Thi
Meaning
from a Chinese character meaning clan, lineage; written Thị. The traditional feminine middle name: for generations nearly every Vietnamese woman's legal name carried it (Nguyễn Thị Mai), and refugee-era US paperwork often fused it into the first name, which is why so many Vietnamese American women have Thi on their documents. Parents today mostly skip it in favor of meaningful two-part given names, making Thị itself a generational marker
Popularity, 1890–2024
