Among vs. Between
“Between” is used for distinct, individually identified people, things, places, times, or choices; “among” is used for being part of, surrounded by, or included within a group or mass. The old rule that between is only for two and among only for three or more is too simple.
Use “between” when the items are distinct or separately identified, even when there are more than two. Use “among” when something belongs within, is distributed through, or is surrounded by a group.

Quick tests
Structure test
Are the people/things treated as distinct points or separate relationships?
If yes: “Between” is often appropriate even with more than two items.
If no: If the sense is “within/surrounded by a group,” “among” is usually the better fit.
Caveat: Do not use a simple two-versus-three count as the rule; the structure of the relationship matters.
Examples
The agreement was negotiated between the three departments.
The departments are treated as distinct parties.
She felt comfortable among the other volunteers.
The meaning is membership within a group.
Further guidance
Common Trap
Do not automatically switch to “among” simply because three or more people or things are involved. “Between the three finalists” can be natural when the finalists are treated individually.
Core Rule
The practical distinction is separateness, not merely the number of items. Cambridge notes that between commonly connects distinct items and can also be used with more than two, while among presents things as part of a group or mass.
Fast Test
If you can picture the participants or options as distinct points or pairs, “between” is often the better fit. If the meaning is “within the group” or “surrounded by the group,” choose “among.”
