Etymology

Origin of projection

First recorded in 1470–80; from Latin prōjectiōn- (stem of prōjectiō ) “a throwing forward”; see project, -ion

Explanation

When you push something away from a central structure, that's called projection. If you predict that the Jets will win tomorrow's game, that's a projection, too — you're pushing your mind away from the present and into the future. The Jets and projection actually have a common linguistic ancestor. Both the ject in projection and the word jet come from the Latin root jactus, which means "throw." A jet plane throws itself — or projects itself — away from a central structure (the Earth) and into the air.
