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)
Origin of curtail2
Probably alteration, by folk etymology, of curtal
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. A company may want to curtail their employees' computer time, so they spend more time working and less time goofing around. Teachers try to curtail whispering and note-passing in class. When something is curtailed, it's either stopped entirely or stopped quite a bit — it's cut short.
