Nguyễn is a proper noun (Vietnamese surname) commonly anglicized as Nguyen. It denotes a family name and is widely associated with Vietnamese heritage; in Vietnamese, it is a single-syllable surname that presents a challenging, but learnable, combination of sounds for non-native speakers. The pronunciation combines a nasal onset, a mid front vowel, and a final, tightly produced glide, often requiring careful lip and tongue shaping to approximate the original tone and timbre.
