Etymology: Few English speakers would guess that a school's top pupil and a dukedom share a Latin ancestor. "Dux" is the Latin word for a leader, especially one who guides an army, and it comes from "ducere," meaning "to lead." That verb also gave English "duct" and "conduct." The same Latin noun, passed through Old French as "duc," produced "duke," so the two are close relatives that entered English by different routes. English has kept the word's core sense of leadership. In Scotland, Australia and New Zealand, the dux is the pupil who finishes first in a school year, a leader in the classroom rather than on the battlefield.
