Nowadays, we can say in plain English: A set is a well defined collection of objects. The elements or members of a set can be anything: numbers, characters, words, names, letters of the alphabet, even other sets, and so on.
An infinite set is not finite. An example of a finite set is one with some number of elements. You can say an infinite number, but it is not fixed. An infinity is a process that uses induction on the natural numbers. Cantor showed however, that there is another sense of infinity.
