Μπορείς να μου πεις αν το θυροτηλέφωνο δουλεύει ή αν πρέπει να κατέβω στην είσοδο;

Greek often omits subject pronouns because the verb ending already shows who the subject is.

• Μπορείς = you can
• κατέβω = I go down / I should go down in this context

So Greek does not need to say εσύ for you or εγώ for I unless the speaker wants extra emphasis or contrast.

It literally means something like Can you tell me.

Breakdown:

• Μπορείς = you can
• να = a particle used before subjunctive-type verb forms
• μου = to me
• πεις = say / tell

So the structure is:

Μπορείς να μου πεις = Can you tell me

This is a very common Greek way to ask someone for information.

πεις is the form normally used here after να, from the verb λέω.

In this sentence, the speaker means one complete act of telling:
Can you tell me...?

That is why Greek prefers να πεις rather than a form meaning ongoing or repeated telling.

Very roughly:

• να πεις = to say/tell once, as a complete act
• να λες = to be saying / to say repeatedly / habitually

So Μπορείς να μου πεις... is the natural choice.

μου means to me.

In Greek, short object pronouns like μου, σου, του, της, μας often appear before the verb.

So:

• να μου πεις = to tell me

This word order is completely normal in Modern Greek.

Here αν means whether.

So:

• αν το θυροτηλέφωνο δουλεύει = whether the intercom works
• αν πρέπει να κατέβω στην είσοδο = whether I need to go down to the entrance

This is a very common use of αν to introduce an indirect yes/no question.

Because the sentence gives two alternatives:

• αν το θυροτηλέφωνο δουλεύει
• ή αν πρέπει να κατέβω στην είσοδο

In English, we often say whether X or Y, and sometimes we omit the second whether. Greek often repeats αν for clarity and balance.

So both of these ideas are being linked:

• whether the intercom works
• or whether I should go downstairs to the entrance

Το θυροτηλέφωνο means the intercom or the door-entry phone.

It is a compound word:

• θύρα / θύρο- = door
• τηλέφωνο = telephone

In everyday use, it refers to the system used at a building entrance so someone upstairs can speak to a visitor downstairs.

It is neuter singular, which is why it takes το.

Because θυροτηλέφωνο is a neuter singular noun.

Greek articles must agree with the noun in gender, number, and case.

Here:

• το = neuter singular nominative/accusative article
• θυροτηλέφωνο = neuter singular

So το θυροτηλέφωνο is the correct form.

Yes. Δουλεύει literally means works, but with machines and devices it means functions / is working.

So:

• το θυροτηλέφωνο δουλεύει = the intercom works / is working

This is very natural Greek. You can use δουλεύω for many devices:

• Το κινητό δεν δουλεύει. = The phone isn’t working.
• Το ασανσέρ δουλεύει; = Is the elevator working?

Because κατέβω refers to one single action: going down once.

Here the speaker means:

Do I need to go down now to the entrance?

That is why Greek uses the form κατέβω after πρέπει να.

Compare the general idea:

• να κατέβω = go down once, as a complete action
• να κατεβαίνω = be going down / go down regularly or repeatedly

In this sentence, the one-time action is what makes sense.

Στην είσοδο means to the entrance or at the entrance, depending on context.

It comes from:

• σε = to / at / in
• την = the
• είσοδο = entrance

σε + την contracts to στην.

So:

• στην είσοδο = to the entrance / at the entrance

In this sentence, because of κατέβω (go down), the meaning is clearly to the entrance.

The dictionary form is η είσοδος.

But after σε (to / at / in), Greek uses the accusative case:

• nominative: η είσοδος
• accusative: την είσοδο

And since σε την becomes στην, we get:

• στην είσοδο

So the form changes because of Greek case grammar.

Yes. Μπορείς is second person singular, so it is used when speaking to one person informally.

A more formal or plural version would be:

• Μπορείτε να μου πείτε αν το θυροτηλέφωνο δουλεύει ή αν πρέπει να κατέβω στην είσοδο;

So:

• Μπορείς = informal singular
• Μπορείτε = formal singular or plural

In Greek, the question mark is written as ;

So:

• Greek ; = English ?

This is one of the first punctuation differences learners notice in Greek.

Approximately:

thee-ro-tee-LE-fo-no

A few useful points:

• θ sounds like th in think
• υ is pronounced like ee
• the stress is on λέ

So the stress falls here:

θυροτηλέφωνο

Yes, very normal.

Greek word order is often more flexible than English, but this sentence is completely natural:

Μπορείς να μου πεις αν το θυροτηλέφωνο δουλεύει ή αν πρέπει να κατέβω στην είσοδο;

A learner-friendly way to see it is:

• Can you tell me
• whether the intercom works
• or whether I need to go down to the entrance?

So even though some small things, like μου before the verb, may look unusual from an English perspective, the sentence is standard everyday Greek.
