In Judaism, a rabbi is a teacher of Torah. This title, pronounced in English, derives from a Hebrew word meaning "My Master", which is the way a student would address a master of Tora. This word "master" literally means "great one" or one who is "abundant/much/many”. The basic form of the rabbi developed in the Pharisaic and Talmudic era, when learned teachers assembled to codify Judaism's written and oral laws.
