Genus and Species

Some concepts are broader than other concepts. ANIMAL is broader than DOG because there are other kinds of animals besides dogs.

If all the referents of one concept are included in another, but one concept refers to more things than the other, then the broader concept is called the genus, and the narrower one is called the species.

If a species is a file folder, a genus is a file drawer containing many folders.

Example:

ANIMAL is the genus, and all the different kinds of animals, such as DOG and CAT, are species of this genus. This is so because all the referents of the concept DOG are included in the concept ANIMAL, but the concept ANIMAL refers to more things than dogs.
