A useful definition:
In social science we discuss "cases", not in the legal sense, but in this sense:
a specific individual, organization, entity, event, or action, existing in a specific time and place.
We are often interested in identifying what general categories this specific case belongs to, what is its "type".
At a general level:
concepts: abstract or general categories that we (humans) apply to particular cases/instances. They abstract away from the highly specific, complex, and often unique features of reality.
Our thought and our language is rooted in concepts!
