noun

reveille

REV-uh-lee/ˈrevəli/

A morning bugle call signaling soldiers to wake.

At dawn, reveille wakes the soldiers sleeping in their barracks.

At daybreak in a modern military barracks, a uniformed bugler plays beside an open doorway while two soldiers visibly wake in their bunks.
Etymology

The pieces combine “again” with “rouse.” The military noun turns the command “Awaken!” into the name of the morning signal that calls soldiers out of sleep.
