Etymology

Origin of organization

First recorded in 1375–1425; late Middle English organizacion, from Medieval Latin organizātiōn-, stem of organizātiō, equivalent to organizāt(us) “arranged” (past participle of organizāre “to contrive, arrange”; see organize) + -iō -ion


Explanation

An organization is a group of people who work together, like a neighborhood association, a charity, a union, or a corporation. You can use the word organization to refer to group or business, or to the act of forming or establishing something. It can also refer to a structure for classifying things or to a system of arrangement or order. When your English teacher tells you you need to work on the organization of your essay, she's using this last meaning. This word derives from an Old French verb meaning "to combine into an orderly whole."
