IPA: /əˈsaɪnmənt/
KK: /əˈsaɪnmənt/
A task or piece of work that someone is given to do, often as part of their job or studies.
The teacher gave us an assignment to complete over the weekend.
Assignment → It is formed from "assign" (from Latin "assignare", meaning to designate or allocate) and the suffix "-ment" (meaning the action or result of). The word "assignment" refers to the action or result of designating or allocating a task or responsibility.
Think of the action of 'designating' a task ('assign') and the result of that action ('-ment') — that's what assignment means.
