Synonyms & Antonyms

Root Explanation

Treadmill is formed from "tread" (from Old English *tredan*, meaning to step or walk) and "mill" (from Old English *mylen*, meaning a device for grinding). The word describes a device that allows one to walk or step in place, mimicking the action of walking while remaining stationary, similar to a mill's repetitive motion.

Memory Tip

Think of 'treading' as stepping or walking, and 'mill' as a device that grinds. A treadmill is a machine that lets you step in place, just like a mill works continuously.
