Shades of meaning
Usual (L. usus, use, habit, wont) signifies such as regularly or often recurs in the ordinary course of events, or is habitually repeated in the life of the same person. Ordinary (L. ordo, order) signifies according to an established order, hence of everyday occurrence. In strictness, common and general apply to the greater number of individuals in a class; but both words are in good use as applying to the greater number of instances in a series, so that it is possible to speak of one person's common practise or general custom, tho ordinary or usual would in such case be preferable. Compare general; normal.
