Word Origin & Etymology

Formed from the verb 'curtail' plus the noun-forming suffix '-ment'. 'Curtail' originates from the 15th-century adjective 'curtal' (meaning having a docked tail), from Old French 'courtault', ultimately from Latin 'curtus' (shortened). Its modern spelling was influenced by folk etymology associating the second syllable with an animal's 'tail'.
