覚え方のコツ Memory Tip
tread「足で踏む」＋ mill「回転して働く機械」の複合語なので、ベルトを踏んで回す運動器具と理解できる。run on a treadmill、use a treadmill のように前置詞 on とよく結び付く。日本語の「ランニングマシン」に当たり、屋外を走らず同じ場所で歩行・走行する器具である。
Break treadmill into tread, “step or press with the feet,” and mill, a machine traditionally driven by repeated movement. The literal picture is therefore a machine operated by treading. Modern users walk or run on its moving belt while staying indoors and in one place. Remember the common patterns run on a treadmill, walk on a treadmill, and use a treadmill at home. The preposition on reflects the fact that the person stands on the belt. Historically the device was used for labor and punishment before becoming familiar as exercise equipment.

treadmill の語源・成り立ち Etymology
treadmill は tread「踏む」+ mill「回して仕事をさせる装置」の複合語で、19世紀には囚人に踏ませる懲罰機械を指しました。tread は古英語 tredan、mill はラテン語 mola 系。tread や mill を知ると、『踏んで回す機械』から今の意味へつながります。
Treadmill is a compound of tread, meaning to step or press with the feet, and mill, a machine driven to perform work. Tread goes back to Old English tredan, while mill ultimately derives through Germanic and Latin forms associated with grinding. In the nineteenth century, treadmills included machines powered by people stepping repeatedly, notably prison labor devices. The name was later applied to indoor exercise machines with moving belts.
