Quoting: sparrow
It's on the same level as Polish & Slovak.
No no no :( It's not. Polish and Slovak are similar, Czech is similar on the grammatical level, tricky on the lexical (lotsa words which are written almost the same but mean a different thing, just to name jagoda = PL blueberry, jahoda = CZ strawberry), really challenging on the phonetical level. Pronunciation is a ***** (try this: Vlk škvrzl mrkl mrdl smrt frkl cvrkl krkl plkl prdl vrkl zblbl. Or this: Řežu a žeru, řežeš a žereš, žerou a řežou, žeru a řežu, žereš a řežeš, řežou a žerou. The "Ř" itself is often mispronounced even by the Czech themselves). If you still don't believe me, start learning - you'll be literally crying over an open textbook for the first 6 months :D
