If Dictionaries are to be the Arbiters of language, in which of them shall we find Neologism. No matter. It is a good word, well sounding, obvious, and expresses an idea which would otherwise require circumlocution. ... I am a friend to Neology. It is the only way to give to a language copiousness and euphony. Without it we should still be held to the vocabulary of Alfred or of Ulphilas.
—Thomas Jefferson, American politician, statesman, and writer, letter to John Waldo, 1820
