bivouac (English)
Where does "bivouac" come from?
The English noun 'bivouac' is an unadapted borrowing from French 'bivouac'[1], which evolved from earlier forms like 'biouac' and 'bivac'[1][2]. The French term ultimately derives from Alemannic German 'Biiwacht', meaning 'reinforcements of guard or town watch'[1] or 'a patrol of citizens added - in time of alarm or commotion - to the regular town watch'[2]. This Alemannic source is formed from the elements 'bii-' meaning 'by-' combined with 'Wacht' meaning 'watch, guard'[1][2].
