Word History
The English word alert comes from a l'erte, an early French phrase that means "on guard" or "on the watch." This French phrase came from an Italian military phrase, all'erta. Erta means "a high or raised place," such as a hilltop or tower soldiers might use to see the enemy coming from a distance. All'erta meant "standing on the high tower."
