Thuy is most commonly a female name in Vietnamese usage, where it is written with the character 翠 meaning "jade" or "green." In Vietnam, Thuy (sometimes spelled Thủy) is used primarily for women and appears in full names such as Nguyễn Thùy or Trần Thị Thùy. Outside Vietnam, perceptions can differ; in some Western contexts the name may be given to any gender or treated as short for names like Thuyền. Status and recognition depend on community, transliteration, and personal experience. This explainer summarizes current naming patterns and linguistic context without asserting a single universal rule.
