What Is the Plural of Company?
The plural of company is companies. You change the -y to -i and add -es. This is the standard plural form in business English and everyday use. Whether you are writing an email, preparing a report, or speaking in a meeting, companies is the correct word when referring to more than one business organization.
Quick Answer
Singular: company
Plural: companies
Rule: For nouns ending in a consonant + -y, change the -y to -i and add -es.
Why It Is Not “Companys”
A common mistake is to write companys. This spelling is incorrect because company ends in a consonant (y is acting as a vowel sound here, but the letter y follows a consonant). The rule for regular plurals in English says that when a noun ends in a consonant + -y, you must change the -y to -i and add -es. So company becomes companies. Think of similar words: city becomes cities, baby becomes babies, and factory becomes factories.
Formal and Informal Use
Formal Contexts
In formal business writing, such as annual reports, legal documents, or official emails, companies is the standard plural. You might see phrases like “several companies in the sector” or “both companies agreed to the merger.” There is no alternative plural form that is considered more formal; companies works in all registers.
Informal Contexts
In casual conversation or internal team messages, companies is still the correct plural. Native speakers do not shorten it or change it. For example: “We work with three different companies on this project.” The word is the same whether you are in a boardroom or chatting with a colleague.

Natural Examples
Here are examples that show how companies is used in real writing and conversation.
- Email context: “We have contacted several companies about the partnership opportunity.”

Common Mistakes
Mistake 1: Writing “Companys”
This is the most frequent error. Because company ends in -y, some learners think they can just add -s. But the rule requires the change to -ies. Always write companies.
Incorrect: “The two companys merged last year.”
Correct: “The two companies merged last year.”
Mistake 2: Using “Company’s” as a Plural
An apostrophe + s (company’s) shows possession, not plurality. Do not use it to mean more than one company.
Incorrect: “We work with several company’s.”
Correct: “We work with several companies.”
Mistake 3: Confusing “Companies” with “Companions”
Companions means friends or people you travel with. It is a different word. Stick with companies for business contexts.
Better Alternatives and When to Use Them
Sometimes you may want to vary your language instead of repeating companies. Here are some alternatives that work in business English, along with guidance on when to use each.
- Firms – Use in formal or neutral contexts, especially in finance or law. Example: “Several law firms attended the conference.”
- Corporations – Use when referring to large, legally incorporated businesses. Example: “Multinational corporations dominate the market.”
- Businesses – A general term that can replace companies in most contexts. Example: “Small businesses are struggling with inflation.”
- Enterprises – Slightly more formal; often used for large or ambitious projects or organizations. Example: “State-owned enterprises are undergoing reform.”
- Organizations – Broader term that includes non-profits and NGOs. Example: “Both organizations signed the agreement.”
When you are unsure, companies is always safe. Use the alternatives only when they fit the specific tone or industry.

Frequently Asked Questions (FAQ)
1. Is “companys” ever correct?
No. Companys is not a standard English word. The only correct plural form is companies. Some brand names or proper nouns may use Companys as a stylized spelling, but that is a rare exception and not a general rule.
2. Can “company” be used as a plural in some contexts?
No. Company is always singular. If you mean more than one, you must use companies. There is no collective noun usage that keeps it singular for plural meaning.
3. What is the possessive plural of “company”?
The possessive plural is companies’ (with the apostrophe after the -s). Example: “The companies’ CEOs met yesterday.” This shows that something belongs to multiple companies.
4. Is “company” countable or uncountable?
Company is a countable noun when it means a business organization. You can say “one company,” “two companies,” and so on. However, company can also be uncountable when it means companionship (e.g., “I enjoy your company”). In that uncountable sense, it has no plural form.
Final Note
Remembering the plural of company is simple once you know the rule: consonant + -y becomes -ies. Use companies in all your business writing and speaking. Avoid companys and the possessive company’s when you mean more than one. With practice, this will become automatic.
