Klávesnice je pod monitorem.

Because pod can require different cases, and here it means under in a location sense, so it takes the instrumental case.

• basic form: monitor
• instrumental singular: monitorem

So:

• pod monitor — incorrect here
• pod monitorem — correct

A very common Czech pattern is:

• je pod + instrumental = is under

In Czech, some prepositions change case depending on meaning.

With pod:

• pod + instrumental = location, meaning under
• pod + accusative = movement toward a position under something

So in this sentence:

• Klávesnice je pod monitorem. = the keyboard is under the monitor
  → static position
  → instrumental

Compare:

• Dám klávesnici pod monitor. = I will put the keyboard under the monitor
  → movement
  → accusative

This location vs. movement distinction is very important in Czech.

Klávesnice is in the nominative case because it is the subject of the sentence.

The structure is:

• Klávesnice = subject
• je = is
• pod monitorem = prepositional phrase describing location

So klávesnice stays in its basic dictionary form here.

Klávesnice is feminine.

You can see that from its ending and from how it behaves in declension. Many Czech nouns ending in -e are feminine, and klávesnice belongs to that group.

This matters because gender affects:

• adjectives
• pronouns
• past tense forms
• some number patterns

For example, if you later replace it with it, you would refer to klávesnice with feminine forms in Czech.

Je is the 3rd person singular of být (to be) and means is.

In standard Czech, when you make a normal present-tense sentence like this, you usually keep je:

• Klávesnice je pod monitorem.

Omitting it would usually sound incomplete or nonstandard in a simple sentence like this.

Czech sometimes leaves out forms of to be in headlines, notes, or very informal styles, but for a normal learner sentence, je should stay.

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

So:

• klávesnice can mean a keyboard or the keyboard
• monitor can mean a monitor or the monitor

The exact meaning depends on context.

In this sentence, English uses the keyboard and the monitor, but Czech simply says:

• Klávesnice je pod monitorem.

This is completely normal.

The basic neutral word order here is:

• Klávesnice je pod monitorem.

But Czech word order is more flexible than English because case endings show grammatical roles.

You can also say:

• Pod monitorem je klávesnice.

This still means the same thing, but the focus is slightly different. It may sound like you are answering What is under the monitor?

So:

• Klávesnice je pod monitorem. = neutral statement
• Pod monitorem je klávesnice. = location-first, often more context-driven

Approximate pronunciation:

• klávesnice ≈ KLAA-vess-nyi-tseh
• monitorem ≈ MO-nyi-to-rem

A few useful pronunciation points:

• á is a long vowel
• e at the end is pronounced, not silent
• c in Czech is pronounced like ts
• r is rolled or tapped
• stress in Czech is usually on the first syllable

So:

• KLÁ-ves-ni-ce
• MO-ni-to-rem

The accent mark in á shows that the vowel is longer.

So:

• a = short
• á = long

In Czech, vowel length can matter, and it is important to notice and pronounce it if possible.

In klávesnice, the first syllable has a long vowel:

• klá-

Even if your pronunciation is not perfect yet, it is good to be aware that the length is part of the correct form.

Yes, it is completely normal and natural.

The pattern is very common:

• pod stolem = under the table
• pod oknem = under the window
• pod postelí = under the bed
• pod monitorem = under the monitor

So once you learn pod + instrumental for location, you can use it in many everyday situations.

Not in standard Czech.

Pod monitorom is not the standard Czech form. The correct instrumental singular in Czech is:

• monitor → monitorem

The form monitorom may look familiar if you know or have seen Slovak, but in Czech the correct ending here is -em:

• pod monitorem

So for Czech, use monitorem.
