"This is only for us."

Translation: Das ist nur für uns.

Why not Diese ist nur fur uns?

[Kathi403348]

you would actually say: "Dies ist nur für uns." but that sounds way too fancy, nobody would say that!
but have a look at what I commented in this thread, maybe that helps, too: https://www.duolingo.com/comment/25229053

The word list showing 'for us' is 'uns' not ' fur uns'.

Why "nur" and not "einfach"?

[mizinamo]

nur means "only"

einfach means "simply"

Perhaps you're confused because "just" can cover both meanings? (It's just a mouse = It's only a mouse; That's just the way it is = That's simply the way it is.)

Why is "Dieses" wrong? I don't get it.
My first answer was: "Dieses ist nur für uns", and it was taken for a wrong answer.

I'm still never clear on which or how many situations you can use "Das" but it seems to be incredibly never-ending and flexible.
