What language is spoken in Czechia? Czech, plus English and Slovak

In a café in Vinohrady, English works perfectly well. At a post office, a tax office or a doctor's surgery in a smaller town, it often does not. Both experiences are normal, and the gap between them is what a newcomer should plan for.

The short answer

The language of Czechia is Czech (čeština). It is the only official language of the state, the language of the Constitution, of the courts, of the schools and of almost every public service. The large majority of residents use it as their first language, and the Czech Statistical Office publishes the exact share from each census.

Czech belongs to the West Slavic group, with Slovak, Polish and Sorbian. Its closest relative is Slovak, and speakers of the two languages understand each other with little effort, a legacy of the decades they spent in one state. How the language works is covered in our short introduction to Czech, and the sounds are covered in the guide to Czech pronunciation.

Two kinds of Czech

A learner will meet two forms of the same language. Standard Czech (spisovná čeština) is the written and formal language, used in newspapers, textbooks, court papers and news bulletins. Common Czech (obecná čeština) is the spoken everyday form, especially in Bohemia, where endings and some vowels differ from the textbook. A Prague speaker says things in a way that a grammar book would not print. The differences are part of why a good course feels unlike the street. On top of that comes regional speech: Moravia and Czech Silesia have their own dialects, and a Moravian will often sound different from a Praguer within a sentence.

Which minorities and languages are present?

Czechia is far more uniform than it was before the Second World War, when it had a large German-speaking population in the border regions. Most Germans were expelled after 1945, a subject covered in our piece on Czech Germans and the Sudetenland. The present minorities are smaller. Slovaks, Ukrainians, Vietnamese, Poles, Russians and Germans are among the largest groups. The state recognises a list of national minorities by law, including the Roma, Bulgarians and Hungarians; the exact list is kept by the government's minority council. The demographic picture is covered in our piece on the ethnic and linguistic make-up of the population.

Two points of law are worth knowing:

1. The minorities act lets a minority language be used in dealings with officials, and on bilingual place signs, in municipalities where the minority reaches a set share of residents in the census. The threshold is in the act (check the current text). In practice it covers few places, the best known being Polish-speaking municipalities in the north-east.
2. Czech Sign Language has its own act, which recognises it and gives deaf people the right to use it and to interpretation. Check the current text for the details.

Since 2022 many Ukrainian speakers have arrived, and Ukrainian is now heard in schools, shops and on public transport. It is not an official language, though some public bodies publish information in it. Background is in our piece on Czechia and Ukraine.

How far does English get you?

The honest answer is that it depends on where you stand.

In Prague's centre, in tourism and in international companies: English is the working language of much of the service sector. Menus, hotel desks, ticket offices for museums and many shops have English-speaking staff, and in international offices the working language is English. Younger Czechs usually speak it well, as it is the main foreign language taught in schools.

In public offices: The language of the administration is Czech. Staff at some offices that handle foreigners speak English, but this is a courtesy rather than a right. Forms are in Czech, official letters arrive in Czech and a data box message will be in Czech. For a decision that matters, such as a residence application or a tenancy contract, bring a translator or a Czech-speaking friend, and use a sworn translator when a document has legal weight.

Outside Prague: English is less common, though still easy to find among under-40s in the larger cities. In villages, older people may know more German or Russian than English. Russian was a compulsory school subject in the communist period, and many older Czechs learned it, though not all are keen to use it now.

Language at work and at school

Employment contracts in Czechia are normally written in Czech, and a foreign employee may ask for a parallel English version. If the two versions differ, check which one the contract says prevails. The same applies to rental contracts, where a bilingual text is common in Prague but the Czech version is the one a court would read. The general principle is simple: you may sign anything in any language, but the dispute will be settled in Czech.

State schools teach in Czech. A child who arrives without it is usually offered Czech as a second language, and schools can receive extra support, a process described in our guide to enrolling a child in a Czech school. Families who prefer English tuition usually look at the international schools, which are discussed in a separate piece on choosing an international school.

Names, signs and the written word

A visitor will notice that Czech uses the Latin alphabet with diacritics, so street signs, menus and forms are readable in a basic way even before the grammar is. The marks matter. A hook on a letter changes the sound, and a missing one on a form can create an official mismatch. Street names stay in Czech even on English-language maps, so Náměstí Míru does not become "Peace Square" in the metro announcement.

What the law asks of learners

For most visitors, the language never becomes a legal matter. For people planning to stay, it does. Permanent residence requires Czech at level A2 and citizenship requires B1 plus a civics test (as of 2026). The Ministry of the Interior sets the rules, and the exam bodies publish formats and dates: the National Pedagogical Institute (NPI) for the residence exam, Charles University's language institute for citizenship. The requirements are laid out in our guide to language requirements for residence and citizenship and the exam format in the piece on Czech language exams for foreigners.

How to start in the first week

Learning a few phrases pays back at once. Czechs notice the effort, and the shopkeeper who has just heard a clumsy dobrý den will often switch to English with a smile. Our guide to hello, thank you and goodbye in Czech covers the basics. Greeting on entering a small shop is expected, and so is the farewell on leaving.

Frequently asked questions

Do I need Czech to live in Prague?

You can manage daily life in English in central Prague, particularly in international workplaces. For official business, health care and long-term plans, some Czech helps a great deal, and a certain level is required for permanent residence and citizenship.

Is Czech similar to Russian?

Both are Slavic languages and share some roots, but Russian uses the Cyrillic alphabet and the two are not mutually understandable in the way Czech and Slovak are.

Do Czechs speak German?

Some do, especially older people in border regions and in tourism. English is now the first foreign language for most young people.

Can I use English with Czech authorities?

Sometimes informally, but official proceedings are held in Czech. You may need an interpreter or translator for important matters.

Is Slovak an official language in Czechia?

No, but Slovaks are the largest minority. Slovak is widely understood, and Slovak television and books are common.
