"Your son drinks milk."

Translation: Dein Sohn trinkt Milch.

Can we use "eure" in place of dein?

[mizinamo]

Can we use "eure" in place of dein?

No, because Sohn is not feminine or plural, so eure with -e is not appropriate here.

You need euer Sohn.

Is it acceptable "Ihr Sohn..." if you are addressing the person formally?

[Lenkvist]

Yes, it is.

Can someone tell me why 'Ihre Sohn trinkt Milch', is wrong?

[mizinamo]

Can someone tell me why 'Ihre Sohn trinkt Milch', is wrong?

Ihre with its ending -e is used before a feminine or plural noun. (Those that take the article die or eine.)

But Sohn is masculine, not feminine or plural, so it would have to be Ihr Sohn. (No ending, like with ein Sohn.)

[eschlange]

Why isn't Ihre Sohn... an acceptable response?

[Lenkvist]

"Sohn" is a male word so you would use "Ihr Sohn".

[LuciBeachd]

I thought accusative make possessive was "deinen". Any thoughts?

[mizinamo]

I thought accusative make possessive was "deinen".

That is correct.

But dein Sohn is the subject of the verb trinkt and is, therefore, in the nominative case, not accusative.
