"Ty hrady jsou velké."

Translation: Those castles are big.

[popxrebellion]

I get confused, doesn't "Ty" means "you"? Or it has two meaning..

[VladaFu]

Ty is either the singular of ty (you) or plural of ten (those)

[Branimir509848]

What is the difference between "Ty" and "Ti" - "ti muži / ty hrady" for example? And how do you know when to put letter "Y" at the end of the word?

[VladaFu]

See the Tips and notes, ti is for the masculine animate gender, ty is for masculine inanimate.

[Marko195]

Branimire, postoji razlika kako je češki saradnik Vlada objasnio.

U češkom je to drugačije nego u našem jeziku.

"Ti" se koristi samo za sve žive imenice muškog roda u množini, dok "Ty" za sve nežive imenice muškog roda kao što je "Hrady" (neživa imenica muškog roda u množini), ali i generalno (i nežive i žive) imenice ženskog roda u množini kao što su "Ženy" (živa imenica ženskog roda) i "Tabulky" (neživa imenica ženskog roda).

Pozdrav :)

Hvala na objašnjenju, Marko :)

Here we have "ty" versus a few challenges ago we had "to" for hrady (masculine). Also, why isn't the adjective velci' that I thought was a masculine adjective. I am really confused and making too many errors. Aiuta, per favore.

[BoneheadBass]

Please see my comment below regarding why velcí is not correct here.

I don't know what the other sentence was, but I would guess that it probably used the to jsou or jsou to construction. In those constructions, the to usually stands for "they" or "those"... but it does not directly modify a noun. Here, ty is a demonstrative pronoun modifying hrady, indicating that we're talking about some specific ("those") castles.

[PhoenixRising18]

Could I also translate this as "Those are big castles"?

[BoneheadBass]

That would be To jsou velké hrady. The course distinguishes between the two.

[WilliamM.G]

If castle is masculine inanimate, and Velky' hrad is a big castle, why is velci' hrady not correct?

[BoneheadBass]

That would be because velcí is used for masculine animate nouns. You can see the full declension at this handy site (click Show Declension) if the table isn't visible: https://en.wiktionary.org/wiki/velk%C3%BD.
