Sire

Sire is an English word historically used when addressing a king. It can also refer to a father, especially in descriptions of animal parentage. Those established meanings give the name a title and ancestry association, but “royalty” is an interpretation of its use rather than a separate literal definition.

As a personal name, Sire belongs alongside modern choices taken from titles and forms of address. Musician Usher's son Sire is one public example. Sire should be distinguished from Sir: they are related-looking English words but are not pronounced identically in ordinary use. A family considering it can weigh both the royal address and the parentage meaning rather than seeing only one side of the word.
