"Among" and "between" are two prepositions that have separate usages. In fact, all they do is separate: "Among" describes action in a group of three or more, while "between" is action in a group of two, only.

"Among" Examples

"Among" is defined as "in the midst of" or "surrounded by," and is used when referring to a group: "She sat among the students." The song made popular by Connie Francis,"Among My Souvenirs," refers to a collection of keepsakes, while Iago, in Shakespeare's "Othello," makes reference to a group of party-goers as "among'st this flock of drunkards."

"Between" Examples

Merriam-Webster's dictionary defines "between" as "in the space/time that separates two": "He sits between the two of them" or "she is torn between two lovers." It can also, however, refer to more than two of a group if each member or element is considered a separate entity: "Between Kathy, Jane and myself there exists a permanent bond."
