Related Words

Task, chore, job, assignment refer to a definite and specific instance or act of work. Task and chore and, to a lesser extent, job often imply work that is tiresome, arduous, or otherwise unpleasant. Task usually refers to a clearly defined piece of work, sometimes of short or limited duration, assigned to or expected of a person: the task of pacifying angry customers; a difficult, time-consuming task. A chore is a minor task, usually one of several performed as part of a routine, as in farming, and often more tedious than difficult: the daily chore of taking out the garbage; early morning chores of feeding the livestock. Job is the most general of these terms, referring to almost any work or responsibility, including a person's means of earning a living: the job of washing the windows; a well-paying job in advertising. Assignment refers to a specific task allocated to a person by someone in a position of authority: a homework assignment; a reporter's assignment to cover international news.

Etymology

Origin of task

First recorded in 1250–1300; Middle English noun, from Medieval Latin tasca, variant of taxa tax ( def. )

Explanation

A task can be big or small, easy or really hard — but it's never more than a job that needs to get done. Chop chop! There's a task that needs completing, and you're just the person for the job. If you're smart though, you'll figure out a way to task someone else with it, or assign it elsewhere. Task comes to us all the way from the Latin word taxare, which in its earliest days meant "to impose a tax on." So much like the filling out of your tax forms, most tasks are considered chores.
