Did You Know?
Projection has various meanings, but what they all have in common is that something is sent out or forward. A movie is projected onto a screen; a skilled actress projects her voice out into a large theater without seeming to shout; and something sticking out from a wall can be called a projection. But the meaning we focus on here is the one used by businesses and governments. Most projections of this kind are estimates of a company's sales or profits--or of the finances of a town, state, or country--sometime in the future.
