Buses is the overwhelming standard plural spelling for large passenger vehicles. Busses is an acceptable but rare secondary variant for the plural noun, and it historically refers to the verb buss, which means to kiss or to clear restaurant tables. To avoid errors in modern writing, always use buses for vehicles.
What Is Busses or Buses?
The debate between buses and busses comes down to primary standard spelling versus rare historical variants.
- Buses is the dominant plural form of the noun bus (a large motor vehicle carrying passengers). It is also the most common third-person singular present tense verb form (e.g., “He buses tables at night”).
- Busses is a valid historical alternative plural for vehicles, but it is rarely used today. More uniquely, busses is the plural noun or present-tense verb derived from buss, an archaic word meaning “to kiss.”
Why It Matters
Using the wrong spelling can make your writing appear outdated or unintentionally ambiguous:
- Editorial & Professional Standards: Major style guides and global publishing houses mandate buses for public transport. Using busses in reports, news articles, or academic papers can look like a typo.
- Accidental Double Entendre: Because buss means a kiss, writing “She receives many busses every morning” could be interpreted as receiving many kisses rather than catching multiple commuter vehicles.
- Consistency across Global English: Standardizing on buses ensures seamless readability across American, British, Canadian, and Australian dialects.
The Core Rule
The Core Rule:
Always write Buses when referring to vehicles.
Reserve Busses only if you intentionally mean kisses or rare culinary table-clearing contexts where double s is specifically preferred.
- Buses = Standard plural for vehicles (1 s in the middle).
- Busses = Rare variant for vehicles / kisses / clearing dishes (2 s‘s in the middle).
How to Use It
Plural Noun (Vehicles)
When counting or referring to multiple transit vehicles, use buses:
- “Three school buses idling outside.”

When using the verb meaning to transport by bus or to clear dishes from restaurant tables:

- Alternative Verb (Less Common): Busses / Bussed / Bussing

Why People Make This Mistake
Understanding why the double-S spelling occurs helps clarify why the rule developed:
- Short Vowel Doubling Rule: In English phonics, a short vowel followed by a single consonant often doubles that consonant when adding a suffix (e.g., gas $\rightarrow$ gasses, quiz $\rightarrow$ quizzes, buss $\rightarrow$ bussed). Writers naturally expect bus to become busses.
- Historical Overlap: In the early to mid-20th century, busses was significantly more common in printed English than it is today.
- Spellcheck Tolerance: Most modern software dictionaries accept busses as a valid word because it exists as an archaic noun for a kiss and a secondary variant for vehicles.
Common Mistakes Checklist
- Doubling the S when making the noun plural:
- The Mistake: Writing “busses” when talking about transit.
- Why it happens: Overapplying short-vowel spelling rules.
- How to avoid: Remember that bus is an shortened clipping of omnibus, following simple plural addition (+s).
- Confusing Verb Conjugations (Bused vs. Bussed):
- The Mistake: Mixing up single-S and double-S forms across a document.
- Why it happens: Lack of consistent house style rules.
- How to avoid: Stick to single s across all forms: bus, buses, bused, busing.
- Assuming Busses is purely an error:
- The Mistake: Correcting historical poetry or older texts where busses means kisses.
- How to avoid: Recognize that buss (kiss) is a distinct headword in English dictionaries.
