English[edit]

Etymology[edit]

Diagram showing the relationship between the zenith, the nadir, and different types of horizon. Note that the zenith is opposite the nadir.

From Middle English cenyth, from Medieval Latin cenit, from Arabic سَمْت(samt, direction, path), from the fuller form سَمْت اَلرَّأْس(samt ar-raʾs, 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.
