Etymology

Origin of curtail1

First recorded in 1425–75; late Middle English curtailen “to restrict” (said of royal succession or inheritance), probably a conflation of Middle French courtau(l)d ( see curtal) and Middle English taillen “to cut” ( see taille, tailor 1)

Explanation

To curtail something is to slow it down, put restrictions on it, or stop it entirely. If I give up cake, I am curtailing my cake-eating. Curtail is an official-sounding word for stopping or slowing things down. The police try to curtail crime — they want there to be less crime in the world.
