Sire
For other uses, see Sire (disambiguation).
Sire is a form of address for reigning kings in the United Kingdom and in Belgium. It was formerly also used in France, Italy, Germany, Portugal, Sweden and Spain. Historically Sire had a wider usage. During the Middle Ages, Sire was generally used to address a superior, a person of importance or in a position of authority or the nobility in general. The word "sire" and the French "(mon)sieur" share a common etymologic origin, both ultimately being related to the Latin senior.
