Etymology
Origin of gnat
before 900; Middle English; Old English gnæt ( t ); cognate with German (dial.) Gnatze
Explanation
Those tiny black insects swarming around your head just as the sun goes down are probably gnats, very small flies that are extremely annoying but usually don't bite. If those little flying creatures bite you, they're most likely mosquitoes. If they just irritate you, landing on your face and creating a cloud around your head? They're gnats. Although the word comes from a Germanic root related to gnaw and meaning "biting insect," the truth is most gnats just want to fly around, eat plants, and mate. Occasionally they're attracted to the fluids in your eyes, which means you'll have to swat them away.
