Nájemce napsal pronajímateli.

Nájemce is in the nominative singular, which is the case normally used for the subject of the sentence.

So in Nájemce napsal pronajímateli, nájemce is the person who performed the action of writing.

A useful extra point: even though nájemce ends in -e, it is still a masculine animate noun. Czech gender is not determined only by the ending.

Because pronajímateli is the dative singular form of pronajímatel.

The verb napsat often works with:

• the writer in the nominative
• the message as a direct object, if one is mentioned
• the recipient in the dative

So Czech says, effectively, wrote to the landlord by putting landlord into the dative:

• pronajímatel = landlord
• pronajímateli = to the landlord

Yes. In this sentence, the dative ending does the job that to does in English.

English uses a preposition:

• wrote to the landlord

Czech often uses the dative case instead:

• napsal pronajímateli

So there is no separate word for to here; the case ending already expresses that meaning.

Yes. Pronajímateli and pronajímatelovi are both possible dative singular forms.

For many masculine animate nouns, Czech allows both:

• učiteli / učitelovi
• pronajímateli / pronajímatelovi

In practice:

• pronajímateli may sound a bit more compact or formal
• pronajímatelovi may sound a bit more explicit or natural in some contexts

Both are standard.

Because napsal is the masculine singular past tense form.

The subject nájemce is masculine, so the verb agrees with it:

• nájemce napsal = a male tenant wrote
• nájemkyně napsala = a female tenant wrote

In Czech past tense, the verb form shows gender in the singular.

In the 3rd person past tense, Czech does not use an overt auxiliary.

Compare:

• napsal jsem = I wrote
• napsal jsi = you wrote
• napsal = he wrote

So napsal by itself is a complete 3rd person singular past form.

This is a question of aspect.

• napsat = perfective: to write, as a completed act
• psát / psal = imperfective: to be writing, to write in an ongoing or repeated sense

So:

• Nájemce napsal pronajímateli. = the tenant wrote to the landlord, and the act is viewed as completed.
• Nájemce psal pronajímateli. = the tenant was writing to the landlord / wrote to the landlord, with focus on the process or ongoing activity rather than completion.

No. Czech word order is fairly flexible because case endings show grammatical roles.

This sentence has a neutral, straightforward order:

• Nájemce napsal pronajímateli.

But other orders are also possible, with different emphasis:

• Pronajímateli napsal nájemce. = emphasizes to the landlord or contrasts the writer
• Napsal pronajímateli nájemce. = can sound like an answer to Who wrote to the landlord?

So the basic meaning stays similar, but the information focus changes.

Czech has no articles like English a/an/the.

So nájemce can mean:

• a tenant
• the tenant

and pronajímateli can mean:

• to a landlord
• to the landlord

Which one is meant depends on context. In many situations, the meaning is obvious from the situation or previous sentences.

It is common, but it can sound a bit more formal or legal than some learners expect.

A very common everyday word is:

• nájemník = tenant

But nájemce is also very common, especially in contracts, official language, and housing-related contexts.

So this sentence sounds natural, especially in a more formal or neutral register.

A rough guide:

• nájemce ≈ NAA-yem-tseh
• napsal ≈ NAP-sal
• pronajímateli ≈ PRO-na-YEE-ma-teh-li

A few key pronunciation points:

• Czech stress is usually on the first syllable of each word.
• á and í mark long vowels, not stress.
• j is pronounced like English y.
• c is pronounced ts.

So although jí in pronajímateli has a long vowel, the stress is still at the start: PRO-na-jí-ma-te-li.
