The Origin of Eachother or Each Other

The phrase each other has been part of English for hundreds of years. It combines two separate words:

• Each means every individual one.
• Other means another person or thing.

Together, each other expresses a mutual relationship between two or more people.

Examples:

• They love each other.
• The students helped each other.

Over time, many people began writing it as eachother because it sounds like one word in speech. However, dictionaries and grammar guides still recognize only the two-word form.

Unlike words such as everyone or someone, each other has never become one combined word in standard English.
