kind, kinds, kindness, kindnesses

Definition:

The terms "kind" and "kinds" refer to groups or classifications of things that are connected by shared characteristics.

In the Bible, this term is specifically used to refer to the distinctive kinds of plants and animals that God made when he created the world.
Often there are many different variations or species within each "kind." For example, horses, zebras, and donkeys are all members of the same "kind," but they are different species.
The main thing that distinguishes each "kind" as a separate group is that members of that group can reproduce more of their same "kind." Members of different kinds cannot do that with each other.

Ways to translate this term could include "type" or "class" or "group" or "animal (plant) group" or "category."
