Meaning

noun an anticipated outcome that is intended or that guides your planned actions

noun what something is used for

noun the quality of being determined to do or achieve something; firmness of purpose

originFrom Middle English purpos, from Old French purposer (“to propose”) (with conjugation altered based on poser), from Latin prō- (“forth”) + pōnere (“place, put”), hence Latin prōpōnō, prōpōnere. By surface analysis, pur- + pose (“halt, pause, put, place”).
