Have you ever stopped mid-sentence and wondered, “Is it buses or busses?” You’re not alone. English can be a bit quirky, especially when it comes to plurals. Even a simple, everyday word like “bus” can cause some confusion. You’ve likely seen both forms floating around online or in older books. So, which one is correct, and when—if ever—should you use the other?
Understanding the right plural form matters. It shows your attention to detail, strengthens your communication, and builds credibility—whether you’re writing a paper, a blog post, or a sign for a school trip. While the difference might seem small, using the wrong form could cause readers to stop and question your grammar. And let’s be honest, nobody wants that.
This blog post breaks it all down in a simple, easy-to-read format. You’ll learn where the confusion started, what grammar rules apply, how spelling has evolved, and what dictionaries say. We’ll even explore synonyms, common errors, and the etymology behind the word “bus.”
By the end, you’ll know without a doubt when to write “buses” and why “busses” usually gets the red squiggly underline. So buckle up—let’s ride through this topic together!
Understanding the Pluralization Debate
The question of “buses or busses” might seem like a typo issue, but it goes much deeper. It taps into how we understand spelling patterns, language evolution, and grammar rules.
Some people assume “busses” must be right because it follows what seems like a standard English rule—adding -es to a word that ends in s. Others feel it just looks wrong and prefer “buses.” This divide has led to long-running debates on forums, grammar websites, and social media.
To solve the puzzle, we need to look at why both versions exist and how language authorities have settled the debate.
Why Is There Confusion Between “Buses” and “Busses”?
The confusion stems from:
- Spelling rules that apply to similar-looking words
- Different dictionary listings and regional usage
- Historical spellings that were once more common
- Autocorrect inconsistencies between devices and platforms
To make it worse, “busses” is also a real word—but not the one you might think. That adds even more fuel to the confusion. So yes, both spellings exist, but one is right for “bus,” and the other refers to something else entirely.
The Role of Spelling Variants in English
English is known for its flexibility and borrowed roots. That’s why we have multiple spellings for the same word depending on where you are:
- Color (US) vs. Colour (UK)
- Theater vs. Theatre
- Catalog vs. Catalogue
So, is “busses” a British spelling? Not really. Both American and British English overwhelmingly use “buses.”
The idea of “busses” as an alternate regional spelling is mostly a misunderstanding. While it may appear in older British texts, it has fallen out of favor and isn’t used in modern writing.
The Correct Plural Form of “Bus”
Let’s settle this once and for all.
“Buses”: The Standard Accepted Plural
“Buses” is the correct and accepted plural of the word “bus.”
Every major dictionary agrees:
- Merriam-Webster: bus → buses
- Oxford English Dictionary: bus → buses
- Cambridge Dictionary: bus → buses
In schools, news articles, traffic signage, and academic writing, you’ll always see “buses.” It follows the standard grammar rules, which we’ll explain shortly.
“Busses”: Is It Ever Correct?
Strangely, yes—but not for what you think.
“Busses” is a real word, but it has a different meaning: it’s an old-fashioned way to spell “kisses.”
For example:
- “She gave him two quick busses on the cheek.”
In rare poetry or older English literature, you might find this usage. But in modern English, it’s considered outdated and confusing.
So unless you’re talking about multiple kisses in a poem, avoid “busses.”
What Does “Bus” Mean?
To fully understand the plural, we should know what the word actually means—and how it’s used.
Modern Definitions and Uses
“Bus” is short for omnibus, a term meaning “for all” in Latin.
It usually refers to:
- A large motor vehicle used for public transportation
- A tour coach or school bus
- In tech, a data path or communication system in computers
- Informal sayings like “under the bus” or “catch the bus”
So the word has grown from physical transportation to metaphorical and technical uses.
Evolution of the Term “Bus”
Originally coined in the early 1800s in France and England, “omnibus” referred to public carriages for all people. Over time, the term was shortened simply to “bus.”
It became more common with the spread of city transportation systems, especially in the 20th century. Today, we use “bus” across fields—from school commutes to digital communication systems.
Grammar Rules Behind “Buses”
Let’s talk about grammar. English has rules (and many exceptions) for forming plural nouns. Here’s how “bus” fits in.
General Rules for Forming Plurals in English
- Add “-s” to most nouns:
- cat → cats
- book → books
- cat → cats
- Add “-es” to words ending in s, sh, ch, x, or z:
- box → boxes
- dish → dishes
- class → classes
- box → boxes
- Change y to ies if a word ends in consonant + y:
- baby → babies
- baby → babies
- Irregular forms:
- man → men
- child → children
- mouse → mice
- man → men
How “Bus” Fits These Rules
The word “bus” ends in “s”, so we follow rule #2:
bus → buses
That’s it! Adding “-es” is both natural and grammatically correct.
Words with Similar Pluralization Patterns
Here are some common examples that work the same way as “bus”:
- kiss → kisses
- glass → glasses
- pass → passes
- class → classes
Each of these follows the same “add -es” rule due to their ending in s.
Exceptions and Irregular Forms
English is famous for breaking its own rules. However, “bus” isn’t one of those rule-breakers. Its plural is regular and follows a clear rule.
Synonyms and Alternative Terms for “Bus”

- Shuttle – often used for short-distance airport or hotel routes

Conclusion: Which One Should You Use?
Here’s the bottom line—when it comes to the plural of “bus,” the correct and widely accepted form is always “buses.”
If you’re writing about transportation, school pickups, city transit, or even data pathways in technology, “buses” is the only grammatically correct plural. It’s supported by all major dictionaries, taught in schools, and used in professional and casual writing alike.
On the other hand, “buses” are outdated, rare, and confusing. Unless you’re quoting old poetry where it means “kisses,” you should avoid using it. Today, “busses” only appears in niche literary contexts and doesn’t belong in modern usage.
