This is called a key attribute!
There are different types of key attributes!
Primary key is the key that is actually chosen, for example a social security number.
There is also a unique key, say our finger prints! they also uniquely identify humans, but usually we prefer to use social security number when we list people (a unique key could be a primary key if we chose so)
We could also identify people by their social security number and a name, but this is unnecessary, as social security number already gives a full identification. Such a reduntant key is called super key.

Explanation:
Suppose we have %~nxa, where we have two modifiers n and x, and a single variable a.
So, the n modifier after the tilde forces the index variable to expand only to the filename(by the n modifier) and the extension(by the x modifier).
It produces the filename and extension instead of the full path.
