Is it correct to say ho 25 or sono in Italian?

You are close, but the correct way to say "I am 25" in Italian is:

"Ho 25 anni"

* Ho: I have

* 25: Twenty-five

* anni: years

Sono means "I am" and is used for stating your age in Italian. However, it's followed by a specific age, not just a number. For example:

* "Sono vent'anni" (I am twenty years old)

* "Sono trentacinque anni" (I am thirty-five years old)

Let me know if you have any other questions!
