(Greek: melos, limb, body extremity or member; a condition of the limbs or extremities of a body; such as, arms, hands, fingers, legs, feet, toes, etc.)

(Latin: foot, feet; people often see this ped element in other words. When people refer to "pedal extremities", they mean "feet". When anyone pushes the pedals of a bicycle, it is done with the feet. A pedestrian must use the feet for walking. A quadruped has four feet while a centipede has "100 feet"; or a large number of them because it may be impossible to count all of them.)
