The phrase “Buses or Busses The Correct Plural of Bus” refers to the long-standing confusion over which spelling accurately represents more than one “bus.” While both forms have appeared in written English, “buses” is widely recognized as the grammatically correct plural of “bus” in modern usage. “Busses,” on the other hand, is often mistaken for a variant but is typically associated with an entirely different word meaning “kisses.”
In language, small differences often lead to big misunderstandings. This isn’t just a spelling debate—it’s a matter of clarity, precision, and credibility in writing. Choosing the wrong form can make your sentence look outdated or grammatically incorrect, especially in formal settings like academic writing or professional communication.
Understanding why “buses” is the preferred plural helps improve your grasp of English spelling rules. It also highlights how older, rarely used forms like “busses” have drifted into linguistic obscurity, making “buses” the clear choice for today’s English speakers.
The Definitive Answer: Buses vs. Busses
Let’s cut to the chase: Buses is the standard and correct plural form of bus in modern English. The correct plural of bus is “buses” – with just one ‘s’ after the ‘u’. This is the spelling you’ll find recommended by leading authorities like the Oxford English Dictionary, Merriam-Webster, The Chicago Manual of Style, and the Associated Press Stylebook.
Buses or Busses: The Correct Plural of Bus question can be answered definitively by looking at usage statistics. The spelling “buses” appears in approximately 95% of published works across English-speaking countries, while “busses” represents only about 5% of occurrences.
| Spelling | Usage Percentage | Recommended by Style Guides | Current Standard |
|---|---|---|---|

| Busses | ~5% | No | No |
“The plural of ‘bus’ is ‘buses.’ ‘Busses’ is an outdated form that has largely fallen out of use in contemporary English.” — The Chicago Manual of Style
Why the Confusion Exists
The confusion around whether buses vs busses grammar is correct stems from several factors:
Inconsistent Pluralization Rules
English has notoriously irregular pluralization rules. While most words ending in ‘s’ form plurals by adding ‘es’ (bus → buses), some words follow different patterns:
- Words ending in ‘s’ where we double the ‘s’ before adding ‘es’:
- kiss → kisses
- fuss → fusses
- truss → trusses
- Words ending in ‘s’ where we simply add ‘es’:
- bus → buses
- plus → pluses
- virus → viruses
This inconsistency creates natural confusion when forming the plural of bus.
Historical Usage
Historically, “busses” was more common. The term bus originated as a shortened form of the Latin word “omnibus” (meaning “for all” or “serving all”). When it was first abbreviated to “bus” in the early 19th century, the plural form often appeared as “busses.”
As English spelling conventions evolved through the 20th century, “buses” became the standard spelling, but “busses” lingered in some regions and contexts.
The Verb Confusion
Another source of confusion comes from the verb “to buss,” meaning to kiss. The conjugation of this verb follows the pattern of doubling the ‘s’ before adding suffixes:
- I buss, he busses, they were bussing, etc.
This related but distinct word adds to the grammar confusion over whether to spell buses or busses the correct plural of bus.
The Evolution of “Bus”
The word bus has a fascinating etymology that explains much about its pluralization.
From Omnibus to Bus
The term “bus” first appeared in the 1830s as a shortened form of “omnibus,” which itself came into English from French, though its origin is Latin. An omnibus was a large, enclosed horse-drawn vehicle for public transport.
| Year | Development |
|---|---|
| 1820s | “Omnibus” enters English language |
| 1830s | Shortened to “bus” |
| 1850s | Plural forms “buses” and “busses” both in use |
| 1950s | “Buses” becomes clearly dominant |
| Present | “Buses” is standard in both American and British English |
The Standardization Process
Throughout the 19th and early 20th centuries, both “buses” and “busses” appeared in print. However, as language standardization efforts intensified in the mid-20th century, grammar standards solidified around “buses” as the preferred form.
Several factors contributed to this standardization:
- The trend toward simplification in English spelling
- The influence of major dictionaries and style guides
- The logical parallel with other words like “plus” → “pluses”
By the 1950s, buses had clearly established itself as the dominant form in both American and British English.
Special Cases and Exceptions
While buses is undoubtedly the standard plural form for multiple bus vehicles, there are some special cases worth noting:
Technical Contexts
In computing and electronics, the term “bus” refers to a communication system that transfers data between components. In this context, the plural is also “buses” when referring to multiple data buses, address buses, or control buses.
The computer motherboard contains several buses that connect the CPU to memory and peripherals.
Brand Names and Company Style Guides
Some transportation companies have their own style guides that might deviate from standard usage. For example, a company named “Busses R Us” would use that spelling in its branding regardless of grammatical standards.
Regional Variations
While “buses” dominates globally, some regional English dialects and old vs modern spelling traditions maintain “busses” in colloquial usage, especially in some parts of the United Kingdom and Australia.
Words Following Similar Pluralization Rules
To help remember that buses or busses the correct plural of bus is “buses,” consider these words that follow the same pattern:
Words that add ‘es’ without doubling the final consonant:
- bus → buses
- plus → pluses
- virus → viruses
- census → censuses
- campus → campuses
Words that double the final consonant before adding ‘es’:
- kiss → kisses
- miss → misses
- fuss → fusses
- moss → mosses
- truss → trusses
The key difference? Words ending in a single ‘s’ preceded by a single vowel typically double the ‘s’ before adding ‘es’ (following the pattern for adding suffixes to short-vowel words). However, in “bus,” the ‘u’ sound is long (technically a diphthong), so it doesn’t follow this pattern.
