Chci připojit dokovací stanici k notebooku.

Because Czech verbs usually already show who the subject is.

• chci = I want
• So já is not necessary unless you want emphasis or contrast.

Compare:

• Chci připojit dokovací stanici k notebooku. = neutral
• Já chci připojit dokovací stanici k notebooku. = I want to connect the docking station to the laptop

So omitting the subject pronoun is completely normal in Czech.

Czech often uses chtít + infinitive, just like English uses want + to + verb.

• chci = I want
• připojit = to connect / attach

So the structure is:

• chci
  • připojit
• literally: I want to connect

This is a very common pattern:

• Chci jít. = I want to go.
• Chci koupit kabel. = I want to buy a cable.

Připojit is the infinitive form of the verb, and it is a perfective verb.

That matters because Czech often distinguishes:

• perfective = completing an action, getting it done
• imperfective = the process, repetition, or ongoing action

Here, připojit suggests a single completed act: connecting the docking station.

A related imperfective verb is připojovat.

Very roughly:

• Chci připojit dokovací stanici... = I want to connect it / get it connected
• Chci připojovat dokovací stanici... would sound less natural here unless you mean repeated or ongoing connecting

So in this sentence, the perfective verb is the natural choice.

Because dokovací stanici is the direct object of připojit, so it is in the accusative case.

The base form is:

• dokovací stanice = docking station

But in the accusative singular, stanice changes to stanici.

So:

• nominative: dokovací stanice
• accusative: dokovací stanici

The adjective dokovací stays the same here, but the noun changes.

This is normal for many feminine nouns of this type.

Because the preposition k requires the dative case.

So:

• notebook = base form
• k notebooku = to the laptop / to the notebook

This is a very important Czech pattern:

• k + dative

Examples:

• k autu = to the car
• k počítači = to the computer
• k telefonu = to the phone

So k notebooku is required by the preposition k.

In this sentence, k means something like to.

With připojit, it marks what something is being connected to:

• připojit něco k něčemu = to connect something to something

So the pattern is:

• dokovací stanici = the thing being connected
• k notebooku = the thing it is being connected to

This verb commonly works with that structure.

Examples:

• Připojil jsem tiskárnu k počítači. = I connected the printer to the computer.
• Připoj kabel k monitoru. = Connect the cable to the monitor.

Not in this sentence.

With připojit in the sense of connecting one device to another, Czech normally uses:

• k + dative

So:

• připojit dokovací stanici k notebooku = correct

But:

• do notebooku
• na notebook

would suggest different spatial meanings and would not be the normal wording for device connection here.

So this is something best learned as a pattern:

• připojit něco k něčemu

Because adjectives in Czech agree with the noun they describe.

Here:

• dokovací describes stanici
• the dictionary form is dokovací stanice

When the noun changes case, the adjective must match it as needed.

In this specific phrase:

• nominative: dokovací stanice
• accusative: dokovací stanici

The adjective dokovací happens to look the same here, but it is still agreeing with the noun.

So even when the form does not visibly change, agreement is still there.

Czech word order is much more flexible than English word order.

The sentence:

• Chci připojit dokovací stanici k notebooku.

is a neutral, natural order.

But other orders are also possible, depending on emphasis:

• Dokovací stanici chci připojit k notebooku.
• K notebooku chci připojit dokovací stanici.

These do not usually change the basic meaning, but they can shift the focus:

• what I want to connect
• what I want to connect it to

For learners, the original order is a very good default.

Yes, but then the grammar changes because the roles change.

Your sentence means:

• the docking station is the thing being connected
• the laptop is the target

If you reverse that, you would say:

• Chci připojit notebook k dokovací stanici.

Now:

• notebook is the direct object
• k dokovací stanici is the dative phrase after k

So Czech shows the roles through case endings, not just word position.

It is a commonly used loanword in Czech, especially for a laptop computer.

It behaves like a Czech masculine noun, so it takes Czech case endings:

• notebook
• notebooku
• notebookem, etc.

Czech also uses laptop, and usage can vary by speaker or context, but notebook is completely normal.

For learners, the important thing is that even borrowed words usually decline in Czech.

From the form and from the sentence structure.

Here:

• stanici is accusative singular
• plural would look different

For example, plural accusative would be:

• dokovací stanice or another plural form depending on context and noun type

In this sentence, dokovací stanici clearly means one docking station.

So even though English often relies mostly on word order and articles, Czech often tells you number and grammatical role through endings.

It is natural and correct, but real-life Czech can vary a bit.

A speaker might also say:

• Chci připojit dokinu k notebooku.
• Potřebuju připojit dokovací stanici k notebooku.

depending on style and context.

But your sentence is a very good standard version:

• clear
• grammatical
• natural

So it is a useful model for learning the pattern:

• chtít + infinitive
• připojit něco k něčemu
