classifications
Ways of grouping
Classifications are categories into which things are sorted based on shared characteristics.
The term implies a systematic arrangement: The library uses the Dewey Decimal classification.
Scientific classification organizes living things into hierarchies of kingdom, phylum, class, and so on.
Security classifications restrict access to sensitive information: top secret classification.
To receive a classification is to be assigned to a category.
