How to say "sir" in Japanese

Choosing the right word

卿きょうCommon
suffixHonorific, respectful (sonkeigo) language for 'Sir' in the sense of a lord's title; it also serves for 'Lord'. The nuance is deferential, befitting address or reference to a nobleman.
壁かべには、ピアノに向むかって座すわっているアンソニー卿きょうの大おおきな写真しゃしんがかかっていました。↗
On the wall there was a big picture of Sir Anthony at the piano.
サー
nounThe borrowed English word: 'Sir' as the Western honorific for knights, and 'sir' as a form of address in translated speech. It is the less common of the two, with a foreign flavour.
サー・ハロルドは立派りっぱな英国えいこく紳士しんしです。↗
Sir Harold is a fine English gentleman.

Both translate the honorific 'Sir': 卿 is respectful (sonkeigo) language for a lord or nobleman and also covers 'Lord', while 「サー」 is the borrowed Western title, the less common of the two.
