Etymology

Origin of pedometer

1723; < French pédomètre, equivalent to péd- (learned use of Latin ped- foot (stem of pēs ); pedi- ) + -omètre ( -o-, -meter )

Explanation

Want to keep track of how far you walk each day? You should get a pedometer, a portable device that measures every step you take. Break the word pedometer down into its roots and you get the Latin ped, or "foot," and the Greek metron, "a measure." That's exactly what a pedometer does: it measures each step your feet take. Most pedometers are small enough to carry with you while you walk, jog, or skip through your day, and they use the motion of your hand or hip to estimate how many steps you've taken.
