The Amazing Apostrophe: Embracing Ownership and Omission

Mastering the Art of Apostrophe Use


Apostrophe use for contractions and possessionApostrophes, those small but powerful punctuation marks, play a crucial role in written language. However, their usage is often a source of confusion and frustration for many writers. In this article, we will delve into the intricacies of apostrophe usage, exploring the rules that govern their placement and the possible variations that may occur.

It is important to note that most apostrophe rules are consistent and do not vary, regardless of the style guide, while others may vary based on the specific style or preference of the writer or publication. The key is to remain consistent in your application of apostrophes and follow the relevant style guide where necessary.

Rules for Apostrophe Use



A pivotal role of the apostrophe in English grammar is to facilitate contractions, a linguistic device that involves the merging of two words through the omission of specific letters. This process enhances the efficiency of communication by condensing phrases and making them more succinct without compromising clarity.

Contractions typically involve replacing one or more omitted letters with an apostrophe when combining two words. For instance, the contraction “can’t” originates from “cannot”. Here, the apostrophe takes the place of the omitted letters “no”, resulting in a more streamlined and expedient form of expression.

The utilisation of contractions, facilitated by the apostrophe, is not only a linguistic shortcut but also a stylistic choice. It injects a sense of informality and rhythm into language, fostering a more natural flow. Mastering the use of apostrophes in contractions is essential for effective communication as it allows writers to convey ideas concisely and expressively while adhering to grammatical conventions.



A fundamental application of the apostrophe in the English language is to signify possession. This usage imparts clarity to written and spoken communication, designating ownership or association between a noun and the entity possessing or connected to it.

In possessive forms, the apostrophe typically appears followed by the letter “s” (‘s) after a singular noun, indicating that the person, thing, or concept possesses something. For example, in the phrase “the cat’s toy”, the apostrophe and “s” combination conveys that the toy belongs to the cat.

When dealing with plural nouns that already end in “s”, place the apostrophe after the existing “s” (s’) without adding another “s”. For instance, “the students’ books” illustrates that the books belong collectively to the students.

When two or more individuals share ownership, only add the apostrophe to the last noun. For example, “John and Mary’s house” signifies that John and Mary jointly own the house.

However, when dealing with plural nouns not ending in “s”, the apostrophe precedes the “s” to denote possession. For example, the phrase “the women’s club” indicates that the club is associated with or belongs to the women.

This apostrophic distinction is crucial for expressing ownership relationships, whether it involves individuals, groups, or inanimate objects. Writers ensure the accurate and effective conveyance of their messages by understanding and correctly applying the rules of apostrophe use for possession. This usage not only adds precision to language but also contributes to the overall coherence and professionalism of written communication.

Pluralisation of Letters

Pluralisation of Letters

The apostrophe plays a crucial role in indicating pluralisation, especially when dealing with single letters. While its usage in forming plurals is generally straightforward, there are specific rules that govern the application of the apostrophe when dealing with individual letters.

When forming the plural of a single letter, avoid using the apostrophe. Instead, simply add an “s” at the end. This rule applies uniformly to all letters of the alphabet. For example, if you want to pluralise the letter “A”, you write “As”, and “B” becomes “Bs”. In this context, consider the apostrophe unnecessary and incorrect.

This rule holds true whether you’re dealing with uppercase or lowercase letters. For instance, the plural of “a” is “as” and the plural of “Z” is “Zs”.

It’s important to note that the absence of an apostrophe in the pluralisation of letters is consistent and unchanging across different style guides and linguistic conventions. Whether you are writing formally or informally, the rule remains the same.

Understanding and adhering to this rule is crucial for maintaining grammatical accuracy and clarity in your writing. Whether you discuss grades, label items, or indicate multiple instances of a letter, the English language universally accepts and standardises the practice of omitting an apostrophe in these plural forms.

Pluralisation of Numbers

Pluralisation of Numbers

When it comes to pluralising numbers, the role of the apostrophe is quite distinct. Numbers typically do not involve the use of an apostrophe when forming the plural.

Standard Pluralisation

For most numbers, simply add an “s” to form the plural. For example, 5=5s, 10=10s, and 100=100s.


When referring to a range of years or a decade, it is common to add an “s” without an apostrophe. For example, the 1980s, not the 1980’s.

Years in Abbreviated Form

When expressing a year in an abbreviated form, use the apostrophe at the beginning to denote dropping the first two numbers but don’t use an apostrophe before the “s”. For instance, the ’90s, not the ’90’s.

Possessive Forms of Numbers

When indicating possession with numbers, use an apostrophe and an “s” after the number. For instance, the 1960s’ music (referring to music of the 1960) or 1970’s fashion was unique (referring to fashion in 1970).

Note that the use of an apostrophe in pluralising numbers is primarily employed to indicate possession rather than forming a straightforward plural. This less common usage is typically found in more specific contexts, often related to historical periods or possessions associated with particular numeric values.

Understanding these conventions ensures clarity and correctness in your writing, helping you navigate the nuanced rules surrounding the use of apostrophes with numbers.

Pluralisation of Acronyms

Pluralisation of Acronyms

Pluralising acronyms involves a specific set of rules regarding the use of apostrophes. Unlike common nouns or letters, acronyms generally follow a consistent pattern when forming plurals. It is important to note that apostrophe use in this context may vary according to different style guides.

Standard Pluralisation

Adding an “s” without an apostrophe is the common method for pluralising most acronyms. For example, DVDs, CDs, FAQs.

Acronyms Ending with “S”

Acronyms that end with “s” usually form their plurals by adding “es” without using an apostrophe, as exemplified by “GPSes”.


Possessive Pronouns

Unlike possessive nouns, possessive pronouns inherently convey ownership without the addition of an apostrophe and an “s”. Here are the common possessive pronouns and their forms:

  • The book is mine – it is my book.
  • The car is yours – it is your car.
  • The jacket is his – it is his book.
  • The purse is hers – it is her book.
  • The house has lost its charm.
  • The project is ours – it is our project.
  • The decision is theirs – it is their decision.
