nonordinary

The word 'nonordinary' is a modern English compound formed by directly applying the Latinate negative prefix 'non-' to the existing adjective 'ordinary'. 'Ordinary' itself entered English from Anglo-Norman 'ordenarie', derived from Latin 'ordinarius', meaning "according to order, regular, usual," from 'ordo' (genitive 'ordinis'), meaning "row, series, arrangement." The PIE root is likely h₂er- ("to fit together"). Therefore, the literal construction "not according to the usual order" logically yields the modern abstract sense of "unusual" or "atypical," describing something that deviates from the standard or expected arrangement.

Structure: non (not) + ordinary (usual) - non: A prefix of Latin origin, meaning "not." It functions as a negative or privative prefix. - ordinary: An adjective of Latin origin (via Anglo-Norman and French), meaning "usual, regular, or customary." It functions as the base word being negated.
