Non-Sino-Vietnamese reading of Chinese 子 (SV: tử). Some dictionaries (such as Thiều Chửu's) consider it as Sino-Vietnamese, but the sắc tone in Tí is unlikely to be derived from the Middle Chinese rising tone, compared to the likely hỏi tone in tử. See also Mẹo, Thìn, Mùi.
- This is not a "diminutive" name. The legal name of the person who bears this nickname usually has nothing to do with it, semantically or phonetically.
