Codziennie skręcam w lewo przy banku i idę prosto do pracy.

Because Polish word order is fairly flexible. Putting codziennie first emphasizes the idea of every day and sets the scene right away.

You could also say:

• Skręcam codziennie w lewo przy banku i idę prosto do pracy.

That is still correct, but it sounds a little different in emphasis. In Polish, changing word order often changes focus, not basic meaning.

Skręcam is the present tense of an imperfective verb, and here it describes a habitual action: something the speaker does regularly.

Since the sentence begins with codziennie, Polish naturally uses the present tense to express a repeated everyday action:

• codziennie skręcam = I turn every day

By contrast, skręcę is usually future perfective and would mean something more like I will turn / I’ll make the turn once.

W lewo is a fixed and very common Polish expression meaning to the left or left in movement contexts.

Similarly:

• w prawo = to the right
• prosto = straight ahead

Here, w is used with the accusative to show direction. So:

• lewo is the accusative form of lewa / lewo used in this expression

For a learner, the easiest approach is to memorize skręcić / skręcać w lewo and w prawo as set phrases.

After przy, Polish uses the locative case.

So:

• bank = basic dictionary form
• przy banku = near/by the bank

Other examples:

• przy domu = by the house
• przy ulicy = by the street
• przy szkole = by the school

So banku is the locative singular form of bank.

Not exactly. Przy banku usually means by the bank, near the bank, or next to the bank.

In this sentence, it helps describe location on a route: the speaker turns left when they get to the area by the bank.

English at the bank can mean inside the bank / at that place as a destination, but Polish przy banku is more clearly about being beside it or near it.

This is a very common question for English speakers.

Both verbs can relate to going, but they are used differently:

• iść / idę = going in one direction, one trip, movement step by step
• chodzić / chodzę = going around, going habitually in a general sense, repeated trips

So why idę here, even though the sentence says codziennie?

Because the speaker is describing their route as a sequence of movements:

• I turn left
• and go straight to work

Polish often uses idę in route descriptions like this, even when the whole situation is habitual.

A more general statement like I go to work on foot every day might use chodzę, but a step-by-step route often prefers idę.

Prosto here means straight ahead or simply straight.

So:

• idę prosto = I go straight
• iść prosto = to go straight ahead

It is an adverb, describing how the person goes.

Because do requires the genitive case.

The noun is:

• praca = work

But after do, it changes to:

• do pracy = to work

This is very common in Polish:

• do domu = home / to the house
• do szkoły = to school
• do sklepu = to the shop

So pracy is the genitive singular form of praca.

Because Polish often leaves out subject pronouns when they are already clear from the verb ending.

Here:

• skręcam already means I turn
• idę already means I go

So ja is unnecessary unless you want extra emphasis or contrast.

For example:

• Ja skręcam w lewo, a on w prawo.
  = I turn left, but he turns right.

Without that kind of contrast, Polish usually omits ja.

Because i means and, and in a simple sentence joining two actions with the same subject, Polish normally does not use a comma before it.

So this is correct:

• Codziennie skręcam w lewo przy banku i idę prosto do pracy.

A comma would usually appear only in more complex structures, not in this straightforward X and Y pattern.

Yes, possibly, but the nuance changes slightly.

• przy banku = by / near the bank
• obok banku = next to / beside the bank

Obok can sound a bit more specifically right next to, while przy is often a little broader and very natural in route descriptions.

So both can work, but przy banku is a very normal choice here.

Yes. In Polish, just like in English, the present tense is commonly used for habits and routines.

Because of codziennie, the sentence clearly means a repeated action:

• Codziennie skręcam... i idę...
  = Every day I turn... and go...

So there is no need for a special tense for habitual actions here. The adverb codziennie makes the routine meaning clear.
