Quick Answer

Use “buses.” It is the standard plural of “bus” in American English and British English. Every major dictionary lists it.

“Busses” is a rare variant. Some American dictionaries list it as a second choice. Most editors and teachers mark it as a mistake or an old style.

Here are simple examples:

• Three buses were late this morning. (Correct)
• The city bought ten new electric buses. (Correct)
• Three busses were late this morning. (Rare. Avoid it.)

There is one twist. “Busses” is also the plural of “buss,” an old word for a kiss. And the verb forms “bussed” and “bussing” show up in some places. We cover those below.

Short rule: one bus, two buses.

The Origin of Buses and Busses

The word “bus” is short for “omnibus.” “Omnibus” comes from Latin. It means “for all.” In the early 1800s, horse-drawn carriages in France and England carried many people for a small fee. People called them omnibuses. Soon they just said “bus.”

Now think about how English makes plurals. Most words add -s. Words that end in -s, -x, -z, -ch, or -sh add -es. That is why we say:

• bus → buses
• box → boxes
• church → churches
• gas → gases

So “buses” follows the normal rule.

Why does “busses” exist then? English has another spelling habit. When a short word ends in one vowel and one consonant, writers often double the last letter before endings like -ed or -ing. Think of “run → running” and “stop → stopped.” Some writers applied this habit to “bus.” That gave us “bussed” and “bussing.” Some people then carried the double s into the plural, too.

The word “buss” (a kiss) also has a real double s. This adds to the mix. Over time, “busses” stuck around as a minor spelling, mostly in the US.

British English vs American English Spelling

Good news: for the plural, there is almost no split. Both sides prefer “buses.” The small differences show up in the verb forms and in older or special uses.

Form	American English	British English	Notes
Plural noun	buses (preferred), busses (rare variant)	buses	Same word in both.
Verb, past tense	bused or bussed	bussed (more common)	Both forms seen in US.
Verb, -ing form	busing or bussing	bussing	Common in school transport talk in the US.
Kiss (noun)	buss / busses	buss / busses	Old and rare.
Restaurant worker	busser	rarely used	A US job title.

Simple spelling rule: the plural follows the “add -es” rule. The verb follows the “double the letter” habit. They are two different patterns, so they look different.

Dictionary check: American dictionaries list “buses” first and “busses” second. British dictionaries list “buses.” When two forms exist, the first one is the safe choice.

Which Spelling Should You Use?

Here is advice for each type of reader.

If your audience is in the US: Use “buses.” It is correct and common. You may see “busses” in old texts, but do not copy it.

If your audience is in the UK, Australia, Canada, India, or other Commonwealth countries: Use “buses.” It is the standard form there.

If your audience is global: Use “buses.” It works everywhere and no reader will doubt it.

If you are writing about the verb: Pick one style and stay with it. In the US, “bused/busing” and “bussed/bussing” are both seen. In the UK, “bussed/bussing” is more common. Check your style guide if you have one.

If you are writing about kisses or old texts: “Busses” is correct as the plural of “buss.” This is rare.

Bottom line: for the vehicle, always write “buses.”
