Etymology

Origin of tool

First recorded before 900; Middle English (noun); Old English tōl; cognate with Old Norse tōl “tools”; akin to taw ²

Explanation

A tool is an instrument that you use to help you accomplish some task. If you are going to build a bookcase, you'll need the proper tools, like a saw, a drill, and a tape measure. A tool is also something that you use to perform the duties of a certain profession. The tools of a kindergarten teacher's trade include construction paper, glue sticks, and safety scissors. As a verb, tool can mean to drive aimlessly just for fun, the way you might tool around town in your convertible on a beautiful summer day.
