Ontology

The philosophical study of the nature of being, becoming, existence, or reality, as well as the basic categories of being and their relationships, is known as ontology. Traditionally classified as a subfield of metaphysics, ontology frequently deals with questions about what entities exist or can be said to exist, as well as how such entities can be grouped, related within a hierarchy, and subdivided based on similarities and differences. Ontology, in its most basic form, is the study of what is meant by the word 'thing' in context.
