Etymology
The word reveille entered English in the 17th century from the French imperative phrase réveillez, meaning "wake up," itself derived from the verb réveiller (to awaken). This French verb originates from the Vulgar Latin revegiliare, a compound of the Latin prefix re- (again) and vigilare (to be awake, to watch). The core Latin root vigil points to a state of alertness and wakefulness. Thus, the literal command "wake up again" evolved through military usage into the specific term for the morning wake-up call, perfectly capturing its function to rouse soldiers from sleep at the start of the day.
