The falcon probably takes its name from the “sickle” shape of its beak, talons, or wings.
This Sunday, the Atlanta Falcons will take on the New England Patriots in Super Bowl LI in Houston, Texas. I’ve previously taken on the etymology of patriot, which ultimately derives from the Greek word for “father” and, curiously, didn’t always carry a positive connotation in English. But what the origin of the word falcon?
A bird, or sickle, in the hand…
Falcon stooped on English in the mid 1200s. The Oxford English Dictionary firsts falcon, as faukun, in The Owl and the Nightingale, dated to around 1250. In this poem, the titular birds sharply debate which of them is the superior avian. (The nightingale accuses the owl of laying an egg in a falcon’s nest, the medieval version of Deflategate, I suppose.)
The English falcon swoops in from the Old French faucon, which flies from the Late Latin falcōnem, all referring to the bird of prey. The nominative, or subject case, form of falcōnem was falcō, presumably derived from falx, “a sickle.” The falcon’s beak, talons, or possibly the sharp curve of its outspread wings resemble this farming blade, apparently.
Falx also gives English falcate, “curved like a sickle,” falchion, a machete-like sword, and, speaking big names of the US South, the surname Faulkner (“falconer”).
