Płacę abonament dzisiaj.

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

Here, płacę means I pay / I am paying, so ja is not necessary.

You could say Ja płacę abonament dzisiaj, but that usually adds emphasis, like I’m the one paying today or I am paying today.

Płacę is the 1st person singular present tense form of płacić (to pay).

So:

• płacę = I pay / I am paying

Polish present tense often covers both English simple present and present continuous, so the exact translation depends on context.

Because it is the direct object of the verb płacę, so it is in the accusative case.

However, abonament is a masculine inanimate noun, and for many masculine inanimate nouns, the accusative singular looks exactly the same as the nominative singular.

So:

• nominative: abonament
• accusative: abonament

That is why you do not see a change here.

Abonament usually means a subscription, subscription fee, or sometimes a regular paid plan/service.

Depending on context, it could refer to things like:

• a phone plan
• internet service
• a gym membership
• a streaming subscription
• a monthly fee for some service

So in real life, the exact English translation may vary: subscription, fee, membership, or plan.

Because Polish has no articles.

English uses:

• a subscription
• the subscription

Polish simply says abonament, and the exact meaning is understood from context.

So abonament can mean:

• a subscription
• the subscription
• sometimes just subscription fee

Dzisiaj means today. It is an adverb of time.

It tells you when the payment happens.

Polish does not need a preposition here, so you simply say:

• dzisiaj = today

Not something like in today or on today.

Yes, Polish word order is much more flexible than English word order.

Płacę abonament dzisiaj is correct, but you could also say:

• Dzisiaj płacę abonament
• Abonament płacę dzisiaj

These versions are all grammatical, but they can shift the emphasis.

For example:

• Dzisiaj płacę abonament puts more focus on today
• Płacę abonament dzisiaj sounds natural and neutral, with today added at the end
• Abonament płacę dzisiaj sounds more marked, as if contrasting the subscription with something else

Yes, but the difference is small.

Both mean today.

• dzisiaj is a little fuller and very common in everyday speech
• dziś is shorter and also very common, but can sound slightly more compact or sometimes a bit more literary depending on context

In this sentence, both are fine:

• Płacę abonament dzisiaj
• Płacę abonament dziś

A helpful approximation is:

PWA-tseh ah-bo-NAH-ment JEE-shai

A few important pronunciation points:

• ł sounds like English w
• c sounds like ts
• ę is a nasal vowel; at the end of a word like płacę, many learners can approximate it as -eh at first
• dz in dzisiaj starts as a voiced sound like dz
• si before a vowel gives a soft sh-like sound, so dzisiaj sounds roughly like jee-shai

You do not need a perfect nasal ę immediately; being understood matters more at first.

Yes, but it means something different.

• Płacę abonament dzisiaj = I’m paying / I pay the subscription today
• Zapłacę abonament dzisiaj = I will pay the subscription today

The difference is mainly aspect and time reference:

• płacić is imperfective, often used for an ongoing action, a general action, or a present-time statement
• zapłacić is perfective, and perfective verbs do not have a true present meaning in Polish; their present forms usually refer to the future

So if you mean the payment is happening now or as part of today’s current action, płacę works well. If you mean a future completed payment, zapłacę is more suitable.

Yes.

Polish present tense often covers both ideas:

• simple present: I pay
• present continuous: I am paying

So Płacę abonament dzisiaj can mean either:

• I pay the subscription today
• I’m paying the subscription today

Context tells you which is more natural.

Yes, it is grammatical and understandable, but in everyday speech people might also use slightly different phrasing depending on context.

Common alternatives include:

• Dzisiaj płacę abonament.
• Płacę dziś abonament.
• Dziś opłacam abonament.

The most natural version often depends on what is being emphasized:

• the time (today)
• the action (paying)
• the thing being paid (subscription)

So the sentence you have is perfectly fine, even if another word order may sound more natural in some situations.
