Definitions

1. A Latin term referring to a foot, often used in anatomical or zoological contexts
2. the base unit of length in the imperial system consisting of twelve inches
3. a measure of distance that includes variations across different cultures and historical periods

Etymology: The Latin "pes" (genitive "pedis") meant "foot" and gave English words like "pedal", "pedestrian" and "pedestal". As a unit of measure, it was the Roman foot, a length close to 29.6 centimetres, roughly 11.65 inches. The Romans defined it as one sixteenth of the "passus", the double pace, and a thousand paces made a "mille passus", the origin of the mile. Because the foot was tied to the human body, the unit spread widely across the Roman world and survived long after the empire fell. Measures modelled on it persisted in parts of Europe into the modern period, which is why the same basic length appears under different local names in many old systems. Its connection to the body is also why the Latin noun for the unit has the same form as the everyday word for foot.
