Word Origin & History
falcon
c.1250, from O.Fr. faucon, from L.L. falconem (nom. falco), probably from L. falx (gen. falcis) "sickle," usually said to be so called for the shape of its talons or beak, but possibly from the shape of its spread wings. The other theory is that falx is of Gmc. origin, which is supported by the antiquity of the word in Gmc. but opposed by those who point out that falconry by all evidences was imported from the East, and the Germans got it from the Romans, not the other way around.
