"Someday you will have to sell this car."

Translation: Kiedyś będziecie musiały sprzedać ten samochód.

[lady-bug-tlen]

Kiedyś będziecie musieć sprzedać ten samochód - souds tottaly odd! should be: Kiedyś będziecie musieli sprzedać ten samochód.

[SpaceC]

Agreed

[manyclozel]

Why wouldn't this work?
"Kiedyś będziecie musiały ten samochód sprzedać"
Does it sound weird?

[Jellei]

It's possible, but it's not the usual word order. You rather put the verb first and then its object.

[stramner]

Is there a reason why musieć isn't accepted?

[Aldrost]

I think the first comments make this clear. For the "polish ears" two infinitives sound bad.
Not sure what happens if three are needed, though :) But perhaps in regular speech they aren't.

[dklaskowsk]

The singular form of you is not acceptable here? Kiedyś będzie musiał sprzedać ten samochód.

[Jellei]

Everything is fine with this sentence, but it's in 3rd person: "he will have to sell". You missed the -sz in "będziesz".

[Stewart288923]

I think there is a bug in this new 'fill in the gap' format. I wrote Kiedyś and checked several times!

[DMR680865]

Why not: Kiedyś będziesz musieli sprzedać ten samochód?

[chrgrv]

"będziesz" is 2nd person singular ... but "musieli" is plural ... so that doesn't fit together.
