Το βράδυ βάζω τη γλάστρα μέσα, γιατί έξω φυσάει πολύ.

Yes, το is the neuter form of the, but in Greek, expressions of time often use the article plus a noun in the accusative:

• το πρωί = in the morning
• το μεσημέρι = at noon / in the afternoon
• το βράδυ = in the evening / at night

So Το βράδυ is a fixed time expression, not literally just the evening in this sentence.

Βάζω is the present tense form meaning I put / I am putting. In Greek, the present tense can cover both:

• a habitual action: I put
• an action happening now: I am putting

In this sentence, because of Το βράδυ, it most naturally sounds like a habitual action:

• Το βράδυ βάζω τη γλάστρα μέσα
  = In the evening, I bring/put the flowerpot inside

So Greek does not need a separate am putting form here.

Because γλάστρα is the direct object of βάζω.

• η γλάστρα = the flowerpot, as the subject
• τη(ν) γλάστρα = the flowerpot, as the object

Compare:

• Η γλάστρα είναι έξω. = The flowerpot is outside.
• Βάζω τη γλάστρα μέσα. = I put the flowerpot inside.

So τη γλάστρα is in the accusative case.

Both are related to the same article: την.

In Modern Greek, the final -ν in την is often dropped before many consonants in normal writing and speech:

• τη γλάστρα
• την γλάστρα

Both may be seen, but τη γλάστρα is very common and natural.

A simple learner rule is:

• before vowels or certain consonants, την is often kept
• before many other consonants, τη is common

So here, τη γλάστρα is perfectly normal.

Here μέσα means inside / indoors.

So:

• βάζω τη γλάστρα μέσα = I put the flowerpot inside

It is functioning as an adverb of place. Greek often uses μέσα very naturally without adding extra words like into the house, if the context is clear.

Related words:

• μέσα = inside
• έξω = outside

Because Greek often prefers to mention the noun directly if it is already the object:

• βάζω τη γλάστρα μέσα = I put the flowerpot inside

You could also use a pronoun in other contexts, but Greek very often keeps things simple and direct by naming the object itself. So this sentence is completely natural.

Yes. Γιατί can mean both:

• because
• why

The meaning depends on context and punctuation.

In this sentence:

• ..., γιατί έξω φυσάει πολύ.
• ..., because outside it’s very windy / the wind is blowing a lot.

As a question:

• Γιατί βάζεις τη γλάστρα μέσα;
• Why are you putting the flowerpot inside?

So the same word does both jobs.

Έξω means outside.

In this sentence:

• έξω φυσάει πολύ
• literally: outside, it blows a lot
• natural English: it’s very windy outside

So έξω tells you where the wind is blowing.

Φυσάει comes from the verb φυσάω / φυσώ, which means to blow (for wind).

So:

• φυσάει = it blows / the wind is blowing

Greek often uses this kind of verb without stating a subject, because the subject is understood from the verb itself or from the situation.

So:

• Έξω φυσάει πολύ
  literally = Outside, it blows a lot
  natural English = It’s very windy outside

You may also see φυσά instead of φυσάει. Both are used.

Greek often does not use a dummy subject like English it.

English says:

• It is raining
• It is windy

Greek usually just says:

• Βρέχει = It’s raining
• Φυσάει = It’s windy / The wind is blowing

So φυσάει works on its own without a separate subject.

Here πολύ means something like a lot or strongly, but in natural English we often translate it as very:

• φυσάει πολύ
  literally = it blows a lot
  natural English = it’s very windy

So πολύ can often correspond to either much/a lot or very, depending on what sounds natural in English.

Yes. Greek word order is more flexible than English, although the original sentence is very natural.

Original:

• Το βράδυ βάζω τη γλάστρα μέσα, γιατί έξω φυσάει πολύ.

You could also hear variations such as:

• Βάζω τη γλάστρα μέσα το βράδυ, γιατί έξω φυσάει πολύ.
• Γιατί έξω φυσάει πολύ, το βράδυ βάζω τη γλάστρα μέσα.

These versions shift the emphasis, but the core meaning stays the same. Greek uses word order more freely to highlight time, reason, or contrast.

Γλάστρα normally means flowerpot / plant pot.

Depending on context, English speakers may sometimes loosely translate it as plant, especially in everyday speech, but the Greek word itself refers to the pot/container, not the plant growing in it.

So in this sentence, the most accurate meaning is:

• τη γλάστρα = the flowerpot / the potted plant (literally, the pot)

A Greek speaker would most likely understand it as a habitual everyday action:

• In the evening, I bring the flowerpot inside because it gets very windy outside.

So the sentence is not just about grammar; it also sounds like a practical routine someone does regularly.
