Czech for Ukrainian and Russian Speakers — False Friends & Common Mistakes
4 min read
For Ukrainian and Russian speakers, Czech feels deceptively easy — and that's exactly the trap. Hundreds of words sound familiar but mean something completely different: čerstvý means fresh (not stale), pozor is not a disgrace, and úžasný is a compliment. This guide covers Czech↔Ukrainian/Russian look-alike words ("false friends"), so it's most useful if your first language is Ukrainian or Russian — the Ukrainian and Russian versions of this article are the most detailed. If you're reading in English, the table below still shows exactly which words trip up the largest group of exam candidates.
The best-known false friends
The comparison column keeps the Ukrainian (укр.) and Russian (рус.) words in Cyrillic, with an English gloss.
| Czech word | Actually means | Careful — the similar Ukrainian/Russian word means |
|---|---|---|
| čerstvý | fresh (čerstvý chléb — fresh bread) | укр. черствий / рус. чёрствый = stale, hard — the exact opposite! (Czech for stale: tvrdý, okoralý) |
| pozor | attention (Pozor, vlak! — Watch out, a train!) | укр./рус. позор = disgrace, shame (Czech: ostuda, hanba) |
| úžasný | amazing, wonderful | рус. ужасный / укр. жахливий = terrible — the opposite! |
| ovoce | fruit (apples, pears) | рус. овощи = vegetables (Czech: zelenina) |
| zapomenout | to forget | укр. запам'ятати / рус. запомнить = to memorize — the opposite! (Czech: zapamatovat si) |
| stůl | table | рус. стул = chair (Czech: židle) |
| rodina | family | укр. родина = family too, BUT укр. батьківщина / рус. родина = homeland (Czech: vlast) |
| vůně | pleasant smell, scent | укр./рус. вонь = stench (Czech: zápach, smrad) |
| zákaz | prohibition (zákaz kouření — no smoking) | рус. заказ / укр. замовлення = an order (Czech: objednávka) |
| vedro | heat, hot weather | рус. ведро / укр. відро = a bucket (Czech: kbelík) |
| chudý | poor (has no money) | рус. худой = thin, skinny (Czech: hubený, štíhlý) |
| úroda | harvest (dobrá úroda jablek) | рус. урод / укр. виродок = an ugly person — don't be alarmed, the Czech is praising the harvest |
| trup | torso (body without head and limbs) | рус./укр. труп = a corpse (Czech: mrtvola) |
| mír | peace | рус. мир = also "the world" (Czech: svět) |
| palec | thumb (only the big finger) | рус. палец / укр. палець = any finger (Czech: prst) |
| sklep | cellar (room under the house) | рус. склеп = a crypt, tomb (Czech: hrobka) |
| žádný | no, none | not "greedy" (рус. жадный) — greedy in Czech is lakomý, chamtivý |
| pitomec | an idiot (offensive!) | sounds almost like рус. питомец = a pet (Czech: domácí mazlíček) |
On the exam you'll meet these words in the listening and reading sections — and in writing and speaking it's easy to use them wrong ("To je pozor!" instead of "To je ostuda!").
The most common mistakes of Ukrainian and Russian speakers
- Dropping "jsem/jsi" in the past tense. Neither Ukrainian nor Russian uses an auxiliary verb here; Czech requires it: correct is Včera jsem pracoval, not "Včera pracoval". On the exam this is one of the most visible mistakes.
- Short vs. long vowels. Vowel length (á, é, í…) changes meaning: byt (apartment) × být (to be), dráha × drahá. Neither Ukrainian nor Russian has phonemic length — train it by listening and reading aloud.
- Stress always on the first syllable. Czech has no mobile stress: KAvárna, not kaVÁRna.
- Czech "h" vs. "ch". Ukrainian speakers have an advantage: Czech h = Ukrainian г (hora = гора). Russian speakers must watch out not to pronounce h as a hard [g]: Praha, not "Praga".
- The vocative case (5. pád) when addressing someone. Ukrainian has it too (Томе!), Russian doesn't. In Czech: Ahoj Tomáši! Dobrý den, pane Nováku! — on the exam it matters mainly in the email and dialogue tasks.
- The reflexive "se/si" goes in second position in the sentence. Jmenuji se Olena. Včera jsem se učila. — not at the end of the sentence following the Russian pattern.
- Prepositions don't match: in Czech it's do práce, do školy (not "na práci"), na návštěvu, v Praze, na Ukrajině.
What not to worry about
The shared Slavic base is a huge advantage: cases work similarly, verbal aspect (perfective/imperfective) is familiar from the mother tongue, and thousands of words mean the same thing (voda, ruka, den, dobrý). False friends are a small, well-described set — just learn them as a list of exceptions.
Where to practice
- Practice tests in the exam format — false friends appear mostly in the reading and listening sections.
- Writing practice with AI grading — the AI will flag a mistake like a dropped jsem or a misused word and explain it.
