Have you ever been confused about when to use “Sundays” or “Sunday’s”? You’re not alone! In this guide, we’ll explore the differences between singular, plural, and possessive forms, focusing on the word “Sunday”.

Our goal is to make this as simple as possible, like explaining it to a third grader. So, let’s dive in and clear up the confusion!

What are Singular, Plural, and Possessive Forms?

What are Singular, Plural, and Possessive Forms

Before we tackle our main topic, let’s understand some basic terms:

  • Singular: This means just one. If you have one apple, you’d say, “This is my apple.”
  • Plural: This means more than one. If you have two or more apples, you’d say, “These are my apples.”
  • Possessive: This shows ownership. If the apple belongs to Bob, you’d say, “This is Bob’s apple.”

Sundays, Sunday’s, or Sundays’?

To make it easy, let’s look at a table that explains the difference between these forms when we talk about our favorite day of the week, Sunday.

FormExplanationExample Sentence
SundaysPlural: More than one Sunday.“I love Sundays because I get to rest.”
Sunday’sSingular Possessive: Something that belongs to or is related to one Sunday.“Sunday’s weather was perfect for a picnic.”
Sundays’Plural Possessive: Rarely used, but it would mean something belonging to multiple Sundays.“The Sundays’ charm is in their relaxing pace.”

When to Use Each Form

1. Sundays (Plural)

Use “Sundays” when you are talking about more than one Sunday. It’s as simple as adding an “s” to make something plural.

  • Example: “Sundays are my favorite days to sleep in.”

2. Sunday’s (Singular Possessive)

Use “Sunday’s” when something belongs to or is associated with a specific Sunday. Here, you add an apostrophe followed by an “s” to show possession.

  • Example: “Sunday’s schedule is packed with fun activities.”

3. Sundays’ (Plural Possessive)

This form is not commonly used because it’s rare to talk about things belonging to many Sundays at once. However, if you ever need to, you would place an apostrophe after the “s” in “Sundays”.

  • Hypothetical Example: “The Sundays’ vibes are always relaxing.” (Note: This is a creative example to illustrate how the form might be used, but such usage is unusual.)

Practice Makes Perfect

Now that you know the difference, here’s a little quiz. Choose the correct form for each sentence:

  • “I always do my laundry on ________.” (Sundays/Sunday’s)
  • “_______ morning sunshine is the best!” (Sundays/Sunday’s)
  • “The ________ quietness is something I cherish.” (Sundays’/Sunday’s)


  • Sundays
  • Sunday’s
  • Sundays’ (Though rare and a bit forced, it’s grammatically correct in this creative use.)


Understanding when to use “Sundays,” “Sunday’s,” and “Sundays’” is important for clear communication. Remember, “Sundays” refers to more than one Sunday, “Sunday’s” shows something belongs to a specific Sunday, and “Sundays’” would imply possession over multiple Sundays. With a bit of practice, you’ll master these in no time. Now, go enjoy your Sundays (or Sunday’s delights) with confidence in your grammar skills!
