Expert writing Tips
Best practice
Always use the possessive apostrophe ('s) with "each other" when indicating ownership or a relationship where one entity possesses something in relation to the other. For instance, "They respect each other's opinions" is grammatically correct.
Common error
Avoid omitting the apostrophe in possessive constructions. "Each others" is incorrect; the proper form is "each other's" when indicating possession.
