Czech Alphabet: Why ú and ů Sound Alike and What ě Does

Czech marks length and sound on top of the Latin a to z. A čárka (á é í ó ú ý) or a kroužek (ů) makes a vowel long. A háček changes a consonant (č ď ň ř š ť ž) or, on ě, the consonant before it. Ch is a single letter, filed after h.

What are the letters of the Czech alphabet, in order?

The Unicode CLDR lists 42 letters for Czech, from a to ž. The 15 lit ones are letters English does not have: á č ď é ě í ň ó ř š ť ú ů ý ž. Tap a capital or a small letter to copy it.

The order is CLDR's collation for Czech, applied by ICU 78.3 (CLDR 48.0).

Which Czech letters go beyond a to z?

15 letters of the Czech alphabet are not in English, and each carries a mark. Of these, á, č, é, í, ó, ř, š, ť, ú, ý and ž link to their own page with every shortcut.

How do you type the Czech letters on each device?

Each row gives the method the vendor documents for one Czech letter. The help pages are linked at the end.

Which English words keep á, č, ď, é, ě, í, ň, ó, ř, š, ť, ú, ů, ý or ž?

Wiktionary lists these English words spelled with each letter, most common first by how often they appear in English subtitles:

é
  • fiancé
  • fiancée
  • café
  • cliché
  • résumé
  • olé
  • touché
  • attaché
  • séance
  • protégé
ó
adiós

Wiktionary lists no English word with á, č, ď, ě, í, ň, ř, š, ť, ú, ů, ý and ž that English subtitles use.

Why does Czech spell one long u as both ú and ů?

Because two old sounds merged, and the Czech alphabet kept a letter for each. The ÚJČ handbook (opens in a new tab), from the Czech Academy of Sciences' Institute of the Czech Language, says ú and ů sound exactly alike. Kúra and kůra are both said [kúra]. Wiktionary gives kúra (opens in a new tab) as a course of treatment, a cure, and kůra (opens in a new tab) as bark or crust. Only the letter tells them apart.

The ring is a leftover letter. ÚJČ's history of Czech spelling (opens in a new tab) traces it. Old Czech had a long ó. From the end of the 14th century it turned into the diphthong uo, and then into a long ú.

Scribes wrote that uo as a u with a small o above it, though uo in full lasted in writing until the middle of the 16th century. So the kroužek was once an o, and ů now writes the ú that grew out of it.

The old ú changed too. By the end of the 16th century it had become ou inside a word, so lúka became louka. At the start of a word it stayed ú: údolí, never oudolí. That history gives the rule below, from the handbook's page on ú and ů (opens in a new tab).

Where the long u standsWriteÚJČ's examples
first letter of a wordúúl, úcta, Ústí
after a prefix, if the base word starts with úúneúcta, bezúhonný
start of the second part of a compoundútrojúhelník, samoúčelný
a word taken from another languageúmúza, túra, kúra
inside a native rootůdům, růže, kůra
in a prefixůdůkaz, průvodce
the suffix ‑ůvůbratrův, Benešův
a case endingůstromů, stromům
the adverbs domů and dolůůdomů, dolů
one word allowed both waysú or ůštrúdl, štrůdl

The ‑ův row shows up on the map. Havlíčkův Brod and Jindřichův Hradec, in the names and places block below, end their first word in that suffix. Bratrův is built the same way from bratr, and Ondřejův from Ondřej.

On a Czech keyboard the two letters sit apart: ú right of P and ů right of L. The Czech keyboard page draws all three Windows layouts for Czech and types every letter here.

What does ě do to the consonant before it in Czech?

The letter ě tells you how to read the consonant before it. The ÚJČ page on the letter ě (opens in a new tab) says it stands only after d, t, n, after b, p, v, f, and after m. The e itself is an ordinary e. What changes is the sound before it. The meanings below are Wiktionary's, for děsit (opens in a new tab), něha (opens in a new tab), běhat (opens in a new tab) and město (opens in a new tab).

WrittenSaidExampleMeaning
dě, tě, ně[ďe], [ťe], [ňe]děsit, said [ďesit]; něhato horrify; tenderness
bě, pě, vě, fě[bje], [pje], [vje], [fje]běhat, said [bjehat]to run
mě[mňe]město, said [mňesto]city

So the first row is a spelling trade. The handbook notes that ďe, ťe and ňe never appear in Czech writing. Where the sound is ďe, you write dě, and the háček moves from the consonant to the vowel.

The second row has exceptions. After p and f, Czech writes only ě, never je. After b and v it writes je where a prefix meets a root that starts with je: objem (opens in a new tab), volume, and vjezd (opens in a new tab), a driveway. The m row has a twin spelling, mně, which the FAQ below sorts out.

Which Czech marks make a vowel long, and what does length change?

The čárka and the kroužek. The handbook's page on Czech vowels (opens in a new tab) sets short i, e, a, o, u against long í, é, á, ó, ú. It says the difference can change what a word means, and gives the pairs below. The English meanings come from Wiktionary's entries for vila (opens in a new tab) and víla (opens in a new tab), pas (opens in a new tab) and pás (opens in a new tab), peče (opens in a new tab) and péče (opens in a new tab), lože (opens in a new tab) and lóže (opens in a new tab), and kul (opens in a new tab) and kůl (opens in a new tab).

Short vowelMeaningLong vowelMeaning
vilavillavílafairy
paspassportpásbelt, waist
pečebakespéčecare
ložebed, in literary uselóžea box for spectators
kulforgedkůlstake, post

The last row is the ů from the first section at work: the ring and the čárka are both length marks. The ý is too. It is a long y, and y is said like i, so ý sounds like í. The handbook adds that ó is mostly found in words from other languages, such as móda, and in names.

In Czech, a slip in vowel length is a real error, not a matter of style. Write vila for víla and the fairy becomes a villa. A spell checker accepts both, because both are words.

Where do ch and the háček letters go in a Czech dictionary?

In Czech alphabetical order, ch goes between h and i, and č, ř, š and ž each follow their base letter. The handbook's sorting rules (opens in a new tab) cite the Czech standard ČSN 97 6030 for this.

The standard's primary row reads a, b, c, č, d, e, f, g, h, ch, i, j, k, l, m, n, o, p, q, r, ř, s, š, t, u, v, w, x, y, z, ž. The lengthened vowels and ď, ě, ň and ť are not in that row. They sort as the plain letter, and the mark counts only between words that are otherwise the same.

ÚJČ's examples show both ranks at once. Ďábel, the devil (opens in a new tab), sits between da capo and dabing, as if it were dabel. Schody comes after shoda, because sch is s and then the letter ch. When marks are the only difference, the word with its mark nearer the end comes first: kanon, kanón, kaňon, kánon.

We ran these words through the locale-aware compare in Node.js v26.0.0, which runs ICU 78.3 on CLDR 48 data, on 2026-10-10. Czech rules matched every ÚJČ example. English rules differ where a háček letter or ch decides.

Two wordsUnder Czech rulesUnder English rules
hrad, chlébhrad firstchléb first
cukr, čajcukr firstčaj first
ruka, řekaruka firstřeka first
dabing, ďábelďábel firstďábel first

The ďábel row is the control. Ď sorts as a plain d in Czech, and English rules do the same. Search shows the same split. In the same test, a Czech-rules search that ignores accents found kůra when asked for kura. It did not find česko when asked for cesko. To a Czech collator, č is a different letter and ů is only a long u.

Two lists of Czech alphabet letters exist, and they differ only on q, w and x. The handbook's list of letters for Czech sounds (opens in a new tab) leaves them out. The sorting row above puts them back, and so does the alphabet at the top of this page, which comes from the CLDR alphabetic information chart (opens in a new tab).

Why is the Czech ř so rare, and who says r instead?

Because the sound itself is rare. ÚJČ's history of Czech spelling (opens in a new tab) calls ř very unusual among the languages of the world. It arose in the 13th century from a softened r, and the oldest written evidence for it dates from 1237. That r stood before e, ě or i, or before a lost soft vowel, or in the group rj. The handbook traces řeka, řepa, tři and moře back to forms with a plain soft r.

There are two ř sounds, and one letter of the Czech alphabet for both. Ř is voiced in řeka and dveře. It loses its voice next to a voiceless consonant, as in křik, and at the end of a word, as in keř. No pair of Czech words differs only by the two, so the spelling never needed a second letter.

Not every Czech speaker says it. In the kopaničáři dialects of south-east Moravia, by the Slovak border, people say orech for ořech and repa for řepa.

The handbook puts this down to Slovak settlers or to the neighbouring West Slovak dialects. Early scribes had no letter for ř either. They wrote r, rs or rz, until a mark over the r took over; how that mark became the háček is told on the caron page.

How to type Czech letters, step by step

Step 1: Mac: ú with Option+E, ů from the Character Viewer

Press Option+E, then U, to type ú. The ring has no such key, so for ů press Fn/Globe+E and search latin small letter u with ring above. The same search with e with caron finds ě.

Step 2: Microsoft Word: ř, ě and ů by their code

Type 0159 and press Alt+X to turn it into ř. The code 011b gives ě and 016f gives ů. Word replaces the code with the letter as you type.

Step 3: Windows: Win+. for the háček letters

Press Win+. to open the emoji panel and choose Symbols. Pick č, ď, ě, ň, ř or ť among the Latin symbols, and it is typed where the cursor stands.

Step 4: Google Docs: search Special characters

Choose Insert, then Symbols, then Special characters, and search a name such as latin small letter r with caron. Click ř to place it in the document.

Which other letters does the CLDR list for Czech?

Frequently asked questions about Czech letters

Can a Czech word start with ů?

Not a native one. The ÚJČ handbook puts ú at the start of a word, as in úl, a beehive, and úcta, respect. It puts ů inside the word: in a root such as dům, in a prefix such as průvodce, a guide, and in endings. A word that starts with the long u sound starts with ú.

Is ch one letter or two in Czech?

One. The ÚJČ handbook says ch, made of c and h, counts as a single letter in Czech, unlike in other languages, because it writes a single sound. Dictionaries file it between h and i, so chléb comes after hrad. At the start of a capitalised word it is written Ch, as the grid at the top shows.

Why does the ÚJČ list of Czech letters leave out q, w and x?

Because that list holds the letters for Czech sounds. The handbook adds that q, w and x occur in words of foreign origin, and that names and quotations bring in more, such as ä, ö, ü, ç, ñ and ł. Its sorting rules do give q, w and x a place, between p and r, v and y. CLDR lists them too.

Do you write mě or mně in Czech?

Both are said [mňe]; the word you start from decides. The ÚJČ handbook writes mně when the base word has mn or men: jemný gives jemně, finely. Without mn in the base, write mě: zima gives v zimě, and rozum gives rozumět. Root words such as město, a city, also take mě.

Are i and y said differently in Czech?

No. The ÚJČ handbook says bili, bily, byli and byly are all said [bili], so speech alone cannot tell them apart. The two letters keep a sound difference that old Czech lost. The long í is a little closer than short i, which some listeners mistake for a difference between i and y.
