You’re typing a quick email to a client, and your fingers stop on the most basic word in the message. Business or buisness? The u and i keep trading places in your head, and now the word looks wrong however you spell it.
That doubt is common. This word doesn’t sound the way it’s written, and fast typing swaps neighboring letters. Below you’ll get the answer, the reason behind the odd spelling, and a way to remember it.
Quick Answer
The correct spelling is business. When you’re choosing between business or buisness, only business is a real English word. It means a company, a trade, or work you need to do. “Buisness” is a typing slip with the u and i in the wrong order.
Rule: it’s bus + i + ness, like the word bus with iness added.
- She runs a small business from home.
- Please mind your own business.
- We have business in Chicago next week.
Why “Buisness” Looks Right (and the Real Reason Behind the Spelling)
Here’s the part most spelling pages skip. The spelling makes more sense when you know where the word came from.
According to Etymonline, business comes from Old English bisignes, which meant “care, anxiety, occupation.” That word was built from bisig (the ancestor of busy) plus the ending -ness. So business is really busy + -ness, and the spelling still shows its roots. That’s why it starts with bus, like busy.
The pronunciation drifted away from the spelling. Today we say BIZ-nis, and the i after the s is silent. Your ear gives you no clue about the middle letters, so your fingers have to remember. Add fast typing, where neighboring letters often swap, and “buisness” is an easy slip.
One more point from the same source: busyness (the state of being busy) is a separate, later word, first recorded in 1849. It was needed because business had moved away from meaning “busy.”
What Does Business Mean?
Business is a noun with several related meanings:
- A company: Her family business has been open for ten years.
- Buying and selling: Business was slow during the storm.
- Work or duty: He left early on business.
- A personal concern: That’s none of your business.
Buisness means nothing. It’s not a word, so the meaning of business or buisness never changes. Only the spelling does.
If you need other words, company, firm, and enterprise work for an organization. Trade and commerce fit buying and selling. Occupation and line of work suit a person’s job. They don’t always swap one for one, so match the meaning you need.
Common Business Phrases
These fixed phrases show how the word behaves in real sentences:
- Mind your own business: stay out of other people’s affairs
- None of your business: not your concern
- Business as usual: things continue as normal
- Out of business: no longer operating
- Get down to business: start the real work
- Mean business: be serious about acting
Etymonline dates business as usual to 1865 and mind your own business to the 1620s, so these are old expressions.
How to Pronounce Business
Say BIZ-nis (/ˈbɪznɪs/), with the stress on the first syllable. It has two syllables even though it looks longer. The i after the first s isn’t pronounced, which is why the word is so easy to spell wrong by sound.
Business Word Forms
Every form keeps the same spelling pattern:
| Form | Meaning | Example |
|---|---|---|
| business | a company or trade | She started a business. |
| businesses | more than one | Local businesses are hiring. |
| business’s | belongs to one | The business’s website is new. |
| businesses’ | belongs to several | The businesses’ owners met. |
| businessman / businesswoman | person in business | The businesswoman signed the deal. |
| businesslike | serious and efficient | She had a businesslike tone. |
| busyness | being busy | Her busyness left no time for lunch. |
Don’t mix up business and busyness. They look alike, but they mean different things.
Business Spelling: Letter by Letter
Business has eight letters: B-U-S-I-N-E-S-S. The u comes before the first s. The i comes after it. They never sit side by side, so “ui” is always the mistake.
If it helps, break it into chunks as you type: bus, i, ness. Or remember that busy starts with the same three letters.
Common Mistakes
Buisness. The u and i swap places. Fix: business.
Bussiness. An extra s sneaks in after the u, probably from words like discussion. Fix: business.
Busness. The silent i gets dropped because you can’t hear it. Fix: business.
Busines. The last s is left off, since the word ends in a soft sound. It needs a double s.
Bisness. This is spelling by sound alone. The u is easy to forget.
Buisiness. A second i gets added. The word has only one.
Real-Life Examples
- Work: “Our business hours are nine to five.”
- School: “She wrote her essay on a local business.”
- Social media: “Small business owners shared tips all week.”
- Daily life: “The bakery down the street is open for business.”
- Customer service: “Thank you for your business, and have a great day.”
Expert Tips
Fix it where people see it first. Subject lines, invoice headings, and email signatures are the places a typo hurts most, and they’re easy to skip when you proofread. Read those twice.
Set up autocorrect. Add shortcuts that turn buisness, bussiness, and busness into business. It takes a minute and catches the typo before a client does.
Search before you publish. Use Find for the common misspellings. Spellcheck often ignores file names, URL slugs, and text inside images, so a typo can hide there.
Check brand names separately. Some companies spell words in unusual ways on purpose. If you see an odd spelling in a name, confirm it on the official site before you “fix” it.
