Kolem nábytku je voda.

Kolem means around or around the area of.

In this sentence, kolem is a preposition, and it requires the genitive case. That is why nábytek changes to nábytku.

So the pattern is:

kolem + genitive

Examples:

• kolem domu = around the house
• kolem auta = around the car
• kolem nábytku = around the furniture

Because kolem takes the genitive case, and nábytek has to appear in its genitive form.

The dictionary form is:

• nábytek = furniture

Its genitive singular is:

• nábytku

So:

• kolem nábytek = incorrect
• kolem nábytku = correct

This is one of the most important things to get used to in Czech: prepositions often force a particular case.

Grammatically, nábytek is singular.

It works a lot like English furniture: it refers to a collection of things, but the noun itself is singular.

So:

• ten nábytek = that furniture
• nábytek je drahý = the furniture is expensive

That is why in this sentence you do not use a plural verb.

Because voda is singular.

• voda = water
• je = is

So je voda means there is water or literally is water.

If the subject were plural, you would use jsou:

• Kolem nábytku jsou lahve. = There are bottles around the furniture.

Here, though, water is singular, so je is correct.

Both are possible, but the word order changes the focus a little.

• Kolem nábytku je voda.
  This puts more attention on the location first: around the furniture, there is water.

• Voda je kolem nábytku.
  This starts with water as the topic: the water is around the furniture.

Czech word order is more flexible than English, and it often reflects what is already known and what is new or emphasized.

So the given sentence sounds very natural if the speaker wants to highlight the place first.

Not necessarily completely, but it does suggest that the water is around it/in the area surrounding it.

In natural English, around the furniture can mean surrounding it or simply in the space near and around it. Czech kolem works similarly.

So this sentence does not automatically mean there is water on every side in a perfect circle. It just means the water is around the furniture.

Yes. Okolo is very similar to kolem, and in many contexts they can both mean around.

So:

• Kolem nábytku je voda.
• Okolo nábytku je voda.

Both are understandable and natural.

In everyday use, kolem is extremely common. Learners will often meet both forms, but for this sentence, kolem is perfectly standard.

Yes, very often that is the best way to understand it.

Czech does not always need a direct equivalent of English there is / there are. A sentence like:

• Kolem nábytku je voda

can naturally correspond to:

• There is water around the furniture

Literally, Czech says something closer to:

• Around the furniture is water

So if you are translating in your head, it is helpful to remember that Czech often expresses existence without a separate word like English there.

You usually know from two things:

1. The preposition
   Kolem requires the genitive.

2. The noun form
   For nábytek, the genitive singular is nábytku.

So even if -u can appear in other case forms with other nouns, here the preposition tells you what case it must be.

This is a common strategy in Czech:

• first identify the preposition
• then determine which case it governs
• then check the noun ending

A simple learner-friendly pronunciation is:

KO-lem NAA-bit-ku ye VO-da

A slightly more accurate guide:

• kolem = KO-lem
• nábytku = NAA-bit-koo
• je = ye
• voda = VO-da

A few useful notes:

• á is a long vowel, so ná- is longer than a short a
• y in nábytku is not the same as English ee, but beginners can approximate it lightly
• j in Czech is pronounced like English y in yes

Usually nábytek means furniture as a mass/collective noun, so it often refers to furniture as a group rather than a single item.

So Kolem nábytku je voda most naturally means:

• there is water around the furniture

If you wanted to refer to one specific piece of furniture, Czech would often use a more specific noun, such as:

• kolem stolu = around the table
• kolem skříně = around the wardrobe
• kolem židle = around the chair

So while the sentence is grammatical, its most natural reading is about furniture collectively rather than one single item.
