"Our door is always open."

Translation: Naše dveře jsou vždy otevřené.

[ErikJRodgers]

Our door is singular (in English). Is it generally pluralized in Czech?

[VladaFu]

yes

[JesperJons]

I wonder why our door, singular in English, is translated to plural in Czeck?

[VladaFu]

It is like trousers or scissors, it is always plural.

[walkinwolk]

I used "vždycky" instead of "vyždy". Why was this wrong?

[BoneheadBass]
