Have you ever stood at a bus stop, looked around, and wondered, “What’s the plural of bus? Is it buses or busses?” You’re not alone! English can sometimes feel tricky, especially with words that don’t follow simple patterns. But don’t worry we’re going to break this down step by step in a friendly and easy-to-follow way.

By the end of this guide, you’ll know exactly how to use the plural of bus correctly, why it’s spelled the way it is, and you’ll even see fun examples to help the word stick in your memory. So, let’s take a ride together and learn about bus and its plural form!
Possessive Forms and Verb Agreement
Once you know that buses is the plural, one more pair of forms is worth learning: the possessives. The singular possessive is bus’s, as in “the bus’s door was open.” The plural possessive is buses’, as in “the buses’ schedule changed.” Notice that the plural possessive just adds an apostrophe after the final s, with no extra letter.
Verbs need to match their subject too. A singular subject takes a singular verb, and a plural subject takes a plural verb: “The bus is late,” but “The buses are late.” A very common slip is writing “the buses is” — always pair buses with are, were, or have, and you’ll sound perfectly natural.
Frequently Asked Questions
What is the plural of bus?
The plural of bus is buses. Because the word ends in an “s” sound, we add -es instead of just -s. This is the standard, dictionary-recognized spelling used in everyday English.
Is “busses” a real word?
“Busses” is a real word, but it is normally a verb form, not a plural noun — for example, “she busses tables at the restaurant.” As a plural of the vehicle, “busses” only appears in very old writing. For the plural noun, always write buses.
Do I say “the buses is” or “the buses are”?
Say “the buses are.” Since “buses” is plural, it needs a plural verb — this is called subject-verb agreement. So: “The bus is late,” but “The buses are late.”
What other words follow the same plural rule as bus?
Words ending in s, sh, ch, x, or z add -es: glass → glasses, dish → dishes, watch → watches, box → boxes. A handy memory trick: if the word ends in a hissing sound, give it the extra “e.”
What Is the Plural of Bus?
The simple answer: the plural of bus is buses — the one correct plural form recognized by dictionaries like Merriam-Webster.
Yes, that’s it! Most of the time, when you want to talk about more than one bus, you just add -es at the end:
- 1 bus → 2 buses
- The bus is late → The buses are late
Pretty straightforward, right? But then why do some people also write busses? Let’s dig a little deeper.
Why Do We Add “-es” Instead of Just “-s”?
Here’s where English spelling rules come in. When a word ends with s, sh, ch, x, or z, we usually add -es to make it plural.
For example:
- class → classes
- box → boxes
- brush → brushes
Since bus ends with an “s” sound, it follows the same rule: bus → buses.
This rule makes the word easier to say. Imagine if we just added “s” and got buss. That would look strange and be hard to pronounce. Adding “-es” solves the problem and keeps the word clear.
But What About “Busses”?
Here’s where confusion often happens with these confusable words. You may see the word busses sometimes, but it doesn’t usually mean more than one bus.
- Busses can actually mean something else: it’s an old-fashioned or alternative spelling of the word kisses or caresses.
- For example, “She gave him many busses on the cheek.”
In modern English, we almost never use busses for this meaning anymore. Today, buses is the standard plural of bus.
So if you’re talking about vehicles, always stick with buses as your preferred plural.
Is Bus Singular or Plural?
This one’s simple in terms of singular vs plural: bus is singular and buses is plural.
- Singular: “The bus is waiting at the stop.”
- Plural: “Three buses are waiting at the stop.”
Think of it just like other words:
- cat → cats
- dog → dogs
- bus → buses
Easy, right?
Where Does the Word “Bus” Come From?
Let’s pause for a fun fact! Did you know that bus is actually short for a longer word?
The word comes from omnibus, a Latin word that means “for everyone.” In the 19th century, when large vehicles were first used to carry many passengers, they were called “omnibuses.” Over time, people shortened it to just “bus.”
So when you step onto a bus, you’re literally stepping onto a vehicle meant “for everyone.”
Examples of Bus and Buses in Sentences
To really understand the plural of bus, let’s look at some practical examples. These sentences show how you might use the word in everyday conversation.
- “The school bus picks up children every morning.” (singular)
- “Two school buses were waiting outside the school.” (plural)
- “I missed the last bus home last night.” (singular)
- “During the strike, all city buses stopped running.” (plural)
- “That red bus looks brand new.” (singular)
- “Tourists filled the double-decker buses in London.” (plural)
Notice how natural buses sounds in each of these example sentences.

Comparing Bus With Other Similar Words
To make things even clearer, let’s compare bus with a few other words that follow the same pattern:
- Glass → glasses
- Dress → dresses
- Guess → guesses
Just like these words, bus needs that extra “e” before the “s” when we make it plural.
Now imagine if you said glasses as glasss that would look and sound odd. The same logic applies to bus.
