Irregular Present Tense Patterns in Polish

In Brief

Several everyday Polish verbs change their stem (the core part that carries the meaning) when they enter the present tense: spać → śpię, stać → stoję, brać → biorę, and pisać → piszę. Learn the infinitive together with the “I” and “you” forms—such as brać: biorę, bierzesz—and the rest of the pattern becomes much easier to predict.

Overview

Polish verbs change their endings according to person (who performs the action) and number (one person or more than one). English says “I write,” “you write,” and “we write,” with little change to the verb. Polish uses piszę, piszesz, and piszemy. Because the ending usually identifies the subject, Polish can also leave out pronouns such as ja (“I”) and my (“we”).

This A1 topic deals with four very common verbs whose present forms cannot be made by simply cutting -ć from the infinitive (the dictionary form). Their stems show vowel or consonant alternations: a may disappear or become another vowel sequence, while consonants may become “softer” or change spelling. These alternations reflect regular features of Polish word formation, but a beginner does not need to derive every sound change.

The most useful approach is to treat each verb as a small pattern rather than as six unrelated words. The four verbs here are all imperfective: they present sleeping, standing, taking, or writing as an ongoing, repeated, or general activity. Their present tense can therefore correspond to either the English simple present or the present continuous: Piszę list can mean “I write a letter” or “I’m writing a letter,” depending on context.

How It Works

Start with two key forms

For a new Polish verb, record these three items:

• the infinitive: brać (“to take”);
• the first-person singular: (ja) biorę (“I take / I’m taking”);
• the second-person singular: (ty) bierzesz (“you take / you’re taking”).

The two present forms reveal the stem alternation and the set of endings. This is more reliable than guessing from the infinitive. Parentheses around a pronoun mean that it is optional in an ordinary sentence.

The personal endings

The four verbs use closely related endings, but their stems behave differently. Notice especially -ę for “I,” -sz for informal singular “you,” and -ą for “they.”

Person	spać	stać	brać	pisać
(ja) — I	śpię	stoję	biorę	piszę
(ty) — you, singular informal	śpisz	stoisz	bierzesz	piszesz
(on/ona/ono) — he/she/it	śpi	stoi	bierze	pisze
(my) — we	śpimy	stoimy	bierzemy	piszemy
(wy) — you, plural	śpicie	stoicie	bierzecie	piszecie
(oni/one) — they	śpią	stoją	biorą	piszą

The polite singular forms pan (“sir/Mr.”), pani (“ma’am/Ms.”), and państwo (a polite mixed group or couple) use third-person forms: Czy pani bierze kartę? (“Are you taking the card?”), Czy państwo piszą? (“Are you writing?”).

Pattern 1: spać → śpię, śpisz

In spać (“to sleep”), the infinitive stem spa- changes to śpi- / śp-. The spelling distinction matters: ś is a soft sound, not plain s. Before i, Polish writes si to represent that softness, as in śpisz and śpi. Before the ending -ę or -ą, it writes ś: śpię, śpią.

For practical purposes, learn the present base as śpi-: śpię, śpisz, śpi, śpimy, śpicie, śpią. Do not preserve the a from the infinitive.

Pattern 2: stać → stoję, stoisz

Stać (“to stand”) has the present stem stoj- / stoi-: stoję, stoisz, stoi, stoimy, stoicie, stoją. The sequence oj appears before -ę and -ą, while the other forms contain oi: stoję but stoisz.

This verb refers to being upright or stationary: Samochód stoi przed domem means “The car is parked/is standing in front of the house.” Do not confuse it with zostać (“to remain; to become,” depending on context), which is a different verb.

Pattern 3: brać → biorę, bierzesz

Brać (“to take”) has two visibly different present stems:

• bior- in biorę and biorą;
• bierz- in bierzesz, bierze, bierzemy, and bierzecie.

The pair biorę–bierzesz is worth memorizing as one unit. If you know only biorę, you may wrongly produce forms such as biorzesz. The alternation between o and e, together with r and rz, belongs to the verb’s pattern.

Pattern 4: pisać → piszę, piszesz

In pisać (“to write”), s alternates with sz throughout the present tense: piszę, piszesz, pisze, piszemy, piszecie, piszą. English speakers should pay attention to the spelling and sound of sz, roughly like “sh” in English.

This pattern is not unique to one word. Related prefixed verbs preserve the alternation, for example napisać → napiszę, napiszesz. However, aspect changes the time reference of such forms; this is explained under “Beyond the Basics.”

Pronouns are usually optional

The ending tells the listener who acts, so neutral Polish normally says Śpię rather than Ja śpię. Include the pronoun for contrast, correction, or emphasis:

• Ja piszę, a ty czytasz. — “I’m writing, while you’re reading.”
• Nie on. Ona bierze klucze. — “Not him. She is taking the keys.”

English requires a stated subject in these sentences. Carrying that English habit into Polish is not grammatically wrong, but repeating ja, ty, or my in every sentence can sound unnecessarily emphatic.

Examples in Context

Polish	English	Note
Śpię.	I sleep. / I’m sleeping.	The pronoun ja is understood.
Dziecko już śpi.	The child is already asleep.	Third-person singular of spać.
W weekend śpimy dłużej.	We sleep longer at the weekend.	A repeated habit.
Stoję tutaj.	I’m standing here.	Present action.
Autobus stoi przed szkołą.	The bus is standing outside the school.	Polish can use stać for a stationary vehicle.
Dlaczego stoicie na korytarzu?	Why are you all standing in the corridor?	Plural informal “you.”
Biorę to.	I’m taking it.	First-person singular of brać.
Czy bierzesz cukier do kawy?	Do you take sugar in your coffee?	A habitual preference.
Dzieci biorą kanapki do szkoły.	The children take sandwiches to school.	Third-person plural.
Piszę list.	I’m writing a letter.	Ongoing action.
Ona często pisze do babci.	She often writes to her grandmother.	Repeated action; do takes the genitive form babci.
Piszemy wiadomość do nauczyciela.	We’re writing a message to the teacher.	First-person plural.
Ja biorę mapę, a ty piszesz adres.	I’ll take the map, and you write down the address.	Pronouns mark a contrast between roles.
Państwo stoją w dobrej kolejce.	You are in the right queue.	Polite address to more than one person.

Common Mistakes

Building the present form directly from the infinitive

• Wrong: Ja spacę osiem godzin.
• Right: Śpię osiem godzin.
• Why: Spać does not keep spa- in the present. Its present forms use śpi- / śp-.

Using one stem throughout brać

• Wrong: Biorzesz parasol?
• Right: Bierzesz parasol?
• Why: Use bior- only in biorę and biorą. The other four forms use bierz-.

Missing the consonant change in pisać

• Wrong: Pisę e-mail.
• Right: Piszę e-mail.
• Why: Present-tense pisać has sz in every person: piszę, piszesz, and so on.

Keeping a in stać

• Wrong: Stam przed domem.
• Right: Stoję przed domem.
• Why: The present stem is stoj- / stoi-, not sta-.

Translating English present forms too literally

• Wrong idea: Polish needs a separate construction equivalent to “I am writing.”
• Right: Piszę can mean both “I write” and “I am writing.”
• Why: Context and time expressions distinguish a current action from a habit: Teraz piszę (“I’m writing now”) versus Często piszę (“I often write”).

Stating every subject pronoun

• Less natural in a neutral context: Ja piszę list. Ja biorę kopertę. Ja stoję przy oknie.
• More natural: Piszę list. Biorę kopertę. Stoję przy oknie.
• Why: The endings already identify “I.” Use ja when you genuinely mean “I, as opposed to someone else.”

Usage Notes

All four verbs are frequent in ordinary speech. Their bare present forms are neutral in register: they work in conversation and writing. What changes with politeness is primarily the form of address. Use second-person singular with ty among friends, relatives, children, and people who have agreed to use it; use third-person forms with pan or pani in many polite interactions: Czy pani pisze po polsku? (“Do you write in Polish?”).

English “take” covers many meanings, and brać covers many—but not all—of them. It is natural in brać lek (“take medicine”), brać prysznic (“take a shower”), and brać udział (“take part”). However, fixed expressions do not always match English word for word, so learn the noun and verb together.

The Polish present tense itself does not make the English distinction between “writes” and “is writing.” Adverbs often clarify the intended reading: zwykle (“usually”), często (“often”), codziennie (“every day”), teraz (“now”), and w tej chwili (“at this moment”).

Beyond the Basics / Advanced Use

You do not need to master aspect yet, but you will soon notice that Polish verbs often come in aspectual pairs. Aspect shows whether an action is viewed as a process or repeated activity (imperfective) or as a single completed whole (perfective). Pisać is imperfective, while napisać commonly presents writing as completed; brać is imperfective, while wziąć is a common perfective partner.

A crucial later rule is that perfective verbs do not have a true present-tense meaning. Their present-looking forms normally refer to the future:

Polish	English	Note
Piszę list.	I’m writing a letter.	Imperfective: present process.
Napiszę list.	I’ll write the letter.	Perfective: future completion.
Biorę parasol.	I’m taking an umbrella.	Imperfective present.
Wezmę parasol.	I’ll take an umbrella.	Perfective future; a different stem.

Prefixes can preserve a familiar consonant pattern without preserving present time. For example, podpisać (“to sign”) gives podpiszę, but as a perfective verb podpiszę dokument usually means “I will sign the document.” Always learn a prefixed verb together with its aspect and meaning.

At a more advanced level, you will also meet verbs that share some of these alternations: przepisać → przepiszę (“copy/rewrite”), opisać → opiszę (“describe”), and imperfective derivatives such as podpisywać → podpisuję (“to be signing/to sign repeatedly”). Similar spelling does not guarantee identical conjugation, so use patterns as memory aids rather than universal formulas.

Practice Tips

1. Learn three forms aloud. Make cards such as brać — biorę — bierzesz and stać — stoję — stoisz. The “I” and “you” forms expose the important stem changes.
2. Build six short sentences from one setting. For example: Ja piszę. Ty piszesz. Ona pisze. My piszemy. Wy piszecie. Oni piszą. Then repeat without pronouns to train yourself to hear the endings.
3. Contrast “now” with “usually.” Pair Teraz piszę wiadomość with Zwykle piszę rano. This practices the Polish present tense without forcing an English simple-versus-continuous distinction onto it.
