Etymology

From Middle English cenyth, from Medieval Latin cenit, from Arabic ?????? (samt, “direction, path”), from the fuller form ????? ?????????? (samt ar-ra?s, “direction of the head”). The -ni- for -m- is sometimes thought to be due to a misreading of the three strokes, which is plausible, though it could be a mere phonetic approximation.
