Μπορείτε να μου πείτε αν στα διόδια έχει ακόμα πολλή ουρά;

Μπορείτε is the 2nd person plural form of μπορώ = I can.

So literally it means you (plural) can. In Greek, though, this form is also commonly used as a polite singular—like English Can you... when speaking politely to one person.

So Μπορείτε να μου πείτε... means:

• Can you tell me...
  or more literally:
• Are you able to tell me...

Greek does not use an infinitive the way English does. Instead, it often uses να + a verb form.

So where English says:

• Can you tell me...?

Greek says:

• Μπορείτε να μου πείτε;
• literally: Can you to-tell me?
  but naturally: Can you tell me?

Here, να introduces the verb πείτε in the subjunctive.

The verb here is from λέω = I say / I tell, but after να, Greek often uses the aorist subjunctive when talking about a single complete action.

So:

• να πείτε = to tell / to say as one complete act

This is more natural than using a present-style form here, because the speaker is asking for one piece of information.

Also, πείτε looks identical to the imperative form (say! / tell!), but here it is not an imperative. It is a subjunctive because it comes after να.

μου means to me.

So:

• να μου πείτε = to tell me

Greek object pronouns like μου, σου, του, της are usually short unstressed forms that come before the verb.

Compare:

• μου = to me / my
• here it is the indirect object: tell me

This word order is completely normal in Greek.

Here αν means whether / if in an indirect yes-no question.

So:

• να μου πείτε αν... = to tell me whether... / to tell me if...

This is not a condition like:

• If it rains, we’ll stay home.

Instead, it introduces the thing the speaker wants to know:

• whether there is still a long queue at the tolls

So in this sentence, αν is best understood as whether / if in the sense of I want to know if...

στα διόδια means at the tolls / at the toll booths / at the toll plaza.

It is made from:

• σε = at / to / in
• τα = the
• στα = the contracted form of σε τα

And:

• διόδια = tolls, toll booths, or the toll station area

Even though English often uses a singular expression like the toll booth or the toll plaza, Greek commonly uses the plural διόδια.

In Greek, διόδια is very often used as a plural noun to refer to the toll point as a whole—the toll booths, lanes, barriers, etc.

So Greek speakers naturally say:

• στα διόδια = at the tolls

Even if English might use:

• at the toll booth
• at the toll plaza
• at the toll station

So this is one of those cases where Greek and English package the idea differently.

Because διόδια is not the subject of the verb.

The structure is basically:

• στα διόδια = at the tolls → location
• έχει πολλή ουρά = there is a long queue

So έχει is singular because Greek is using it in the sense of:

• there is

And the thing that exists is:

• πολλή ουρά = a lot of queue / a long queue

Since ουρά is singular, the verb is singular too.

ακόμα here means still.

So:

• έχει ακόμα πολλή ουρά = there is still a long queue

It suggests that the queue may have already existed earlier, and the speaker wants to know whether it continues.

Depending on context, ακόμα can also mean even or yet, but here still is the correct meaning.

Because ουρά is a feminine singular noun, and the adjective must agree with it.

So:

• πολλή = feminine singular
• πολύ = neuter singular or adverbial form

Since:

• η ουρά = the queue
  is feminine, we need:
• πολλή ουρά = a lot of queue / a long queue

This is a very common point for learners, because πολύ is also used as an adverb meaning very / much, but here it is an adjective modifying a noun.

Literally, ουρά means tail.

But very commonly, it also means:

• queue
• line

In this sentence, it refers to a line of cars waiting at the tolls, so a natural English translation would be:

• a long queue
• a big line
• heavy backup at the tolls

So the image is basically of traffic lined up one behind another.

Greek word order is fairly flexible, although some orders sound more natural than others.

This sentence:

• Μπορείτε να μου πείτε αν στα διόδια έχει ακόμα πολλή ουρά;

is perfectly natural.

But Greek could also reshuffle parts for emphasis, for example:

• Μπορείτε να μου πείτε αν έχει ακόμα πολλή ουρά στα διόδια;

That version means the same thing. The main difference is emphasis and rhythm.

In the original, στα διόδια appears early inside the αν clause, which makes the location clear right away.

In Greek, the question mark is written as ;.

So:

• Greek ; = English ?

This often surprises learners, because in English ; is a semicolon, but in Greek it marks a direct question.

So the final punctuation here is completely normal Greek spelling.
