Podnieś proszę tę ciężką torbę.

Podnieś is the imperative singular form, used when telling one person to do something: Lift / pick up ...

The dictionary form podnieść is the infinitive, meaning to lift / to pick up.

A very rough comparison:

• podnieść = to lift
• podnieś = lift!

Because the sentence is a request or command addressed to one person, Polish uses the imperative.

Proszę makes the command sound more polite, like please in English.

So:

• Podnieś tę ciężką torbę. = a direct command
• Podnieś proszę tę ciężką torbę. = Please lift this heavy bag.

In Polish, proszę is quite flexible in position. You can often place it in different spots without changing the basic meaning:

• Proszę, podnieś tę ciężką torbę.
• Podnieś, proszę, tę ciężką torbę.
• Podnieś proszę tę ciężką torbę.

All are natural; the difference is mostly rhythm and emphasis.

Because torba is the direct object of the verb, and in Polish that means it takes the accusative case.

The basic form is:

• ta torba = this bag (nominative, used for the subject)

But after a verb like podnieść when the bag is the thing being lifted, Polish uses the accusative:

• tę torbę

So:

• ta torba = this bag is ...
• podnieś tę torbę = lift this bag

A useful pattern:

• feminine singular nominative: ta
• feminine singular accusative: tę

In everyday speech, you may also hear tą instead of tę, but in careful standard Polish, tę is the expected form here.

For the same reason as tę: the adjective has to match the noun it describes.

Since torba is:

• feminine
• singular
• in the accusative

the adjective ciężki becomes:

• ciężką

So the phrase changes like this:

• ciężka torba = a heavy bag (nominative)
• podnieś ciężką torbę = lift a heavy bag (accusative)

In Polish, adjectives agree with nouns in gender, number, and case.

Again, because torba is the direct object, so it goes into the accusative singular.

• torba = nominative
• torbę = accusative singular

Compare:

• To jest torba. = This is a bag.
• Podnieś torbę. = Lift the bag.

This is one of the most important things English speakers need to get used to in Polish: nouns change form depending on their role in the sentence.

Yes, it matters.

Podnieść is perfective. In this sentence, that gives the idea of a complete action: pick it up, raise it, get it off the ground.

That is why it works naturally in a one-time command:

• Podnieś tę torbę. = Pick up this bag.

The imperfective partner is usually podnosić:

• podnosić = to be lifting / to lift repeatedly / in a general sense

Its imperative is podnoś, which would sound different:

• Podnoś tę torbę could suggest repeated action, ongoing action, or a different context, not just one completed act.

So in a simple request to pick something up once, podnieś is the natural choice.

Yes. Polish podnieść has a range that overlaps with both lift and pick up in English.

Depending on context, it can mean:

• raise something
• lift something
• pick something up

With torbę (bag), English often prefers pick up if the bag is on the floor, but lift is also possible. Polish uses the same verb comfortably here.

Yes, Polish word order is more flexible than English because case endings show what each word is doing.

This sentence could be rearranged in several ways:

• Podnieś proszę tę ciężką torbę.
• Proszę, podnieś tę ciężką torbę.
• Tę ciężką torbę podnieś, proszę.

The default, neutral order is often:

• verb + object

Putting tę ciężką torbę earlier can add emphasis, like:

• This heavy bag, please lift it

So the given order is natural and neutral, but not the only possibility.

That is the normal order inside a Polish noun phrase.

Polish usually places:

1. demonstrative
2. adjective
3. noun

So:

• tę ciężką torbę = this heavy bag

Other orders are possible in special contexts, especially for emphasis or style, but for ordinary speech this is the standard pattern.

Not necessarily rude, but definitely more direct.

• Podnieś tę ciężką torbę. = direct command
• Podnieś proszę tę ciężką torbę. = polite request

Whether the version without proszę sounds rude depends on tone and context:

• between friends or family, it may be fine
• in a formal situation, adding proszę is safer and more polite

So proszę softens the imperative.

A few pronunciation points:

• podnieś: the ś is a soft sound, somewhat like a very soft sh with the middle of the tongue raised. English does not have an exact equivalent.
• tę and torbę: the letter ę is a nasal vowel, but in real speech its pronunciation depends on position.

In careful speech:

• tę has a nasal ending
• torbę also has ę, but sentence-final ę is often pronounced less strongly nasal in everyday speech

For learners, the key thing is:

• recognize ę as a special Polish vowel
• do not pronounce it exactly like plain e

You do not need to overdo the nasal sound; natural pronunciation varies.

The imperative verb would change.

To one person:

• Podnieś proszę tę ciężką torbę.

To more than one person:

• Podnieście proszę tę ciężką torbę.

Only the verb changes here:

• podnieś = lift! (to one person)
• podnieście = lift! (to several people)

The object phrase tę ciężką torbę stays the same.

Yes, many native speakers say tą ciężką torbę in everyday speech.

However, in standard grammar, after a transitive verb like podnieść, the recommended accusative form is:

• tę ciężką torbę

So:

• tę ciężką torbę = standard / formal / textbook-correct
• tą ciężką torbę = very common colloquial speech

As a learner, it is best to produce tę in this sentence.
