Ines (Inés in Spanish, Inês in Portuguese) is the Spanish and Portuguese form of Agnes — from the Greek hagnē (ἁγνή), meaning "pure" or "holy." Saint Agnes of Rome was an early Christian martyr.
Ines is one of the most popular girl's names across the Spanish- and Portuguese-speaking world. The medieval Inês de Castro (1320-1355), the Portuguese queen consort posthumously crowned, is one of the most famous bearers — her story has inspired plays, operas, and poems for seven centuries.
Ines reduces to three — the number of pure brightness.
