Using Companies or Company’s (Correct Grammar + Examples)

Is it companies or company’s? Or companies’? Using the apostrophe in the English language typically provides pluralization to the word that it is modifying. Adding an apostrophe can suggest that there is possession. And many amounts of certain things. For example, “Sonia’s book is missing.” In this sentence, the possession of the book is to Sonia, the person. This is how an apostrophe can modify singular nouns. An apostrophe can also modify compound nouns and create joint or separate possession.

Why is there confusion between Company’s and Companies?

The word “companies” and “company’s” sound identical. Although one form, given the use in a sentence, is grammatically correct, while the other form is incorrect. The word “companies” is the correct plural form of the word company. And the word “company’s” is the correct possessive form of the word “company.”

How to use the apostrophe correctly

The possessive singular noun is made by adding an apostrophe and the letter “s” to the singular noun in question, regardless of whether the singular noun ends in an “s” letter.

When a plural noun has an “s” at the end, the possessive form of the noun is created by simply adding an apostrophe. When the noun ends in any other letter, the possessive form is made by adding both an apostrophe and an “s.”

How to remember which word form to use

It’s important to remember rules for pluralization and possession. The word company is a singular noun, it refers to a thing. And when we want to make it a plural noun, we turn it into “companies” And then as a possessive noun the word companies “company’s.”

Here is a simple trick to remember apostrophe rules:

Use apostrophe + “s” with nouns that don’t end in “s”. When a singular noun has possession over another noun (such as Sarah’s hat or mom’s cat), add an apostrophe + “s” to the end of the noun. The same rules apply for collective nouns and plural nouns that don’t end in the “s” letter.
