Found in dictionaries	✅ Yes	❌ No
Used in school writing	✅ Yes	❌ No
Used in professional writing	✅ Yes	❌ No

Easy Rule

Never write:

❌ eachother

Why Is “Each Other” Written as Two Words?

Many English learners wonder why these words stay separate.

The reason is simple.

Each and other work together as a grammatical phrase rather than forming one compound word.

English keeps them separate because they have different grammatical jobs.

Think of similar expressions like:

• every day
• one another
• no one

These are also written as separate words.

The same rule applies to each other.

Grammar Rule Explained in Simple Words

Whenever two or more people share the same action, use each other.

Formula

Person + Verb + Each Other

Examples

• We trust each other.
• The children hugged each other.
• My friends call each other every weekend.
• The players congratulated each other after the match.
• Good neighbors help each other.

Notice that both sides perform the action.

Each Other vs One Another

Many people also ask whether each other and one another mean the same thing.

Today, they are almost always interchangeable.

Traditionally:

• Each other referred to two people.
• One another referred to three or more people.

Modern English no longer follows this rule strictly.

Comparison Table

Each Other	One Another
Usually for two or more people	Usually for two or more people
Very common	Slightly more formal
Everyday English	Formal writing
Same meaning in modern English	Same meaning in modern English

Examples

• The brothers helped each other.
• The brothers helped one another.

Both sentences are correct.

Another example:

• The students encouraged each other.
• The students encouraged one another.

Again, both are acceptable.

Why Do People Write “Eachother”?

There are several reasons why this mistake is so common.

1. The Words Sound Like One Word

When speaking quickly, each other sounds like one word.

This leads many writers to combine them.

2. Spell Check Is Ignored

Some people overlook spelling suggestions while typing.

3. Confusion with Compound Words

English has many compound words like:

• everyone
• somebody
• everything

Because of these examples, people assume eachother should also be one word.

However, English grammar treats each other differently.

4. Fast Typing

Typing quickly on phones and computers often causes people to remove the space between the two words.

Key Takeaways

• Each other is always the correct spelling.
• Eachother is a spelling mistake.
• Use each other whenever two or more people share the same action.
• Modern English always writes the phrase as two separate words.
• If you’re unsure, remember: “Each” and “other” always need a space.
