Δεν ξέρω πού να βάλω αυτή την ταμπέλα, γιατί ο τοίχος δίπλα στην πόρτα είναι ήδη γεμάτος.

In Greek, δεν is the normal negation used with indicative verbs, and it goes before the verb:

• ξέρω = I know
• δεν ξέρω = I don’t know

So the order is very straightforward: negative particle + verb.

Here πού means where in an indirect question: I don’t know where...

The accent helps distinguish it from που, which often works as that / which / who in relative clauses.

Compare:

• Δεν ξέρω πού είναι. = I don’t know where it is.
• Το βιβλίο που θέλω... = The book that I want...

So in this sentence, πού is the interrogative adverb where.

να is a very common Greek particle that introduces the subjunctive. English often translates this structure with to or with a finite clause, depending on the sentence.

Here:

• πού να βάλω literally means something like where I should put / where to put

After verbs like ξέρω (know), Greek often uses this pattern:

• Δεν ξέρω τι να κάνω. = I don’t know what to do.
• Δεν ξέρω πού να πάω. = I don’t know where to go.
• Δεν ξέρω πού να βάλω... = I don’t know where to put...

So να is not exactly the same as English to, but in this kind of sentence that is often the most natural translation.

Because after να, Greek normally uses the subjunctive, and here the verb appears in its aorist subjunctive form:

• βάζω = present stem, more like I put / I am putting / I put regularly
• να βάλω = aorist subjunctive, usually for one complete action: to put / to place

In this sentence, the speaker is thinking about one act of placing the sign somewhere, so να βάλω is the natural choice.

Compare:

• Πού να βάλω την ταμπέλα; = Where should I put the sign?
• Βάζω τα βιβλία εδώ κάθε μέρα. = I put the books here every day.

So βάλω fits because this is a single completed placement, not a repeated or ongoing action.

Because the phrase is the direct object of βάλω.

The dictionary form is:

• αυτή η ταμπέλα = this sign as the subject

But after put, the noun is an object, so Greek uses the accusative:

• αυτή την ταμπέλα = this sign as the object

So the forms change:

• nominative: αυτή η ταμπέλα
• accusative: αυτή την ταμπέλα

This is a very common pattern in Greek: articles, demonstratives, and adjectives change form depending on case.

Both τη and την exist, but the final -ν is often kept before vowels and certain consonants. Since ταμπέλα begins with τ, keeping the -ν is standard and very natural:

• την ταμπέλα

You will often see and hear this kind of pattern:

• την πόρτα
• τον τοίχο
• έναν φίλο

For learners, it is safest to accept την ταμπέλα here as the normal standard form.

ταμπέλα usually means sign, signboard, placard, or sometimes label, depending on context.

In this sentence, because it is something being placed on a wall, sign is the most natural meaning.

So it suggests some physical sign, notice, or board that needs to be put somewhere.

Greek γιατί can mean both why? and because, just like a few English words can have different functions depending on context.

Here it introduces a reason, so it means because:

• ...γιατί ο τοίχος... είναι ήδη γεμάτος.
• ...because the wall... is already full.

If it were a question, it could mean why:

• Γιατί έφυγες; = Why did you leave?

So the role in the sentence tells you the meaning.

δίπλα means next to / beside.

It is often followed by a phrase with σε plus the article:

• δίπλα σε την πόρτα → contracted to δίπλα στην πόρτα

So:

• δίπλα στην πόρτα = next to the door

This contraction is very common:

• σε + την = στην
• σε + το = στο

So you should learn στην πόρτα as the normal contracted form.

The full form is:

• σε την πόρτα = at/on/to the door

But in normal Greek, this contracts to:

• στην πόρτα

This is the standard written and spoken form.

You may sometimes hear στη in speech in some contexts, but στην is the safe standard form here, especially before a word beginning with π.

Because Greek articles change for gender, number, and case.

Here:

• ο τοίχος is masculine singular nominative because it is the subject of είναι
• την πόρτα is feminine singular accusative after σε / στην

So the articles are different because the nouns have different grammatical roles and different genders.

A quick breakdown:

• ο τοίχος = the wall (subject)
• την πόρτα = the door (object of the preposition-like phrase)

This kind of article change is one of the most important things to get used to in Greek.

Because it agrees with ο τοίχος, which is masculine singular.

• ο τοίχος = masculine singular
• γεμάτος = masculine singular adjective

Compare:

• ο τοίχος είναι γεμάτος = the wall is full
• η πόρτα είναι γεμάτη = the door is full
• το δωμάτιο είναι γεμάτο = the room is full

Greek adjectives must agree with the noun they describe.

Because Greek, like English, can leave that understood from context.

• είναι ήδη γεμάτος = it is already full

If you want to say what it is full of, you can add it:

• είναι γεμάτος με αφίσες = it is full of posters
• είναι γεμάτος με ταμπέλες = it is full of signs

But in this sentence, the speaker only needs the general idea: there is no more space.

ήδη means already.

Here:

• είναι ήδη γεμάτος = is already full

Its placement is very natural in Greek. It often appears before the adjective or participle it modifies:

• είναι ήδη έτοιμος = he is already ready
• έχω ήδη φύγει = I have already left

So in this sentence, ήδη emphasizes that the wall is full already, which explains why the speaker does not know where to put the sign.

Yes, Greek word order is more flexible than English, although not completely free.

The sentence as written is very natural:

• Δεν ξέρω πού να βάλω αυτή την ταμπέλα, γιατί ο τοίχος δίπλα στην πόρτα είναι ήδη γεμάτος.

But Greek can move things around for emphasis. For example, you might hear:

• Δεν ξέρω πού να βάλω την ταμπέλα αυτή...
• Γιατί ο τοίχος δίπλα στην πόρτα είναι ήδη γεμάτος, δεν ξέρω πού να βάλω αυτή την ταμπέλα.

These are possible, but the original version is the most neutral and natural for a learner to model.

Usually yes in this sentence, but like English put, it has a broad range of uses.

βάζω / βάλω can mean:

• put
• place
• set
• sometimes insert or add, depending on context

So here πού να βάλω αυτή την ταμπέλα is very naturally where to put this sign, but place this sign would also match the Greek well.

Because γιατί introduces a subordinate clause giving the reason:

• main clause: Δεν ξέρω πού να βάλω αυτή την ταμπέλα
• reason clause: γιατί ο τοίχος δίπλα στην πόρτα είναι ήδη γεμάτος

Greek punctuation here works much like English punctuation with because. The comma helps separate the explanation from the main statement.
