An Etymological Dictionary of the German Language/Hose
Hose, f., ‘hose, stocking, breeches,’ from the equiv. MidHG. hose, OHG. hosa, f.; comp. AS. hosu, E. hose, and the equiv. OIc. hosa; Goth. *hŭsô is by chance not recorded. ‘Hose’ was originally (in OHG., MidHG., AS., and OIc.) applied to a covering for the legs reaching from the thigh, or even from the knee only, and often also to stockings and gaiters. Considering the numerous correspondences in Kelt. and Rom. the Teut. term is certainly original; the Teut. words found their way into Kelt. (Corn. hos, ‘ocrea’), and Rom. (OFr. hose). The connection of Hose with OSlov. košulja, f., ‘shirt,’ is dubious.
