"Our house is pretty" doesn't match?
We do not consider "pretty" strong enough for "piękny".
So what would "pretty" be in this case? Śliczny?
Just „ładny”. „Śliczny” is comparable to „piękny”, but I find it somewhat infantile.
What case is piȩkny in?
It's simply Nominative.
Is attractive beautiful? I wonder what Socrates would ask about this.
Could this be used the same way as ślicznie
"ślicznie" is an adverb, and the adjective "śliczny" is not strong enough for "beautiful".
Is 'our home is beautiful' no good?
It should have worked, as it's an accepted answer.
It is problem because our must br with '' are''
what
"Our house" is undoubtedly singular. "Our house is".
