Pies nie lubi burzy, bo każdy grzmot go stresuje.

Pies is the subject of the sentence, so it is in the nominative case.

• pies = dog (nominative singular)
• psa = dog in forms like accusative/genitive singular

In this sentence, the dog is the one doing the not liking, so Polish uses pies.

This is a very common Polish question, and the reason is negation.

Normally, lubić takes the accusative:

• Lubi burzę = He/She likes the storm

But when the verb is negated, Polish often changes the object to the genitive:

• Nie lubi burzy = He/She doesn’t like the storm

So:

• burza = nominative
• burzę = accusative
• burzy = genitive

Because of nie lubi, we get burzy.

Usually burza means thunderstorm, not just any storm in general.

So this sentence suggests the dog is afraid of a storm with thunder, which fits the second part:

• każdy grzmot go stresuje = every thunderclap stresses him out

If you want a more general word for storm, context matters, but burza very often implies thunder and lightning.

Każdy means every or each, and it must agree with the noun it describes.

• grzmot is a masculine singular noun
• so we use każdy

That is why it is:

• każdy grzmot = every thunderclap / each clap of thunder

Not:

• każda grzmot — wrong, because grzmot is not feminine
• każde grzmot — wrong, because grzmot is not neuter

Grzmot means a clap of thunder, thunderclap, or sometimes simply thunder, depending on context.

In this sentence, każdy grzmot is most naturally understood as:

• every thunderclap

So the idea is that each loud thunder sound makes the dog stressed.

Go means him.

It refers back to pies:

• Pies nie lubi burzy, bo każdy grzmot go stresuje.
• The dog doesn’t like thunderstorms because every thunderclap stresses him out.

Here, go is the direct object of stresuje:

• stresować kogoś = to stress someone out

So:

• grzmot stresuje go
• more natural Polish word order: grzmot go stresuje

Polish word order is flexible, but short pronouns like go, mu, cię, mi often appear early in the clause.

So:

• każdy grzmot go stresuje sounds natural
• każdy grzmot stresuje go is possible, but it usually sounds more marked or emphatic

In everyday Polish, short unstressed pronouns often like to sit near the beginning of the predicate part of the sentence.

Because the sentence means causes stress, not is stressed.

• stresować kogoś = to stress someone out
• być zestresowanym = to be stressed

So:

• Każdy grzmot go stresuje = every thunderclap stresses him out
• On jest zestresowany = he is stressed

The Polish sentence focuses on the cause of the stress.

Yes. Nie lubi is present tense, and here it expresses a general habit or general attitude.

• lubi = likes
• nie lubi = doesn’t like

So this is not about one single moment only. It means, in general, the dog does not like thunderstorms.

Polish often uses the singular to talk about something in a general sense.

So:

• nie lubi burzy = he doesn’t like a thunderstorm / thunderstorms in general
• każdy grzmot = every thunderclap

This sounds natural in Polish. English sometimes prefers plural forms in similar situations, but Polish often uses singular for general statements.

Bo means because.

It introduces the reason:

• Pies nie lubi burzy = The dog doesn’t like thunderstorms
• bo każdy grzmot go stresuje = because every thunderclap stresses him out

So bo connects the main statement with its explanation.

Yes, you could say:

• Pies nie lubi burzy, ponieważ każdy grzmot go stresuje.

That is grammatically correct.

The difference is mainly style:

• bo = very common, everyday, natural
• ponieważ = more formal, more written, sometimes more careful in tone

In ordinary speech, bo is usually the most natural choice.

Yes, Polish word order is quite flexible, though some versions sound more natural than others.

The neutral version is:

• Pies nie lubi burzy, bo każdy grzmot go stresuje.

You might also hear:

• Pies nie lubi burzy, bo go stresuje każdy grzmot.

That version puts a bit more focus on każdy grzmot.

So yes, the order can change, but the original sentence is a very natural default order.

Because the subject is singular:

• pies = one dog

So the verb must also be singular:

• pies lubi = the dog likes
• pies nie lubi = the dog doesn’t like

If the subject were plural, the verb would change:

• Psy nie lubią burzy = Dogs don’t like thunderstorms

Grammatically, pies is a masculine noun, yes.

That does not always mean the actual dog is male in real life. In Polish, noun gender is a grammatical feature.

However, because the sentence later uses go = him, this particular sentence does sound like it is referring to the dog as male.

If you wanted to talk about a female dog more explicitly, you might use suka instead, though that word has to be used carefully because of its strong meaning in some contexts.

Yes. Lubi is the 3rd person singular present form of lubić.

Full pattern:

• lubię = I like
• lubisz = you like
• lubi = he/she/it likes
• lubimy = we like
• lubicie = you all like
• lubią = they like

So with pies, we use:

• pies lubi
• pies nie lubi

Yes, exactly. The second part makes that clear.

• burza gives the general situation: the thunderstorm
• każdy grzmot go stresuje explains the specific reason: each thunderclap stresses him out

So the sentence implies the dog dislikes thunderstorms because of the thunder sounds.
