Kelley's room to refer to their place of residence. They're acting together because the room belongs to both of them.

  • Jack and Jill's hill - a hill that belongs to Jack and Jill
  • George, Jerry and Elaine's relationship - the relationship among George, Jerry and Elaine
  • Mom and Dad's house - house belonging to Mom and Dad

Multiple Nouns With Different Ownership

When you have two or more nouns together, but they have different ownership, each noun will need an apostrophe and "s" added to the end and the objects will need to be plural. If Rachael and Nathan jointly own two houses, you'd say Rachael and Nathan's houses. But, if Rachael owns her house and Nathan owns his, you'd say Rachael's and Nathan's houses.

  • Jan's and Tony's cars - Jan and Tony own two separate cars
  • George's and Harriet's grades - George and Harriet receive separate grades
  • Matilda's, Yvette's, and Marianne's ambitions - Matilda, Yvette, and Marianne each have different ambitions

Proper Nouns That End in S

When a proper noun already ends in an "s," you have a choice. You can make it possessive simply by adding an apostrophe after the last letter. Or, you can add an apostrophe followed by an "s." When you specify multiple nouns, such as Jessica and Chris, you are already referring to more than one person. To specify that something belongs to both of them, such as their wedding, you could either write Jessica and Chris's wedding. Alternately, you could use "Jessica and Chris' wedding."

  • the Wells and Stephens' vacation - a joint vacation of the Wells and Stephens families
  • Sally and Lucas's engagement - the engagement of Sally and Lucas
  • Carlos' and Nicholas' term papers - one term paper that belongs to Carlos and one that belongs to Nicholas

Types of Nouns

There are several different types of nouns, though they all consistently follow the plural possessive rules described above. There are different ways to categorize them, and many nouns will fit into several categories. For example, the noun "dog" fits into the common, countable and concrete noun categories.

  • Concrete nouns refer to things that can be perceived through the senses. The vast majority of nouns are concrete: bricks, trees, unicycles, zeppelins.
  • Abstract nouns refer to things that cannot be perceived directly by the senses. Examples include liberty, peace and thought.
  • Collective nouns represent a group of things or people. Since the noun refers to the group as a single whole, it's generally treated as singular. Of course, if there's more than one group, it takes the plural form. Examples include family, class, faculty, and society.
  • Common nouns are your run-of-the-mill nouns. Everyday things go in this group, which includes thins like cat, moon, daisy, boys, forest, and power.
  • Countable and uncountable nouns are pretty easy to figure out. Countable nouns can be counted, like books, trees, miles, girls, and buildings. Uncountable nouns are things that can't be counted, like glory, honor or horror.
  • Proper nouns are names referring to a specific person, place, thing, or idea. They are always capitalized. These include Kentucky, Arianna, and The Great Gatsby.
