Where does the word "constable" come from? It comes from Late Latin comes stabuli, passing through Old French before entering English (1200s).
Constable’s story begins in Late Latin: comes stabuli meant “master of the horse.” 'count of the stable', the officer in charge of the imperial, and later Frankish royal, horses. By 1100s, the word had taken hold in Old French as conestable. Rose to become commander of the French army; Bertrand du Guesclin was made Constable of France in 1370. It reached English by 1200s as constable. From castle-keeper down to village officer; Robert Peel's police of 1829 made it the basic police rank. Today, constable means a police officer of the lowest rank.
