What's the difference between the word kinds, types and classes?

Answer 1

In general usage, there's no real difference. In scientific classification, "class" has a specific position (which I don't remember). Sometimes when we refer to certain classes of people, we are talking about their socio-economic status, or their status by birth. Also, we use "kind" or "type" when describing persons mostly by their behavior. "He's the kind of guy who would give you the shirt off his back." "Her type of woman always means trouble."

Answer 2

There is absolutely no difference.
