Chữ Quốc ngữ

Creation of chữ Quốc ngữ

As early as 1620, with the work of Francisco de Pina, Portuguese and Italian Jesuit missionaries in Vietnam began using Latin script to transcribe the Vietnamese language as an assistance for learning the language. The work was continued by the Avignonese Alexandre de Rhodes. Building on previous dictionaries by Gaspar do Amaral and António Barbosa, Rhodes compiled the Dictionarium Annamiticum Lusitanum et Latinum, a Vietnamese–Portuguese–Latin dictionary, which was later printed in Rome in 1651, using their spelling system. These efforts led eventually to the development of the present Vietnamese alphabet. For 200 years, chữ Quốc ngữ was used within the Catholic community. However, works written in the Vietnamese alphabet saw limited use, while Catholic texts in chữ Nôm were significantly more widespread. Chữ Nôm thus remained the principal writing system used by Vietnamese Catholics during this period.
