Something multipurpose can be used for many different jobs. A multipurpose hall might hold PE, exams, and the school play. A multipurpose tool is one thing in a bag that covers several tasks. It is practical, everyday English — you see it on product boxes and building signs more than in novels. It is not a grand word. Though actually, shops stretch it: “multipurpose” on a label sometimes means “please buy this for more than one reason,” not that it is truly good at all of them. British writing often keeps the hyphen (multi-purpose); American writing often runs it together. Same word.

多功能；多用途。台灣商品包裝幾乎都寫「多功能」。
