German grammar question - familiar plural
Hello. I'm hoping someone can help with this.
My question is if you have a compound subject of two familiar people, do you use the familiar form or not?
That is, would a mother say to her son Du und Dein Vater kommt (like ihr kommt)? Or Du und Dein Vater kommen (like Sie Kommen)?
It is actually a bit tricky, I think. The construction includes "you", so I think it might depend on the context. I would probably add the pronoun here to make it clear: if you are adressing the person "you" directly, I would say "Du und dein Vater, ihr kommt", e.g. in a question like "Du und dein Vater, kommt ihr nach Hause?" or "Du und dein Vater, ihr kommt doch, oder?". To me as a native speaker, that would sound perfectly natural. On the other hand side, if you are not adressing the "you" directly in a question or so, I think you would say - for example - "Du und dein Vater kommen zum Essen." (Although "Du und dein Vater, ihr kommt zum Essen" sounds right too.)
I am not entirely sure about this on a strictly grammatical level, but this is what I would say and what would sound natural to me.
