Chcę nadać przesyłkę.

A good approximate pronunciation is:

• Chcę → h-tsen or khsen
• nadać → NA-dach (the final ć is a soft ch sound)
• przesyłkę → pshe-SIUW-keh

A more natural connected pronunciation is something like:

Htsen NA-dach pshe-SIUW-keh

A few useful notes:

• ch in Polish is like a hard h.
• cz would sound like English ch, but here you have chc, which can feel awkward at first.
• ę is a nasal vowel. In chcę, many learners can safely approximate it as en.
• Stress in Polish usually falls on the second-to-last syllable:
  • CHCĘ
  • NA-dać
  • prze-SYŁ-kę

Chcę means I want.

It comes from the verb chcieć = to want.

The ending -ę marks 1st person singular present tense, so:

• chcę = I want
• chcesz = you want
• chce = he/she/it wants

This is why the sentence starts with Chcę: the subject I is already built into the verb, so Polish usually does not need a separate pronoun ja.

Here nadać means to send off, to mail, or more literally to dispatch a parcel/shipment through a postal or courier service.

In this context, nadać przesyłkę is a very standard expression, especially at:

• a post office
• a parcel shop
• a courier point

So Chcę nadać przesyłkę is a very natural way to say you want to send a package.

Important: nadać has several meanings in Polish depending on context, but with przesyłkę it specifically means to send/mail/dispatch.

Because Polish commonly uses the pattern:

chcę + infinitive = I want to + verb

So:

• Chcę nadać = I want to send
• Chcę kupić = I want to buy
• Chcę zapytać = I want to ask

This works very much like English want to do something.

Because przesyłka is the direct object of the verb, so it goes into the accusative case.

The dictionary form is:

• przesyłka = shipment / parcel / consignment

But after a verb like nadać, you need the accusative:

• przesyłkę

So:

• przesyłka = nominative, the basic form
• przesyłkę = accusative, used here as the thing being sent

This is a very common pattern in Polish:

• Mam książkę = I have a book
• Kupuję kawę = I’m buying coffee
• Nadaję przesyłkę / Chcę nadać przesyłkę = I’m sending / I want to send a shipment

They are close, but not always identical.

• przesyłka = a general shipment / postal item / consignment
• paczka = a package / parcel

Przesyłka is a bit broader and often more official or service-related. It can refer to something being sent through the postal or courier system in general.

Paczka is more everyday and concrete.

At a post office, you may hear both, but:

• nadać przesyłkę sounds especially standard/formal
• wysłać paczkę sounds very natural in everyday speech

Both can often be translated as to send a package, but they feel slightly different.

• nadać przesyłkę

  • more official/service language
  • common at the post office or courier desk
  • focuses on formally dispatching a postal item

• wysłać paczkę

  • more general everyday language
  • very common in normal conversation
  • simply means to send a package

So if you are speaking to staff at a post office, Chcę nadać przesyłkę sounds very natural and appropriate.

This is about aspect, which is very important in Polish verbs.

• nadawać = imperfective
• nadać = perfective

Very roughly:

• imperfective focuses on the process, repetition, or general activity
• perfective focuses on a completed action or a single whole event

With chcę, both aspects are possible in some situations, but they mean slightly different things:

• Chcę nadać przesyłkę
  = I want to send this shipment / get it sent off
  = one complete action

• Chcę nadawać przesyłki
  = I want to send shipments regularly / as an ongoing activity

In your sentence, nadać is used because the speaker usually means one specific act of sending one parcel.

Yes, you can. It is grammatically correct.

But normally Polish drops subject pronouns when they are not needed, because the verb already shows the person:

• Chcę already means I want

So:

• Chcę nadać przesyłkę = neutral, natural
• Ja chcę nadać przesyłkę = more emphatic, like I want to send the parcel

You might use ja if:

• you are contrasting yourself with someone else
• you want emphasis
• you are correcting someone

Example:

• On chce odebrać paczkę, a ja chcę nadać przesyłkę.
  = He wants to pick up a package, and I want to send one.

Yes. Polish word order is more flexible than English because endings carry a lot of grammatical information.

The most neutral order is:

• Chcę nadać przesyłkę.

But you could also hear:

• Przesyłkę chcę nadać.
• Nadać chcę przesyłkę.

These versions are more marked and usually used for emphasis, contrast, or style.

For a learner, the best default is:

• Chcę nadać przesyłkę.

It is the most natural and safest choice in ordinary conversation.

Yes, it is polite enough and completely natural.

Chcę nadać przesyłkę. is a normal, practical thing to say at a service counter.

If you want to sound a bit softer or more polite, you could also say:

• Chciałbym nadać przesyłkę. = I would like to send a shipment.
  if the speaker is male
• Chciałabym nadać przesyłkę. = I would like to send a shipment.
  if the speaker is female

These are often felt as slightly more courteous than plain Chcę.

A few very useful ones are:

From chcieć:

• chcę = I want
• chcesz = you want
• chce = he/she/it wants

From nadać / nadawać:

• nadać = to send off, to dispatch
• nadawać = to be sending, to send regularly

From przesyłka:

• przesyłka = shipment / parcel item
• przesyłkę = shipment / parcel item in the accusative
• przesyłki = shipments / also some singular case forms depending on context

Useful service phrases:

• Chcę nadać paczkę. = I want to send a package.
• Chcę odebrać przesyłkę. = I want to collect a shipment.
• Gdzie mogę nadać przesyłkę? = Where can I send a shipment?
