Etymology
Origin of hornet
First recorded before 900; Middle English harnete, Old English hyrnet(u); cognate with Old High German hornaz (becoming German Horniss ); akin to horn
Explanation
A hornet is a flying, buzzing insect with a painful sting. Much larger than bees, hornets look very similar to yellow jackets. Etymologists suspect that hornet comes from an imitative root word (one that resembled a hornet's buzz) combined with horn, from the insect's horn-like stinger. This large wasp builds papery nests and lives in social groups like bees, with dominant queens. Hornets only sting if they're provoked — or if they think their nests are being threatened. Some people are dangerously allergic to their venom, and even without an allergy, you won't enjoy being stung by a hornet.
