Question

what is the difference between among and with ....

Answer 1

It is often taught that “between” is used for 2 items and “among” for 3 or more.

But this is not completely accurate. The more accurate difference is this:

Between is used when naming distinct, individual items (can be 2, 3, or more)

Among is used when the items are part of a group, or are not specifically named (MUST be 3 or more)

Answer 2

Among means you are together i.e u are indulged inside the group but with means your are with them
They literally mean the same but there's a basic difference when u write among it means you are a part of that group since a long time but when u write with it means u just started
