Etymology

Origin of brake¹

First recorded in 1400–50; of uncertain origin; possibly a special use of obsolete brake “a bridle, curb,” from Middle Dutch braeke “(flax) brake” (a tool that separates flax fibers from their woody stems); akin to break

Origin of brake²

First recorded in 1400–50; late Middle English fernebrake “fern thicket, fernbrake,” Old English (fearn)bracu “bed of fern, (fern)brake,” akin to Middle Low German brake “branch, twig, tree stump”

Origin of brake³

First recorded in 1275–1325; Middle English brake, probably by back formation from braken “thicket of fern,” taken as plural; see bracken

Explanation

To brake is to stop. The noun brake is the pedal in the car that stops the vehicle when pressed. When you want to brake, step on the brake)! In Middle English breken meant things that stopped others, such as a bridle for a horse. If your bicycle screeches at the bottom of every hill, maybe you should have the brakes checked. French Poet Paul Valery saw a brake as a stopping agent for more than just a vehicle: “Man's great misfortune is that he has no organ, no kind of eyelid or brake, to mask or block a thought, or all thought, when he wants to.”
