Is It Each Others’ or Each Other’s (Correct Grammar + Examples)

Is it each other’s or each others’? 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 each other’s and each others’?

Making the word “other” plural can be challenging because it varies based on the way the word is getting used in a common sentence. For example, when we say “each other’s work” it is a singular pluralization of the word form. When we say “consider other’s opinions,” we use “others'” with the apostrophe at the end with no additional “s” letter, because there are many opinions we are referring to.

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

Remember that “other’s” is the correct singular plural form of the base form “other.” “Each other’s” is the correct form we use to refer to one. To remember the form to use, simply remember the inclusion of “each” means it is singular. Making “other’s correct.

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.
