Details of how to count in Vietnamese (tiếng việt / 㗂越),
an Austroasiatic language spoken mainly in Vietnam.
Two kinds of numbers are used in Vietnamese: Native Vietnamese
numbers, and Sino-Vietnamese numbers, which are borrowed from
Chinese and are not much used these days. The Native Vietnamese
numbers are written with the Quốc Ngữ
alphabet, and used to be written with the Chữ Nôm
script, and the Sino-Vietnamese numbers are written with either
the Quốc Ngữ alphabet or the Hán
tự script (Chinese characters).
