Kompostér je vedle skleníku.

Kompostér means composter or compost bin.

It is a masculine inanimate noun in Czech. In this sentence, it is in the nominative singular form because it is the subject of the sentence: Kompostér je... = The composter is...

Because the preposition vedle usually requires the genitive case.

The basic form is skleník = greenhouse, but after vedle (next to / beside), it changes to the genitive singular:

• skleník → basic dictionary form
• skleníku → genitive singular

So:

• vedle skleníku = next to the greenhouse

This is a very common pattern in Czech:

• vedle domu = next to the house
• vedle školy = next to the school
• vedle auta = next to the car

Vedle means next to, beside, or alongside.

In this sentence, vedle skleníku means next to the greenhouse.

It is a preposition, and an important thing to remember is that it is followed by the genitive case.

Je is the 3rd person singular form of the verb být = to be.

So:

• je = is

The sentence structure is:

• Kompostér = the composter
• je = is
• vedle skleníku = next to the greenhouse

So literally:

• Composter is next to greenhouse

Natural English:

• The composter is next to the greenhouse.

Unlike in some Slavic languages, Czech normally does use the present tense of to be in sentences like this.

Czech does not have articles like English a/an and the.

So kompostér can mean:

• a composter
• the composter

And skleníku can mean:

• of a greenhouse
• of the greenhouse

Which one is meant depends on context. In many basic translations, English uses the because the speaker is probably referring to a specific composter and greenhouse already known from the situation.

The neutral word order here is:

• Kompostér je vedle skleníku.

This is the most straightforward way to say The composter is next to the greenhouse.

Czech word order is more flexible than English, so other versions are possible, for example:

• Vedle skleníku je kompostér.

This still means the same thing, but it shifts the emphasis a little. It might sound more like:

• Next to the greenhouse, there is a composter or
• The composter is next to the greenhouse with focus on the location first.

So yes, the order can change, but the original sentence is the most neutral and beginner-friendly version.

A simple approximate pronunciation for an English speaker is:

• Kompostér ≈ kom-pos-TAIR
• je ≈ yeh
• vedle ≈ VED-leh
• skleníku ≈ skleh-NEE-koo

A few useful pronunciation notes:

• j in Czech sounds like English y in yes
• é is a long e sound
• í is a long ee sound
• stress in Czech is usually on the first syllable of each word:
  • KOMpostér
  • JE
  • VEDle
  • SKLEníku

Even though the stress is on the first syllable, the long vowels é and í are still pronounced long.

You can use vedle with many nouns. It is not a fixed expression.

The pattern is:

• vedle + genitive

Examples:

• vedle domu = next to the house
• vedle stromu = next to the tree
• vedle zahrady = next to the garden
• vedle garáže = next to the garage

So once you learn that vedle takes the genitive, you can build many similar sentences.

Skleník is a masculine inanimate noun.

Yes, that matters because noun gender affects:

• case endings
• adjective endings
• pronouns

Here it matters because the genitive singular ending for this noun is:

• skleník → skleníku

If you used an adjective, it would also have to match:

• vedle velkého skleníku = next to the big greenhouse

So gender is an important part of getting Czech grammar right.

Sometimes, but the meaning is slightly different.

• vedle skleníku = next to / beside the greenhouse
• u skleníku = by / near the greenhouse

So vedle usually sounds more specifically like right next to, while u can be a bit broader: near, by, at.

If the composter is directly beside the greenhouse, vedle skleníku is the better choice.

Yes. Kompostér usually refers to a compost bin, compost container, or a structure used for composting.

The exact English translation can vary depending on the object:

• a small plastic garden composter
• a wooden compost bin
• a compost container

In a simple sentence like this, composter or compost bin are both reasonable translations.

You make it negative by changing je to není:

• Kompostér není vedle skleníku.

This means:

• The composter is not next to the greenhouse.

The rest of the sentence stays the same, including skleníku, because vedle still requires the genitive.

A simple yes/no question is:

• Je kompostér vedle skleníku?

This means:

• Is the composter next to the greenhouse?

Czech often forms yes/no questions mainly by intonation or by putting the verb first in a more explicitly question-like word order.

You could answer:

• Ano, je. = Yes, it is.
• Ne, není. = No, it isn't.
