Is it Parent's, Parents', or Parents (Correct Grammar + Examples)

Is it “parents” or “parent’s” or “parents’?” Understanding possessive form and plural nouns is very challenging. For example, it is my parents’ anniversary. This is a grammatically correct sentence in the English language. Although, at first glance, our intuition would tell us that we would want to say “my parent’s anniversary.” That would be incorrect because a person has two parents that both have possession of the anniversary. And “parent’s” is the singular possessive form.

Why is there confusion between parent’s, parents’, and parents?

Words that end in “-s” can get confusing to pluralize. They have a few possessive forms they can take in the English language. For example, a “parent” is one parent. While “parents” is correct when the sentence is, “I have two parents.” Although, when you need “a parent’s signature,” for example, the possessive form changes.

“Parents” definition

Let’s take a look at the definition of the base form:

Word	Definition
Parents (noun) /ˈperənt/	a father or mother.

Here is a simple breakdown of which word form is correct. For examples of each word form in an English sentence, scroll down to the next section.

Word	Correct or incorrect

Parent’s	Correct: Only when using it in the singular possessive form of the word “parent.” For example, “I need your parent’s fingerprints to complete this.”

Parents’, parent’s, and parents sentence examples

Below are sentence examples using the word form correctly:

Can we go to your parents’ house tomorrow for dinner?
How can we get your parent’s signatures for the field trip?
Is it your parents’ anniversary tomorrow?
My parent’s will be leaving tomorrow for their trip.

How to remember which word form to use

Remember that when referring to the singular possessive form, it is similar to saying, “My parent’s.” And when you are referring to things that your parent’s will have to do (an action, a task, a responsibility), use the plural possessive form of the word. For example, “My parents’ house.” Remember this sentence because it is an easy way to show possession and ownership of the two people (the parent’s).

How to use the apostrophe correctly

The possessive singular noun is made by adding an apostrophe and the letter “s” to the singular noun in question, regardless of whether the singular noun ends in an “s” letter.

When a plural noun has an “s” at the end, the possessive form of the noun is created by simply adding an apostrophe. When the noun ends in any other letter, the possessive form is made by adding both an apostrophe and an “s.”

Form	Example
Singular noun	Sarah’s
Plural noun	Women’s
2 or more people	Kim and Adam’s
Singular noun ending in “s”	James’s and James’
Plural noun ending in “s”	Parent’s
2+ people	Kim’s and Adam’s

Apostrophe for Possessives	Apostrophe for Contractions
Amy’s swim class	they + have = they’ve
Karen’s car	are + not = aren’t
Robert’s vehicle	they + will = they’ll

Singular Noun	Plural Noun
My child’s dog	My children’s dog
The man’s work	The men’s work
The mouses’ cage	The mice’s cage
A person’s clothes	People’s clothes
