ped-, pedi-, -pedal, -ped, -pede, -pedia
(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.)
Keep in mind that all of the ped words which you see in English are not always from the Latin "foot" or "feet". There are also some Greek ped words in English which do not mean "foot"! So, don't confuse this Latin element with a Greek pedo- that means "child" or the Greek pedo- which means "ground, soil".
If you want to leave footprints in the sands of time, don’t drag your feet.
