"Slovensko soused Německa není."

Translation: Slovakia is not Germany's neighbor.

[HelgaPass]

why not: slovakia isnt neighbour of germany?

You need an article before neighbour.

why nemecka here?

[BoneheadBass]

Another way to read the sentence is "Slovakia is not a neighbor OF Germany." So we have "Německa" (genitive) instead of "Německo" (nominative).

Why can't it be 'Germany is not Slovakia's neighbor?

[VladaFu]

Because it is s different sentence. It is about what Germany is or isn't while the original is about Slovakia.
