What's the difference between で and と


で and と particle can be used to mean "and" in english. For example:

彼女はお金持ち **で** きれい

Aさん **と** Bさんはいません

In the sentences above, both と and で means "and", but they are not
interchangeable. When would one use と and で to imply "and" in english?




In Japanese you can chain independent statements together by conjugating the
statement in the middle into the te-form and just sticking them together. This
is what's happening in your first sentence, with で being the te-form of だ.
There are two complete statements there: お金持ちだ and きれい. Those both work as
sentences by themselves.

The と particle is used for grouping nouns together. (It has other uses as well
that aren't relevant here.)

A noun by itself isn't a complete sentence, nor can it be conjugated, so the
first method doesn't work on the second sentence. And likewise, since the
first sentence isn't combining nouns, と doesn't work there.
