"large basket," early 14c., hampyre, probably a contraction of Anglo-French hanaper (Anglo-Latin hanepario), from Old French hanepier "case for holding a large goblet or cup;" in medical use "skull," also "helmet; armored leather cap," from hanap "goblet, chalice," from Frankish or some other Germanic source (cognates: Old Saxon hnapp "cup, bowl;" Old High German hnapf, German Napf, Old English hnæpp). The first -a- may be a French attempt to render Germanic hn- into an acceptable Romanic form. The English word also meant "the department of Chancery into which fees were paid for sealing and enrolling charters, etc." (15c.).
