Long vowel letters
In Czech, a mark over a vowel (like á or ů) means you hold the sound longer, not that you stress it. Vowel length is crucial because it can change a word's meaning entirely.
How It Works
Unlike English 'long vowels' which often glide (like the 'o' in 'go'), Czech long vowels are steady monophthongs. You simply hold the sound longer without changing its quality.
Why it matters:
Vowel length is phonemic, meaning it distinguishes completely different words. For example, pas means 'passport', but pás means 'belt'. If you ignore the marks, you might say the wrong word!
The letters:
- á, é, í, ó, ú, ý use a čárka (acute accent). Note that í (měkké i, soft i) and ý (tvrdé y, hard y) sound exactly the same; their spelling depends on grammar rules.
- ů uses a kroužek (ring). It is a historical fossil of an old diphthong, which is why it never starts a word.
- ó is rare and mostly found in loanwords (móda) or interjections (haló).
Remember to keep your vowels clear even when they are unstressed. Do not reduce them to an English 'uh' (schwa) sound. To practice, remember that first-syllable word stress is completely separate from vowel length.

- V únoru jsme koupili nový dům.
In February we bought a new house.
Word by Word: In February [we] auxiliary bought new house.
Notice 'ú' at the beginning of 'únoru' and 'ů' in the middle of 'dům'. Both make the exact same long 'oo' sound.
- Ten pán má pas, ne pás.
That gentleman has a passport, not a belt.
Word by Word: That gentleman has passport, not belt.
Vowel length changes the meaning: 'pas' (short a) is passport, while 'pás' (long á) is belt.
- Můj táta pije červené víno.
My dad drinks red wine.
Word by Word: My dad drinks red wine.
This sentence contains several long vowels (ů, á, é, í). Remember to stress the first syllable of each word, even if the long vowel appears later.
- To je dobrý nápad.
That is a good idea.
Word by Word: That is good idea.
The 'ý' and 'á' are held longer, but the spoken stress in 'nápad' remains on the first syllable 'ná', and in 'dobrý' on 'do'.
Common Mistakes
Ignoring length marks and confusing words like 'byt' (flat) and 'být' (to be).
To je můj být.To je můj byt.Leaving out or adding a length mark can create a completely different word. 'Byt' (short y) means flat/apartment, while 'být' (long ý) is the verb 'to be'.
Using 'ú' in the middle of a native Czech word instead of 'ů'.
Máme nový dúm.Máme nový dům.The letters 'ú' and 'ů' sound exactly the same. However, 'ú' is used at the beginning of words, and 'ů' is used in the middle or at the end of native words.
