Busses vs. Buses: Meaning, Spelling, and Correct Usage

Busses vs buses has a simple practical answer: use buses when referring to more than one bus. It is the standard plural for passenger vehicles, including school buses, city buses, and tour buses. This spelling is preferred in both American English and British English.

Although busses is accepted as a rare spelling variant, many readers may view it as an error. However, it can also be the plural of buss, an old-fashioned word meaning kiss.

Knowing the words’ meanings, grammar roles, and usage context helps you choose the right spelling. You’ll also avoid common mistakes involving bused, bussed, busing, bussing, and the possessive form bus’s.

Quick Answer: Is It Buses or Busses?

Use buses when referring to more than one bus:

• The city added six electric buses.
• Three school buses arrived late.
• Modern computers use internal buses to transfer data.

Busses is sometimes accepted as an alternative plural of bus. Still, it’s rare in modern writing. Most editors, teachers, and readers expect buses.

The spelling busses is clearer when it comes from buss, meaning a kiss:

• The grandmother gave the children several affectionate busses.
• He busses his daughter on the cheek before leaving.

Here is the easiest rule to remember:

When you mean passenger vehicles or computer pathways, write buses.

Busses vs. Buses at a Glance

Word	Base word	Grammar role	Main meaning	Modern usage
bus	bus	Singular noun	One passenger vehicle or one data pathway	Standard
buses	bus	Plural noun	More than one vehicle or data pathway	Standard and preferred
buses	bus	Present-tense verb	Transports people or clears tables	Standard

Both spellings can exist, but they don’t have equal status in everyday writing. Buses is almost always the right choice when the base word is bus.

What Does “Buses” Mean?

The word buses can function as a plural noun or a verb. Its exact meaning depends on the sentence.

Buses as the Plural of Bus

A bus is a large vehicle designed to carry several passengers. Its standard plural is buses.

• One bus is waiting outside.
• Four buses are waiting outside.

The plural appears in many common transportation terms:

• School buses
• City buses
• Public buses
• Tour buses
• Shuttle buses
• Airport buses
• Electric buses
• Intercity buses
• Charter buses
• Double-decker buses

For example:

• The district bought five new school buses.
• Free shuttle buses run between the airport terminals.
• Many US cities are replacing diesel buses with electric models.
• Our tour group traveled in two separate buses.

In each sentence, buses refers to multiple passenger vehicles. This is the spelling you should use in casual, formal, academic, and professional writing.

Buses as a Present-Tense Verb

Buses can also be a verb. It is the third-person singular form of bus in the simple present tense.

Subject	Verb form
I	bus
You	bus
We	bus
They	bus
He, she, it	buses

As a verb, bus commonly has two meanings in American English.

First, it can mean to transport people by bus:

• The school buses students from rural neighborhoods.
• The hotel buses guests to the convention center.
• The company buses workers between its two campuses.

Second, it can mean to remove used dishes from a restaurant table:

• Maya buses tables during the dinner shift.
• The server takes orders while an assistant buses the tables.
• He buses each table as soon as the customers leave.

The surrounding words usually make the intended meaning clear. Students are bused to school, while dishes are bused from tables.

Buses in Computing and Electronics

In computing, a bus is a communication pathway that carries data, addresses, or control signals between components. The standard plural is buses.

Common technical terms include:

• Data bus
• Address bus
• Control bus
• System bus
• Memory bus
• Expansion bus
• Serial bus

For example:

• The processor communicates with other components through several buses.
• Data buses carry information between parts of a computer.
• The system uses separate address and data buses.
• Engineers tested both communication buses for signal errors.

This technical meaning is different from public transportation. Nevertheless, it uses the same singular and plural forms: bus and buses.

What Does “Busses” Mean?

The spelling busses has two possible explanations. It may be an uncommon plural of bus, or it may come from the separate word buss.

Busses as a Variant Plural of Bus

Some established dictionaries list busses as a variant plural of bus. Therefore, a sentence such as the following isn’t necessarily ungrammatical:

• Several busses stopped outside the stadium.

However, buses is the standard modern spelling:

• Several buses stopped outside the stadium.

The second version is clearer and more familiar. It’s also the safer choice for:

• School assignments
• College papers
• News articles
• Business reports
• Transportation schedules
• Government documents
• Professional emails
• Website content
• Technical manuals

A recognized variant isn’t always the best editorial choice. Readers may assume busses is a typo because they encounter it far less often than buses.

Busses as the Plural of Buss

The noun buss means a kiss. Its plural is busses.

• The child received hugs and busses from her relatives.
• The play ended with several comic busses.
• His aunt greeted everyone with cheerful busses on both cheeks.

This use sounds old-fashioned, literary, humorous, or playful in modern American English. Most people would simply use kiss and kisses in ordinary conversation.

Still, busses is correctly spelled when it is the plural of the noun buss.

Busses as a Verb Meaning Kisses

Buss can also be a verb meaning to kiss. Therefore, busses is its third-person singular form.

• She busses the baby on the forehead.
• The actor busses his costar’s hand during the scene.
• He busses his wife on the cheek before work.

Again, this usage is uncommon today. You’re more likely to encounter it in older books, historical dialogue, humorous writing, or deliberately playful prose.

The Key Difference Between Busses and Buses

The main difference involves standard usage and meaning.

Buses is the preferred plural of bus. It also works as a verb for transporting passengers or clearing restaurant tables. In addition, it is the plural used for computer and electronic buses.

Busses, by contrast, is a less common variant plural of bus. It can also come from buss, meaning a kiss.

Intended meaning	Recommended word	Example
Multiple passenger vehicles	buses	The buses leave at noon.
Multiple school vehicles	buses	Both buses serve the same school.
Computer pathways	buses	The buses transfer data.
Transports by bus	buses	The hotel buses its guests downtown.
Clears restaurant tables	buses	Alex buses tables after school.
Multiple kisses	busses	She gave the children several busses.
Kisses someone	busses	He busses her cheek.
Variant spelling for vehicles	busses	Accepted by some dictionaries, but buses is preferred.

If you’re writing about transportation, buses will almost always communicate your meaning more effectively.

Why Is the Plural Usually Spelled “Buses”?

English often forms the plural of a noun ending in -s by adding -es:

• class → classes
• gas → gases
• lens → lenses
• plus → pluses
• bus → buses

The result is buses, not buss. The additional syllable also makes the plural easier to pronounce.

However, writers sometimes expect the final consonant to double because bus has a short vowel sound. That expectation produces busses.

English consonant doubling doesn’t follow one simple rule in every situation. Doubling often occurs before certain suffixes, especially when a stressed final syllable ends in one vowel and one consonant:

• run → running
• begin → beginning
• admit → admitted

However, forming a noun’s plural isn’t the same process as adding -ing or -ed to a verb. You shouldn’t automatically apply the consonant-doubling rule to every plural noun.

For modern standard usage, remember this direct pattern:

One bus, two buses.

The Spelling History of Bus and Buses

The word bus developed as a shortened form of omnibus. An omnibus was a public vehicle that carried many passengers. Over time, speakers shortened the longer word to bus.

Because bus was an unusual shortened form, its plural spelling varied. Writers used both buses and busses, and dictionaries recorded both forms.

Eventually, buses became the dominant spelling. Today, busses remains in some dictionaries as a variant, but recognition doesn’t mean equal frequency or preference.

This history explains why you may find busses in older texts. It may reflect the spelling convention of the period rather than an error.

When discussing historical writing, preserve the author’s original spelling in a quotation. In your own modern prose, however, use buses for the plural of bus.

How to Pronounce Buses and Busses

When both spellings refer to vehicles, buses and busses are generally pronounced the same way. They have two syllables.

A simple pronunciation guide is:

• bus: “buhs”
• buses: “BUH-siz”

The plural ending sounds like -iz, not simply -s:

• bus + es → bus-es
• class + es → class-es
• kiss + es → kiss-es

Because the two spellings sound alike, pronunciation won’t help you choose between them. You must consider the word’s meaning and standard spelling.

The noun buss, meaning a kiss, is also pronounced like bus. Consequently, busses meaning kisses sounds like buses meaning vehicles. Context separates the meanings.

Compare:

• The buses waited outside the school.
• Her affectionate busses embarrassed the children.

The first sentence involves transportation. The second involves kisses.

Is “Busses” Incorrect?

Busses isn’t always incorrect. Its accuracy depends on what you mean and which spelling convention you follow.

It is correct in these situations:

• As the plural of buss, meaning more than one kiss
• As a verb meaning kisses
• As a dictionary-recognized, though uncommon, variant plural of bus

Still, accepted usage and recommended usage aren’t always identical. An editor may replace busses with buses in a transportation article because the standard form is easier to recognize.

Consider these versions:

• Accepted variant: The city operates 200 busses.
• Standard and preferred: The city operates 200 buses.

The first sentence may be defensible, but it can distract readers. The second communicates the same fact without raising a spelling question.

Therefore, buses is the better choice when clarity matters.

American English vs. British English Usage

A common misconception claims that buses is American English while busses is British English. That distinction isn’t accurate.

Buses is the usual plural in both American English and British English. You’ll see it in transportation notices, newspapers, school materials, government publications, and everyday writing on both sides of the Atlantic.

Variety of English	Standard plural
American English	buses
British English	buses
Canadian English	buses
Australian English	buses

The spelling busses may appear in different regions, but it isn’t the standard British alternative to American buses.

This issue differs from true regional spelling contrasts, such as:

• color in American English; colour in British English
• traveled in American English; travelled often in British English
• center in American English; centre in British English

For bus, regional spelling doesn’t create the same clear split. Use buses in both major varieties.

Correct and Incorrect Examples Explained

Sentence	Judgment	Explanation
The school buses arrived at 7:30.	Correct	Buses is the standard vehicle plural.
The school bus’s arrived at 7:30.	Incorrect	An apostrophe doesn’t form a regular plural.
The school busses arrived at 7:30.	Accepted variant, not preferred	Some dictionaries recognize it, but buses is standard.
The company buses workers downtown.	Correct	Buses is a present-tense verb.
The restaurant buses its tables quickly.	Grammatically possible but awkward	People bus dishes or clear tables, rather than transport the tables themselves.

Singular, Plural, and Possessive Forms

Writers sometimes confuse buses, bus’s, and buses’. These forms perform different jobs.

Form	Meaning	Example
bus	One vehicle	The bus is late.
buses	More than one vehicle	The buses are late.
bus’s	Something belonging to one bus	The bus’s door is stuck.
buses’	Something belonging to multiple buses	The buses’ routes overlap.

An apostrophe shows possession. It doesn’t create the regular plural.

Incorrect:

• Three bus’s arrived together.

Correct:

• Three buses arrived together.

For one bus, add apostrophe plus s:

• The bus’s engine needs repair.

For several buses, place the apostrophe after the plural s:

• The buses’ departure times changed.

Verb Forms of Bus

The verb bus has more than one recorded spelling pattern. In modern writing, bused and busing are widely used. The doubled forms bussed and bussing also appear.

Verb form	Common spelling	Variant
Base form	bus	—
Third-person singular	buses	busses
Past tense	bused	bussed
Past participle	bused	bussed
Present participle	busing	bussing

Examples include:

• The district buses students every morning.
• Students were bused to another campus.
• The city is busing passengers around the closed station.
• He is bussing tables tonight.

The doubled spelling bussing is especially familiar in restaurant contexts. However, house styles and dictionaries may differ on preferred verb forms. Whichever form you choose, remain consistent within the same document.

Don’t confuse these forms with the verb buss, meaning to kiss. Context usually prevents misunderstanding.

Common Mistakes to Avoid

Writing “Bus’s” as a Plural

An apostrophe doesn’t make bus plural.

Incorrect:

• Five bus’s serve this route.

Correct:

• Five buses serve this route.

Use bus’s only when something belongs to one bus:

• The bus’s windshield was cracked.

Assuming the Final S Must Be Doubled

Some writers choose busses because they expect English to double the final consonant. However, the standard plural is buses.

Use:

• one bus
• two buses
• several buses

Treating the Spellings as a US–UK Difference

Both American and British writers normally use buses. Therefore, don’t switch to busses simply because your audience is British.

Using a Singular Verb with Buses

Because buses is plural when it refers to vehicles, it normally takes a plural verb.

Incorrect:

• The buses is outside.

Correct:

• The buses are outside.

However, when buses is itself a verb, the noun before it is singular:

• The hotel buses its guests to the airport.

Using “Busses” Without Considering Its Other Meaning

A sentence about “several busses” may briefly suggest kisses rather than vehicles. Although context will usually resolve the meaning, buses avoids the distraction.

Switching Spellings in One Document

Don’t write buses in one paragraph and busses in the next when both refer to vehicles. Choose one form and use it consistently. In almost every modern document, that form should be buses.

Real-Life Usage Cases

A School Announcement

Suppose an administrator writes:

• All busses will leave at 3:15 p.m.

The meaning is understandable, but parents may notice the unusual spelling. A clearer announcement would read:

• All buses will leave at 3:15 p.m.

Because public notices should be instantly clear, the standard spelling is the stronger choice.

A Restaurant Job Description

A manager writes:

• The employee greets guests and buses tables.

Here, buses is a verb. Still, some restaurants may use busses or busses tables, while many prefer buses tables or the clearer phrase clears tables.

For a broad audience, this version avoids any uncertainty:

• The employee greets guests and clears used dishes from tables.

A Computer Science Assignment

A student writes:

• The processor uses separate address and data busses.

Some technical readers may accept the spelling. However, buses is the standard plural in modern computing:

• The processor uses separate address and data buses.

A Historical Novel

An author writes:

• Aunt Margaret welcomed him with three hearty busses.

In this setting, busses means kisses. The old-fashioned word may suit the historical voice, so changing it to buses would destroy the intended meaning.

A Simple Decision Guide

Use these steps whenever you’re unsure:

1. Are you referring to multiple passenger vehicles?
   Write buses.
2. Are you discussing computer or electronic pathways?
   Write buses.
3. Does the verb mean transporting people?
   Use buses in the present tense.
4. Does the verb mean clearing restaurant dishes?
   Buses is standard, although doubled verb forms also appear.
5. Does the word mean kisses?
   Use busses, though kisses may sound more natural.
6. Did you find “busses” in older writing?
   It may be a historical variant rather than an error.
7. Are you writing for school or work?
   Choose buses for maximum clarity.

Memory Tricks for Buses and Busses

A useful memory trick should be simple enough to recall while writing.

Try this pattern:

One bus takes us; two buses take us.

Both buses and uses have one s before the -es ending.

You can also connect the doubled spelling to its less common meaning:

A buss is a kiss, so busses can mean kisses.

Finally, remember the most practical rule:

• Vehicles → buses
• Computer pathways → buses
• Kisses → busses
