Etymology

Origin of schema

First recorded in 1790–1800; from Greek schêma “form, shape, appearance”

Explanation

If you were just commissioned to modernize your town's library, the first thing you'll make is a schema: an outline of your plan for reinventing libraries. Schema sounds like scheme, but they have different nuances. You scheme to snatch a cookie from the jar. A schema is more of a master plan. It can also just be an organized vision. If you have a master concept about how the world works, that's your world organization schema. Someone with an insanely big idea about how to change the world has "a grand schema." Now she just needs to make a practical schema for actually making that change.
