It is standard among Jews writing in Hebrew to attach the honorific כמר before introducing one's name. This custom is actually quite old dating back at least to the days of the earliest Acharonim, and possibly even earlier than that. But does anyone know what it means? This word has always baffled me. מר in Aramaic means "Lord" (or the English Mister), but why is there the letter כ in the beginning? A literal translation in Aramaic would yield "like the lord", which really makes no sense as an honorific or title. Any insight?
I always understood that the word "Mar" was used in the Talmud to refer to someone on the caliber of Rav (see article above) and later generations used the word "Kemar" meaning "like a Mar" but not exactly a Mar since that's reserved for earlier generations.
Just a thought.
