Αν δεν αργήσει το τραμ, θα προλάβω την πρωινή σύσκεψη.

It is a future real condition:

• Αν δεν αργήσει το τραμ = the condition
• θα προλάβω την πρωινή σύσκεψη = the result

A very common Greek pattern is:

αν + verb, θα + verb

So this sentence means that one future event depends on another future event.

Αν means if.

It introduces the condition: if the tram is not late / if the tram doesn’t run late.

You may also see εάν, which is a more formal version of αν. In everyday speech, αν is the normal choice.

Greek often omits subject pronouns when they are clear from the verb ending.

In θα προλάβω, the ending -ω already tells you the subject is I.

So Greek does not need εγώ here unless you want emphasis:

• θα προλάβω = I will make it / I will catch it in time
• εγώ θα προλάβω = I will make it, possibly contrasting with someone else

Because standard Greek normally does not use θα in this kind of if-clause.

So Greek says:

• Αν δεν αργήσει το τραμ, θα προλάβω...

not:

• Αν δεν θα αργήσει το τραμ...

The future marker θα goes in the main clause, not in the condition clause, in this normal future-condition pattern.

Αργήσει is the perfective non-past form of αργώ. Many learners also meet it under the traditional label aorist subjunctive form.

Here it is used after αν to refer to a single future event: whether the tram ends up being late this time.

That is why Greek uses αργήσει instead of a plain present form like αργεί.

This is a very common question, because learners often associate forms like αργήσει with structures that take μη(ν).

But with αν in ordinary conditional clauses, Greek normally uses δεν:

• Αν δεν αργήσει... = correct

So even though the verb form may look like what textbooks call a subjunctive-type form, the negation here is still δεν.

Here αργήσει means be late, run late, or be delayed.

With transport, Greek commonly uses αργώ this way:

• Το τραμ αργεί = the tram is late / the tram is delayed
• Αν δεν αργήσει το τραμ... = if the tram is not late / if the tram doesn’t get delayed

So the focus is on the tram failing to arrive on time.

Προλάβω comes from προλαβαίνω and usually means something like:

• manage to make it in time
• catch
• get there before it is too late

In this sentence, θα προλάβω την πρωινή σύσκεψη means that the speaker will make it in time for the morning meeting.

It is not just about physically arriving somewhere; it has the idea of being in time.

Because θα προλάβω is the normal way to express a single future result here.

• θα προλάβω = I will make it in time
• προλαβαίνω = I make it / I am making it / I usually manage

The form with θα points to the future, and προλάβω gives the sense of a complete result: the speaker either will make the meeting in time or will not.

Because it is the direct object of προλάβω.

The noun σύσκεψη is feminine singular, and here it is in the accusative because it is what the speaker hopes to catch or make in time for.

So the whole phrase agrees in gender, number, and case:

• την = feminine singular accusative article
• πρωινή = feminine singular accusative adjective
• σύσκεψη = feminine singular accusative noun

Compare the nominative form:

• η πρωινή σύσκεψη = the morning meeting

Because the sentence refers to a specific meeting, not just any meeting.

So Greek uses the definite article:

• την πρωινή σύσκεψη = the morning meeting

If it were indefinite, Greek would use μια:

• μια πρωινή σύσκεψη = a morning meeting

Greek uses articles very regularly, so keeping them is important.

Yes. Τραμ is treated as a neuter noun in Modern Greek.

It is also usually indeclinable, which means the noun itself does not change form much. The article shows its grammatical role:

• το τραμ = the tram

In this sentence, το τραμ is the subject of αργήσει.

Greek word order is more flexible than English word order.

So both of these are possible:

• Αν δεν αργήσει το τραμ...
• Αν το τραμ δεν αργήσει...

The version in your sentence is very natural. Greek often places the verb before the subject.

One important point: δεν normally goes directly before the verb, so you get δεν αργήσει, not a different placement.

In normal writing, yes, a comma is very commonly used when the αν-clause comes first:

• Αν δεν αργήσει το τραμ, θα προλάβω την πρωινή σύσκεψη.

It helps separate the condition from the result.

If the main clause came first, punctuation could be a bit more flexible, but with this order, the comma is the standard choice.
