Subtypes

Let’s learn about subtypes.

We'll cover the following...

Introducing subtypes by specialization

The concept of a subtype, or a subclass, is a fundamental concept in natural language, mathematics, and informatics. For instance, in English, we say that a bird is an animal, or the class of all birds is a subclass of the class of all animals. In linguistics, the noun “bird” is a hyponym of the noun “animal.”
