Δεν έχω κανένα πρόβλημα τώρα.

This is a very common question for English speakers.

In Greek, double negation is normal.
So δεν and κανένα work together, not against each other.

• δεν = the basic negation marker, not
• κανένα = no / any in negative contexts

So:

• Δεν έχω κανένα πρόβλημα = I have no problem / I don’t have any problem

In English, two negatives often cancel each other in standard grammar, but in Greek they usually reinforce the negative meaning.

Δεν is the standard way to negate a verb in Greek. It usually means not.

It normally comes right before the verb:

• έχω = I have
• δεν έχω = I do not have / I don’t have

So in this sentence:

• Δεν έχω = I don’t have

This is very typical Greek word order for negation.

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

So:

• έχω = I have

Other useful forms are:

• έχεις = you have
• έχει = he/she/it has
• έχουμε = we have
• έχετε = you have
• έχουν = they have

In the sentence Δεν έχω κανένα πρόβλημα τώρα, έχω simply means I have.

Here κανένα means no or any, depending on how you translate the whole sentence into English.

So:

• κανένα πρόβλημα = no problem / any problem

Because the sentence is negative with δεν, English often translates it as:

• I don’t have any problem now or more naturally
• I have no problem now or
• I don’t have any problems now

Greek often uses κανένας / καμία / κανένα in negative sentences to express not any / no.

Because πρόβλημα is a neuter noun.

The forms agree with the gender of the noun:

• κανένας for masculine nouns
• καμία for feminine nouns
• κανένα for neuter nouns

Since:

• το πρόβλημα = the problem

it is neuter, so Greek uses:

• κανένα πρόβλημα

This is gender agreement, which is very important in Greek.

Because πρόβλημα is in the accusative singular, and for this noun the accusative singular looks the same as the nominative singular.

In the sentence, πρόβλημα is the direct object of έχω:

• έχω πρόβλημα = I have a problem

Greek nouns often change form depending on case, but many neuter nouns have the same form in nominative and accusative singular.

So:

• ένα πρόβλημα
• κανένα πρόβλημα
• το πρόβλημα

all keep πρόβλημα in this context.

Yes, very often it can.

Greek frequently uses the singular in places where English might prefer the plural. So:

• Δεν έχω κανένα πρόβλημα can mean
  I have no problem
  or more naturally in many contexts
  I don’t have any problems

The exact English translation depends on context.

If someone asks whether everything is okay, this sentence can naturally mean No, I have no problems right now.

Τώρα means now.

It tells you the time frame:

• Δεν έχω κανένα πρόβλημα τώρα = I don’t have any problem now

It can suggest:

• at this moment
• for now
• currently

So maybe there was a problem before, or there may be one later, but right now there isn’t one.

Yes, Greek word order is fairly flexible.

The sentence:

• Δεν έχω κανένα πρόβλημα τώρα

is completely natural.

But you could also hear:

• Τώρα δεν έχω κανένα πρόβλημα
• Δεν έχω τώρα κανένα πρόβλημα

The position changes the emphasis a little:

• Τώρα δεν έχω... emphasizes now
• Δεν έχω κανένα πρόβλημα τώρα sounds very natural and neutral

So the end position is common, but not the only possibility.

Not exactly.

Compare:

• Έχω ένα πρόβλημα = I have a problem
• Δεν έχω ένα πρόβλημα = literally I don’t have one problem

That second one sounds marked and can imply contrast, like:

• I don’t have one problem, I have several or
• It’s not one specific problem

But:

• Δεν έχω κανένα πρόβλημα = I don’t have any problem / I have no problem

This is the normal way to express the idea.

So κανένα is important here.

Yes, κανένα πρόβλημα by itself can mean no problem in conversation, similar to English.

For example, if someone thanks you or asks for a small favor, you might hear:

• Κανένα πρόβλημα! = No problem!

But in your sentence, it is part of a full statement:

• Δεν έχω κανένα πρόβλημα τώρα = I don’t have any problem now

So the same words can appear in different situations, but the structure here is clearly a full sentence with a verb.

Κανένα is pronounced roughly ka-ne-NA.

The stress is on the last syllable:

• κα-νε-νά

That accent mark is important in Greek because it tells you where the stress goes.

Similarly:

• πρόβλημα = PRO-vli-ma
• τώρα = TO-ra
• έχω = E-ho

Getting the stress right will make your Greek sound much more natural.

It is neutral and standard. You can use it in both everyday speech and normal writing.

It does not sound especially formal or especially casual. It is just a straightforward Greek sentence.

That makes it a very useful pattern to learn:

• Δεν έχω κανένα + noun
• I don’t have any + noun

For example:

• Δεν έχω κανένα χρόνο. = I don’t have any time.
• Δεν έχω καμία ιδέα. = I have no idea.
• Δεν έχω κανέναν λόγο. = I have no reason.

A useful breakdown is:

• Δεν = not
• έχω = I have
• κανένα = no / any
• πρόβλημα = problem
• τώρα = now

So the structure is:

negation + verb + negative determiner + noun + time expression

That gives:

• Δεν έχω κανένα πρόβλημα τώρα.

This is a very common Greek pattern, and once you learn it, you can build many similar sentences.
