How to Say "Six" in Vietnamese

sáu

[saw˧˦]

The Vietnamese word for six is sáu. It is the number that comes after five and before seven.

sáu is used for counting, for doing sums and for saying how many things there are.

Meaning: cardinal number (num)

How does it change in a sentence?

sáu goes before the noun it counts, as in sáu phòng, six rooms. The noun does not change for plural.

Keep the rising tone mark on sáu. Without it the word can be read as a different word.

In Vietnamese, the number sáu is considered lucky because it sounds like the word for 'flow' or 'smooth', suggesting that things will progress without obstacles.
The word sáu is a distant relative of the word 'hynriew' used for 'six' in Khasi, a language spoken in the Meghalaya state of India.
