Έχω μηδέν ευρώ.

• Έχω = I have
• μηδέν = zero
• ευρώ = euros / euro

So the sentence is literally I have zero euros.

Έχω is the 1st person singular present tense of the verb έχω, meaning to have.

So:

• έχω = I have
• έχεις = you have
• έχει = he/she/it has

In this sentence, έχω already tells you the subject is I, so Greek does not need a separate word for I.

Greek often drops subject pronouns when they are not needed, because the verb ending already shows who is doing the action.

So:

• Έχω μηδέν ευρώ = I have zero euros
• Εγώ έχω μηδέν ευρώ also means I have zero euros, but εγώ adds emphasis, like I have zero euros.

Using no pronoun is the normal, natural choice.

They are completely different words:

• μηδέν = zero
• δεν = not

So:

• Έχω μηδέν ευρώ = I have zero euros
• Δεν έχω ευρώ = I do not have euros / I have no euros

Both can express a similar idea, but the nuance is different:

• μηδέν gives an exact number
• δεν simply makes the sentence negative

The noun ευρώ is special: its form usually stays the same in the singular and plural in everyday use.

So you say:

• ένα ευρώ = one euro
• δύο ευρώ = two euros
• μηδέν ευρώ = zero euros

Unlike many Greek nouns, it does not change to a separate plural form here.

After numbers and quantity words, Greek normally does not use the article.

So:

• μηδέν ευρώ = zero euros
• πέντε ευρώ = five euros
• δέκα ευρώ = ten euros

Adding an article here would sound unnatural.

Yes. That is very natural Greek.

The difference is mainly one of nuance:

• Έχω μηδέν ευρώ = I have zero euros
  This sounds more exact, countable, or emphatic.
• Δεν έχω ευρώ = I don’t have any euros
  This is a more general and very common way to say it.

So both are correct, but Έχω μηδέν ευρώ highlights the number zero.

Yes, it is grammatical and understandable. It sounds natural when you want to stress the exact amount: zero.

But in everyday conversation, Greeks might often prefer:

• Δεν έχω ευρώ
• Δεν έχω καθόλου ευρώ = I have no euros at all
• Δεν έχω ούτε ένα ευρώ = I don’t even have one euro

So Έχω μηδέν ευρώ is fine, especially when talking about an exact amount, but it is not always the most conversational phrasing.

A simple pronunciation guide is:

EH-ho mee-THEN ev-RO

More closely:

• Έχω = EH-ho
• μηδέν = mee-THEN
  The δ sounds like th in this
• ευρώ = ev-RO

The stress falls on:

• Έχω
• μηδέν
• ευρώ

Greek uses accent marks to show which syllable is stressed.

So:

• Έχω is stressed on the first syllable
• μηδέν is stressed on the second
• ευρώ is stressed on the second

The accent is important for correct pronunciation and is normally written in standard Greek spelling.

Yes, Greek word order is more flexible than English, but the neutral order here is:

Έχω μηδέν ευρώ.

If you change the order, you usually change the emphasis. For example:

• Μηδέν ευρώ έχω. = Zero euros is what I have.

That sounds more emphatic or contrastive. For a learner, the basic order Έχω μηδέν ευρώ is the safest and most natural one to use.
