If you use a noun as an adjective, it must be singular
- You can say, “She is ten years old.” But if you use that phrase as an adjective, it becomes, “She is a ten-year-old girl.”
- The ceiling is ten feet high. The room has a ten-foot ceiling.
- My 16-year-old sister is so brilliant.
- A 45-year-old building
When speaking about age in English, we use the verb be (am, is, are) and not have/has.
- I’m thirty years old.
- My nephew is fourteen years old.
- These houses are 200 years old.
We can also say am / are / is + __(age)__ without “years old”:
- I’m thirty.
- My nephew is fourteen.
When it is somebody’s birthday, we say they turn __(age)__
- We threw a big party when my mother turned fifty.
- My youngest cousin just turned three.
