Calʹiban
.Rude, uncouth, unknown; as a Caliban style, a Caliban language. The allusion is to Shakespeare’s Caliban (The Tempest), in which character Lord Falkland, etc., said that Shakespeare had not only invented a new creation, but also a new language.
“Satan had not the privilege, as Caliban, to use new phrases, and diction unknown.”—Dr. Bentley.
Coleridge says, “In him [Caliban, as in some brute animals, this advance to the intellectual faculties, without the moral sense, is marked by the appearance of vice.”
(Caliban is the “missing link” between brute animals and man.)
