Meaning and Basic Overview of Each Other
Each other is a reciprocal expression in English. It shows that two or more people perform the same action toward one another.
For example:
- Sarah and John helped each other with homework.
- The two friends always support each other.
- The team members respect each other.
In these examples, the action goes in both directions. Sarah helps John, and John helps Sarah. The friends support one another, and the team members share mutual respect.
The phrase is made of two separate words:
- Each means every individual person or thing in a group.
- Other means a different person or thing from the one already mentioned.
Together, each other means “one person to another person” or “members of a group to other members of the same group.”
Is It Eachother or Each Other?
The correct spelling is always:
✅ Each other
The incorrect spelling is:
❌ Eachother
English does not combine these two words into one word. Although many people write “eachother” because it sounds like one word, standard English grammar requires a space between them.
Examples:
Correct:
- We should respect each other.
- They talked to each other every day.
Incorrect:
- We should respect eachother.
- They talked to eachother every day.
A useful way to remember this rule is to treat each other like other two-word phrases such as:
- one another
- one day
- every time
- all together
Grammar Rules for Using Each Other
Understanding the grammar behind each other makes it easier to use correctly.
Each Other as a Reciprocal Pronoun
Each other works as a reciprocal pronoun. It shows a mutual relationship between people or groups.
Examples:
- The children shared toys with each other.
- The neighbors helped each other during difficult times.
- The players congratulated each other after the match.
The phrase tells us that the action is not happening in only one direction.
Each Other With Possessive Form
The possessive form of each other is:
each other’s
It shows ownership or connection.
Examples:
- They know each other’s names.
- The students read each other’s essays.
- The friends respect each other’s opinions.
The apostrophe comes before the “s” because it shows possession.
Difference Between Each Other and One Another
Many people use each other and one another interchangeably, and in modern English both are generally accepted.
Traditionally:
- Each other was used for two people.
- One another was used for more than two people.
However, modern grammar does not strictly follow this rule.
Examples:
Two people:
- The couple loves each other.
More than two people:
- The team members support each other.
Both sentences are correct.
Today, each other is much more common in everyday English.
Common Mistakes When Using Each Other
Many learners make mistakes with this phrase. Here are the most common ones.
Writing Eachother as One Word
The biggest mistake is combining the words.
Incorrect:
- They care about eachother.
Correct:
- They care about each other.
Using Each Other Without a Mutual Meaning
Each other requires a shared action.
Incorrect:
- I looked at each other.
Correct:
- We looked at each other.
The subject must involve two or more people or things.
Confusing Each Other With Themselves
Each other means people affect one another.
Themselves means people act on their own.
Examples:
- They blamed each other. (They blamed one another.)
- They blamed themselves. (Each person blamed their own self.)
History and Development of the Phrase
The phrase each other has been part of English for centuries. It developed from two common English words that existed separately.
The word each comes from Old English “ǽlc,” meaning every individual person or thing. The word other also comes from Old English and refers to a different person or thing.
Over time, these words began appearing together to express mutual relationships.
As English developed, reciprocal expressions became important because they allowed speakers to describe social connections, cooperation, and shared actions more clearly.
Today, each other remains one of the most frequently used expressions in English communication.
