Have you ever worried about whether you’re using an apostrophe the right way? You’re not alone! The apostrophe may seem tiny, but it can make a big difference in your writing. When you use it correctly, you show readers you care about clarity and professionalism.

Let’s explore the most common uses of the apostrophe and how you can master them.

What is an Apostrophe?

An apostrophe (’) is a punctuation mark that shows possession or takes the place of missing letters in contractions. We use apostrophes to show possession and to form contractions.

Showing Possession

You add an apostrophe to nouns (people, places, things) to show possession.

Singular Nouns

You add ’s to show that something belongs to a single person or thing.

♦ Example: “The cat’s toy” tells us that the toy belongs to the cat.

If a singular noun ends in “s” and you find it awkward to pronounce another “s,” you can just add an apostrophe. This is a style choice.

♦ Example: Moses’ hat instead of Moses’s hat

Plural Nouns

When a word is already plural (ends in s), you put the apostrophe after the s.

♦ Example: “The students’ desks” means the desks belong to the students.

If the plural ends in “s”, you usually add an apostrophe only.

♦ Example: The dogs’ toys, the houses’ roofs

Irregular Plural Nouns

Some plural nouns don’t end in s (like children). In these cases, add ’s just like you do for singular nouns.

♦ Example: “The children’s books” means the books belong to the children.

Possessive Pronouns

However, do not use an apostrophe with possessive pronouns like “yours,” “theirs,” “hers,” “ours,” or “its.”

♦ Correct Example: The dog’s collar (the collar belongs to the dog).
♦ Correct Example: That book is hers (no apostrophe needed for hers).
♦ Incorrect Example: That book is her’s (this is wrong).

Forming Contractions

You also use apostrophes to show that letters are left out when you have combined words (a contraction).

Contractions

Contractions like don’t (do not), won’t (will not), can’t (cannot).

♦ Example: “I’m” is short for “I am.”
♦ Example: “Don’t” is short for “do not.”

Contractions can sound more casual, so avoid them in very formal writing. However, they’re fine in most everyday writing situations.

Dialect Spelling

We also use them in dialect spelling to mimic speech.

♦ Example: That’s ’ow ’tis (instead of “That is how it is”).

Tip: Sometimes you see a thin space before an apostrophe in poetry or older writing to distinguish between a possessive ending and a contraction:

♦ Example: “Where death’s abroad and sorrow’s close behind.”

But this isn’t common in everyday writing, so don’t worry about it unless you’re quoting older texts.

Common Uses of the Apostrophe

Let’s look at some everyday uses of the apostrophe.

Abbreviating Dates

You might see an apostrophe when abbreviating years, but it’s not generally recommended.

♦ Example: The class of ’23 (instead of 2023).

It’s usually clearer to write the full year in formal writing.

Plural of Letters and Numbers

Use an apostrophe only to form the plural of letters or numbers when it helps readability.

♦ Example: Cross your t’s and dot your i’s.
♦ Example: Write your 3’s and 5’s carefully.
♦ Example: My little sister got straight A’s on her report card.

But avoid using the apostrophe just to form a plural in normal words:

♥ Wrong: All the Collins’s were there.
♥ Right: All the Collinses were there.

It’s vs. Its

You often see “it’s” and “its” used incorrectly. Here’s a simple way to keep them straight:

It’s means “it is.” So if you can replace “it’s” with “it is,” you’re using the correct form.

♦ Example: “It’s going to rain today” → “It is going to rain today.”

Its shows possession (something belongs to “it”).

♦ Example: “The dog wagged its tail.” The tail belongs to the dog.

Common Mistakes

What common mistakes do people make with the apostrophe?

Adding Apostrophes to Plurals

Many writers incorrectly add ’s to make a plural, but you only add an apostrophe if you’re showing ownership or a contraction.

♥  Correct: I have two apples.
♥  Incorrect: I have two apple’s.

Forgetting Apostrophes in Contractions

If you skip the apostrophe, your sentence might confuse readers. Always check your words carefully: “can t” or “can’t?”

One of the best ways to catch these errors is to proofread your writing. You can also use grammar tools to help you spot mistakes, but always double-check them since no tool is perfect.

Punctuation Exercises

Punctuate the following sentences with apostrophes.

1. The dogs bone is under the table.
2. My parents cars are parked outside.

Key Takeaways

1. Use “’s” to show possession for singular nouns. Use “’” (apostrophe alone) for plural nouns ending in “s.”
2. Never use an apostrophe with possessive pronouns like “yours,” “hers,” “its,” and “theirs.”
3. Watch out for confusing “it’s” (it is) with “its” (belonging to it).
4. Use apostrophes for contractions (don’t, can’t, haven’t).
5. Form the plural of letters and numbers with apostrophes only for clarity (t’s, i’s, 3’s).

Last Words on the Apostrophe

Pay attention to possession, contractions, and those tricky words like “it’s” and “its.” Books like The Elements of Style or The Chicago Manual of Style can help you confirm the right use of apostrophes.
