What does ontologist mean?
An ontologist is a specialist in ontology, the philosophical inquiry into existence, the nature of being, and the relationships between different kinds of entity. The role is especially associated with metaphysics, where ontologists examine questions such as what it means for something to exist, whether properties belong to objects themselves, and how physical, mental, and abstract entities are related. In computer science, an ontologist may instead create or maintain a formal system for representing information, assigning categories and relationships to concepts so that machines can process them consistently. The word is uncommon outside academic and technical contexts and normally implies expertise rather than general familiarity with philosophy. It comes from the same Greek foundation as “ontology” and “ontic,” all of which concern the nature of being. The term is useful because it distinguishes a person who studies questions of existence from a philosopher whose primary field may be ethics, logic, knowledge, or another branch of philosophy.

Ontology asks what it means for something to be; biology asks what it means to be alive.

Where does ontologist come from?
“Ontologist” was formed in English from “ontology” and the specialist suffix “-ist.” “Ontology” combines the Greek combining form on-, from on or ontos meaning “being” or “that which exists,” with -logia, meaning the study of something. The word therefore literally means a specialist in the study of being.
