Romania

noun and adjective, Old English, "of or pertaining to ancient Rome; an inhabitant or native of ancient Rome," from Latin Romanus "of Rome, Roman," from Roma "Rome" (see Rome). The adjective is c. 1300, from Old French Romain. The Old English adjective was romanisc, which yielded Middle English Romanisshe.

The Roman nose, having a prominent upper part, is so called by 1620s. The Roman candle as a type of fireworks is recorded from 1834. Roman Catholic is attested from c. 1600, a conciliatory formation from the time of the Spanish Match, replacing Romanist, Romish which by that time had the taint of insult in Protestant England.
