What is an Apostrophe: Explained with Examples

 

Apostrophes may be small punctuation marks, but they play a powerful role in written English. A single misplaced apostrophe can completely change the meaning of a sentence or make otherwise clear writing look incorrect and unprofessional. From showing possession to forming contractions, apostrophes help convey meaning, clarity, and tone in everyday communication. This blog breaks down what is an apostrophe, how and when to use an apostrophe, some common apostrophe examples, and the most recurring mistakes to avoid. With clear rules, practical examples and online assignment help, you can make apostrophe usage simple, logical, and easy to apply in both academic and everyday writing.

What is an Apostrophe?

In simple terms apostrophe (’) is a grammatical punctuation mark that is widely used in English for two main purposes: to show possession, and represent contractions. Unknowingly, you may have incurred the use of apostrophes many times, and may even have used it in your writings. But without knowing the apostrophe rules, students commonly make errors. So it is important to understand the correct use of apostrophes in different contexts.

Use of Apostrophes in English Grammar

1. Apostrophes for Possession

Possession apostrophes are most commonly used to explain ownership, possession, or belonging.

1.1 Singular Nouns

Rule: add—  ’s

Examples: the student’s book, the teacher’s desk

Here, the apostrophe represents that the book belongs to the student, and the desk belongs to the teacher. 

2. Plural Nouns Ending in “s”

Rule: add ’ after the s

Examples: the students’ classroom, the teachers’ lounge

Note the apostrophe’s usage is after the s. This shows the possession for a collective noun. The classroom belongs to a group of students, and the lounge belongs to a group of teachers.

3. Irregular Plural Nouns

Rule: add ’s

Examples: children’s toys, men’s shoes

For nouns that assume a different form in the plural sense, like child→children, the rule remains the same as for singular nouns, i.e. adding ‘s.

4. Possession With Names

What if a name already ends with the letter ‘s’? When a singular name ends in “s”, there are two accepted styles for showing possession. Both are grammatically correct; the choice depends on the style guide being followed.

Style 1: Add ’s (more common in modern English)

1. James’s book

2. Chris’s laptop

Style 2: Add only ’ (often used in traditional or journalistic writing)

1. James’ book

2. Chris’ laptop

5. Joint Possession

If two people own something together, the apostrophe is added only to the second name.

- Tom and Amy's apartment (they share one apartment)

When they own things separately, each name is given a possessive form with an apostrophe.

- Tom's and Amy's cars (they each have their own car)

All these cases show the possession or belongingness of an object. The other primary use of apostrophe comes within contractions.

- Apostrophes for Omission in Contractions

Contractions are a unique type of word that combines two or more other words in a shortened form, usually with an apostrophe. Here, the omission apostrophe replaces the missing letters in the word. For example:

1. do not → don’t

2. it is → it’s

3. you are → you’re

These are terms that are very commonly used in written and spoken language, but the key here is the apostrophe that is to be used in place of the letter omitted.

Apostrophes in Informal Omissions and Numbers

You may have seen people writing “Class of ‘95” in their profiles. What does that mean? Apostrophes may be used in an informal sense in words and numbers— this is used for the omitted characters. For example:

1. 2020 → ’20

2. Class of 2015 → Class of ’15

3. the 1980s → the ’80s

Similarly for words,

1. going → goin’

2. rock and roll → rock ‘n’ roll

3. because → ’cause

Apostrophes Used for Plurals of Letters

In some cases, apostrophes are used to show the plural of individual letters, especially when writing lowercase letters. This is done mainly to avoid confusion and improve readability.

Examples:

1. Mind your p’s and q’s.

2. She received all A’s in her exam.

3. There are too many i’s in that word.

However, it is important to note that apostrophes are not generally used to form plurals. In modern English, plurals of numbers, abbreviations, and acronyms usually do not require apostrophes. And hence these form the multiple cases where apostrophes are used.

Apostrophes v/s Possessive Pronouns

A common area of confusion in English grammar is knowing when to use an apostrophe and when not to. This is especially true with possessive pronouns, which do not use apostrophes at all, even though they show ownership. Possessive pronouns include: his, hers, its, yours, theirs, whose. These words already indicate possession on their own.

Examples: Use of possessive pronouns, & no apostrophe—

1. This book is hers.

2. The dog wagged its tail.

3. That responsibility is yours.

4. The house is theirs.

In contrast, apostrophes are used with nouns, not possessive pronouns, to show ownership.

Examples: Use of Apostrophe—

1. The girl’s bag is on the table.

2. That is Jake’s notebook.

3. The children’s playground is new.

Common Apostrophe Mistakes to Avoid

1. Make sure you don’t confuse apostrophes with plurals. It is crucial to understand its usage in solidarity and not confuse apostrophes with plural forms that also utilise an ‘s’ in the end. For example, writing apple’s or  book’s is incorrect. It is—apples and books.

2. Don’t confuse possessive pronouns with the use of apostrophes. Words like his, hers, yours, theirs are possessive pronouns that signify belonging without the use of apostrophe. One of the most common mistakes people make is the usage of its v/s it’s. “Its” is the possessive pronoun of the pronoun “it”. It does not contain any apostrophe. Whereas the word "It's” is simply a contraction of “It is” — which does include an apostrophe for the omitted letter i.

3. Using Apostrophes With Verbs. Writing words like “run’s” or “eat’s” is incorrect. Verbs don’t take apostrophes and the s in “runs” simply shows the form of the verb being used.

These rules may seem confusing to understand, and even more difficult to apply in writing grammatically cohesive assignments. This is where Locus Assignments can help you out! Buy your assignment from the Locus Assignments login now!
