Busses or Buses: Which Spelling Is Correct?

Busses or buses? Both spellings exist in English, but buses is the standard plural of bus when talking about vehicles that carry people.

The word busses is also a real word, but it is a rare spelling of the plural of buss, an old word for a kiss.

This makes the two spellings easy to mix up. Many people are unsure whether to add one s or two when writing about public transport, school trips, or travel.

In this guide, you will learn the correct spelling, the difference between both words, and how to use them in everyday writing.

Quick Answer

Buses is the correct and most common plural of bus when you mean vehicles.

Busses is a rare plural of buss, which means a kiss. It may also appear as a verb form of buss, meaning to kiss.

Examples:

Correct: The buses arrive every morning.
Incorrect for standard vehicle usage: The busses arrive every morning.
Rare usage: The old poem described a pair of busses, meaning kisses.

For everyday writing, use buses whenever you are talking about two or more vehicles.

The Origin of Busses or Buses

The word bus comes from the Latin word omnibus, meaning “for all.” The term became linked to public transport in the 19th century. Over time, omnibus was shortened to bus, and the word became common for vehicles that carry passengers.

The usual plural form is buses. English often adds -es to words ending in s, x, z, ch, or sh to make them plural. For example, class becomes classes, and box becomes boxes.

The word buss has a different history. It is an old English word for a kiss. Its plural can be written as busses, although this use is now uncommon.

The two words have different meanings and histories. That is why buses is the standard choice for vehicles, while busses is mainly seen in older writing or rare uses related to kissing.
