Irregular Present Tense Patterns in Czech

In Brief

Some common Czech verbs change their stem when they move from the infinitive to the present tense: spát → spím, stát → stojím, brát → beru, and psát → píšu. Learn the present stem together with the infinitive rather than trying to attach endings directly to the form in -át. Once you know the changed stem, most of the remaining forms follow a clear pattern.

Overview

The infinitive is the dictionary form of a verb, such as spát “to sleep” or psát “to write.” With many Czech verbs, you can recognize the present-tense form fairly easily from that dictionary form. The four frequent verbs in this article are less transparent: their vowels, consonants, or both change in the present tense.

This is an A1 topic because these verbs appear constantly in ordinary conversation. You need them to say where you are standing, what you are writing, what you take, and whether you are sleeping. The useful beginner strategy is not to search for one rule that predicts every change. Instead, memorize a compact pair: infinitive + first-person singular, for example psát — píšu. That pair reveals the present stem and the ending pattern.

English speakers must also adjust to a broader difference. English uses nearly the same present form for most persons: “I sleep,” “you sleep,” “we sleep.” Czech changes the verb ending for each grammatical person (the speaker, the listener, or someone else) and often leaves out the subject pronoun because the ending already identifies the subject.

How It Works

Start with the present stem, not the infinitive

Removing -t from these infinitives does not produce the form you need. Compare the dictionary form with the first-person present form:

Infinitive	Meaning	Present stem seen in forms	First person singular	Main change
spát	to sleep	sp- with long í	spím	á → í
stát	to stand	stoj-	stojím	á → oj
brát	to take	ber-	beru	the stem becomes ber-
psát	to write	píš-	píšu	á → í and s → š

These alternations are established parts of the verbs. They are not freely productive rules: knowing that psát becomes píšu does not mean that every infinitive in -sát behaves in exactly the same way. A dictionary normally gives enough information to identify an unfamiliar verb’s conjugation.

Pattern 1: spát and stát

Both spát and stát use the endings -ím, -íš, -í, -íme, -íte, -í. Their stems are different, but the set of endings is the same.

Person	spát — to sleep	stát — to stand
já — I	spím	stojím
ty — you, informal singular	spíš	stojíš
on / ona / ono — he / she / it	spí	stojí
my — we	spíme	stojíme
vy — you, plural or formal	spíte	stojíte
oni / ony / ona — they	spí	stojí

Notice that the third-person singular and plural forms are identical: on spí and oni spí. The subject, the surrounding words, or the wider context shows whether the meaning is singular or plural.

The pronouns are included in the table to make the persons clear. In a real sentence, Czech usually omits them when there is no contrast: Spím already means “I sleep” or “I’m sleeping.”

Pattern 2: brát

The present stem of brát is ber-. It combines with the endings -u, -eš, -e, -eme, -ete, -ou.

Person	Form	English
já	beru	I take / I’m taking
ty	bereš	you take / you’re taking
on / ona / ono	bere	he / she / it takes
my	bereme	we take / we’re taking
vy	berete	you take / you’re taking
oni / ony / ona	berou	they take / they’re taking

The vowel e stays throughout the stem. Do not mix this verb with the -ím pattern: the first-person form is beru, not berím.

Pattern 3: psát

The stem of psát changes to píš-. Its everyday forms use the same basic ending set as brát, but š remains part of the stem.

Person	Form	English
já	píšu	I write / I’m writing
ty	píšeš	you write / you’re writing
on / ona / ono	píše	he / she / it writes
my	píšeme	we write / we’re writing
vy	píšete	you write / you’re writing
oni / ony / ona	píšou	they write / they’re writing

You will also encounter píši for “I write” and píší for “they write.” These are standard variants; píši has a more formal or literary feel than everyday píšu, while píší is especially common in more formal writing. A beginner can confidently use píšu and píšou in normal conversation.

Negatives and questions

Negation is straightforward: add ne- directly to the conjugated verb.

Positive	Negative	Meaning
Spím.	Nespím.	I sleep / I do not sleep.
Stojí tady.	Nestojí tady.	He/she is standing here / is not standing here.
Bereme to.	Nebereme to.	We are taking it / are not taking it.
Píše.	Nepíše.	He/she writes / does not write.

Yes-or-no questions do not require an English-style auxiliary such as “do.” Intonation and context can turn the same order into a question: Spíš? means “Are you sleeping?” or “Do you sleep?” Question words simply come before the verb: Kde stojíš? “Where are you standing?”

Examples in Context

Czech	English	Note
Spím.	I sleep. / I’m sleeping.	The ending -ím identifies “I.”
Spím osm hodin.	I sleep for eight hours.	A general habit.
Dítě už spí.	The child is already asleep.	Third-person singular.
Spíte dobře?	Do you sleep well?	Vy can be plural or polite singular.
Stojím tady.	I’m standing here.	Present action.
Kde stojíš?	Where are you standing?	Informal singular “you.”
Auto stojí před domem.	The car is parked in front of the house.	Literally, the car “stands.”
Kolik to stojí?	How much does it cost?	stát also means “to cost.”
Beru to.	I’m taking it.	Common immediate use of brát.
Beru léky každý den.	I take medicine every day.	Repeated action.
Co bereš?	What are you taking?	The pronoun ty is unnecessary.
Dnes si bereme taxi.	We’re taking a taxi today.	si is common with choosing or getting something for oneself.
Píšu dopis.	I’m writing a letter.	The stem is píš-.
Píšeme e-mail učiteli.	We’re writing an email to the teacher.	First-person plural.
Komu píšete?	Who are you writing to?	Polite singular or plural “you.”

Common Mistakes

Attaching a regular-looking ending to the infinitive stem

• Wrong: Já psám dopis.
• Right: Píšu dopis.
• Why: The present stem of psát is píš-, not psá-. Learn psát — píšu as a pair.

Using the right stem with the wrong ending

• Wrong: Já berím léky.
• Right: Beru léky.
• Why: Brát uses the beru, bereš, bere pattern, not the -ím, -íš, -í pattern.

Forgetting the person shown by the ending

• Wrong: Já spíš osm hodin.
• Right: Já spím osm hodin.
• Why: -íš belongs to informal singular “you”; -ím belongs to “I.” The pronoun and verb must refer to the same person.

Adding an equivalent of English “be”

• Wrong: Jsem píšu dopis.
• Right: Píšu dopis.
• Why: Czech does not build a present progressive with jsem “I am.” A single present-tense verb can express both English “I write” and “I am writing.”

Expecting a separate plural form after an -í stem

• Wrong: Oni spíjí.
• Right: Oni spí.
• Why: In this pattern, third-person singular and plural are identical: on spí and oni spí.

Dropping Czech diacritics

• Wrong: Pisu dopis.
• Right: Píšu dopis.
• Why: í marks a long vowel, and š is a different consonant from s. Diacritics are part of Czech spelling, not optional decorations.

Usage Notes

One Czech present tense, two common English translations

Czech does not make the same grammatical distinction as English between “I write” and “I am writing.” Píšu can mean either. Time expressions and context usually make the intended meaning clear:

• Píšu každý den. — “I write every day.”
• Teď píšu. — “I’m writing now.”

The same applies to spím, stojím, and beru. Do not automatically add an extra Czech verb because the English translation contains “am,” “is,” or “are.”

Pronouns are often omitted

Because spím, spíš, and spíme already show different persons, neutral Czech usually does not need já, ty, or my. Use a pronoun when contrasting people or correcting an assumption: Já píšu, ty čteš means “I’m writing; you’re reading.”

Vy has two uses

The form in the vy row addresses more than one person or one person politely. Thus Píšete? can mean “Are you all writing?” or the polite “Are you writing?” Context determines which reading is intended.

Stát covers more than physical standing

Besides describing a person or object in a stationary position, stát can mean “to cost”: Kolik stojí káva? “How much does the coffee cost?” A vehicle that is not moving may also stojí, even where natural English would say it “is parked” or “is stopped.”

Beyond the Basics / Advanced Use

You do not need to master these points at A1, but they explain forms that you will meet later.

Aspect affects the time meaning

Czech verbs have aspect (a way of presenting an action as ongoing/repeated or as a complete whole). The four verbs taught here are normally imperfective, so their present forms can describe what is happening now or what happens regularly. Related perfective verbs often use present-looking endings with future meaning:

Imperfective present	Meaning	Related perfective form	Usual meaning
Píšu dopis.	I’m writing a letter.	Napíšu dopis.	I’ll write / finish writing a letter.
Beru si knihu.	I’m taking a book.	Vezmu si knihu.	I’ll take a book.

The perfective partner is not always formed by simply adding a prefix; brát and vzít have very different stems. Learn aspectual partners as vocabulary pairs when they are introduced.

One infinitive can hide different conjugations

Stát meaning “to stand” or “to cost” has the present form stojím or stojí. However, stát se meaning “to happen” or “to become” uses forms such as stane se and normally has future meaning because it is perfective: Co se stane? “What will happen?” The identical infinitive spelling does not guarantee an identical present stem or meaning.

Habitual derived forms

Later you may see derived verbs such as spávat or psávat. They emphasize that something happens habitually or from time to time: Spávám málo means roughly “I tend to sleep little.” These are separate verb forms and should not be confused with the basic present spím or píšu.

Practice Tips

1. Memorize two forms per verb first. Make cards with spát — spím, stát — stojím, brát — beru, and psát — píšu. Say each pair aloud before learning the full table.
2. Build person ladders. Cover the table and recite beru, bereš, bere, bereme, berete, berou. Then use each form in a short sentence instead of drilling endings alone.
3. Contrast “now” and “usually.” Write pairs such as Teď píšu e-mail and Píšu každý den. This trains you to let context choose between the English simple and progressive translations.
