Age with "sui"


Use 岁 (suì) to tell someone your age. The sentence pattern is a bit different from English, however.


The structure for telling someone's age with 岁 (suì) is:

Subj. + Num. + 岁

This is equivalent to someone "is x years old" in English.


  • 我 20 Wǒ èrshí suì.I am 20 years old.
  • 我 妈妈 今年 45 Wǒ māma jīnnián sìshí-wǔ suì.My mother is 45 years old this year.
  • 我 儿子 一 半。Wǒ érzi yī suì bàn.My child is one and a half years old.
  • 你 爷爷 今年 80 吗?Nǐ yéye jīnnián bāshísuì吗?Is your grandpa eighty years old this year?
  • 他 女朋友 也 20 吗?Tā nǚpéngyou yěsuìma?Is his girlfriend also twenty years old?

Note that you don't need the verb (shì) in any of these sentences, and you don't need a measure word like (gè) either. In fact, it would be incorrect to use either of those with 岁 (suì):

  • 我 的 孩子 一 Wǒ de háizi yī suì.
  • 我 的 孩子 Wǒ de háizi shìsuì.
  • 我 的 孩子 一 Wǒ de háizi yī suì.My child is one year old.
