I often use the words amid/amidst instead of among/amongst and instead of between or surrounded by, but I could never understand it's meaning "in the middle of" as Cambridge dictionary and Oxford dictionary tell us that it has this meaning.
Examples that they provide still carry the meanings of "among/surrounded by".
- Our dream home, set amid magnificent rolling countryside.
- On the floor, amid mounds of books, were two small envelopes.
I also know that amid/amidst have meanings "during/with the accompaniment of/In an atmosphere or against a background of/through" but I almost never hear this word used with those meaning.
