The difference between "among" and "between" (pre-intermediate, intermediate, upper-intermediate and advanced level)

We use among when we consider people or things as a group.
E.g. His house is among the trees.

We use between when we are talking about two or more clearly separate people or things.
E.g. Our house is between the woods, the river and the village.

Between can be used to talk about intervals and time limits.
E.g. We need two metres between the windows.
E.g. I’ll be at the office between nine and eleven.
