Pointing

Middle English: the noun partly from Old French point, from Latin punctum ‘something that is pricked’, giving rise to the senses ‘unit, mark, point in space or time’; partly from Old French pointe, from Latin puncta ‘pricking’, giving rise to the senses ‘sharp tip, promontory’. The verb is from Old French pointer, and in some senses from the English noun.
