Dziś mam dużo pracy w biurze.

In Polish, subject pronouns are often omitted because the verb form already shows who is doing the action.

• mam = I have
• so ja mam is possible, but usually just mam is enough

You would add ja only for emphasis, contrast, or clarity:

• Ja mam dużo pracy, a on nie ma. = I have a lot of work, but he doesn’t.

So Dziś mam dużo pracy w biurze sounds natural and normal.

Dziś means today. It is essentially the same as dzisiaj.

• dziś = today
• dzisiaj = today

Both are very common. Dziś is a little shorter and can sound slightly more concise or literary in some contexts, but in everyday speech both are fine.

So these mean the same thing:

• Dziś mam dużo pracy w biurze.
• Dzisiaj mam dużo pracy w biurze.

After dużo (a lot of / much), Polish normally uses the genitive case.

So:

• base form: praca = work
• genitive form: pracy

That is why you say:

• dużo pracy = a lot of work

This is a very common pattern in Polish:

• dużo czasu = a lot of time
• dużo ludzi = a lot of people
• dużo pieniędzy = a lot of money

So the sentence uses normal grammar: mam dużo pracy = I have a lot of work.

Because pracy is the genitive singular form of praca.

The dictionary form is:

• praca = work

But in this sentence, it follows dużo, which requires the genitive:

• dużo pracy

This change is not random; it is part of the noun’s declension pattern.

A simplified pattern:

• nominative: praca
• genitive: pracy
• locative: pracy (same form here, though not used in this sentence)

For learners, the key thing to remember is: dużo + genitive.

The preposition w often means in or at, and when it refers to location, it requires the locative case.

So:

• biuro = office
• w biurze = in the office / at the office

This is another very common Polish pattern:

• w domu = at home / in the house
• w szkole = at school
• w sklepie = in the shop
• w biurze = in the office

So w biurze is the correct form because the sentence is talking about location.

It can mean either, depending on context.

Literally, w biurze is in the office, but in natural English translation it may be:

• in the office
• at the office

In this sentence, both make sense:

• Today I have a lot of work in the office.
• Today I have a lot of work at the office.

English chooses between in and at more flexibly, while Polish simply uses w biurze.

Here praca means work in the sense of tasks, duties, or workload.

So mam dużo pracy means:

• I have a lot of work to do
• I’m very busy with work

It does not usually mean I have a job. For I have a job, Polish more naturally says:

• Mam pracę. = I have a job.

So compare:

• Mam pracę. = I have a job.
• Mam dużo pracy. = I have a lot of work.

Yes, Polish word order is more flexible than English, although some orders sound more natural than others.

The neutral sentence is:

• Dziś mam dużo pracy w biurze.

Other possible orders include:

• Mam dziś dużo pracy w biurze.
• W biurze mam dziś dużo pracy.
• Dużo pracy mam dziś w biurze.

These are grammatical, but they shift emphasis.

For example:

• Dziś at the beginning emphasizes today
• W biurze at the beginning emphasizes in the office
• Dużo pracy at the beginning emphasizes a lot of work

For learners, the original order is a very good neutral model.

Polish does not have articles like a, an, and the.

So where English says:

• a lot of work

Polish simply says:

• dużo pracy

This is normal throughout the language. Polish expresses definiteness and indefiniteness through context, not articles.

Yes, very often.

In English, we distinguish:

• much work
• many books
• a lot of work
• a lot of books

In Polish, dużo can work with both types:

• dużo pracy = a lot of work
• dużo książek = a lot of books

So dużo is a very useful word for learners.

A rough English-friendly guide:

• Dziś ≈ jish (with a soft zh/sh sound)
• mam = mahm
• dużo ≈ doo-zho
• pracy ≈ pra-tsih
• w = v
• biurze ≈ byoo-zhe

A more careful breakdown:

• dziś sounds like one syllable
• dużo has stress on the first syllable: DU-żo
• pracy has stress on the first syllable: PRA-cy
• biurze has stress on the first syllable: BIU-rze

In Polish, stress is usually on the second-to-last syllable of the word, and that rule works here.

Yes, it is grammatically present tense:

• mam = I have

But just like in English, it can describe a current situation for today, including what is still ahead of you.

So Dziś mam dużo pracy w biurze can mean:

• Today I have a lot of work in the office.
• Today I’m going to have a lot of work in the office.

The exact timing depends on context.

Grammatically you could, but it sounds repetitive and less natural.

• w pracy = at work
• w biurze = in the office / at the office

So if you want to say you have a lot of work at your workplace in general, w pracy is often better:

• Dziś mam dużo pracy w pracy.

But because pracy appears twice, it sounds a bit awkward. Native speakers may prefer rephrasing, for example:

• Dziś mam dużo pracy.
• Dziś będę bardzo zajęty w pracy.
• Dziś mam dużo pracy w biurze.

So the original sentence is natural and avoids that repetition.
