Sir

Latin, senex; Spanish, señor; Italian, signor; French, sieur; Norman, sire; English, sir. According to some, Greek αναξ is connected with Sir; on the analogy of εμ-μι (ειμι) = Latin sum; αμπερεζ = Latin semper; oπoζ = Latin sapa.

Sir (a clerical address). Clergymen had at one time Sir prefixed to their name. This is not the Sir of knighthood, but merely a translation of the university word domĭnus given to graduates, as “Dominus Hugh Evans,” etc.
