Etymology
Origin of flail
First recorded before 1100; Middle English fleil (noun), Old English flighel (probably misspelling of unattested flegil ), cognate with Dutch vlegel, German Flegel, from unattested West Germanic flagil-, from Late Latin flagellum “flail,” Latin: “whip, scourge”; see flagellum
Explanation
To flail means to wave around wildly. If you are stranded on a deserted island and you see a ship in the distance, it’s a good idea to flail your arms in the air to get the captain’s attention. Flail originates with the Latin word flagellum, which is a whip. It is also related to the noun flail, a stick with a swinging attachment to it, used to thresh grain. As a verb, it most often refers to arms, but can also involve the whole body, especially if someone is a very wild dancer. Other things can flail as well. If someone admits that his business is flailing, it’s probably lacking direction and not doing very well.
