definition of categorize
Categorization is the act of sorting and organizing things according to group, class, or, as you might expect, category. This noun is very similar in meaning to assortment, classification, and compartmentalization.. When we discuss the differences between mammals and birds, or reptiles and amphibians, we are talking about the categorization of the animal kingdom. Another form of categorization is the way libraries shelve their books by subject, genre, and reading level.
