Άφησα το δίπλωμά μου στο άλλο μπουφάν και έπρεπε να γυρίσω σπίτι.

Άφησα is the aorist form of αφήνω. In this sentence, it presents the action as a single completed event in the past: I left / I forgot behind.

A native English speaker will often notice that Greek chooses aspect very clearly here:

• Άφησα = one whole event
• άφηνα = I was leaving / used to leave / kept leaving

So Άφησα το δίπλωμά μου... means that at some point, the speaker realized they had left it in the other jacket.

In Greek, the unstressed possessive words μου, σου, του, της usually come after the noun, not before it.

So:

• το δίπλωμά μου = my license
• not το μου δίπλωμα

This is a very common Greek pattern:

• το σπίτι μου = my house
• η τσάντα σου = your bag
• ο φίλος της = her friend

So the Greek order is closer to the license my in structure, even though the natural English translation is my license.

This happens because μου is an enclitic: a little unstressed word that leans on the previous word.

The noun by itself is:

• δίπλωμα

But when you add μου, Greek often adds a second written accent if the noun is stressed early enough in the word. So:

• δίπλωμα
• δίπλωμά μου

This extra accent helps show the correct pronunciation rhythm. You will see the same thing in many similar phrases:

• το όνομά μου = my name
• ο άνθρωπός μου = my person / my partner
• τα πράγματά μου = my things

Yes. δίπλωμα can mean different things depending on context.

Common meanings include:

• diploma / degree
• license, especially a driver’s license

In this sentence, because the speaker had to go back home after leaving it in a jacket, δίπλωμα is naturally understood as something like a driver’s license or another important ID-type document.

So although the word looks like English diploma, the meaning here is broader.

στο is the contraction of:

• σε + το = στο

So στο άλλο μπουφάν literally means in/on/at the other jacket, and in natural English here: in the other jacket.

This contraction is extremely common:

• σε το σπίτι → στο σπίτι
• σε την τσάντα stays στην τσάντα
• σε τα βιβλία → στα βιβλία

So whenever you see στο, think σε + το.

Here άλλο means other, and because of the article το, the phrase means:

• το άλλο μπουφάν = the other jacket

Compare:

• το άλλο μπουφάν = the other jacket
• ένα άλλο μπουφάν = another jacket / a different jacket

So the article makes it specific. The speaker is not talking about just any different jacket, but about the other one.

μπουφάν is a loanword and is commonly treated as indeclinable in modern Greek. That means its form often does not change across cases.

So Greek shows the grammar through the words around it:

• το μπουφάν
• στο μπουφάν
• το άλλο μπουφάν

The article and adjective tell you the gender, number, and case, while μπουφάν itself stays the same.

This is normal for quite a few borrowed words in Greek.

Because Greek is showing two different kinds of past meaning.

• Άφησα = aorist → a single completed event
• έπρεπε = imperfect → an ongoing situation/state in the past

So the sentence separates:

1. the event: I left my license in the other jacket
2. the resulting necessity: I had to go back home

The need was not a single sharp action; it was a past situation that existed because of what happened. That is why έπρεπε is imperfect.

English often just uses simple past for both, but Greek makes the distinction more clearly.

That is because πρέπει / έπρεπε is often used impersonally in Greek.

Literally, it works more like:

• πρέπει = it is necessary
• έπρεπε = it was necessary

Then the να clause tells you who had to do what:

• έπρεπε να φύγω = I had to leave
• έπρεπε να γυρίσω σπίτι = I had to go back home

So even though the verb form itself is third person singular, the meaning in English becomes I had to, you had to, we had to, depending on the rest of the sentence.

After έπρεπε, Greek normally uses να + subjunctive.

So:

• έπρεπε να γυρίσω = I had to return / go back

Not:

• έπρεπε γύρισα ❌
• έπρεπε γυρίζω ❌

Also, γυρίσω is not a past indicative form. It is the aorist subjunctive form used after να.

A useful comparison:

• γύρισα = I returned / I went back
• να γυρίσω = to return / that I return / for me to return, depending on context

So after verbs like πρέπει, θέλω, μπορώ, έπρεπε, Greek typically uses this να + verb pattern.

Because the speaker is talking about one complete return home.

• να γυρίσω = to go back once, as a whole event
• να γυρίζω = to be going back repeatedly / habitually / in an ongoing way

Here the meaning is clearly a single action caused by the problem: the speaker had to go back home one time. So the aorist subjunctive is the natural choice.

Greek often uses σπίτι without an article to mean home as a destination.

So:

• πάω σπίτι = I’m going home
• γυρίζω σπίτι = I’m returning home
• έπρεπε να γυρίσω σπίτι = I had to go back home

This is very similar to English, where we say go home, not usually go to the home.

You can also say στο σπίτι in some contexts, but bare σπίτι is extremely common when the meaning is simply home.

No, Greek word order is fairly flexible, though this sentence is very natural and neutral as written.

The given order:

• Άφησα το δίπλωμά μου στο άλλο μπουφάν και έπρεπε να γυρίσω σπίτι.

sounds like straightforward narration.

You could rearrange parts for emphasis. For example:

• Έπρεπε να γυρίσω σπίτι, γιατί άφησα το δίπλωμά μου στο άλλο μπουφάν.

This changes the flow a bit, but not the core meaning.

So Greek word order is not random, but it is more flexible than English, especially when the endings and articles already make the grammatical roles clear.
