Tekst jest całkiem rozmazany.

Because tekst is the subject of the sentence: The text is quite blurred.

In Polish, the subject is usually in the nominative case, and the nominative singular form here is tekst.

Other forms would be used in other roles:

• tekstu = genitive, for example Nie ma tekstu = There is no text
• tekstem = instrumental, for example Jest tekstem piosenki = It is a song lyric/text

So in this sentence, tekst is simply the basic dictionary form because it is the thing being described.

Jest means is.

The sentence structure is very similar to English:

• Tekst = the text
• jest = is
• całkiem rozmazany = quite blurred

So literally:

• Tekst jest całkiem rozmazany = The text is quite blurred

Polish often uses być (to be) in the present tense just like English does when linking a subject to an adjective.

Usually, no in this sentence.

Polish sometimes drops forms of to be in very informal styles, headlines, notes, or poetic language, but in normal standard speech and writing, you should keep jest here:

• Tekst jest całkiem rozmazany = normal, correct
• Tekst całkiem rozmazany = sounds incomplete in standard Polish, though it might appear in very informal speech or captions

So for learners, it is best to use jest.

Całkiem can be tricky because its force depends on context.

Very often, it means something like:

• quite
• fairly
• rather

So here:

• całkiem rozmazany = quite blurred

But in some contexts, całkiem can also mean:

• completely
• entirely

For example:

• Całkiem zniknął = He disappeared completely

In your sentence, the most natural reading is quite blurred, not necessarily completely blurred.

Because it agrees with tekst, which is:

• masculine
• singular
• nominative

Polish adjectives must agree with the noun they describe in gender, number, and case.

So:

• tekst is masculine singular nominative
• therefore the adjective is rozmazany

Compare:

• tekst jest rozmazany = masculine singular
• książka jest rozmazana = feminine singular
• zdjęcie jest rozmazane = neuter singular
• teksty są rozmazane = plural

It is related to the verb rozmazać / rozmazywać, meaning to smudge, to blur, or to smear.

Rozmazany is an adjective-like form meaning:

• smudged
• blurred

So although learners can treat it as a normal adjective, it has a verbal origin.

That is very common in Polish. Many descriptive words come from verbs:

• zamknięty = closed
• zgubiony = lost
• rozmazany = blurred/smudged

In everyday use, though, you can safely think of rozmazany as an adjective.

They are similar, but not identical.

• rozmazany = blurred/smudged, often as if the image or text has been smeared or is out of focus
• niewyraźny = unclear, indistinct; broader and more general
• nieostry = unfocused, not sharp, often used for photos/images
• zamazany = obscured/smudged over, sometimes more like something has been covered or scribbled over

For text on a screen or in a photo:

• rozmazany sounds very natural
• niewyraźny is also possible, especially if you mean hard to read
• nieostry is especially common for photos or camera focus

So rozmazany gives a strong visual sense of blur or smearing.

Yes. Polish word order is more flexible than English, although the neutral order here is:

• Tekst jest całkiem rozmazany.

You might also hear:

• Całkiem rozmazany jest tekst.
• Tekst całkiem jest rozmazany. — possible, but less natural
• Rozmazany jest tekst. — more marked, stylistic, or contrastive

The basic sentence is best for learners because it sounds natural and neutral.

Word order changes usually affect emphasis, not the core meaning.

Because Polish has no articles like a or the.

So tekst can mean:

• a text
• the text
• sometimes just text

You understand which one is meant from context.

In this sentence, English would usually say the text, but Polish simply says tekst.

If you want to make it more specific, you can add a demonstrative:

• Ten tekst jest całkiem rozmazany. = This/that text is quite blurred.

A rough pronunciation guide:

• Tekst ≈ tekst
• jest ≈ yest
• całkiem ≈ TSAUW-k’yem
• rozmazany ≈ roz-ma-ZA-nih

A few useful details:

• ł sounds like English w
• cz / ć / ci are not in this sentence, but cał- begins with c, which here sounds like ts
• j sounds like English y
• stress in Polish is usually on the second-to-last syllable
  • caŁkiem
  • rozmaZAny

So the whole sentence is roughly:

• TEKST yest TSAUW-k’yem roz-ma-ZA-nih

Yes, absolutely.

• Tekst jest całkiem rozmazany. = The text is quite blurred / Text is quite blurred
• Ten tekst jest całkiem rozmazany. = This text is quite blurred or That text is quite blurred, depending on context

Adding ten makes the reference more specific. Without ten, the sentence is more neutral and general.

Yes. It sounds normal and natural.

A native speaker might also say:

• Ten tekst jest trochę rozmazany. = This text is a bit blurred
• Tekst jest niewyraźny. = The text is unclear
• Ten napis jest rozmazany. = This writing/inscription is blurred

But Tekst jest całkiem rozmazany is a perfectly natural Polish sentence.
