Usage notes

In the field of philosophy there is some variation in how the term ontology is used. Ontology is a much more recent term than metaphysics and takes its root meaning explicitly from the Greek term for being. Ontology can be used loosely as a rough equivalent to metaphysics or more precisely to denote that subset of the domain of metaphysics which is focused rigorously on the study of being as being.
