Don't Leave Without the History of Exodos

The Biblical book of Exodus describes the departure of the Israelites from Egypt, so it's no surprise that the word has come to refer more generally to any mass departure. The word itself was adopted into English (via Latin) from Greek Exodos, which literally means "the road out." The Greek word was formed by combining the prefix ex- (meaning "out of") and hodos, "road" or "way." Other descendants of the prolific hodos in English include episode, method, odometer, and period. There are also several scientific words that can be traced back to hodos. Anode, and cathode can refer, respectively, to the positive and negative electrodes of a diode, and hodoscope refers to an instrument for tracing the paths of ionizing particles.
