'Between' or 'Among': Which Is Correct?
Just between us: it's a complicated situation. by Merriam-Webster

... The two words have some degree of overlap, but also significant differences. Additionally, none of the above should be taken to mean that you may not have preferences in this matter, and you should feel entirely comfortable following your own self-imposed guidelines for when to use between and when to use among.

It should, however, be taken as a refutation of the over-generalizing rule that Frank Vizetelly espoused earlier in this article. It is not difficult to find cases in which among sounds wrong no matter what the number (when was the last time you heard anyone describe being “among the devil and the deep blue sea”?). And as for the question of whether between may be used for numbers greater than two, we have only to look elsewhere in Vizetelly’s own book to see that sometimes this works quite well.

Among may apply to any number; between applies to two only.
Bring, carry, fetch: Discriminate carefully between these words.
— Frank Vizetelly, A Desk-book of Errors in English, 1920

Discriminate carefully between these words, indeed.
