Title of honor or respect
Derived from the Middle English 'sire', which evolved from the Old French 'sieur', ultimately from the Latin 'senior' meaning older or elder. It has historically been used as a formal address for men and a title for those knighted by a monarch. In recent years, it has transitioned from a title to a given name, popularized by high-profile celebrity usage.
