The language spoken in the Czech Republic is Czech, the sole official language, used by virtually all of the country's roughly 10.7 million inhabitants. Czech (called cestina by native speakers) is a West Slavic language written in the Latin alphabet, and it functions as the language of government, education, media, and everyday life across both the Bohemian and Moravian regions of the country.
Czech: The Official and Everyday Language
Czech belongs to the West Slavic branch of the Indo-European family, placing it alongside Slovak and Polish. It is spoken natively by the overwhelming majority of the population and serves as the country's only official language at the national level. You will hear it everywhere, from the metro announcements in Prague to village shops in the Moravian countryside.
The modern standard form of Czech emerged from a remarkable national revival. After centuries of Habsburg rule, during which German dominated administration, commerce, and higher learning, Czech had been pushed toward the margins of public life. In the late 18th and 19th centuries, a generation of scholars and writers deliberately revived, standardized, and expanded the language, turning it into a powerful symbol of Czech national identity that eventually underpinned the creation of an independent state.
How Czech Sounds and Is Written
Czech uses the Latin alphabet enriched with diacritical marks: the hacek (caron) and the acute accent that marks long vowels. These marks let the writing system represent sounds that plain Latin letters cannot. The most celebrated example is the letter "r" with a hacek, a sound that combines a rolled R with a buzzing "zh" quality and is widely described as unique to Czech. It famously appears in the surname of composer Antonin Dvorak, which non-Czechs almost universally mispronounce.
Another hallmark of Czech is its tolerance for long consonant clusters and syllabic consonants, where letters like "r" and "l" can carry a syllable on their own. The classic tongue-twister Strc prst skrz krk ("stick a finger through your throat") contains no vowels at all, yet is a perfectly grammatical Czech sentence. Stress in Czech is predictable and always falls on the first syllable of a word, which gives the language a steady, even rhythm once your ear adjusts.
Dialects and the Link to Slovak
Within the country, linguists recognize several dialect groups. Bohemian dialects dominate the central and western regions and form the basis of standard literary Czech, while Moravian dialects cover the east and Silesian varieties appear in the northeast. As you travel eastward, Moravian speech gradually shades into Slovak along the border.
That blending reflects the exceptionally close relationship between Czech and Slovak. The two languages are highly mutually intelligible, so a Czech speaker and a Slovak speaker can generally follow one another without any formal study. This shared understanding is a legacy of the decades the two peoples spent together in Czechoslovakia, which split peacefully into the Czech Republic and Slovakia in the "Velvet Divorce" of 1993.

Other Languages You Will Encounter
While Czech is universal, the Czech Republic is far from monolingual in practice. Slovak is widely understood and frequently heard, and there are small communities speaking Polish, German, and Romani, particularly near borders and in regions with historical minority populations. Vietnamese and Ukrainian are also spoken by sizeable immigrant communities in the larger cities.
For international visitors, English is the most useful second language. It is commonly spoken in Prague, tourist districts, hotels, and among younger Czechs, while German remains valuable thanks to geographic proximity and economic ties with neighboring Austria and Germany. In smaller towns and rural areas, however, knowledge of foreign languages drops off quickly, so a few Czech phrases go a long way.
Handy Czech Phrases for Travelers
A little effort with the local language is genuinely appreciated. Some essentials include:
- Dobry den — good day / hello (formal)
- Dekuji — thank you
- Prosim — please / you're welcome
- Ano / Ne — yes / no
- Kolik to stoji? — How much does it cost?
- Mluvite anglicky? — Do you speak English?
- Pomoc! — Help!
Even a confident Dobry den on entering a shop, a custom many Czechs observe, will mark you as a thoughtful guest rather than a hurried tourist.
Frequently Asked Questions
Is Czech the same as Slovak?
No, they are separate languages, but they are very closely related and largely mutually intelligible. Czech and Slovak speakers can usually understand each other in conversation, a result of the two peoples sharing a country as Czechoslovakia until 1993.
Is English widely spoken in the Czech Republic?
English is common in Prague, tourist areas, hotels, and among younger people. In smaller towns and rural regions it is much less reliable, so learning a handful of Czech phrases is helpful when traveling beyond the main destinations.
Why is Czech considered hard to pronounce?
Czech features long consonant clusters, syllabic consonants, and the rare "r" sound (a rolled R blended with a "zh"). Sentences such as Strc prst skrz krk contain no vowels at all, which makes the language notoriously tricky for newcomers.
What alphabet does Czech use?
Czech uses the Latin alphabet supplemented with diacritics: the hacek (caron) and the acute accent for long vowels. These marks allow the writing system to capture sounds that standard Latin letters cannot represent on their own.
