Is it possible to say..?

[Teia]

Hi,

1. a 21-year -old man

2. a man of 21 [ years old]

Is the second sentence correct? If not, is there another formula I can possibly replace it with?



Thank you

Hi, Teia,
I think the second pattern is mostly used when the exact age is not known:
...a woman of 40
...a man of about 30
