In ancient Rome, contrasted with the plebeius (see plebeian). In post-classical times, applied to noble citizens and higher orders of free folk in medieval Italian and German cities (a sense attested in English from 1610s); hence "nobleman, aristocrat" in a modern sense (1630s). As an adjective, attested from 1610s, from the noun. Related: Patricianism.
