An old or gray cat, or a cat-like creature; sometimes used in witchcraft folklore to refer to a familiar spirit.
From Middle English, combining gray with malkin (an old word for cat, derived from the name Maud/Matilda). The term appears in Shakespeare and other Renaissance literature referring to supernatural cats.
Shakespeare mentions 'Graymalkin' in Macbeth as one of the witches' familiars, and this single word has kept the term alive for over 400 years in English literature and fantasy!
