An Etymological Dictionary of the German Language/Annotated/None

by Friedrich Kluge

None, feminine, ‘afternoon prayers,’ from Middle High German nône, Old High German nôna, feminine, ‘hora nôna, the ninth hour of the day’ (reckoned from six A.M.), also ‘the prayers said at that hour.’ The term was borrowed during the Old High German period from Latin nôna (scil. hora; compare French none, Italian nona); compare also Old Saxon nôna, nôn, Anglo-Saxon nôn, English noon (the difference in time is said to be due to the shifting of the canonical ‘nona’ to midday).
