What does constable mean?
A constable is a police officer holding the lowest commissioned rank in many forces, most familiarly in the United Kingdom and Commonwealth countries, where 'PC' (police constable) is a routine part of public life. In parts of the United States, by contrast, a constable is usually an elected county officer who performs limited legal duties such as serving subpoenas and acting as a bailiff. The word also has a distinguished historical sense: in medieval England and France the Lord High Constable was one of the great officers of state, originally a master of horse. Derived from the Latin 'comes stabuli', meaning 'count of the stable', the term travelled from supervising stables to commanding armies and finally to ordinary street-level policing. Today the word carries a mildly formal, institutional tone in Britain, while in America it evokes small-town or county government. Related forms include constabulary, describing a police force collectively.
A police officer of the lowest rank in many forces, especially in the United Kingdom; also an official charged with minor peacekeeping or judicial duties at local level.
"Constable Patel radioed for backup before approaching the vehicle."
In British English, 'constable' is used as part of a police officer's formal form of address, prefixed directly to their name.
(Historical) A high officer of a royal household or army having command over cavalry and matters of chivalry, as in the medieval title Lord High Constable.
"In twelfth-century England, the Lord High Constable ranked among the greatest officers of the crown."
This sense is now obsolete except in ceremonial titles and heraldic contexts.
Standard plural; no irregularities.
"Two constables were dispatched to the scene within minutes."
The word 'constable' comes from Latin 'comes stabuli' — literally 'count of the stable' — meaning the medieval officer who looked after a lord's horses rose to keep the king's peace.

Etymology of constable
The word 'constable' derives from Old French 'conestable', borrowed from Latin 'comes stabuli', literally 'count of the stable', an officer in the late Roman Empire responsible for the emperor's horses. Through the Frankish kingdoms the role evolved into a high military command — hence the Lord High Constable of England and France in the Middle Ages. By around the thirteenth century the term had come down in scale to mean a local officer appointed to keep the peace, and eventually settled into its modern senses as a low-ranking police officer or a minor county official. Cognates appear across European languages via the same Latin source.

How constable is actually used
In British English, 'constable' specifically denotes the rank below sergeant, so it functions much like a surname-prefix in formal address ('Constable Smith'). In American usage the word more often refers to an elected county officer rather than a rank. The historical military sense survives only in archaic titles and should not be assumed in modern reading.
