1, 2. 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.
