Quốc Ngữ is the modern writing system used for the Vietnamese language. It was developed in the 17th century by Christian missionaries, particularly Alexander de Rhodes, who aimed to create a simpler way for people to read and write. This system uses the Latin alphabet, making it easier for Vietnamese speakers to learn compared to the traditional Hán-Nôm script, which was more complex. Today, Quốc Ngữ is the official script of Vietnam and is used in education, media, and everyday communication. Its adoption has played a significant role in increasing literacy rates and promoting the Vietnamese culture and identity, allowing for greater access to information and education.
