Common Mistakes with the Plural of Company
If you are writing a business email, a report, or even a quick message to a colleague, you will often need to refer to more than one company. The correct plural form is companies. The most common mistake is writing “companys” or “companees,” both of which are incorrect. This guide explains the rule, shows you how to avoid the error, and gives you practical examples for real writing situations.
Quick Answer: What Is the Plural of Company?
The plural of company is companies. You change the -y to -i and add -es. This follows the standard English spelling rule for nouns that end in a consonant + -y.
- Singular: company
- Plural: companies
Never write “companys” or “companees.”
Why Do People Make This Mistake?
Many learners and even native speakers make errors because the rule for words ending in -y can feel inconsistent. For example, you might see “boy” become “boys” (just add -s), but “company” becomes “companies” (change -y to -i and add -es). The key difference is the letter before the -y. If a vowel comes before the -y (like o in “boy”), you simply add -s. If a consonant comes before the -y (like p in “company”), you change the -y to -i and add -es.
Comparison Table: Singular vs. Plural Forms
| Singular | Plural | Rule Applied |
|---|---|---|
| company | companies | Consonant + y → change y to i + es |
| industry | industries | Consonant + y → change y to i + es |
| factory | factories | Consonant + y → change y to i + es |
| boy | boys | Vowel + y → add s |
| day | days | Vowel + y → add s |
| key | keys | Vowel + y → add s |

Common Mistakes and How to Fix Them
Mistake 1: Writing “Companys”
This is the most frequent error. It looks like a simple typo, but it is grammatically wrong.
- Incorrect: “We have contracts with three different companys.”
- Correct: “We have contracts with three different companies.”
Mistake 2: Writing “Companees”
This mistake happens when someone tries to add -es but forgets to change the -y correctly.
- Incorrect: “The companees in this sector are growing fast.”
- Correct: “The companies in this sector are growing fast.”
Mistake 3: Using “Company” as a Plural
Some learners treat company as an uncountable noun or forget to change the form.
- Incorrect: “There are many company in the city.”
- Correct: “There are many companies in the city.”
Better Alternatives and When to Use Them
Sometimes you may want to avoid repeating the word companies. Here are some alternatives that work in different contexts.
Formal Alternatives
- Firms – Use in legal, financial, or professional contexts. Example: “Several firms have submitted bids.”
- Corporations – Use when referring to large, legally structured businesses. Example: “Multinational corporations often have complex tax strategies.”
- Enterprises – Use for businesses of any size, especially in entrepreneurial contexts. Example: “Small enterprises benefit from local support programs.”
Informal Alternatives
- Businesses – A general, neutral term. Example: “Many local businesses are closing early today.”
- Organizations – Broader term that includes non-profits. Example: “Several organizations are partnering for the event.”
When to Use “Companies” vs. Alternatives
Use companies when you want a neutral, standard term that fits most business writing. Use firms or corporations when you need a more formal or specific tone. Use businesses in everyday conversation or informal writing. Avoid switching terms in the same paragraph unless you have a clear reason.
Nuance: Formal vs. Informal Tone in Email and Conversation
In a formal email to a client or partner, you might write: “We are pleased to announce that our company will be working with two leading companies in the technology sector.” This sounds professional and clear.
In an informal conversation with a coworker, you could say: “I heard a couple of companies are hiring in our area.” This is natural and relaxed.
The word companies itself is neutral. It works in both formal and informal settings. The tone comes from the surrounding words and sentence structure, not from the plural form itself.

The possessive plural is “companies’.” For example: “The companies’ policies were reviewed.” This shows that something belongs to multiple companies.

Final Tip for Real Writing
When you are writing an email or a document, double-check any word that ends in -y before adding -s or -es. If the letter before the -y is a consonant, change the -y to -i and add -es. This rule applies to many common business words like industry (industries), strategy (strategies), and category (categories). Mastering this rule will help you avoid one of the most frequent mistakes in business writing.
