Busses or Buses: Grammar Guide 2026

When writing about public transport, you may pause and wonder: is it “busses” or “buses”? Both spellings have appeared in English, but they do not have the same level of acceptance today. For most writers, the correct and standard plural of bus is buses.

This small spelling question can cause trouble in schoolwork, emails, websites, business writing, and social media posts. 

The confusion often comes from English spelling rules. Words that end in -s, -sh, -ch, or -x often take -es in the plural, so “buses” follows a familiar pattern. 

Yet “busses” can also be found in dictionaries and older texts because it has had a different use and history.

This guide explains busses or buses in simple terms. You will learn which spelling is standard, where each form comes from, how British and American English treat it, common mistakes, and how the words appear in everyday writing. 

You will also see examples and practical advice for choosing the right spelling.

Busses or Buses – Quick Answer

Buses is the standard and most common plural of bus.

• One bus
• Two buses
• Several buses
• The buses are late.

Busses is a less common spelling. It can appear as a plural of bus, but modern standard writing normally uses buses.

There is also another word, busses, which can be the third-person singular form of the verb buss, meaning “to kiss.”

Examples:

The city added 20 new buses.

The school buses arrive at 7:30 a.m.

She busses her children on the cheek.

For normal public transportation, choose buses.

The Origin of Busses or Buses

The word bus comes from omnibus, a Latin word meaning “for all.” The shortened form bus became common in English as a word for a large passenger vehicle.

English plural spelling developed over time. Since bus ends in s, writers needed to decide how to form its plural.

The spelling buses follows the common English pattern of adding -es to words ending in an s sound:

• bus > buses
• class > classes
• glass > glasses
• dress > dresses

The spelling busses has also been used historically. It follows a pattern seen in some words where a final consonant is doubled before adding an ending.

Today, however, buses is overwhelmingly the normal spelling for more than one bus.

The spelling busses still has a separate use. The verb buss means to kiss. Therefore, busses can mean “kisses” or “kisses someone,” depending on the sentence.
