The act of cutting or separating the limbs from a body or the state of being cut apart.
The horror movie included a scene of dismemberment that shocked the audience.
Dismemberment is formed from "dis-" (meaning apart) and "member" (from Latin "membrum", meaning limb or part). The suffix "-ment" (meaning the action or result of) indicates the process or state of being. Thus, dismemberment refers to the action of taking apart or separating limbs or parts from a body.
Think of 'taking apart' ('dis-') the 'limbs' ('member') of a body, which helps you remember that dismemberment means the act of separating limbs.
