Word Origin & History
hornet
O.E. hyrnetu, hurnitu "large wasp, beetle," probably from P.Gmc. base *khurz-nut- (cf. Du. horzel "hornet"), from PIE imitative (buzzing) root *krs-, as preserved in O.C.S. srusa, Lith. szirszu "wasp." On this theory, the Eng. word (as well as Ger. Hornisse) was altered by influence of horn, to suggest either "horner" (from the sting) or "horn-blower" (from the buzz). Cf. also O.S. hornobero "hornet," lit. "trumpeter."
