Bus’s or Buses’?

Possessive forms in English can be a tricky terrain to navigate, especially when it comes to determining whether to use ‘s or just an apostrophe () for singular nouns ending in s. The debate between bus’ and bus’s is a common source of confusion for many English learners and even native speakers. In this article, we’ll delve into the rules governing possessives in English and provide clear examples to elucidate their usage.

Understanding the Basics of Possessives

Before diving into the specifics of bus’ versus bus’s, it’s essential to grasp the fundamentals of possessive forms in English.

In English grammar, a possessive is a grammatical construction used to indicate a relationship of possession or ownership between two entities. It typically involves adding an apostrophe (‘), sometimes followed by an s, to the noun that possesses something.

For singular nouns, the general rule is to add ‘s to the noun, regardless of whether it ends in s. However, there are exceptions and special cases, particularly when it comes to proper nouns, plurals, and words ending in s.

The Dilemma: Bus’ or Bus’s?

When it comes to the possessive form of the word bus, confusion arises because it ends with the letter s. Should it be bus’ or bus’s? The answer lies in understanding the context and adhering to the rules of English grammar.

Singular Nouns Ending in S: Adding ‘s

In standard English usage, singular nouns, including those ending in s, typically take ‘s to form the possessive. Therefore, the correct form would be bus’s.

Example 1: The bus’s engine roared to life as it embarked on its journey through the city streets.

In this sentence, bus’s indicates that the engine belongs to the bus, and the possessive form is formed by adding ‘s to the singular noun bus.

Exceptions: Singular Nouns Ending in Unpronounced S

However, there are exceptions to this rule. If adding an extra s sound after the apostrophe makes pronunciation awkward or unclear, it’s acceptable to use just an apostrophe ().

Example 2: James’ seat on the bus was by the window, offering him a view of the passing scenery.

Here, the possessive form James’ is used because adding another s after the apostrophe would result in an awkward pronunciation (James’s).

Plural Nouns and Proper Nouns: The Role of the Apostrophe

Plural nouns and most proper nouns (names) already end with an s sound. In these cases, only an apostrophe () is added to indicate possession.

Example 3: The buses’ arrival was delayed due to heavy traffic.

In this sentence, buses’ indicates that the arrival is possessed by multiple buses. Since buses is already plural, only the apostrophe is added to form the possessive.

Example 4: Chris’ backpack was left on the bus.

Here, Chris’ denotes possession by Chris. Since Chris is a proper noun, only the apostrophe is added to form the possessive.

Scenario Examples for Possessive Uses

To further illustrate the usage of possessives, let’s consider various scenarios involving the word bus and its possessive forms.

Possession by a Singular Bus

The bus’s windshield wipers squeaked as it navigated through the rain.

In this scenario, the possessive form bus’s indicates that the windshield wipers belong to a single bus.

Possession by Multiple Buses

The buses’ routes overlapped in the downtown area.

Here, buses’ denotes possession by multiple buses, indicating that the routes belong to more than one bus.

Possession by Individuals on the Bus

Maria’s bag was on the bus, but she accidentally left it behind.

In this case, bus is used without a possessive form, as the focus is on Maria’s possession (her bag) rather than the possession of the bus itself.

The children’s chatter filled the bus, creating a lively atmosphere.

Here, bus is again used without a possessive form, emphasizing the atmosphere created by the children rather than possession by the bus.


Navigating the intricacies of possessive forms in English, especially when it comes to nouns ending in s, can be challenging. However, by understanding the rules and applying them in context, one can use possessives accurately and effectively in writing and conversation.

Remember, for singular nouns like bus, the general rule is to add ‘s to form the possessive (bus’s). Exceptions arise when pronunciation becomes awkward, as in the case of proper nouns or plural nouns already ending in an s sound. In such instances, using just an apostrophe () is acceptable.

By paying attention to these rules and practicing their application, writers and speakers can convey ownership and relationships clearly and concisely in English communication. So, the next time you encounter the dilemma of bus’ or bus’s, rest assured that you now have the knowledge to make the right choice.
