Κοντεύω να αργήσω στη συνάντηση, οπότε ας μην καθίσουμε άλλο στο καφέ.

κοντεύω να + verb means to be close to doing something, to be about to, or to be on the verge of.

So κοντεύω να αργήσω means something like:

• I’m close to being late
• I’m about to be late
• I’m nearly late

It does not literally mean physical movement, even though κοντεύω originally has the idea of coming near.

Because after να, Greek normally uses a subjunctive form, not the plain indicative form.

Here:

• αργώ = I am late / I am being late / I’m running late depending on context
• να αργήσω = to be late / to end up late in the subjunctive pattern

The aorist form αργήσω is very natural here because the speaker is thinking of becoming late as a single result or event.

A learner-friendly way to think of it is:

• κοντεύω να αργήσω = I’m close to ending up late

Greek often leaves subject pronouns out because the verb ending already shows the person.

Here:

• κοντεύω = I am close
• καθίσουμε = we sit / we stay in this construction

So Greek does not need εγώ or εμείς unless the speaker wants extra emphasis or contrast.

For example:

• Εγώ κοντεύω να αργήσω would sound more like I’m the one who’s about to be late

στη is the contraction of σε + τη(ν).

So:

• σε τη συνάντηση → στη συνάντηση

With words like αργώ and events such as meetings, classes, work, appointments, Greek often uses σε:

• άργησα στη δουλειά = I was late for work
• άργησε στο μάθημα = he/she was late for class
• άργησα στο ραντεβού = I was late for the appointment

So στη συνάντηση here means for the meeting / to the meeting.

Here οπότε means so, therefore, or so then.

It connects the first idea to the result:

• I’m close to being late for the meeting, so...

A useful note: οπότε can also mean when or whenever in other contexts, but not in this sentence.

ας is used to make a suggestion, roughly like let’s in English.

So:

• ας καθίσουμε = let’s sit / let’s stay seated
• ας μην καθίσουμε = let’s not sit / let’s not stay

Greek does not have a single word that exactly equals English let’s, so ας + subjunctive is the usual way to express that idea.

Because μην is used to negate subjunctive and command-like forms, while δεν negates ordinary statements.

Here:

• ας ... καθίσουμε is a suggestion structure
• so the negative must be μην

Compare:

• Δεν καθόμαστε άλλο. = We aren’t staying any longer.
  (statement)
• Ας μην καθίσουμε άλλο. = Let’s not stay any longer.
  (suggestion)

This is a very common Greek pattern:

• να μην...
• ας μην...
• μην... for negative commands

It can, but in context it can also mean stay seated or remain sitting.

In this sentence, because they are already in the café and the phrase includes άλλο, the meaning is closer to:

• let’s not stay any longer
• let’s not keep sitting here

So this is not really about the physical action of lowering yourself into a chair. It is about remaining there.

This is an aspect question.

• καθίσουμε is the aorist form
• καθόμαστε would be a present/continuous form

With ας μην καθίσουμε άλλο, the speaker is treating the idea of staying longer as a single whole decision: let’s not remain any further.

If someone said ας μην καθόμαστε άλλο, that would also be understandable, but it would put more focus on the ongoing state of sitting.

So the sentence’s version sounds natural and decisive.

Right — here άλλο means more, any longer, or any more, not other.

This is very common in Greek.

Examples:

• μη μιλάς άλλο = don’t talk any more
• δεν αντέχω άλλο = I can’t take it any longer
• ας μην καθίσουμε άλλο = let’s not stay any longer

So άλλο often has a time-related meaning like further or longer in these contexts.

Because το καφέ meaning the café is treated as a neuter noun, so:

• το καφέ
• στο καφέ

But ο καφές means coffee as a drink, and that is masculine:

• ο καφές
• τον καφέ
• στον καφέ would normally relate to the masculine form

So the article tells you which word you are dealing with:

• στο καφέ = in/at the café
• στον καφέ = in/to the coffee only in very unusual contexts, or more realistically part of a phrase involving ο καφές

Yes, στο καφέ is natural and understandable.

That said, many speakers might also say:

• στην καφετέρια = at the café / coffee shop
• ας φύγουμε από το καφέ = let’s leave the café

So the original sentence is fine, but Greek offers a few natural alternatives depending on style and region. The important point is that στο καφέ refers to the place, not the drink.
