Μην χύνεις νερό στο πάτωμα, γιατί γλιστράει.

Μην is the word used to make a negative command in Modern Greek.

So:

• Μην χύνεις... = Don’t spill...

Greek normally does not form negative commands the way English does with don’t + imperative. Instead, it uses μην + subjunctive form of the verb.

That is very normal in Greek. After μην, Greek uses a subjunctive form that often looks exactly like the present tense.

Here, χύνεις is the 2nd person singular form, so it is addressed to one person in an informal way.

This pattern is common:

• γράφεις = you write / are writing
• μην γράφεις = don’t write / don’t keep writing

So even though χύνεις looks like you spill / you are spilling, with Μην it becomes don’t spill.

This is a very important Greek distinction.

• Μην χύνεις uses the imperfective form. It often suggests a general, repeated, or ongoing action. It can feel like Don’t go spilling water or Don’t spill water in general.

• Μην χύσεις uses the aorist form. It often refers to one single act: Don’t spill the water / Be careful not to spill it.

So in your sentence, Μην χύνεις νερό στο πάτωμα sounds like a general warning or instruction.

Χύνω means to spill, to pour out, or to let something flow out.

In this sentence, the best natural translation is spill:

• Μην χύνεις νερό στο πάτωμα = Don’t spill water on the floor

It can sometimes mean simple pouring, but in this context it clearly has the idea of making a mess or creating a hazard.

Because νερό is being used as a mass noun in a general sense.

Greek often leaves out the article with substances or materials when speaking generally:

• Μην χύνεις νερό = Don’t spill water
• Μην πίνεις νερό = Don’t drink water

If you wanted to refer to specific water, you could use the article:

• Μην χύνεις το νερό = Don’t spill the water

So the lack of an article here makes it more general.

στο is a contraction of:

• σε + το = στο

So:

• σε = a preposition that can mean in, on, at, or to, depending on context
• το πάτωμα = the floor

Together:

• στο πάτωμα = on the floor

Greek uses σε much more broadly than English uses any one preposition, so the natural English translation here is on the floor, even though Greek uses σε.

It actually is in the correct case: accusative.

After σε, Greek normally uses the accusative. But πάτωμα is a neuter noun, and many neuter nouns have the same form in the nominative and accusative.

So:

• το πάτωμα = nominative or accusative singular
• after σε: στο πάτωμα

That is completely regular.

It can mean both, depending on the sentence.

Here it means because:

• Μην χύνεις νερό στο πάτωμα, γιατί γλιστράει. = Don’t spill water on the floor, because it’s slippery.

But in a question, γιατί means why:

• Γιατί γλιστράει; = Why is it slippery? / Why does it slip?

So learners have to use the sentence structure and punctuation to tell which meaning it has.

Γλιστράει comes from γλιστράω / γλιστρώ, meaning to slip.

Literally, γλιστράει means it slips. But in this sentence, English usually translates it more naturally as:

• it’s slippery
• or someone can slip

So the Greek wording is a little more verbal than the most natural English version.

A very close Greek alternative with an adjective would be:

• Το πάτωμα είναι γλιστερό = The floor is slippery

But γλιστράει is very natural in everyday Greek.

Greek often leaves the subject unstated when it is obvious from context.

Here, the implied idea is something like:

• the floor slips / is slippery
• or more naturally in English, the floor is slippery
• or even you can slip

So the sentence does not need to say it explicitly. Context tells you that spilled water makes the floor dangerous.

This is very common in Greek: the verb is often enough, and the listener fills in the subject.

Because Greek usually does not need subject pronouns when the verb ending already shows who the subject is.

In χύνεις, the ending -εις already tells you it means you singular.

So Greek says:

• Μην χύνεις...

where English needs:

• Don’t you spill... or more naturally Don’t spill...

The pronoun εσύ could be added for emphasis, but it is not necessary:

• Εσύ μην χύνεις νερό...

That would sound more emphatic, like You, don’t spill water...

Because γιατί γλιστράει is a reason clause: it explains why the speaker is giving the command.

Greek commonly separates that kind of clause with a comma:

• Μην χύνεις νερό στο πάτωμα, γιατί γλιστράει.

So the comma is normal Greek punctuation here.

You would change χύνεις to χύνετε:

• Μην χύνετε νερό στο πάτωμα, γιατί γλιστράει.

χύνετε is used for:

• you all
• or you in a formal/polite singular sense

So this version could mean:

• Don’t spill water on the floor, everyone
• or Please don’t spill water on the floor to one person politely
