Μην αγγίζεις το τηγάνι, είναι πολύ ζεστό.

Μην is used to make a negative command or prohibition in Greek.
So Μην αγγίζεις means Don’t touch.

It is one of the most common ways to tell someone not to do something:

• Μην μιλάς. = Don’t talk.
• Μην τρέχεις. = Don’t run.

Both μη and μην exist, but μην is the normal form before a word beginning with a vowel or in many everyday command structures.

Since αγγίζεις starts with α-, Greek normally uses:

• μην αγγίζεις

So for a learner, the safest choice here is simply to remember the whole pattern:

• μην + verb for negative commands

That is a very common question. In Greek, negative commands are not formed with the regular imperative. Instead, Greek uses:

• μην + subjunctive form

So:

• Μην αγγίζεις = Don’t touch

Even though αγγίζεις looks identical to the present you touch / you are touching, here it is functioning as part of a prohibition after μην.

Also, notice that να is not used here. In many Greek subjunctive constructions you get να, but after μην in a negative command, να is omitted.

Αγγίζεις is second person singular, so it is used when speaking to one person in an informal way.

So this sentence is addressed to one person:

• Μην αγγίζεις το τηγάνι. = Don’t touch the pan.

If you were speaking to:

• more than one person, or
• one person formally

you would say:

• Μην αγγίζετε το τηγάνι.

This is a Greek aspect difference.

• Μην αγγίζεις = Don’t touch / don’t be touching
  This sounds more like a general prohibition or an ongoing/repeated action.

• Μην αγγίξεις = Don’t touch (it even once)
  This is more like a single, complete action.

In real life, both can be translated as Don’t touch, but Greek makes a distinction that English usually does not.

In this sentence, Μην αγγίζεις το τηγάνι sounds very natural for warning someone not to put their hand on it.

Το is the definite article, meaning the.

So:

• το τηγάνι = the pan

Greek uses articles very regularly, often more regularly than English. Since we are talking about a specific pan, the article is needed.

Also, το τηγάνι is the direct object of αγγίζεις:

• touch what? → the pan

Τηγάνι is a neuter noun in Greek.

That means words connected to it must agree with it in gender and number:

• το τηγάνι = neuter singular
• ζεστό = neuter singular adjective

So:

• είναι πολύ ζεστό = it is very hot

The adjective ζεστό matches the thing being described, namely το τηγάνι.

Compare:

• ο καφές είναι ζεστός = the coffee is hot (masculine)
• η σούπα είναι ζεστή = the soup is hot (feminine)
• το τηγάνι είναι ζεστό = the pan is hot (neuter)

Because Greek often drops subject pronouns when they are understood from the context.

In English, you need:

• it is very hot

In Greek, once το τηγάνι has already been mentioned, you can simply say:

• είναι πολύ ζεστό

The subject is understood as it, referring to the pan.

You could say:

• αυτό είναι πολύ ζεστό but in this context that would usually be less natural than simply leaving the pronoun out.

Πολύ means very in this sentence.

So:

• ζεστό = hot
• πολύ ζεστό = very hot

Here πολύ is an adverb, modifying the adjective ζεστό.

A useful thing to remember is that πολύ does not change form here:

• πολύ ζεστό
• πολύ κρύο
• πολύ καλό

A rough pronunciation for an English speaker is:

• Min ang-GHEE-zees to tee-GHA-nee

A few helpful notes:

• αγγίζεις has the stress on -γγί-
• τηγάνι has the stress on -γά-
• Greek γ is not exactly like English g; it is often a softer sound
• the γγ in αγγίζεις is a special combination and may sound a bit like ng + g/y

You do not need a perfect accent immediately, but getting the stress in the right place is especially important:

• αγγίζεις
• τηγάνι
