If you’ve ever written the plural of “bus” and hesitated between busses or buses, you’re not alone. This is one of those English spelling cases where both forms exist, but only one is correct in most situations.
At first glance, it feels like a simple plural rule. But English has a small twist here that makes it slightly confusing.
Let’s clear it up properly so you always choose the right form.
The Quick Answer
- ❌ Busses → mostly incorrect in modern usage (except rare cases)
- ✅ Buses → correct plural form of “bus”
So:
- “The city has many buses.” ✅
- “The city has many busses.” ❌ (generally incorrect)
Why This Confusion Happens
This mistake is very common, and it comes from a few simple reasons:
1. English plural patterns
Many words ending in “-s” or “-ss” sometimes double letters in plural forms (like “kiss → kisses”), so people assume “bus → busses.”
2. Historical spelling variation
Older English sometimes used “busses,” which still appears in rare contexts today.
3. Similar sounding words
“Buses” and “busses” sound identical when spoken, so spelling depends entirely on memory.
What Does “Buses” Mean?
Buses is the standard plural form of bus, referring to vehicles used for public transport.
Real-life examples:
- The buses are running late today.
- I take two buses to reach work.
- School buses arrive at 8 AM.
👉 This is the only correct plural in modern English.
Is “Busses” Ever Correct?
Yes—but only in a very limited context.
1. As a verb (rare usage)
“Busses” can be a verb meaning to kiss someone repeatedly (informal or old-fashioned):
- They bussed (or bussed) each other goodbye.
- He busses her on the cheek.
However, this usage is rare and often replaced by “kissed” in modern English.
2. Old or historical writing
Some older texts may still use “busses” as a plural of bus, but this is outdated.
Side-by-Side Comparison

|---|---|---|
| Meaning | Plural of bus (vehicles) | Rare verb or outdated plural |

| Commonality | Very common | Very uncommon |
Real-Life Examples (Clear and Natural)

Simple Trick to Remember
Here’s an easy way to avoid the mistake:
1. Think “bus + es”
👉 Just add -es, not extra letters.
2. Compare with similar words:
- class → classes
- bus → buses
3. Memory shortcut:
👉 “One bus, many buses no double S needed.”
A Small but Interesting Detail
The confusion comes from older English spelling rules where doubling consonants was more common in plural forms. Over time, English simplified “bus → buses,” but some older variations like “busses” remained in niche usage.
Today, language standards strongly prefer buses in all modern writing.
Common Mistakes to Avoid
- Adding double “s” out of habit
- Assuming all plurals ending in “s” double letters
- Using “busses” in formal writing
Examples:
- The busses are delayed. ❌
- The buses are delayed. ✅
Quick Memory Check

Conclusion
The difference between buses vs busses is simple once you know the rule:
- Buses → correct plural of bus (always use this)

Quick trick: “Bus + es = buses, no exceptions.”
Once you remember that, this common spelling mistake disappears and your writing becomes instantly more accurate and professional.
