English has many expressions that look almost correct but can change meaning because of one small punctuation mark. โEach othersโ and โeach otherโsโ are a common example, especially when writing about relationships, shared actions, or things that belong to two or more people.
The confusion usually comes from not knowing when each other should stay as two separate words and when an apostrophe is needed to show possession. In standard English, each other is used when people do something mutually, such as helping each other or understanding each other.
Each otherโs, with an apostrophe and s, is used when something belongs to or is associated with another person in the group. Meanwhile, each others without an apostrophe is generally considered incorrect when possession is intended.
Quick Answer โก
“Each other’s” is correct it’s the possessive form used to show that two or more people/things possess or relate to something belonging to one another (e.g., “They borrowed each other’s books”). “Each others” is grammatically incorrect “each other” is never pluralized because it already refers to two or more parties.
Let’s break this down properly so it sticks. ๐
What Does “Each Other” Actually Mean?

Before we tackle the apostrophe drama, let’s understand the phrase itself.
“Each other” is a reciprocal pronoun. It’s used when two (or more) people do something to or with one another, and the action goes both ways.
Examples:
- Sarah and Tom love each other. ๐
- The two teams respect each other.
- My sister and I always help each other with homework.
Notice something? “Each other” never changes form based on plurality of the action it stays exactly as it is: e-a-c-h o-t-h-e-r. No “s” at the end. Ever.
So What About “Each Other’s”?

This is where the apostrophe comes in and it’s actually simple once you see the pattern.
“Each other’s” is the possessive form of “each other.” We use it when we want to show that something belongs to or is associated with the other person/people involved.
Examples:
- We often wear each other’s clothes. ๐
- They read each other’s minds sometimes. ๐ง
- The kids swapped each other’s lunches at school.
- My colleagues and I always check each other’s work before submitting.
In every example above, notice the pattern: [noun] belongs to each other โ so we add ‘s to show possession, just like we would with any other possessive noun (e.g., “John’s book,” “the dog’s bone”).
The Comparison Table ๐
Here’s a simple cheat sheet to keep this crystal clear:
| Form | Correct? | Meaning | Example |
| Each other | โ Correct | Reciprocal action between two or more people | “They trust each other.” |
| Each other’s | โ Correct | Possessive showing ownership/relation | “They trust each other’s judgment.” |
| Each others | โ Incorrect | Not a real grammatical form | ~~”They trust each others.”~~ |
| Each others’ | โ Incorrect | Not a real grammatical form | ~~”They borrowed each others’ books.”~~ |
๐ก Key takeaway: There is no version of “each other” with just an “s” and no apostrophe. It’s either:
- each other (no possession), or
- each other’s (showing possession)
That’s it. Just two correct forms!
Why Do People Get Confused? ๐
Here’s the psychology behind the mistake:
- Plural confusionย Since “each other” often refers to more than one person, people assume it should be pluralized like a regular noun (e.g., “friends” โ “friends'”). But “each other” is a fixed reciprocal pronoun, so it doesn’t work that way.
- Autocorrect isn’t always reliableย Some texting apps don’t flag “each others” as wrong, so the error slips through unnoticed.
- Speech habitsย In casual spoken English, the apostrophe is silent, so people don’t “hear” the mistake when they write it down.
- Similar-sounding possessivesย Words like “others'” (as in “other people’s things”) exist, which creates a false analogy with “each other’s.”
Memory Trick to Remember This Forever ๐ง โจ
Here’s a simple mnemonic:
“Each Other” is ONE unit it never wears a plural ‘S’ by itself, only an apostrophe-S when it OWNS something.”
Think of “each other” as a single, inseparable couple like Bonnie and Clyde. They always show up together as one phrase, and the only thing that changes is whether they’re holding something (possessive ‘s) or not (plain “each other”).
Another trick:
- If you can replace “each other” with “one another”, it stays the same in both cases:
- “They love one another” โ “They love each other” โ
- “They read one another’s minds” โ “They read each other’s minds” โ
- But you’d never say “one anothers”ย so don’t say “each others” either! ๐ซ

FAQs: People Also Ask ๐
1. Is “each others” ever correct?
No. “Each others” (without an apostrophe) is never grammatically correct in standard English. The correct forms are “each other” or “each other’s.”
2. What is the possessive form of “each other”?
The possessive form is “each other’s” formed by adding an apostrophe + s, just like with singular nouns.
3. Can I use “each other’s” for more than two people?
Yes! While traditionally reserved for two people, modern English commonly uses “each other’s” for groups of three or more as well (e.g., “The five roommates share each other’s clothes”).
4. Is “each others'” (apostrophe after the s) correct?
No, this form doesn’t exist in standard grammar. Since “each other” is not a plural noun, it never takes an apostrophe after an “s.”
5. What’s the difference between “each other” and “each other’s”?
“Each other” shows a reciprocal action (e.g., “They help each other”), while “each other’s” shows possession (e.g., “They help with each other’s problems”).
6. Is “each other” singular or plural?
Grammatically, “each other” functions as a reciprocal pronoun and isn’t classified as singular or plural in the traditional sense but it always refers to two or more entities.
7. Why do people confuse “each other’s” with “each others”?
Mostly due to spoken English (where the apostrophe is silent), autocorrect not catching the error, and false analogy with regular plural possessives like “friends'” or “teachers’.”
Final Takeaway:
In conclusion, โeach othersโ and โeach otherโsโ are not interchangeable. The correct form depends on whether you are showing possession. Each other is used when two or more people or things have a mutual relationship, while each otherโs shows that something belongs to or is connected to each person in the group. Each others without an apostrophe is generally incorrect in standard English.
Remembering this simple rule can help you avoid common grammar mistakes in everyday writing. You are writing an email, school assignment, social media post, or conversation, using the correct form will make your sentences clearer, more natural, and grammatically accurate.
