Classification is related to categorization. When we classify, we are arranging people, objects, or ideas into groups of its kind or class according to its shared characteristics.

All things can be divided into two classes: animate (living things) and inanimate (things having no life). Objects can be placed in a certain general classes because of their resemblance, purpose, or use.

Other general classes are: birds, reptiles, flowers, fruits, minerals, liquids, apparel, occupations, places, utensils, ships, games, instruments, coins, and stamps.
