Chcę zapamiętać nowe słowa, więc w zeszycie zaznaczam akcent.

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

• chcę = I want
• The ending -ę tells you it is 1st person singular

So ja chcę is possible, but it usually adds emphasis, like I want or I do want.

Because chcieć (to want) is conjugated here in the 1st person singular present tense.

Its present-tense forms include:

• chcę = I want
• chcesz = you want
• chce = he/she/it wants
• chcemy = we want
• chcecie = you (plural) want
• chcą = they want

So chcę zapamiętać literally means I want to memorize.

This is a very common aspect question in Polish.

• pamiętać = to remember / to keep in mind (imperfective)
• zapamiętać = to memorize / to learn so that you remember (perfective)

In this sentence, the speaker wants to successfully learn and retain the new words, so zapamiętać fits better.

A rough distinction:

• Chcę pamiętać = I want to remember
• Chcę zapamiętać = I want to memorize / commit to memory

So zapamiętać focuses on the result.

It is in the accusative, but for neuter plural inanimate nouns, the accusative often looks exactly like the nominative.

Here:

• słowo = word
• słowa = words

And with the adjective:

• nowe słowa = new words

Because zapamiętać takes a direct object, new words is in the accusative plural, but the form happens to be the same as nominative plural.

So this is normal:

• nowe słowa = nominative plural / accusative plural

Because więc often introduces a result or conclusion, similar to so or therefore in English, and in Polish it is normally separated by a comma.

So:

• Chcę zapamiętać nowe słowa, więc...
• I want to memorize new words, so...

This comma is standard Polish punctuation.

Więc means so, therefore, or thus.

It shows that the second part is a consequence of the first:

• I want to memorize new words
• so I mark the stress in my notebook

It connects cause/result very naturally.

Because the preposition w changes case depending on meaning.

Here it means in or inside, describing location, so it takes the locative case.

• basic form: zeszyt = notebook
• locative after w: w zeszycie = in the notebook

So:

• w zeszycie = in the notebook

If you are talking about location, w + locative is the normal pattern.

Both can be translated as notebook, but they are not always identical in feel.

• zeszyt usually means a school-style notebook or exercise book, often with lined or squared pages
• notatnik is more like a notepad or notebook for notes

In this sentence, w zeszycie sounds very natural if the person is studying vocabulary in a school/study notebook.

Because zaznaczam is present tense imperfective, and it works well for a habitual or regular action.

• zaznaczam = I mark / I am marking
• zaznaczę = I will mark / I’ll mark

The sentence describes a usual study method:

• I want to memorize new words, so I mark the stress in my notebook.

That sounds like a repeated habit, so zaznaczam is the natural choice.

Because Polish often uses a singular noun when talking about a general feature or type of thing.

Here akcent means stress/accent placement as something the speaker marks for each word. So singular is fine because it refers to the feature itself, not to one single accent in the whole notebook.

In practice, this sounds natural:

• zaznaczam akcent = I mark the stress

You could think of it like English I mark the stress, even if you are doing it in many words.

Here akcent means word stress or stress placement, not a regional or foreign accent.

So in this sentence it means the speaker marks which syllable is stressed in a word.

For example, a learner might mark stress to help pronunciation.

Polish akcent can mean:

• accent in the sense of pronunciation style
• stress in the sense of emphasis on a syllable

In this sentence, it is clearly the second meaning.

No, Polish word order is fairly flexible, although some versions sound more neutral than others.

This sentence:

• Chcę zapamiętać nowe słowa, więc w zeszycie zaznaczam akcent.

is natural and neutral.

You could also say:

• Chcę zapamiętać nowe słowa, więc zaznaczam akcent w zeszycie.
• W zeszycie zaznaczam akcent, bo chcę zapamiętać nowe słowa.

The meaning stays similar, but the focus shifts slightly. Polish often moves elements around for emphasis or style.

Yes, chcę is a tricky word for learners.

A few helpful points:

• ch sounds like the Polish h sound
• the cluster chc- is pronounced tightly together
• final ę is a nasal vowel, but before a pause or at the end of a word it is often not pronounced as a strong full nasal vowel in careful speech the way learners expect

So learners often hear something roughly like h-tsen or khen/hen depending on speed and pronunciation details, though exact phonetics can vary.

The main thing is:

• don’t try to pronounce every letter in a very English way
• listen to native audio and repeat whole chunks: chcę zapamiętać

Yes, several.

Some words that often challenge learners:

• zapamiętać
  Watch the nasal ę and the -tać ending.

• zeszycie
  The sz sounds like English sh, and cie sounds like a softened che-type ending.

• zaznaczam
  The cz sounds like English ch, and the consonant cluster may feel dense at first.

• akcent
  The stress in Polish is usually on the second-to-last syllable, so here it is AK-cent? Actually, in Polish terms it falls on the penultimate syllable: ak-CENT.

A useful learner strategy is to practice in chunks:

• nowe słowa
• w zeszycie
• zaznaczam akcent

Yes, especially learners do this.

Polish stress is usually on the penultimate syllable, but there are exceptions, and learners may still want to mark stress to help memorize pronunciation. Even when the stress is predictable, writing it down can reinforce the sound pattern of a word.

So the sentence sounds very believable as something a student would say.
