About Czech
Czech is spoken by about 10.7 million people and is the official language of the Czech Republic. It is a West Slavic language known for its complex consonant clusters and seven grammatical cases.
Who is this app for? Travelers to Czech Republic and Prague, Czech learners, students, expats.
Words without vowels
Czech permits consonant clusters that look impossible to an English eye. The standard demonstration is strč prst skrz krk — "stick a finger through your throat" — a complete sentence with no vowel letters at all.
It works because r and l can act as syllable nuclei in Czech, carrying a syllable the way a vowel does in English. Vlk (wolf) and krk (neck) are ordinary one-syllable words. Once you accept that r and l can be syllables, the clusters stop being unpronounceable.
The letter no other language has
Czech ř is a genuinely unusual sound — a trilled r produced with friction, simultaneously rolled and buzzed. It appears in the composer's name Dvořák and in the word for river, řeka. Czech children take longer to acquire it than any other sound in the language, and adult learners often settle for an approximation. That is a reasonable compromise; it rarely blocks understanding.
Stress and length are independent
Czech stress falls on the first syllable of a word. Always. That is one thing you never have to look up.
Vowel length, marked with an acute accent (á é í ó ú ý), is separate from stress and distinguishes words. So a long vowel in the second syllable is still unstressed but still long — a combination English speakers find genuinely difficult, since English ties length and stress together.
Beyond that: seven cases, three genders, and verbal aspect pairs. Czech is spoken by around ten million people and is the official language of the Czech Republic.
Frequently Asked Questions
How can Czech words have no vowels?
Because r and l can function as syllable nuclei, carrying a syllable the way a vowel does in English. Vlk (wolf) and krk (neck) are ordinary one-syllable words, and strč prst skrz krk is a complete sentence with no vowel letters.
What is the ř sound?
A trilled r produced with friction at the same time — rolled and buzzed together. It occurs in Dvořák and in řeka (river). It is the last sound Czech children acquire, and adult learners commonly approximate it without losing comprehensibility.
Where does the stress fall in Czech words?
Always on the first syllable, without exception. Vowel length is marked separately with an acute accent and is independent of stress, so an unstressed syllable can still carry a long vowel.
