Kursor stoi w miejscu, bo mysz jest zepsuta.

In Polish, stać / stoi often means not just to stand upright, but more generally to stay still or to remain in one place.

So Kursor stoi w miejscu is very natural Polish for The cursor is staying in one place / not moving.

A few similar ideas:

• Samochód stoi na ulicy = The car is standing/parked on the street
• Zegar stoi = The clock has stopped
• Kursor stoi w miejscu = The cursor is stuck

So even though English would not normally say the cursor stands, Polish does.

W miejscu means in one place or in the same spot. In this sentence, it suggests that the cursor is not moving.

So:

• stoi w miejscu = stays in the same place
• more naturally in English: is stuck or is not moving

This is a very common expression in Polish, not just for physical objects:

• Samochód stoi w miejscu = The car isn’t moving
• Stoimy w miejscu can even mean We are making no progress

Because Polish uses cases, and the preposition w usually requires a case form.

Here w means in, and because this is a location, miejsce changes into the locative case:

• basic form: miejsce
• after w: w miejscu

So:

• miejsce = place
• w miejscu = in a place / in one place

This is a normal pattern:

• dom → w domu = in the house
• biuro → w biurze = in the office
• miejsce → w miejscu = in the place / in one place

Yes. Bo means because.

In this sentence:

• Kursor stoi w miejscu, bo mysz jest zepsuta.
• The cursor is not moving because the mouse is broken.

Bo is very common and natural in everyday Polish. It is slightly more conversational than words like ponieważ or gdyż, but it is completely standard.

Compare:

• bo = because very common in speech
• ponieważ = because / since a bit more formal
• gdyż = because / for more formal or written

Not all feminine nouns in Polish end in -a. Mysz is one of the feminine nouns that ends in a consonant-like sound.

So:

• mysz = feminine noun
• that is why the adjective must also be feminine: zepsuta

This matters for agreement:

• ten kursor = masculine
• ta mysz = feminine

Even though mysz means both mouse the animal and computer mouse, its grammatical gender stays feminine.

Because adjectives in Polish must agree with the noun in gender, number, and case.

Here the noun is mysz, which is feminine, so the adjective must also be feminine:

• masculine: zepsuty
• feminine: zepsuta
• neuter: zepsute

Examples:

• telefon jest zepsuty = the phone is broken
• mysz jest zepsuta = the mouse is broken
• urządzenie jest zepsute = the device is broken

So zepsuta is used only because mysz is feminine.

In standard Polish, you normally keep jest in this kind of present-tense sentence.

So:

• mysz jest zepsuta = the mouse is broken

Unlike some other Slavic languages, Polish usually does not drop the present-tense form of to be in ordinary sentences like this.

Without jest, mysz zepsuta would sound incomplete, very colloquial, or like a note/headline rather than a normal sentence.

So for learners, the safe rule is:

• use jest in the present tense with this type of predicate adjective

They are related, but not identical.

• mysz jest zepsuta = the mouse is broken
  • focuses on the current state
• mysz się zepsuła = the mouse broke / has broken
  • focuses on the event that happened

So in context:

• Kursor stoi w miejscu, bo mysz jest zepsuta.
  • The cursor is not moving because the mouse is broken.

You could also say:

• Kursor stoi w miejscu, bo mysz się zepsuła.
  • The cursor is not moving because the mouse broke.

Both are natural, but the first describes a condition, while the second describes what happened.

Yes. Polish word order is more flexible than English word order, because cases help show grammatical roles.

The neutral order here is:

• Kursor stoi w miejscu, bo mysz jest zepsuta.

But other orders are possible for emphasis, for example:

• Bo mysz jest zepsuta, kursor stoi w miejscu.
• Kursor stoi w miejscu, bo zepsuta jest mysz.

These alternatives are understandable, but the original version is the most natural and neutral for everyday use.

Because Polish does not have articles like English a/an and the.

So:

• kursor can mean a cursor or the cursor
• mysz can mean a mouse or the mouse

The exact meaning depends on context.

In this sentence, English naturally uses the:

• The cursor is staying in one place because the mouse is broken.

But Polish simply says:

• Kursor stoi w miejscu, bo mysz jest zepsuta.

A rough English-style pronunciation would be:

KOOR-sor STOY v myes-tsu, bo mish yest zep-SOO-ta

A few helpful sound notes:

• kur in kursor is like koor
• stoi sounds roughly like stoy
• w is pronounced like English v
• sz in mysz sounds like English sh
• j in jest sounds like English y
• z in zepsuta is like English z

Not every sound matches English exactly, but that approximation is a good start.
