Σήμερα φοράω μπουφάν με κουκούλα, γιατί βρέχει και δεν έχω ομπρέλα.

Greek word order is fairly flexible, so putting Σήμερα first is very natural when the speaker wants to set the time frame right away.

So:

• Σήμερα φοράω μπουφάν... = Today I’m wearing a jacket...

You could also hear other orders, such as:

• Φοράω μπουφάν σήμερα...

But starting with Σήμερα sounds very natural because it gives the context first.

Greek often leaves out subject pronouns when they are not needed. The verb ending already shows who the subject is.

• φοράω = I wear / I am wearing
• φοράς = you wear
• φοράει = he/she/it wears

So εγώ is usually unnecessary unless you want emphasis or contrast:

• Εγώ φοράω μπουφάν, αλλά αυτός όχι. = I’m wearing a jacket, but he isn’t.

In your sentence, just φοράω is the normal choice.

It can mean both, depending on context.

Greek present tense often covers both:

• a general habit: I wear
• something happening now: I am wearing

In this sentence, because of Σήμερα and the weather context, φοράω is understood as I’m wearing.

Also, you may see φορώ instead of φοράω. Both are used. Φοράω is very common in everyday speech.

Because Greek, like English, does not always use an article with an indefinite noun.

• φοράω μπουφάν = I’m wearing a jacket
• φοράω το μπουφάν = I’m wearing the jacket

So the lack of an article makes μπουφάν indefinite here.

Also, μπουφάν is a very common loanword in Greek and is usually treated as an indeclinable noun.

Με means with, so:

• μπουφάν με κουκούλα = jacket with a hood / hooded jacket

This is a common Greek way to describe something by one of its features:

• καφές με γάλα = coffee with milk
• σπίτι με κήπο = house with a garden

There is no article before κουκούλα because the phrase is describing the type of jacket, not referring to a specific hood.

Γιατί means because in this sentence.

It can also mean why in a question:

• Γιατί βρέχει; = Why is it raining?

But in a statement like this one, it means because:

• ...γιατί βρέχει... = ...because it’s raining...

So Greek uses the same word for both why and because, and the context tells you which meaning is intended.

Because γιατί introduces an explanation: the second part gives the reason for the first part.

• Σήμερα φοράω μπουφάν με κουκούλα, γιατί βρέχει...

In normal written Greek, a comma before γιατί is very common when it introduces a reason clause.

Greek uses βρέχει as an impersonal verb, just like English uses it rains / it’s raining.

• βρέχει literally corresponds to it rains / it is raining

But there is no real subject doing the raining. English uses dummy it; Greek simply uses the verb by itself.

Other weather expressions work similarly:

• χιονίζει = it is snowing
• φυσάει = it is windy / the wind is blowing

Because Greek normally expresses possession with έχω = I have.

So:

• δεν έχω ομπρέλα = I don’t have an umbrella

That is the most natural way to say it.

Greek could express lack in other ways in special contexts, but with everyday possession, έχω / δεν έχω is the standard pattern.

For the same reason there is no article before μπουφάν: the noun is indefinite.

• δεν έχω ομπρέλα = I don’t have an umbrella
• δεν έχω την ομπρέλα = I don’t have the umbrella

So ομπρέλα here means an umbrella, not a specific one already known to the listener.

Here και is the normal conjunction and:

• γιατί βρέχει και δεν έχω ομπρέλα = because it’s raining and I don’t have an umbrella

It simply links two reasons or two related facts.

Greek και is extremely common and usually means:

• and
• sometimes also / too, depending on position and context

But in this sentence, plain and is the best understanding.

Yes. Greek allows several word orders, although some sound more natural in certain situations.

For example, these are possible:

• Σήμερα φοράω μπουφάν με κουκούλα, γιατί βρέχει και δεν έχω ομπρέλα.
• Φοράω σήμερα μπουφάν με κουκούλα, γιατί βρέχει και δεν έχω ομπρέλα.
• Γιατί βρέχει και δεν έχω ομπρέλα, σήμερα φοράω μπουφάν με κουκούλα.

The first version is the most natural, neutral one.

Greek word order is often used to highlight:

• time
• contrast
• emphasis
• what is new information

So yes, the order can change, but not all versions sound equally natural in everyday speech.

A simple pronunciation guide is:

• Σήμερα ≈ SEE-me-ra
• φοράω ≈ fo-RA-o
• μπουφάν ≈ boo-FAN
• με κουκούλα ≈ me koo-KOO-la
• γιατί ≈ ya-TEE
• βρέχει ≈ VRE-hi
• δεν έχω ≈ then E-ho
• ομπρέλα ≈ om-BRE-la

A few useful pronunciation points:

• μπ at the beginning of a word is usually pronounced like b
• ου sounds like oo
• αι sounds like e
• χ in έχω is a rough sound, like the ch in German Bach or Scottish loch
• χ in βρέχει is softer because it comes before e

The stressed syllable is the one marked by the accent:

• σημερα
• φοράω
• μπουφάν
• κουκούλα
• γιατί
• βρέχει
• έχω
• ομπρέλα
