Companies is the correct plural form of company, while companys is incorrect in standard English.
This spelling confusion happens because many English words simply add -s to become plural, but nouns ending in a consonant followed by y follow a different grammar rule.
Understanding this rule helps you write more accurately in emails, business documents, school assignments, and everyday communication.
In this guide, you’ll learn the correct spelling, why people make this mistake, the grammar behind it, the word’s origin, and when to use companies with confidence in both British and American English.
Quick Answer
The correct spelling is companies.
Companys is a spelling mistake and should never be used as the plural of company.
The word company becomes companies because nouns ending in a consonant followed by y change the y to ies when forming the plural.
Correct Examples
- Our company owns several companies.
- Many technology companies are hiring this year.
- The government supports small companies.
Incorrect Examples
- ❌ Several companys joined the event.
- ❌ These companys are expanding quickly.
- ❌ International companys invest in the region.
Quick Rule
If a singular noun ends in a consonant + y, remove the y and add -ies.
- Company → Companies ✅
- City → Cities ✅
- Country → Countries ✅
- Baby → Babies ✅
Never write companys when you mean more than one company.
The Origin of Companies or Companys
The word company comes from the Old French word compaignie, which originally meant companionship, association, or a group of people. It can be traced even further back to the Latin phrase cum panis, meaning with bread, referring to people who shared meals together.
Over time, the meaning expanded to describe groups of merchants, military units, trading organizations, and eventually business organizations. Today, a company refers to a business, corporation, firm, enterprise, or legal organization.
The plural form companies follows a long-standing English grammar rule rather than a special business rule. English changes nouns ending in a consonant plus y by replacing y with ies.
That is why:
- Company → Companies
- Party → Parties
- Library → Libraries
- Family → Families
The spelling companys has never been accepted in standard English dictionaries. It usually appears because writers simply add -s without applying the plural spelling rule.
British English vs American English Spelling
Unlike words such as colour/color or organisation/organization, there is no spelling difference between British English and American English.
Both use company for the singular and companies for the plural.
| British English | American English | Correct? |
|---|---|---|
| company | company | ✅ Yes |
| companies | companies | ✅ Yes |
| companys | companys | ❌ No |
British English Examples
- Several companies signed the agreement.
- British companies continue to expand overseas.
- Many small companies received funding.
American English Examples

- Local companies created thousands of jobs.
- Several startup companies attracted investors.
Whether you write for readers in the United States, United Kingdom, Canada, Australia, or New Zealand, the correct plural spelling is always companies.
Which Spelling Should You Use?
The answer is simple: always use companies when referring to more than one company.
For American English
Use companies in business reports, academic writing, websites, contracts, emails, and news articles.
Examples
- American companies reported higher profits.
- Several software companies launched AI tools.
For British English
British English follows exactly the same grammar rule.
Examples
- Many British companies export goods worldwide.
- Insurance companies introduced new policies.
For Canadian English
Canadian English also uses companies.
Examples

- Energy companies announced new projects.
For Australian and New Zealand English

This spelling is accepted by major dictionaries, style guides, universities, publishers, and professional editors around the world.
A Simple Memory Trick

- Family → Families ✅
If the word ends in consonant + y, replace the y with ies to make it plural. Never add only -s after the y.
