Age with "sui"

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

Structure

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.

Examples

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

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

• 我 的 孩子 一 个 岁 。Wǒ de háizi yī gè suì.
• 我 的 孩子 是 一 岁 。Wǒ de háizi shì yī suì.
• 我 的 孩子 一 岁 。Wǒ de háizi yī suì.My child is one year old.

• Word order
• Simple "noun + adjective" sentences
