Makulatura jest sucha i czysta.

Because makulatura is a feminine singular noun, and Polish adjectives must agree with the noun they describe in:

• gender
• number
• case

So:

• suchy → masculine base form
• sucha → feminine singular
• czysty → masculine base form
• czysta → feminine singular

Since makulatura is feminine singular, the correct forms are sucha and czysta.

A very common clue in Polish is the ending -a. Most nouns ending in -a are feminine, including makulatura.

So the sentence behaves like this:

• makulatura = feminine singular noun
• jest = is
• sucha i czysta = feminine singular adjectives

Be aware that there are exceptions in Polish, but makulatura is a regular feminine noun.

Jest is the 3rd person singular form of być (to be), so it means is.

The structure is:

• Makulatura = subject
• jest = verb
• sucha i czysta = description

So grammatically, this is the same kind of structure as:

• Papier jest biały = The paper is white
• Woda jest zimna = The water is cold

Sometimes yes, especially in signs, labels, instructions, or very concise style.

For example, on a recycling notice you might see:

• Makulatura sucha i czysta

This has the sense of Waste paper: dry and clean or Waste paper should be dry and clean.

But in a normal full sentence, Makulatura jest sucha i czysta is the standard complete form.

It is in the nominative case, because it is the subject of the sentence.

You can think of it as:

• Who/what is dry and clean?
• Makulatura

The adjectives are also in nominative feminine singular because they match the subject.

I is the normal Polish word for and when simply joining two items.

So:

• sucha i czysta = dry and clean

This is the most natural choice here.

Learners sometimes confuse i with a. In Polish:

• i usually just adds one thing to another
• a often contrasts or shifts topic, like and/but/as for

So here i is correct because both adjectives describe the same noun without contrast.

The most neutral word order is:

• Makulatura jest sucha i czysta.

But Polish word order is more flexible than English, so other orders are possible for emphasis or style, for example:

• Sucha i czysta jest makulatura.
• Makulatura sucha i czysta jest rzadkością. (in a longer sentence)

Still, for a learner, the original sentence is the best standard pattern to use.

Their dictionary forms are:

• suchy = dry
• czysty = clean

These are usually listed in the masculine singular nominative form in dictionaries.
When they describe a feminine noun like makulatura, they change to:

• suchy → sucha
• czysty → czysta

A simple approximate pronunciation for an English speaker is:

• mah-koo-lah-TOO-rah yest SOO-hah ee CHIH-stah

A few helpful notes:

• Polish stress is usually on the second-to-last syllable
• rz in jest is not pronounced like English r
• cz sounds roughly like ch in chop
• sz in sucha sounds like sh

A more careful breakdown:

• Makulatura → ma-ku-la-TU-ra
• jest → yest
• sucha → SU-cha with ch like a rough h
• i → ee
• czysta → CZYS-ta

Usually makulatura refers to waste paper, scrap paper, or paper collected for recycling rather than just any paper in general.

So this sentence sounds especially natural in contexts like:

• recycling instructions
• waste sorting rules
• collection guidelines

That is why describing it as dry and clean makes good sense.

Yes. That would also be grammatically correct.

Both mean the same thing:

• Makulatura jest sucha i czysta
• Makulatura jest czysta i sucha

The difference is only the order of the adjectives. Often the original order may sound slightly more natural in practical instructions, but both are fine.

Grammatically, it is a statement: The waste paper is dry and clean.

But in real-life contexts, especially on signs or recycling instructions, it may function more like a rule or requirement, meaning something like:

• the waste paper should be dry and clean
• only dry, clean waste paper belongs here

So the exact interpretation depends on context, even though the grammar is simply a present-tense statement.
