The Future of być: będę

The single most useful future form in Polish is będę, the future of być ("to be"). You need it for two jobs at once: to say something will be the case ("I'll be home," "it'll be cold"), and to build the imperfective compound future ("I'll be reading"). Because być has no perfective partner, będę is its only future — there is no second option to choose from. This page covers the full set, both of its jobs, and the genitive twist in the negative existential.

The forms

PersonFormMeaning
jabędęI will be
tybędzieszyou will be
on / ona / onobędziehe / she / it will be
mybędziemywe will be
wybędziecieyou (pl.) will be
oni / onebędąthey will be

Two orthographic points worth nailing now. First, będę (first person, ) and będą (third-person plural, ) differ only in the nasal vowel — and that one letter is the difference between "I will" and "they will." Second, the middle forms are spelled będzie- with the soft sound: będziesz, będzie, będziemy, będziecie. Every form keeps the ę in the first syllable.

Job 1: będę as the future copula

In its first job, będę is simply the future of "to be" — it links the subject to a location, an adjective, a noun (predicate), or an existence. This is będę + something that is not a verb.

With a location or state:

Będę w domu po szóstej.

I'll be home after six.

Jutro będzie zimno i wietrznie.

Tomorrow it'll be cold and windy.

Spokojnie, wszystko będzie dobrze.

Don't worry, everything will be fine.

With a predicate noun — and here remember that być puts its predicate noun in the instrumental case, in the future just as in the present:

Ona będzie świetną lekarką.

She'll be a great doctor. (lekarką = instrumental)

Będziemy dobrymi sąsiadami.

We'll be good neighbours. (instrumental plural)

💡
będę keeps all of być's grammar in the future. Predicate nouns still go in the instrumental (będę nauczycielem "I'll be a teacher"), and predicate adjectives agree in gender (będę szczęśliwy / szczęśliwa). The future does not change how być governs its complement — only when.

Będę szczęśliwa, jeśli zdążysz.

I'll be happy if you make it in time. (woman speaking — adjective agrees)

Job 2: będę as the future auxiliary

In its second job, będę is not "to be" at all — it is the auxiliary that builds the imperfective compound future. Here it combines with a main verb (the infinitive or the gendered participle) and carries no meaning of its own beyond "future":

Wieczorem będę czytać.

In the evening I'll be reading. (będę = auxiliary, not 'I'll be')

Od jutra będziemy się uczyć codziennie.

From tomorrow we'll be studying every day.

Będziesz pracował w nowym biurze?

Will you be working in the new office? (man addressed)

So the same word będę can mean "I will be" (copula) or just "I will [verb]" (auxiliary), and you tell them apart by what follows:

  • będę + adjective / noun / location → copula: będę gotowy ("I'll be ready")
  • będę + infinitive / -ł participle → tense auxiliary: będę czekał ("I'll be waiting")

Będę gotowy za pięć minut.

I'll be ready in five minutes. (copula + adjective)

Będę czekał na ciebie przy wyjściu.

I'll be waiting for you by the exit. (auxiliary + participle, man speaking)

💡
Recognising this split is the key skill: będę followed by a verb form is a tense marker; będę followed by an adjective, noun, or place is the verb "to be." Same word, two grammatical roles — and only the second one builds a compound tense.

być has no perfective — so będę is the whole future

Unlike most Polish verbs, być comes with no perfective partner. There is no "perfective to be," so there is no perfective simple future for it. będę is therefore the only way to put "to be" in the future — you never face the imperfective-vs-perfective choice here. (This also means być itself is never the verb you put after będę; you don't say będę być.)

The future existential — and its genitive negative

Polish expresses "there will be" with będzie / będą:

Będzie czas na kawę po spotkaniu?

Will there be time for coffee after the meeting?

Na imprezie będą wszyscy znajomi.

All our friends will be at the party.

The twist comes in the negative. Just like the present nie ma ("there isn't," + genitive) and the past nie było (+ genitive), the future existential negative is nie będzie + genitive. The thing that is absent goes into the genitive case, and the verb stays frozen as the singular nie będzie regardless of number:

Nie będzie czasu na kawę.

There won't be time for coffee. (czasu = genitive)

Niestety nie będzie pieniędzy na ten projekt.

Unfortunately there won't be money for this project. (pieniędzy = genitive)

Jutro nie będzie mnie w pracy.

I won't be at work tomorrow. (literally 'there won't be of me' — mnie = genitive)

This pattern is exactly parallel across the three tenses, which is why it is worth seeing together:

TenseAffirmative (nominative subject)Negative (genitive)
Presentjest czas — there's timenie ma czasu — there's no time
Pastbył czas — there was timenie było czasu — there was no time
Futurebędzie czas — there'll be timenie będzie czasu — there won't be time
💡
The negative existential — nie ma / nie było / nie będzie + genitive — is one tidy three-tense pattern. The verb collapses to a fixed singular form and the missing thing takes the genitive. Learn the trio together and the future falls out automatically.

Common Mistakes

❌ Nie będzie czas na kawę.

Incorrect — the negative existential requires the genitive, not the nominative.

✅ Nie będzie czasu na kawę.

There won't be time for coffee.

❌ Będę być w domu.

Incorrect — będę is already the future of być; you don't add the infinitive być.

✅ Będę w domu.

I'll be home.

❌ Ona będzie lekarka.

Incorrect — być takes a predicate noun in the instrumental, not the nominative.

✅ Ona będzie lekarką.

She'll be a doctor.

❌ Oni będę na imprezie.

Incorrect — the third-person plural is będą, not będę.

✅ Oni będą na imprezie.

They'll be at the party.

❌ Nie będą pieniędzy na projekt.

Incorrect — the negative existential freezes as the singular nie będzie regardless of the noun's number.

✅ Nie będzie pieniędzy na projekt.

There won't be money for the project.

Key Takeaways

  • być has one future: będę, będziesz, będzie, będziemy, będziecie, będą — no perfective alternative.
  • będę does double duty: a copula before an adjective/noun/place (będę w domu, będę gotowy, predicate nouns in the instrumental), and a tense auxiliary before an infinitive or participle (będę czytać).
  • Tell the two apart by what follows: a verb form → auxiliary; an adjective/noun/place → "to be."
  • The future existential is będzie / będą; its negative is nie będzie + genitive, parallel to nie ma and nie było.
  • Mind the spelling: będę (-ę, "I") vs. będą (-ą, "they"), and the soft będzie- in the middle forms.
