The English language is full of quirks, and one common confusion is the plural form of “bus.” Should it be buses or busses? Many English learners—and even native speakers—find themselves second-guessing this choice. This article will break down the correct plural form, explain why one is preferred over the other, and explore the history of the word “bus.”


Understanding Pluralization in English

Before we dive into the specifics of “bus,” it’s important to understand pluralization rules in English.

Standard Rules of Pluralization

Most English nouns follow standard rules when forming their plural:

  • If a noun ends in a vowel + “y,” add -s (e.g., toy → toys).
  • If a noun ends in a consonant + “y,” change “y” to “i” and add -es (e.g., baby → babies).
  • If a noun ends in “s,” “sh,” “ch,” “x,” or “z,” add -es (e.g., box → boxes).
  • Some nouns have irregular plurals (e.g., child → children, man → men).

Since “bus” ends in “s,” one might assume its plural should be busses by adding “-es.” However, that isn’t the case. Let’s explore why.

The Correct Plural of “Bus”

The correct plural of “bus” in modern English is buses.

Why is “Buses” Correct?

  • According to standard spelling conventions, nouns ending in “s” generally add -es for pluralization. However, “bus” is an exception to this rule.
  • “Buses” follows the pattern of similar words like “gas” (gases) and “lens” (lenses).
  • Linguists and grammarians agree that “buses” is the preferred form in standard English.
  • It is the most commonly used plural form in public transportation, education, and official documents.

Why Do Some People Say “Busses”?

The word busses does exist, but it means something completely different. “Busses” is the plural of “buss,” which means “kiss.” This is an outdated term, but it still appears in historical contexts or poetry.

If you write “busses” instead of “buses,” you might accidentally be talking about multiple kisses instead of public transportation vehicles!


A Look at “Bus” and Its History

The word bus is actually a shortened form of “omnibus,” a Latin word meaning “for all.” The first public transportation vehicles were called “omnibuses” in the early 19th century. Over time, the word was shortened to “bus.”
