Αν ενδιαφέρεσαι για το μάθημα, μπορώ να σου στείλω το νέο κείμενο μετά.

Yes. Αν means if, and ενδιαφέρεσαι means you are interested.

So:

• Αν = if
• ενδιαφέρεσαι = you’re interested

This is a very normal Greek structure for a real or possible condition:

• Αν έχεις χρόνο, έλα. = If you have time, come.
• Αν θέλεις, μπορώ να βοηθήσω. = If you want, I can help.

Greek does not need a separate word for you here, because the verb ending already shows that it is you.

Ενδιαφέρεσαι is:

• present tense
• 2nd person singular
• from the verb ενδιαφέρομαι = to be interested

So it literally means you are interested or you take an interest.

A useful thing to notice is that the dictionary form is ενδιαφέρομαι, not ενδιαφέρω in this meaning. This verb is normally used in the middle/passive-looking form, even though its meaning is active in English.

Examples:

• Ενδιαφέρομαι για την ιστορία. = I’m interested in history.
• Ενδιαφέρεται για τη μουσική. = He/She is interested in music.

Because ενδιαφέρομαι normally takes για to introduce the thing or subject you are interested in.

So:

• ενδιαφέρομαι για κάτι = to be interested in something

Examples:

• Ενδιαφέρομαι για τα ελληνικά. = I’m interested in Greek.
• Ενδιαφέρεσαι για αυτή τη δουλειά; = Are you interested in this job?

For an English speaker, this is something to learn as part of the verb pattern:

• interested in something
• ενδιαφέρομαι για something

Greek and English just use different prepositions here.

Yes. Greek uses the definite article much more often than English.

So για το μάθημα can mean:

• about the lesson
• about the class
• about the course

depending on context.

In many cases where English might say for class or about class, Greek naturally uses the article:

• Πάω στο σχολείο. = I’m going to school.
• Μου αρέσει η μουσική. = I like music.
• Διαβάζω το βιβλίο. = I’m reading the book.

Here, το μάθημα probably refers to a specific lesson or course already understood from context.

This is a very common Greek structure:

• μπορώ = I can
• να = particle introducing the following verb
• σου = to you
• στείλω = send

So:

μπορώ να σου στείλω = I can send you

A key pattern is:

• μπορώ να + verb

Examples:

• Μπορώ να έρθω. = I can come.
• Μπορώ να μιλήσω. = I can speak.
• Μπορώ να σου πω. = I can tell you.

After να, Greek often uses either the imperfective or perfective verb form, depending on the meaning.

Here:

• στέλνω = I send / I am sending
• στείλω = perfective form, often used after να

In μπορώ να σου στείλω, the speaker means I can send it to you as a single complete action. That is why στείλω is natural.

Compare:

• Μπορώ να σου στείλω το αρχείο. = I can send you the file.
  (one complete action)

• Μπορώ να σου στέλνω υλικό κάθε εβδομάδα. = I can send you material every week.
  (repeated/ongoing action)

So στείλω is not a normal present-tense form by itself here; it is the form used after να for a complete action.

Σου means to you.

It is the weak form of the pronoun and is used for an indirect object:

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

So:

• να σου στείλω = to send to you / to send you

Greek usually puts these weak pronouns before the verb:

• Σου γράφω. = I’m writing to you.
• Θα σου πω. = I’ll tell you.
• Μπορώ να σου στείλω... = I can send you...

English often puts you after the verb, but Greek places σου before it.

Yes, but it would sound different.

• να σου στείλω = the normal, neutral way
• να στείλω σε εσένα = more emphatic, like to you specifically

Examples:

• Θα σου δώσω το βιβλίο. = I’ll give you the book.
• Θα δώσω το βιβλίο σε εσένα, όχι σε αυτόν. = I’ll give the book to you, not to him.

So in your sentence, σου is the natural everyday choice.

Νέο means new, and it agrees with κείμενο in gender, number, and case.

Here:

• κείμενο is neuter singular
• the object is in the accusative
• so the adjective is also neuter singular accusative
• therefore: νέο

Full phrase:

• το νέο κείμενο = the new text

Agreement examples:

• ο νέος μαθητής = the new male student
• η νέα μαθήτρια = the new female student
• το νέο κείμενο = the new text

Κείμενο usually means text in a broad sense.

Depending on context, it could mean:

• a text for study
• a passage
• a written piece
• an article
• a document

In a learning context like μάθημα, it most likely means something like:

• the new text
• the new passage
• the new reading

So the exact English translation depends on the situation, even though the Greek word is the same.

Here μετά means later.

So:

• μπορώ να σου στείλω το νέο κείμενο μετά = I can send you the new text later.

Greek μετά can mean different things depending on structure:

1. μετά on its own = later / afterwards

   • Θα μιλήσουμε μετά. = We’ll talk later.

2. μετά από

   • noun = after
   • Μετά από το μάθημα = after the lesson

In your sentence, because it stands alone at the end, it means later.

Yes. Greek word order is fairly flexible, and moving μετά changes the emphasis slightly, not the basic meaning.

For example:

• Μπορώ να σου στείλω το νέο κείμενο μετά.
• Μπορώ μετά να σου στείλω το νέο κείμενο.
• Μετά μπορώ να σου στείλω το νέο κείμενο.

All are possible, but they do not sound exactly the same.

The original version puts μετά at the end, which feels very natural for later and gives it a light final emphasis.

Because Greek is a pro-drop language. The verb endings usually show the subject clearly, so subject pronouns are often omitted.

In this sentence:

• ενδιαφέρεσαι already means you are interested
• μπορώ already means I can

So Greek does not need:

• εσύ = you
• εγώ = I

You would only add them for emphasis or contrast:

• Αν εσύ ενδιαφέρεσαι, εγώ μπορώ να βοηθήσω.
  = If you are interested, I can help.

Without that emphasis, leaving them out is more natural.

As written, it is singular informal:

• ενδιαφέρεσαι = you (singular, informal) are interested
• σου = to you (singular or plural form can look the same here, depending on context, but the verb tells us singular)

For plural or polite you, Greek would use 2nd person plural:

• Αν ενδιαφέρεστε για το μάθημα, μπορώ να σας στείλω το νέο κείμενο μετά.

Changes:

• ενδιαφέρεσαι → ενδιαφέρεστε
• σου → σας

So that version can mean either:

• if you all are interested
• if you are interested (polite singular)

Because the sentence begins with a conditional clause:

• Αν ενδιαφέρεσαι για το μάθημα = If you’re interested in the lesson/course
• μπορώ να σου στείλω το νέο κείμενο μετά = I can send you the new text later

When this kind of clause comes first, Greek normally separates it with a comma, just as English often does.

So the structure is:

• condition first
• main clause second

That is why the comma is there.
