Is there any specific rule for using "each other" instead of "another" or vice versa.
I had come across a question involving these answer choices but the explaination for the answer did not cater to 'each other' or 'another'
If someone knows any details about this, request you to post.
p.s. If i come across the question again, I will surely post the same.
Agree with above comments: we should use "Each other" talking about 2 persons while "another" is used when more than two are involved.
Here are simple examples:
1.John and Vera love each other (only two people are involved)
2.In our team we value one another (more than two are involved)
Also, when you say "each other" - you refer to the relation between the two people; when you say "another" - you refer to the third party.
