buses (BUS-iz)

busses (BUS-iz)

Word	Pronunciation	Meaning
Bus	BUS	One vehicle
Buses	BUS-iz	More than one bus
Busses	BUS-iz	Less common plural of bus

The extra s in busses does not create a different pronunciation.

So, when you hear someone say buses, you cannot tell from the sound which spelling they would use.

The Origin and Background of Buses and Busses

The word bus is a shortened form of omnibus, a Latin word meaning “for all.” The word became associated with public transportation in the 19th century.

As the short form bus became common in English, speakers needed a plural form. Both buses and busses developed as possible spellings.

English has many words that form plurals by adding -es. Because bus already ends in s, writers sometimes choose busses by analogy with words such as glass → glasses.

However, buses became the more common spelling for the plural of bus.

Why Does “Busses” Exist?

English spelling is not always perfectly regular. Different spellings can develop over time, especially when a word ends in a letter that already appears in its plural ending.

Busses follows a pattern that may look natural to some writers.

But modern usage strongly favors buses for the plural of the vehicle bus.

A Small Historical Connection

The word bus is also connected to the French term omnibus, which was used for public passenger vehicles. Over time, English speakers shortened the word to bus.

Today, bus is a normal everyday word used around the world.

Common Mistakes with Busses and Buses

❌ Less Preferred	✅ Preferred

Several busses arrived late.	Several buses arrived late.
School busses are parked outside.	School buses are parked outside.
The new busses are electric.	The new buses are electric.

Mistake 1: Thinking Busses Is Always Wrong

It is not.

Busses is a recognized variant plural of bus. The issue is that it is much less common than buses.

So it is better to say:

Buses = preferred

Busses = acceptable but uncommon

Mistake 2: Adding Only “S”

Some learners write:

bus → buss

This is not the normal plural form.

The standard plural is:

bus → buses

Mistake 3: Confusing Bus With Buss

There is another English word, buss, which can mean a kiss, especially in older or literary English.

Its plural can be busses.

That means busses can sometimes have a completely different meaning from multiple vehicles.

Example:

The old poem mentions several busses.

Depending on context, this could refer to kisses rather than vehicles.

This is another reason context matters.

Mistake 4: Assuming More Letters Mean Better Spelling

English spelling does not always work that way.

Because bus ends in s, adding another s may look logical. But common modern usage favors buses.
