Translation:The grandparents have a small house.
I believe "The grandparents have a small home" would be correct as well?
No, that would be thuis, I think? Although, thuis may only work in an adverbial sense.
In any case, if you have a poky flat, you have a small 'home' but not a 'small house'.
I think "huis" refers specifically the type of home in an actual house, but I could be wrong.
One can indeed use het thuis as a noun. This is despite the fact that the word is merely a contraction of te huis.
Q : The robot pronounces the "s" like an "sh". Is it really like that in Dutch? Or does he try to make rather a "ss" sound?
I'm unaware, but good question! Its sad that they cant have a recording of a real human instead of questioning everything trying to comprehend microsoft sam.
