Between, Among, and Proximity

Use between for two identified items, among for groups of three or more, and master next to, opposite, and near for describing relative position.

Between, Among, and Proximity Prepositions

The between/among distinction is a classic B1–B2 test point. The English Grammar Profile (Cambridge) identifies between/among confusion as one of the top 10 most frequent determiner and preposition errors at B1 level. Many learners overgeneralise 'between', using it even for groups, crowds, and collective settings where English requires 'among'.

Between — Two Specific Items

Use between when the two items on either side are individually identified:

The pharmacy is between the bank and the post office.
The park is between the library and the museum.
Just between you and me... (two specific people)

Among — Three or More, Undifferentiated Group

Use among when something is in the middle of a group or mass of things:

I found my keys among all the papers on my desk.
She was sitting among a large crowd. (not 'between')
The café is among all the small shops on the high street.

Next to, Opposite, Near

Next to — immediately adjacent, sharing a boundary: 'the café is next to the bookshop — they share a wall'.
Opposite — directly facing, across a road or space: 'the bus stop is opposite our house'.
Near — in the general vicinity: 'there's a supermarket near the station'.
