entity, emobodied entities, entities; entity


Definition: An entity is something that exists in itself, actually or potentially, concretely or abstractly, physically or not. It need not be of material existence. In particular, abstractions and legal fictions are usually regarded as entities. In general, there is also no presumption that an entity is animate. The study of entities is ontology , the studies of what exists. is an attempt of ontology in the study of human diseases ( human pathology ). This need the isolation , nomination , annotation and description of structures , processes , techniques and concepts used for the study of human diseases .

The word may refer, for example, to Bucephalus, the horse of Alexander; to a stone; to a cardinal number; to a language; or to ghosts or other spirits.

The word "entitative" is the adjective form of the noun entity. Something that is entitative is considered in its own right.


In philosophy, ontology is about the recognition of entities. The words ontic and entity are derived respectively from the ancient Greek and Latin present participles that mean ’being’.
