I know how confusing this spelling can feel you see both buses and busses, and suddenly you’re not sure which one belongs in your sentence. From my experience with English usage, the answer is simpler than it looks: one spelling is the standard choice for the plural of bus. So, if you’re searching for the correct form, you’ll find a clear answer here without the usual confusion.
Which is correct: buses or busses?
Buses is the standard plural of bus in modern English. Busses is generally considered a less common variant and may have other uses.
Quick Answer
Buses is the usual and preferred spelling for the plural of bus, meaning more than one passenger vehicle. Busses is also a legitimate plural spelling of bus, but it is much less common and may look like a spelling mistake to many readers. In addition, busses can be the plural of buss, an uncommon word meaning a kiss.
So, if you are writing about public transportation, school transportation, or several vehicles, buses is the safest choice.
Quick Comparison Table
| Form | Main Use | Example |
| buses | Usual plural of bus | Several buses stopped outside the school. |
| busses | Less common plural of bus; also plural of buss | The dictionary lists busses as a variant plural of bus. |
For ordinary modern writing, buses is overwhelmingly the more common choice. Merriam-Webster lists buses first and busses as a variant plural.
What Does “Buses” Mean?
Buses is the standard, everyday plural form of bus. A bus is a large vehicle designed to carry passengers, usually along a particular route or according to a schedule.
For example:
- The buses arrive every 20 minutes.
- We waited for the buses outside the station.
- The school added three new buses this year.
- Several city buses were delayed by traffic.
The word buses can also be the third-person singular present form of the verb bus.
For example:
The company buses employees to the office every morning.
Here, buses is a verb, not a plural noun. It means transports people by bus. Dictionaries also recognize buses as a verb form.
What Does “Busses” Mean?
Busses has more than one possible use, which is why simply calling it “wrong” would be inaccurate.
First, busses can be a less common plural form of bus:
The city purchased several new busses.
This spelling is accepted by major dictionaries, but it is considerably less common than buses. Merriam-Webster specifically notes that the plural busses exists but is now rare.
Second, busses can be the plural of buss, an uncommon noun meaning a kiss.
For example:
The old poem describes several affectionate busses.
In modern everyday English, however, most readers encountering busses in a transportation context will understand that the writer means buses.
Buses vs Busses: Key Difference
The main difference is frequency and context, not a completely different spelling rule.
When you mean several passenger vehicles, use:
buses
This is the normal spelling in contemporary English.
Busses can also refer to several buses, but this form is uncommon. Merriam-Webster records both forms, while noting that buses has become the overwhelming choice of writers and editors.
There is another important distinction:
- bus → buses = several passenger vehicles
- buss → busses = several kisses
The second meaning is uncommon, but it is a real English word.

Common Mistakes
Mistake 1: Using “Busses” Automatically
❌ The busses leave at six every morning.
✅ The buses leave at six every morning.
Why: Busses exists as a variant, but buses is the normal plural spelling.
Mistake 2: Assuming “Busses” Is Always Wrong
❌ “Busses” is never a real English word.
✅ “Busses” is a recognized variant plural of bus and is also the plural of buss.
Why: Calling it completely incorrect ignores legitimate dictionary usage.
Mistake 3: Confusing “Bus” With “Buss”
❌ The poem describes two buses as kisses.
✅ The poem describes two busses as kisses.
Why: Buss is a separate word meaning a kiss.
Mistake 4: Using “Busses” in a Formal Report Without a Reason
❌ The transportation report lists 150 busses.
✅ The transportation report lists 150 buses.
Why: Although the first form can be found in dictionaries, buses is more conventional and clearer in modern formal writing.
Mistake 5: Thinking the Double “S” Must Be Required
❌ A word ending in a short vowel sound must always double its final consonant before -es.
✅ English spelling does not apply that doubling pattern uniformly to bus.
Why: Bus is an established exception to the pattern many learners expect from words such as kiss → kisses.
Mistake 6: Confusing the Noun and Verb
❌ The company buses arrived at the depot.
✅ The company buses arrived at the depot.
In this sentence, buses is a plural noun.
But:
The company buses employees to the depot.
Here, buses is a verb.
The spelling is identical, but the grammatical role changes according to context.
Why Do People Get This Wrong?
The confusion comes largely from English spelling patterns.
Many words ending in -ss form plurals with -es, such as class → classes and bus sounds similar to those words. It therefore feels natural to write busses.
There is also a historical reason for the uncertainty. Buses and busses competed as plural forms when bus became established in English. Merriam-Webster notes that busses was once its preferred dictionary form until 1961, but buses had already become more common and eventually became the dominant spelling.
So the double-s spelling is not simply a random modern mistake. It has a history, but buses is now the overwhelmingly preferred form.
Can Both Forms Be Correct?
Yes, for the Plural of “Bus”
Both buses and busses can function as plural forms of bus.
The city operates several buses.
The city operates several busses.
The first sentence uses the standard and much more common form. The second uses the recognized but uncommon variant.
“Busses” Can Also Have a Different Meaning
There is a separate word, buss, meaning a kiss.
Its plural is:
busses
So:
They exchanged several busses.
Here, busses does not mean buses at all. It means kisses.
This is one reason context matters when you encounter the spelling.
British vs American English
Is “Buses” British or American?
Buses is used in both British and American English.
It is not a spelling that belongs exclusively to one variety.
Is “Busses” British or American?
Busses can also occur in both varieties as a variant plural, but it is much less common than buses.
The important point is that this is not primarily a British-versus-American spelling difference for the noun. The usual plural is buses in both varieties.
There can be more noticeable regional variation in the verb forms, however. For example, some varieties use doubled forms such as bussed and bussing, while American usage commonly uses bused and busing. Merriam-Webster recognizes both sets of verb forms.
Pronunciation
The plural buses is pronounced with an extra syllable:
bus-es
The same basic pronunciation applies to busses when it is the plural of bus.
If busses is the plural of buss, it is likewise pronounced as two syllables.
The spelling therefore does not create a major pronunciation difference between the two plural forms.
Word Origin and History
The modern word bus is a shortened form of omnibus, a word associated with transportation for everyone. Merriam-Webster records the transportation noun bus from the 1830s.
The spelling competition between buses and busses is partly a consequence of how English handles words ending in s. Both forms appeared historically, but buses gradually became much more common. Merriam-Webster notes that busses was the preferred form in its dictionaries until 1961, while buses had become the dominant choice by then.
Simple Memory Trick
Think:
One bus → two buses.
For everyday transportation, simply remember:
BUS + ES = BUSES
If you see busses, pause and ask whether the writer means the uncommon plural of bus or the plural of buss, meaning “kiss.”
