Μπορείτε να μου πείτε αν ισχύει η προσφορά και στο ηλεκτρονικό κατάστημα ή δεν υπάρχει πια απόθεμα;

Μπορείτε να μου πείτε literally means Can you tell me.

Breakdown:

• Μπορείτε = you can
  
  • from μπορώ = I can
  • μπορείτε is the 2nd person plural, but in Greek it is also used as the polite singular (you = sir/ma’am)
• να introduces the following verb, similar to to or a subjunctive-like structure in English
• μου = to me
• πείτε = say / tell

So the structure is:

• Μπορείτε = can you
• να πείτε = to tell / tell
• μου = me

Together: Can you tell me...

This is a very common polite way to ask for information.

In Greek, indirect object pronouns like μου often work as short unstressed forms placed before the verb.

So:

• μου = to me / me
• σου = to you
• του / της = to him / her
• μας = to us

In this sentence:

• να μου πείτε = to tell me

Greek usually prefers this compact pronoun structure instead of something more expanded. It is extremely common and natural.

αν here means whether / if.

In this sentence:

• να μου πείτε αν ισχύει... = tell me whether / if ... is valid / applies

This is not the same as a conditional if like If it rains, I’ll stay home.
Here, αν introduces an indirect yes/no question:

• whether the offer is valid in the online shop too

So the learner should understand αν here as:

• whether
• or if in the sense of I want to know if...

ισχύει means something like:

• is valid
• applies
• is in effect
• holds true

So:

• ισχύει η προσφορά = the offer is valid / applies

This verb is very common in formal or practical contexts:

• Ισχύει ακόμα; = Is it still valid?
• Ισχύει για όλους; = Does it apply to everyone?

In this sentence, it is asking whether the promotion still applies to the online store.

Because η προσφορά is the subject of ισχύει.

Structure:

• ισχύει η προσφορά = the offer applies / is valid

Here:

• η = the (feminine nominative singular)
• προσφορά = offer / promotion

Since the offer is the thing doing the applying / being valid, it stays in the nominative.

Here και means also / too, not simply and.

So:

• και στο ηλεκτρονικό κατάστημα = also in the online store

That is a very common use of και in Greek.

Examples:

• Θέλω και καφέ. = I want coffee too.
• Ισχύει και εδώ; = Does it apply here too?

So in this sentence, the speaker is asking whether the offer applies:

• in the physical store, presumably already known
• and also in the online store

στο is a contraction of:

• σε = in / at / to
• το = the

So:

• σε το becomes στο

That means:

• στο ηλεκτρονικό κατάστημα = in the online store

Breakdown:

• ηλεκτρονικό = electronic / online
• κατάστημα = shop / store

Literally, Greek says something like in the electronic store, but natural English is in the online store.

Yes. ή means or.

The sentence asks between two possible explanations:

1. Does the offer also apply in the online store?
2. Or is there no stock anymore?

So the speaker is basically saying:

• Can you tell me whether the offer also applies online, or is it no longer in stock?

It is a natural way to ask for clarification when two explanations are possible.

It means:

• there is no stock anymore
• or more naturally, it’s out of stock now

Breakdown:

• δεν = not
• υπάρχει = there is / exists
• πια = anymore / no longer
• απόθεμα = stock / inventory

So literally:

• there doesn’t exist stock anymore

Natural English:

• there’s no stock left anymore
• it’s out of stock now

Greek often leaves out the article in expressions of this kind, especially when speaking generally about availability or existence.

So:

• δεν υπάρχει πια απόθεμα = there is no stock anymore

This sounds natural in Greek. You could think of it as talking about stock in a general sense, not a specific stock.

English does something similar sometimes:

• There’s no food left
• There’s no time
• There’s no stock

So the lack of an article here is normal.

πια means:

• anymore
• no longer
• now any longer

It often appears in negative sentences:

• Δεν δουλεύει πια. = It doesn’t work anymore.
• Δεν μένει εδώ πια. = He/She doesn’t live here anymore.

By contrast, ακόμα usually means:

• still
• yet
• even

Examples:

• Ισχύει ακόμα; = Is it still valid?
• Δεν ήρθε ακόμα. = He/She hasn’t come yet.

So:

• πια = anymore / no longer
• ακόμα = still / yet

Greek word order is more flexible than English word order because Greek relies more on verb endings and case marking.

This sentence is structured very naturally for Greek:

• Μπορείτε να μου πείτε = Can you tell me
• αν ισχύει η προσφορά = whether the offer applies
• και στο ηλεκτρονικό κατάστημα = also in the online store
• ή δεν υπάρχει πια απόθεμα = or there is no stock anymore

English often prefers a slightly more tightly fixed order, but Greek can move pieces around for emphasis without becoming ungrammatical.

For example, Greek could rearrange parts of this sentence and still sound acceptable, though the emphasis would change.

Yes, it is polite and natural.

The politeness comes mainly from:

• Μπορείτε = polite you can
• the phrasing να μου πείτε = tell me
• the overall indirect structure

It sounds like something you could say to customer service, a store employee, or support staff.

A less polite or less formal version might use singular familiar forms, but this sentence is appropriately polite for speaking to someone you do not know well.

A rough pronunciation guide:

• ηλεκτρονικό ≈ ee-lek-tro-nee-KO
• κατάστημα ≈ ka-TA-stee-ma

Stress matters:

• ηλεκτρονικό
• κατάστημα

And in the full phrase:

• στο ηλεκτρονικό κατάστημα

The final -ν of στον is not present here because the word is στο, not στον.
That is because κατάστημα is neuter:

• το κατάστημα
• therefore στο κατάστημα

Technically, πείτε comes from λέω and can relate to say, but in this context tell is the better English translation.

So:

• Μπορείτε να μου πείτε... = Can you tell me...

Using say in English would sound less natural here:

• Can you say to me if... is not good English

So although the Greek verb may broadly cover areas that overlap with say/tell, the natural translation here is definitely tell me.
