Etymology

Origin of viable

First recorded in 1820–30; from French, from vi(e) “life” (from Latin vīta; see vital) + -able -able


Explanation

When something is viable, it has the ability to grow or function properly. A viable seed can develop into a plant, while a viable company has the resources to succeed. The adjective viable refers to something able to function properly and even grow. It is made up of the Latin root vita, which means "life," and the ending -able, which means "to be possible." In terms of science or botany, when a plant is viable it can live and flourish in an environment such as a cactus in the desert. Consider also the Wright brothers, who were the first to develop a viable airplane after many tries and spectacular failures.
