Thank you very much for your view. For a long time I thought that "each other" is used to refer to two people or things, "One another" to refer to more people or things. Recently I looked them up in OALD and was amazed at what I found:
Each other: used as the object of a verb or preposition to show that each member of a group does sth to or for the other members
One another: is used when you are saying that each member of a group does sth to or for the other people in the group.
My questions are:
1. Does it mean that these two words are interchangeable?
2. If not, what is/are the difference(s)?
My understanding until now, for instance, "we love each other" would denote 1 person loves another one; while "we love one another" would denote more (than 2) people sharing the love between them.
Thank you all in advance and sorry for my long post.
P/S: I did search the forum and found nothing useful.
