Etymology

Origin of inelastic

First recorded in 1740–50; in- 3 + elastic

Explanation

Things that are inelastic are stiff and unbendable. Metal is often inelastic, while rubber generally isn't. If something's elastic, it's flexible and can easily bend back to its original shape. Inelastic is the opposite: Silly Putty is elastic, but a wooden block is inelastic. This adjective is also used figuratively in economics to mean "not changing much in response to variables." If the price of wheat always stayed the same, no matter what, it would be considered inelastic.
