Pošlu písemnou námitku.

Pošlu is the 1st person singular future form of the verb poslat (to send).

So:

• pošlu = I will send

This verb is perfective, which is why a simple present-looking form can express the future in Czech. With perfective verbs, Czech often uses forms like this for a completed future action.

Compare:

• poslat → pošlu = I will send / I’ll send
• posílám = I am sending / I send (imperfective, present)

Because Czech distinguishes between perfective and imperfective verbs.

• pošlu (from poslat) is perfective: it focuses on the action as a whole, as something that will be completed.
• budu posílat (from posílat) is imperfective: it would suggest an ongoing, repeated, or process-like action.

In this sentence, Pošlu písemnou námitku, the idea is usually:

• I will send a written objection
  = one complete future act

If you said Budu posílat..., it could sound more like:

• I’ll be sending...
• I’ll send repeatedly...
• I’ll be in the process of sending...

So pošlu is the natural choice here.

The dictionary forms are:

• poslat = to send
• písemný = written, in writing
• námitka = objection

The full noun phrase in dictionary form is:

• písemná námitka = written objection

In the sentence, the forms change because of grammar.

Because this phrase is the direct object of the verb pošlu (I will send), so it must be in the accusative case.

The base form is:

• písemná námitka = nominative singular

But after a verb like send, Czech uses the accusative:

• pošlu co? → písemnou námitku

For a feminine singular noun like námitka, the accusative endings are:

• noun: námitka → námitku
• adjective: písemná → písemnou

So:

• písemná námitka = a written objection
• pošlu písemnou námitku = I will send a written objection

You usually learn the gender together with the noun, but there are also useful clues.

Námitka ends in -a, which is very often a sign of a feminine noun in Czech.

That matters because adjectives have to agree with the noun in:

• gender
• number
• case

So because námitka is feminine singular, the adjective must match it:

• nominative: písemná námitka
• accusative: písemnou námitku

It can mean written, but in this context it often has the broader sense of in writing or in письмен form—in other words, not oral.

So písemná námitka can often be understood as:

• a written objection
• an objection submitted in writing

This is especially common in legal, administrative, or formal contexts.

Not exactly. Námitka most often means:

• objection
• sometimes formal objection
• in some contexts, appeal-like objection or challenge

It is common in legal, bureaucratic, and official language.

It is not always the same as complaint. A complaint in Czech might be:

• stížnost = complaint
• reklamace = complaint/claim about goods or services
• námitka = objection

So námitka is specifically more like objecting to a decision, procedure, statement, or claim.

The word order can change, because Czech word order is more flexible than English word order.

The neutral version is:

• Pošlu písemnou námitku.

But you could also hear:

• Písemnou námitku pošlu.
• Námitku pošlu písemnou.
  
  • this last one is much less neutral and depends heavily on context

Changing the word order usually changes the focus or emphasis, not the core meaning.

For example:

• Pošlu písemnou námitku. = neutral
• Písemnou námitku pošlu. = emphasis on written objection

So the original sentence is the most straightforward and neutral version.

A rough pronunciation guide:

• Pošlu ≈ POSH-loo
• písemnou ≈ PEE-sem-noh
• námitku ≈ NAA-mit-koo

A few useful points:

• Czech stress is usually on the first syllable of each word:
  • POšlu
  • PÍsemnou
  • NÁmitku
• š sounds like sh in ship
• í is a long ee sound
• á is a long a sound
• ou is a diphthong, roughly like oh said as one unit

A more approximate full pronunciation could be:

• POSH-loo PEE-sem-noh NAA-mit-koo

Yes. Pošlu námitku is grammatically correct and means:

• I will send an objection

Adding písemnou makes it more specific:

• Pošlu písemnou námitku = I will send a written objection

So whether you include it depends on whether the fact that it is written/in writing matters.

Yes, it sounds fairly formal or administrative, mostly because of the phrase písemná námitka.

The verb pošlu itself is completely normal and not especially formal. The formality mainly comes from the noun phrase:

• písemná námitka

This sounds like something you might use in:

• legal communication
• official correspondence
• complaints and procedures
• bureaucracy

In everyday conversation, people might say something simpler depending on the situation.

You make it negative by adding ne- to the verb:

• Nepošlu písemnou námitku. = I will not send a written objection.

The object stays the same here:

• písemnou námitku remains accusative

So the only change is:

• Pošlu → Nepošlu
