How Vietnamese names are chosen

A Vietnamese name runs family name, middle name, given name — and the middle element, the tên đệm, does work that most naming systems have no slot for. It once mainly marked gender, Văn for a son and Thị for a daughter, a convention now widely felt to be dated. Modern parents use the position for meaning instead, often carrying the mother's family name or a word chosen to complete the given name into a phrase. Some families run it as a generational marker, with all siblings sharing one middle name; others give the same middle name to everyone of one gender across generations.

Vietnamese is tonal and its diacritics are load-bearing: strip the accents, as English forms usually do, and distinct names become indistinguishable.
