Zarządca zarządza nieruchomością.

Because they are closely related words built from the same root.

• zarządca = a person who manages; a manager / administrator
• zarządza = manages / is managing

This is similar to English pairs like manager and manages. Polish often forms nouns and verbs from the same base, so this kind of resemblance is very common.

Grammatically, zarządca is a masculine personal noun, even though it ends in -a.

That may feel strange to an English speaker, but Polish has a group of masculine nouns like this, especially for professions or people, for example:

• mężczyzna = man
• kierowca = driver
• sprzedawca = seller
• zarządca = manager / administrator

So you treat zarządca as masculine in agreement, for example in the past tense or with adjectives:

• Ten zarządca był zajęty. = This manager was busy.

In real life, the word can also be used as a job title for a woman in some contexts, but grammatically the noun itself is of the masculine-personal type.

zarządza is:

• 3rd person singular
• present tense
• from the imperfective verb zarządzać

So it means he/she manages, he/she is managing, or more generally manages.

Because Polish present tense of an imperfective verb can cover both habitual and ongoing meaning, the exact English translation depends on context:

• Zarządca zarządza nieruchomością. could correspond to The manager manages the property or The manager is managing the property.

Because the verb zarządzać requires the instrumental case for the thing being managed.

The basic dictionary form is:

• nieruchomość = property / real estate

But after zarządzać, it changes to instrumental singular:

• nieruchomością

So:

• zarządzać nieruchomością = to manage a property

This is something you usually just have to learn together with the verb: not only what the verb means, but also what case it takes.

With the meaning to manage, yes, that is the normal pattern:

• zarządzać firmą = to manage a company
• zarządzać budynkiem = to manage a building
• zarządzać nieruchomością = to manage a property

So zarządzać nieruchomość would be incorrect in this meaning.

This is a very important habit in Polish: learn verbs together with the case they govern.

nieruchomość is a feminine noun.

Some useful forms are:

• nominative singular: nieruchomość
• genitive singular: nieruchomości
• dative singular: nieruchomości
• accusative singular: nieruchomość
• instrumental singular: nieruchomością
• locative singular: nieruchomości

Its ending in -ść is very typical of many feminine nouns in Polish.

It can do either, depending on context.

• In many sentences, nieruchomość means a property or a piece of real estate.
• In broader contexts, it can refer to real estate as a category.

In this sentence, the singular form most naturally suggests a property or the property being managed.

Polish does not have articles like English a and the.

So Zarządca zarządza nieruchomością can correspond to different English versions depending on context, such as:

• The manager manages the property.
• A manager manages a property.
• The property manager manages the property.

Polish usually leaves that kind of definiteness to context rather than marking it with an article.

Yes. Polish word order is more flexible than English because the endings show grammatical relationships.

The most neutral order here is:

• Zarządca zarządza nieruchomością.

But you could also say:

• Nieruchomością zarządza zarządca.

That version puts more focus on nieruchomością and can sound like As for the property, the manager manages it or It is the manager who manages the property, depending on context.

So the meaning stays broadly the same, but the emphasis changes.

Here are the main singular forms:

• nominative: zarządca
• genitive: zarządcy
• dative: zarządcy
• accusative: zarządcę
• instrumental: zarządcą
• locative: zarządcy
• vocative: zarządco

This is a good example of a masculine-personal noun ending in -a: it behaves partly like a feminine noun in its endings, but it is still grammatically masculine.

Not always. In many contexts, zarządca suggests an administrator, property manager, estate manager, or someone officially responsible for managing something such as a building, property, or institution.

So in a sentence with nieruchomością, it feels especially natural, because the combination strongly suggests a real-estate or building-management context.

A few useful pronunciation points:

• rz is pronounced like zh in measure
• ą before a consonant is often heard roughly like on or om
• ść is a soft sound somewhat like shch
• stress in Polish usually falls on the penultimate syllable

So the stress is roughly here:

• za-RZĄD-ca
• za-RZĄ-dza
• nie-ru-cho-MO-ścią

A rough English-friendly approximation would be something like:

• zarządca ≈ za-ZHONT-sa
• zarządza ≈ za-ZHON-dza

The last word, nieruchomością, is harder to approximate neatly in English, but the most important things are the stress on MO and the soft ending -ścią.
