"pertaining to or having the character of crows and ravens," 1650s, from Latin corvinus "of or pertaining to the raven," from corvus "a raven," related to corax (Greek korax), all imitative of its harsh sound (see raven (n.)). According to fable, originally white but changed to black as a punishment for treachery, but the bird also was consecrated to Apollo for its supposed power of prophecy.
