Etymology
Origin of imagination
First recorded in 1300–50; Middle English, Middle French, from Latin imāginātiōn- (stem of imāginātiō ) “mental image, fancy,” equivalent to imāgināt(us), past participle of the verb imāginārī imagine ( imāgin-, stem of imāgō image + -ātus -ate 1 ) + -iōn- -ion
Explanation
Imagination refers to the process of forming images or concepts in the mind, often images of things that are not really there. That shark in your bathtub must have been in your imagination — or was it? Often shunned for living in a dream world, imagination is behind unicorns, Big Foot, and excessive daydreaming. But it’s humans’ ability to picture what is not there, and to be resourceful and creative, that is behind many of our achievements. Maybe that’s why Albert Einstein said “Imagination is more important than knowledge.” After all, without a little imagination, we wouldn’t have the pyramids, the space shuttles, or the Star Wars trilogy.
