How To Put Apostrophe

by

Understanding how to put an apostrophe correctly is an essential part of mastering written English. Apostrophes are often small and simple marks, but when used incorrectly, they can cause confusion or alter the meaning of a sentence. Whether you’re dealing with contractions, showing possession, or distinguishing between similar-looking words, knowing where and how to place an apostrophe can improve your grammar and clarity. This guide will walk through the rules and usage examples to help you put apostrophes in the right places with confidence.

Basic Functions of the Apostrophe

1. Showing Possession

One of the main uses of the apostrophe is to show ownership or possession. When something belongs to someone or something else, the apostrophe helps indicate that relationship.

  • Singular NounsAdd apostrophe + s (‘s)
    • The dog’s leash (the leash belongs to the dog)
    • Maria’s book (the book belongs to Maria)
  • Plural Nouns Ending in s”Add only the apostrophe (‘)
    • The teachers’ lounge (the lounge used by the teachers)
    • The players’ uniforms (uniforms that belong to the players)
  • Plural Nouns Not Ending in “s”Add apostrophe + s (‘s)
    • The children’s toys
    • The women’s restroom

2. Creating Contractions

Apostrophes are also used to form contractions, where two words are combined and shortened. The apostrophe replaces the omitted letters.

  • do not → don’t
  • is not → isn’t
  • she is → she’s
  • they are → they’re
  • I would → I’d

Using apostrophes in contractions makes writing sound more natural and conversational, especially in informal settings.

3. Indicating Plural of Letters, Numbers, or Symbols

In specific cases, apostrophes are used to clarify plural forms of single letters or symbols, especially to avoid confusion.

  • Mind your p’s and q’s.
  • There are three s’s in the word possessiveness.
  • Dot your i’s and cross your t’s.

Note It is no longer common to use apostrophes for decades or abbreviations (e.g., 1980s not 1980’s), unless needed for clarity.

Common Apostrophe Mistakes

Its vs. It’s

This is one of the most frequent apostrophe errors.

  • It’sis a contraction of it is or it has.
  • Itsis a possessive pronoun meaning belonging to it.

Examples

  • It’s going to rain. (It is going to rain.)
  • The cat licked its paw. (The paw belongs to the cat.)

Your vs. You’re

  • You’reis a contraction of you are.
  • Youris a possessive pronoun.

Examples

  • You’re my best friend. (You are my best friend.)
  • Your phone is ringing. (The phone belongs to you.)

Their vs. They’re vs. There

  • They’re= they are
  • Their= belonging to them
  • There= refers to a place or situation

Examples

  • They’re coming over at 6 p.m.
  • Their house is across the street.
  • Let’s meet over there.

Where Not to Use Apostrophes

1. Plural Nouns

Never use apostrophes to make regular nouns plural.

  • Incorrect Apple’s for sale
  • Correct Apples for sale

2. Possessive Pronouns

Possessive pronouns (his, hers, ours, yours, its, theirs) never take apostrophes.

  • Incorrect The dog wagged it’s tail.
  • Correct The dog wagged its tail.

3. Verb Forms

Don’t use apostrophes in verb forms ending in s.

  • Incorrect She run’s every morning.
  • Correct She runs every morning.

Advanced Apostrophe Use in Writing

Compound Possession

When two people own something jointly, add the apostrophe only to the second name.

  • John and Mary’s car (they share one car)

When each person owns something separately, add apostrophes to both names.

  • John’s and Mary’s cars (each has their own car)

Business Names

Some businesses drop apostrophes from their names even when grammatically required.

  • Correct grammar McDonald’s
  • Brand choice Starbucks (not possessive)

Follow the company’s chosen spelling, even if it goes against grammar rules.

Tips for Using Apostrophes Correctly

  • Always ask Is this showing ownership or shortening a word?
  • Read the sentence aloud does it’s make sense as it is?
  • When in doubt, test the contraction by expanding it.
  • Don’t rely on autocorrect it doesn’t always know the grammar rule.
