Τον χειμώνα δεν ανοίγω συχνά την μπαλκονόπορτα, γιατί κάνει κρύο.

Τον χειμώνα means in winter or during the winter.

Greek often uses the accusative case for expressions of time, especially when meaning during a period of time. So:

• τον χειμώνα = in winter / during the winter
• literally, it looks like the winter in the accusative

This is a very common time expression pattern in Greek.

Because after the preposition-like time use during/in, Greek uses the accusative, not the nominative.

Compare:

• ο χειμώνας = winter (subject form, nominative)
• τον χειμώνα = in winter / during winter (accusative)

So the ending changes because the noun is not the subject here.

Very often, yes. Greek commonly uses the definite article with seasons, times, and many general expressions where English might not.

So Greek says:

• τον χειμώνα = in winter
• το καλοκαίρι = in summer
• την άνοιξη = in spring
• το φθινόπωρο = in autumn

For an English speaker, this can feel unusual because English usually drops the in this kind of phrase.

Yes, in everyday spoken Greek you may hear το χειμώνα quite often. However:

• τον χειμώνα is the more traditional/full form
• το χειμώνα is very common in speech and informal usage

A learner should recognize both. If you want a safe standard form, τον χειμώνα is a good choice.

Δεν is the basic word for not before a verb in Greek.

So:

• ανοίγω = I open / I am opening
• δεν ανοίγω = I do not open / I am not opening

In Greek, δεν usually comes directly before the verb:

• δεν τρώω = I do not eat
• δεν πάω = I am not going / I don't go
• δεν ανοίγω = I do not open

Because the Greek present tense is often used for habitual actions or things that are generally true.

Here, δεν ανοίγω συχνά means:

• I don’t often open
• not just right now, but as a general habit in winter

This is similar to English present simple:

• In winter, I don’t often open the balcony door.

So Greek present tense works very naturally here.

Because ανοίγω and ανοίξω belong to different aspect patterns.

• ανοίγω = imperfective, ongoing/repeated/habitual
• ανοίξω = perfective stem, usually used in forms referring to a single complete action, often with subjunctive or future contexts

In this sentence, the speaker is talking about a repeated habit, not one complete opening event. So ανοίγω is the right choice.

You would see ανοίξω in sentences like:

• Θα ανοίξω την πόρτα. = I will open the door.
• Να ανοίξω την πόρτα; = Shall I open the door?

But here the meaning is habitual: I don’t often open..., so ανοίγω fits.

Συχνά means often / frequently.

In this sentence:

• δεν ανοίγω συχνά την μπαλκονόπορτα
• I don’t often open the balcony door

Greek adverbs like συχνά are fairly flexible in position, but the placement here is very natural. It comes after the verb and before the object.

You may also hear slightly different word orders depending on emphasis, but this version is standard and easy to understand.

Because την μπαλκονόπορτα is the direct object of ανοίγω.

You open what?
→ the balcony door

So the noun takes the accusative singular form:

• nominative: η μπαλκονόπορτα
• accusative: την μπαλκονόπορτα

In this particular noun, the form of the noun itself stays the same, but the article shows the case clearly:

• η = nominative feminine singular
• την = accusative feminine singular

Μπαλκονόπορτα is a compound noun meaning balcony door or often a glass door leading to a balcony.

It is made from:

• μπαλκόνι = balcony
• πόρτα = door

In compounds, Greek often combines words into one noun. So μπαλκονόπορτα is a very normal everyday word.

Because κάνει κρύο is the normal idiomatic way to say it is cold when talking about the weather.

Literally, it looks like it makes cold, but that is just how Greek expresses weather conditions.

Common weather expressions include:

• κάνει κρύο = it is cold
• κάνει ζέστη = it is hot
• κάνει καλό καιρό = the weather is good

You might say είναι κρύο for an object, place, or specific thing:

• Το δωμάτιο είναι κρύο. = The room is cold.

But for weather, κάνει κρύο is the usual expression.

Here, γιατί means because and introduces the reason:

• ..., γιατί κάνει κρύο.
• ..., because it’s cold.

But γιατί can also mean why? in a question:

• Γιατί δεν ανοίγεις την πόρτα;
• Why aren’t you opening the door?

So the meaning depends on the sentence:

• in a statement: often because
• in a question: often why

Context tells you which one it is.

Because the sentence has a main clause followed by a reason clause:

• Τον χειμώνα δεν ανοίγω συχνά την μπαλκονόπορτα,
• γιατί κάνει κρύο.

The comma separates the main statement from the explanation/reason. This is very common in Greek punctuation.

Yes. Greek word order is more flexible than English, although not completely free.

The given sentence is very natural:

• Τον χειμώνα δεν ανοίγω συχνά την μπαλκονόπορτα, γιατί κάνει κρύο.

But you could also move parts around for emphasis, for example:

• Δεν ανοίγω συχνά την μπαλκονόπορτα τον χειμώνα, γιατί κάνει κρύο.

This still means basically the same thing, but the focus can shift slightly. For learners, the original order is an excellent neutral model.

At the start of a Greek word, μπ is usually pronounced like b in ball.

So:

• μπαλκονόπορτα sounds roughly like balkonóporta

This is important because Greek uses μπ to represent the b sound in many words.

The stressed syllables are:

• Τον χειμώνα
• ανοίγω
• συχνά
• μπαλκονόπορτα
• γιατί
• κρύο

Stress matters in Greek, so it is worth noticing the accent marks and learning to say the stressed syllable clearly.
