Δεν έχω ακόμα επαφή με όλους τους γείτονες στο καινούριο κτίριο.

Because Greek usually drops subject pronouns when they are not needed.

The verb έχω already tells you the subject is I:

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

So Δεν έχω... naturally means I don’t have... without needing εγώ.

You could add εγώ for emphasis:

• Εγώ δεν έχω ακόμα επαφή... = I don’t yet have contact...

But in a normal neutral sentence, Greek usually leaves it out.

Δεν is the basic particle used to make a verb negative in Greek.

So:

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

It normally goes right before the verb.

In this sentence, ακόμα is best understood as yet or still, depending on how you phrase it in English.

• Δεν έχω ακόμα επαφή... = I don’t have contact yet...
• or I still don’t have contact...

Both ideas are close, but in English yet often sounds most natural in this kind of sentence.

So ακόμα here signals that the situation has not changed up to now.

Greek adverbs often have flexible placement, but some positions sound more natural than others.

Here:

• Δεν έχω ακόμα επαφή...

This is a very natural word order and means:

• I don’t yet have contact...

You may also hear:

• Ακόμα δεν έχω επαφή...

That version puts more focus on not yet.

So both are possible, but they can differ a little in rhythm or emphasis.

Επαφή literally means contact.

In this sentence, έχω επαφή με... means something like:

• I’m in contact with...
• I have had contact with...
• I know / interact with...

So it does not necessarily mean physical contact. It refers to social contact, acquaintance, or communication.

In context, Δεν έχω ακόμα επαφή με όλους τους γείτονες suggests:

• I haven’t gotten to know all the neighbors yet.
• I’m not yet in touch with all the neighbors.

Greek often leaves out the article in expressions where English might also use a bare noun, especially in combinations like:

• έχω επαφή = have contact
• έχω χρόνο = have time
• έχω δουλειά = have work

So έχω επαφή is a natural phrase meaning to have contact.

If you added an article, the meaning could become more specific:

• έχω την επαφή would sound like I have the contact or the connection, which is a different idea.

Because after με (with), Greek uses the accusative case.

So:

• όλοι = nominative plural, used for subjects
• όλους = accusative plural, used here after με

Also, Greek normally uses the article in this structure:

• όλους τους γείτονες = all the neighbors

So the phrase breaks down like this:

• με = with
• όλους = all
• τους γείτονες = the neighbors

Because όλους must agree with the noun it describes.

Here the noun is:

• γείτονες = neighbors

And because it comes after με, it must be in the accusative plural:

• τους γείτονες

So the word όλους also becomes accusative plural masculine:

• όλους

This kind of agreement is very important in Greek:

• gender
• number
• case

all have to match.

That is just how Greek normally expresses all the...

Greek often uses:

• όλος + article + noun

For example:

• όλη η μέρα = the whole day
• όλο το σπίτι = the whole house
• όλους τους γείτονες = all the neighbors

So the article is not extra or optional here in standard Greek. It is part of the normal structure.

Here γείτονες is accusative plural masculine.

The basic singular form is:

• ο γείτονας = the neighbor

Forms:

• ο γείτονας = nominative singular
• τον γείτονα = accusative singular
• οι γείτονες = nominative plural
• τους γείτονες = accusative plural

In this sentence, it appears as τους γείτονες because it follows με.

Στο is a contraction of:

• σε + το = στο

Here:

• σε = in / at / to
• το = the

So:

• στο καινούριο κτίριο = in the new building

This contraction is extremely common:

• στο = σε το
• στη = σε τη(ν)
• στον = σε τον
• στους = σε τους

Modern Greek often uses σε for several ideas that English separates into different prepositions such as:

• in
• at
• to
• sometimes on

So στο καινούριο κτίριο can mean:

• in the new building
• at the new building

depending on context.

This is very normal in Greek. You should not expect a one-to-one match with English prepositions.

Κτίριο is a neuter singular noun, so the adjective must match it.

• το κτίριο = the building
• το καινούριο κτίριο = the new building

So καινούριο is the neuter singular accusative/nominative form of καινούριος.

Basic forms:

• καινούριος = masculine
• καινούρια / καινούργια = feminine
• καινούριο / καινούργιο = neuter

Yes, νέο κτίριο is possible.

Both καινούριο and νέο can mean new, but there can be a nuance:

• καινούριο often emphasizes brand-new or recently acquired/made
• νέο can mean new in a broader sense, including recent, modern, or different from before

In many everyday sentences, they overlap a lot.

So:

• στο καινούριο κτίριο = in the new/newly-built or brand-new building
• στο νέο κτίριο = in the new building

Both are natural, though καινούριο often sounds a bit more colloquial.

Both κτίριο and κτήριο are used.

• κτίριο is very common in Modern Greek
• κτήριο also exists and is accepted

In everyday use, many speakers treat them as variants of the same word.

So if you see either:

• το κτίριο
• το κτήριο

they both mean the building.

Yes, absolutely.

Although the wording is literally about having contact, in real-life context it can naturally imply:

• I haven’t met all the neighbors yet.
• I don’t know all the neighbors yet.
• I haven’t gotten acquainted with all the neighbors yet.

Greek often uses broader expressions like έχω επαφή με... where English might choose a more specific verb depending on context.

It could be, but it changes the nuance a bit.

Compare:

• Δεν έχω ακόμα επαφή με όλους τους γείτονες.

  • I’m not yet in contact with / acquainted with all the neighbors.
  • Slightly broader, about interaction or contact.

• Δεν γνωρίζω ακόμα όλους τους γείτονες.

  • I don’t know all the neighbors yet.
  • More directly about knowing or having met them.

So the original sentence is natural if the focus is on contact/connection, while γνωρίζω is more direct if the focus is specifically knowing who they are.

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

The neutral version is:

• Δεν έχω ακόμα επαφή με όλους τους γείτονες στο καινούριο κτίριο.

But you could also hear:

• Ακόμα δεν έχω επαφή με όλους τους γείτονες στο καινούριο κτίριο.
• Με όλους τους γείτονες στο καινούριο κτίριο δεν έχω ακόμα επαφή.

These alternatives change the emphasis or sound more marked, but they are possible.

So Greek word order often depends on:

• what is already known
• what is being emphasized
• the rhythm of the sentence

A simple pronunciation guide is:

Den EHO akóma epafí me ólous tous YÍtones sto kenúrio KTÍrio.

A few helpful notes:

• δεν sounds like then/den with a soft d sound
• έχω has a rough h/kh sound, not an English ch
• γείτονες begins with yi-
• κτίριο has the stress on κτί-

The written accent marks show you where the stress falls:

• έχω
• ακόμα
• επαφή
• όλους
• γείτονες
• καινούριο
• κτίριο

No, it sounds quite natural and neutral.

It is not slangy, but it is also not especially formal. You could use it in everyday conversation if you moved into a building and wanted to say that you haven’t gotten to know everyone yet.

So the overall register is:

• standard
• natural
• everyday

Yes, it most naturally describes where those neighbors are or which neighbors you mean:

• the neighbors in the new building

So the sentence is understood as:

• I don’t yet have contact with all the neighbors in the new building.

In practice, the final phrase helps identify the group of neighbors, not the location of the contact itself.
