Μένουν μόνο δύο λεπτά μέχρι τη συνάντηση.

Greek often does not need an equivalent of English there are in this kind of sentence. Instead, it simply uses the main verb directly:

• Μένουν μόνο δύο λεπτά = Only two minutes remain / are left

So the sentence is more direct than the usual English structure.

δύο means two, and λεπτά is the plural of λεπτό, meaning minute.

A few useful points:

• λεπτό is a neuter noun
• Its plural is λεπτά
• After δύο, the noun is plural

So δύο λεπτά is simply two minutes.

It is the nominative plural, because it is the subject of the verb Μένουν.

With neuter nouns, the nominative plural and accusative plural look the same, so λεπτά could be either in other contexts. Here, because it is the thing that remains, it is nominative.

Because μόνο is focusing on the amount: only two minutes.

In this position, it naturally limits δύο λεπτά. Greek word order is flexible, but this is the most straightforward and natural placement if you want to emphasize the small amount of time remaining.

Here μέχρι means until.

It is followed by τη συνάντηση, which is in the accusative. So:

• μέχρι = until
• τη συνάντηση = the meeting, in the accusative

That is the normal pattern in Modern Greek.

The full form of the feminine accusative singular article is την, but in standard Modern Greek the final -ν is often dropped before certain consonants.

Since συνάντηση begins with σ, you normally get:

• τη συνάντηση

You may still hear or see την in some speech or writing, but τη συνάντηση is completely normal and standard here.

You can tell from the article τη and from the noun ending.

• Dictionary form: η συνάντηση
• Accusative singular: τη συνάντηση

So the noun is feminine, and the article changes form to match its role in the sentence.

Greek word order is fairly flexible. This sentence could be rearranged, but each version changes the emphasis a little.

For example:

• Μένουν μόνο δύο λεπτά μέχρι τη συνάντηση.
  Neutral and natural.
• Μόνο δύο λεπτά μένουν μέχρι τη συνάντηση.
  Stronger emphasis on only two minutes.
• Μέχρι τη συνάντηση μένουν μόνο δύο λεπτά.
  Puts the time limit first.

So the original sentence is not the only possible order, but it is a very natural one.

Because the sentence describes the situation right now. At this moment, only two minutes remain before the meeting. So the present tense is exactly what Greek wants here.

It is not talking about the meeting itself as present; it is talking about the current amount of remaining time.

Yes. Απομένουν also means remain / are left, and it is very common in this context.

The difference is small:

• Μένουν μόνο δύο λεπτά = natural, everyday
• Απομένουν μόνο δύο λεπτά = also natural, sometimes a bit more explicit or slightly more formal

Both are correct.

The stressed syllables are:

• ΜΈ-νουν
• μο-ΝΟ
• ΔΥ-ο
• λε-ΠΤΑ
• μέ-ΧΡΙ
• τη
• συ-ΝΑ-ντη-ση

A rough pronunciation guide might be:

MEN-oon MO-no THEE-o lep-TA MEH-khri ti sih-NAN-di-si

The main thing to notice is that Greek stress is very important and must stay on the correct syllable.
