Μην τρέχεις στην κουζίνα, γιατί γλιστράει το πάτωμα μετά το σφουγγάρισμα.

Because μην is used for negative commands and negative subjunctive-style forms.

• Μην τρέχεις = Don’t run
• Δεν τρέχεις = You are not running

So:

• δεν negates statements
• μη(ν) negates commands, wishes, and subjunctive-type forms

In this sentence, the speaker is telling someone not to do something, so μην is the correct choice.

Yes, τρέχεις can also be the regular 2nd person singular present form, but after μην it functions as a negative command:

• τρέχεις = you run / you are running
• μην τρέχεις = don’t run

This is very common in Modern Greek. The form looks the same as the present form, but the particle μην changes the function.

Compare:

• Τρέχεις στην κουζίνα. = You are running to/in the kitchen.
• Μην τρέχεις στην κουζίνα. = Don’t run to/in the kitchen.

It is singular — talking to one person.

• Μην τρέχεις = Don’t run (to one person)
• Μην τρέχετε = Don’t run (to more than one person, or formal singular)

So if you were speaking to a child, friend, or one familiar person, Μην τρέχεις is right.

στην is a contraction of:

• σε = to / in / at
• την = the (feminine accusative singular)

So:

• σε την κουζίνα → στην κουζίνα

Since κουζίνα is feminine, την becomes part of the contraction.

Depending on context, στην κουζίνα can mean:

• to the kitchen
• in the kitchen

With a verb of motion like τρέχω, English often prefers to the kitchen, but Greek uses σε + article + noun very naturally here.

Yes. After σε (and therefore after στην), Greek normally uses the accusative.

For η κουζίνα:

• nominative: η κουζίνα
• accusative: την κουζίνα

That is why you see στην κουζίνα and not στη κουζίνα with some other case ending. In this noun, nominative and accusative happen to look very similar except for the article.

Yes. γιατί can mean both:

• why?
• because

In this sentence, it means because:

• Μην τρέχεις στην κουζίνα, γιατί γλιστράει το πάτωμα...
• Don’t run in/to the kitchen, because the floor is slippery/slips...

You can tell the meaning from context and intonation:

• Γιατί τρέχεις; = Why are you running?
• Τρέχω γιατί βιάζομαι. = I’m running because I’m in a hurry.

Yes, literally it is something like the floor slips / is slippery.

In Greek, γλιστράω / γλιστράω-γλιστράει can be used in a way that English often translates more naturally as:

• the floor is slippery
• the floor is slippery after mopping
• the floor slips

So γλιστράει το πάτωμα is a normal Greek way to express that the floor is slippery.

A learner might expect an adjective, but Greek often uses the verb γλιστράει in everyday speech.

Greek word order is more flexible than English word order.

So both of these are possible:

• Γλιστράει το πάτωμα
• Το πάτωμα γλιστράει

Both mean roughly the same thing.

Putting the verb first can sound very natural in Greek, especially in spoken language. English usually prefers subject + verb (the floor is slippery), but Greek does not have to follow that order.

Both are used in Modern Greek.

• γλιστράει
• γλιστρά

They are alternative present-tense forms in everyday language. γλιστράει may sound a bit fuller or more explicit, while γλιστρά is also very common and natural.

So you may hear:

• Το πάτωμα γλιστράει
• Το πάτωμα γλιστρά

Both are correct.

Greek uses the definite article much more often than English.

So το πάτωμα literally means the floor, and in context it refers to the relevant floor — the kitchen floor.

Greek often prefers the article in places where English might still use one, but Greek is generally more article-friendly overall. In this sentence, το πάτωμα sounds completely natural and expected.

It means after the mopping or more naturally after mopping.

Breakdown:

• μετά = after
• το σφουγγάρισμα = the mopping

So the structure is:

• μετά + accusative noun phrase

This is a very common pattern in Modern Greek:

• μετά το φαγητό = after the meal / after eating
• μετά το μάθημα = after the lesson
• μετά το σφουγγάρισμα = after mopping

It is a noun.

It comes from the verb:

• σφουγγαρίζω = to mop

And the noun:

• το σφουγγάρισμα = the mopping / the act of mopping

This kind of noun is very common in Greek: a verb can produce a noun referring to the action itself.

Examples:

• διαβάζω = I read / study

• το διάβασμα = reading / studying

• σφουγγαρίζω = I mop
• το σφουγγάρισμα = mopping

In Modern Greek, μετά can be used directly with an article and noun:

• μετά το σφουγγάρισμα

This is the normal and natural way to say after mopping.

You may also see μετά από... in some contexts, but here μετά το σφουγγάρισμα is the straightforward standard expression.

Yes, it can.

Greek σε + accusative often covers meanings that English separates into:

• to
• in
• at

So στην κουζίνα can mean:

• to the kitchen
• in the kitchen

The verb and context tell you which English translation fits best.

Here, because the warning is about running and the slippery floor in the kitchen, English could naturally say either:

• Don’t run into the kitchen...
• Don’t run in the kitchen...

Both match the Greek idea well.

Yes, very natural.

It sounds like something a parent, teacher, or another adult might say to a child or to someone moving carelessly around the house:

• Μην τρέχεις στην κουζίνα, γιατί γλιστράει το πάτωμα μετά το σφουγγάρισμα.

It is idiomatic, everyday Greek, and all the key parts are common:

• Μην + verb for a negative command
• στην κουζίνα for location/direction
• γιατί for because
• γλιστράει το πάτωμα for the floor is slippery
• μετά το σφουγγάρισμα for after mopping
