Czech vs Polish: 300 Words That Are Nearly Identical

Czech vs Polish: 300 Words That Are Nearly Identical: the list

Tips

• Czech adjectives in -ý regularly match Polish adjectives in -y: dobrý/dobry (good), nový/nowy (new), starý/stary (old), malý/mały (small), prostý/prosty (simple). Once this clicks, you can often guess the adjective in either direction.
• Many Czech infinitives in -t correspond to Polish infinitives in -ć: myslet/myśleć (to think), stát/stać (to stand), znát/znać (to know), zabít/zabić (to kill). Look for this swap whenever a verb feels almost-but-not-quite familiar.
• Learn the recurring spelling correspondences instead of memorising each word separately: Czech č matches Polish cz (čas/czas, time), Czech ř matches Polish rz (dobře/dobrze, well), Czech v matches Polish w (pravda/prawda, truth), and Czech kd matches Polish gd (nikdy/nigdy, never).
• Some words need no conversion at all: jak/jak (how), tu/tu (here), tam/tam (there), noc/noc (night) and syn/syn (son) are identical in both languages — a good confidence-building place to start.
• Don't let a near-perfect match tempt you to skip the grammar: sám/sam (alone) looks interchangeable, but Czech and Polish decline adjectives and pronouns differently, so the ending you need can change with case, gender and number even when the base word matches.
• Czech has no nasal vowels, so a Polish ę often shows up as a plain vowel on the Czech side — trochę/trochu (a little) is a clear example. Don't assume the Polish nasal always maps onto the same Czech letter.

Frequently asked questions

Is it true that Czech and Polish share a lot of vocabulary?

Yes — as closely related Slavic languages they share many words with the same or very similar form and meaning. This list collects concrete side-by-side examples rather than vague generalities.

Can I rely on Czech-Polish similarity instead of learning grammar?

No. Matching vocabulary gets you recognition and quick guesses, but endings still change with case, gender and number in both languages, so grammar matters even when the base word is nearly identical.

How does spaced repetition help with near-identical word pairs like these?

Because the words look so similar, it's easy to feel you already know them and then blank on the exact spelling later. Spaced repetition brings each word back just before you'd forget it, so the small letter differences stick.
