Why learn Czech words by frequency
A handful of words do most of the work in any language, and Czech is no exception. Little words like a (and), v (in), na (on) and být (to be) appear in almost every sentence. If you learn vocabulary in frequency order, every word you add is one you will actually meet.
The list shows dictionary forms
Czech nouns, adjectives and pronouns change their endings for case, and verbs change for person and tense. The list gives each word in its dictionary form: the nominative for nouns, the infinitive for verbs. So být appears once, but you will meet it as jsem, je, jsou, byl and bude. Ten (that) turns up as ta, to, toho, tom and more.
Words that surprise learners
- se is the reflexive particle, and it sits beside many verbs that are not reflexive in English: učit se means "to learn", jmenovat se "to be called".
- v / ve and s / se: these prepositions gain an -e before a cluster of consonants that would be hard to say, as in ve škole (at school) and se sestrou (with my sister). That se means "with" and has nothing to do with the reflexive se.
- ten, ta, to: Czech has no articles, so ten often does the job English gives to "the".
How to make them stick
Knowing a word means recognising it in a sentence and recalling it when you need it. Reading a list once does neither. Spaced repetition does: you review each word just before you would forget it. That is how the Czech Learner drill works. Add the words to your drill and it schedules the reviews for you.

What is the most common word in Czech?
Counted by dictionary form, být ("to be") is the most common word in Czech, just ahead of a ("and"). It comes first because every form of it, such as je, jsem, byl and bude, counts towards the same word.
How many Czech words do I need to know?
There is no single number, but a few hundred of the most frequent words cover a large share of everyday Czech. That makes the first 500 a good target for a beginner. After them, most new words you meet are the less common ones that carry the specific meaning of a sentence.
Where does this list come from?
It is ranked by how often each dictionary form appears in a large collection of real Czech text. The English meanings are written for learners, so they give the sense you will need most often rather than every dictionary meaning.
