"Ti psi jsou velcí."

Translation: Those dogs are big.

[Giiang]

what's the difference between vidím "ty psy" and "ti psy"?

[VladaFu]

ti psi is the nominative case
ty psy is the accusative case
ti psy is just wrong

Please read the Tips and notes.

[Bohemice]

If I have understood correctly, there is a difference of pronunciation between ti and ty (the first one is palatalized) but I guess there is no difference between psi and psy, right? Thanks.

Why the male animate nominative plural is used here for dogs? Are they not neuter?

[JanLyko]

They ARE masculine (TEN pes) animate, pattern "pán"

Why not "The dogs are big"?

[VladaFu]

That is also accepted.

[Keag]

Why not These dogs are big? How would you say that in Czech?
