Wybieram fioletową torbę.

Because Polish often leaves out subject pronouns when the verb already makes the subject clear.
Wybieram already means I choose / I am choosing, so ja is not necessary.

You can add ja if you want emphasis, for example:

• Ja wybieram fioletową torbę = I’m the one choosing the purple bag

Wybieram is the 1st person singular present tense form of the verb wybierać.

So grammatically it means:

• I choose
• I am choosing

Polish present tense often covers both the simple present and the present continuous, and context tells you which is more natural.

Because the noun is the direct object of the verb wybieram, so it has to be in the accusative case.

The dictionary form is:

• torba = bag

But in the accusative singular it becomes:

• torbę

This is a very common pattern for feminine nouns ending in -a:

• -a → -ę

Because adjectives in Polish must agree with the noun they describe in:

• gender
• number
• case

Here, torbę is:

• feminine
• singular
• accusative

So the adjective must match:

• fioletową

Compare:

• fioletowa torba = nominative
• fioletową torbę = accusative

Yes, very common.

For many feminine singular noun phrases, you get this change:

• noun: -a → -ę
• adjective: -a → -ą

So:

• fioletowa torba becomes
• fioletową torbę

This is one of the most useful patterns for beginners to recognize.

They are:

• wybierać = to choose, to select
• fioletowy = purple, violet
• torba = bag

These are the forms you would normally look up in a dictionary.

Because Polish does not use articles like English does.

So torbę can mean:

• a bag
• the bag

The exact meaning depends on context.

Yes. Polish word order is more flexible than English because endings show grammatical roles.

The neutral version is:

• Wybieram fioletową torbę.

But you could also say:

• Fioletową torbę wybieram.

That version sounds more marked and gives extra emphasis to fioletową torbę.

Not necessarily. Wybieram comes from the imperfective verb wybierać, so it usually describes an action as ongoing, repeated, or in progress.

So it can mean:

• I’m choosing
• I choose

If you want to stress a completed choice, Polish often uses the perfective partner wybrać.

The final ę is often pronounced less strongly than learners expect. In everyday speech, torbę is roughly like TOR-beh, with a weak nasal quality or sometimes almost just e at the end.

So you should not overdo the nasal sound. The important thing is to recognize that it is still spelled ę because of the grammar.
