SIR definition: a respectful or formal term of address used to a man. See examples of sir used in a sentence.
Sir is a formal honorific address in English for men, derived from Sire in the High Middle Ages. Both are derived from the old French " Sieur " (Lord), brought to England by the French-speaking Normans, and which now exists in French only as part of "Monsieur" lit. 'my lord'.
Sir is used at the beginning of a formal letter to a man you do not know: Dear Sir
People sometimes say sir as a very formal and polite way of addressing a man whose name they do not know or a man of superior rank. For example, a shop assistant might address a male customer as sir.
- a polite form of address (spoken or written) to a man. Excuse me, sir!; He started his letter `Dear Sirs, ...'.
