bivouac (English)

Where does "bivouac" come from?

The word 'bivouac' originated from the Alemannic German 'Biiwacht,' a term for extra town guards called to duty during emergencies. It migrated into French as 'bivouac,' where it shifted from describing a defensive watch to a temporary night encampment. English adopted the term directly from French, eventually expanding its meaning to include outdoor shelters and even natural structures built by insects.
