In the usual or normal course of events; typically or commonly.
From Latin ordinarius meaning 'regular' or 'usual,' derived from ordo (order, rank). The word entered English in the 14th century through Old French ordinarie, with the adverbial suffix -ly added to indicate manner.
The word 'ordinary' originally referred to things that were 'in order' or properly arranged, which is why we still use 'ordination' for organizing clergy and 'coordination' for organizing activities. What we consider 'ordinary' today would have been extraordinary to people just a century ago - like having instant global communication in our pockets.
