Emaciate is formed from "e-" (meaning out of or away) and "maciare" (from Latin, meaning to make thin). The word describes the process of making someone or something thin, often due to illness or lack of nourishment.
Think of 'making thin' ('maciare') by taking something 'away' ('e-') — that's why emaciate means to become very thin.
