Το βράδυ βάζω το πάπλωμα στο κρεβάτι γιατί κάνει κρύο.

In this sentence, το βράδυ is being used as a time expression. Greek often uses the article + noun this way to mean during that time.

So:

• το βράδυ = in the evening / at night
• literally, it is the evening, but functionally it means during the evening

This is very common in Greek:

• το πρωί = in the morning
• το μεσημέρι = at noon / midday
• το απόγευμα = in the afternoon
• τη νύχτα = at night

So here Το βράδυ βάζω... means In the evening, I put...

βάζω is the 1st person singular present tense of the verb βάζω, meaning I put, I place, or sometimes I set.

Here it means:

• βάζω = I put

So:

• Το βράδυ βάζω το πάπλωμα... = In the evening I put the duvet...

The present tense in Greek can also describe a habitual action, not only something happening right now. So this sentence can mean:

• I put the duvet on the bed in the evening
• or In the evening, I usually put the duvet on the bed

το is the definite article for a neuter singular noun.

• πάπλωμα = duvet / quilt
• το πάπλωμα = the duvet / the quilt

Greek uses definite articles more regularly than English, so seeing το here is completely normal.

Also, το πάπλωμα is the direct object of βάζω:

• I put what? → the duvet

That is why it appears in the accusative, but for many neuter nouns like πάπλωμα, the nominative and accusative forms are the same:

• nominative: το πάπλωμα
• accusative: το πάπλωμα

Not exactly.

• πάπλωμα usually means duvet, quilt, or a thick bed covering
• κουβέρτα means blanket

So το πάπλωμα suggests the thicker bedding you put on the bed when it is cold.

That fits well with the second part of the sentence:

• γιατί κάνει κρύο = because it’s cold

στο is the contracted form of:

• σε + το = στο

This contraction is standard and extremely common in modern Greek.

So:

• στο κρεβάτι = on the bed / in the bed / onto the bed, depending on context

The full form σε το κρεβάτι is generally not used in normal modern Greek.

Similar contractions:

• σε + την = στην
• σε + τον = στον
• σε + τα = στα

After σε (and therefore after στο), Greek normally uses the accusative in modern everyday language.

So in:

• στο κρεβάτι

the noun κρεβάτι is in the accusative singular.

Because κρεβάτι is a neuter noun, the nominative and accusative look the same:

• nominative: το κρεβάτι
• accusative: το κρεβάτι

That is why the form does not visibly change.

In this sentence, the most natural meaning is on the bed or onto the bed.

Because the verb is βάζω = I put, there is an idea of placing something somewhere. So:

• βάζω το πάπλωμα στο κρεβάτι = I put the duvet on the bed

Greek σε / στο can cover several English prepositions depending on context, including in, on, and to/into/onto.

So the exact English choice depends on the situation, but here on the bed is the best natural translation.

This is a very common Greek weather expression.

Literally:

• κάνει = it does / it makes
• κρύο = cold

But together κάνει κρύο means:

• it is cold
• the weather is cold

This is an impersonal expression, just like some weather expressions in English.

Other similar Greek examples:

• κάνει ζέστη = it’s hot
• κάνει καλό καιρό = the weather is nice
• κάνει φασαρία = it’s noisy / there is noise

So you should learn κάνει κρύο as a set phrase.

Because Greek often uses impersonal verbs/expressions without an explicit subject pronoun.

In English, we need it in weather expressions:

• it’s cold
• it’s raining

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

So:

• κάνει κρύο = it’s cold
• not αυτό κάνει κρύο

Adding αυτό here would sound unnatural.

γιατί means because here. It introduces the reason:

• βάζω το πάπλωμα στο κρεβάτι = I put the duvet on the bed
• γιατί κάνει κρύο = because it’s cold

So the full structure is:

• main clause + γιατί + reason

Be aware that γιατί can also mean why in questions:

• Γιατί; = Why?
• ...γιατί κάνει κρύο. = ...because it’s cold.

Same word, different function depending on context.

No, Greek word order is fairly flexible, although some orders sound more natural than others.

The given sentence:

• Το βράδυ βάζω το πάπλωμα στο κρεβάτι γιατί κάνει κρύο.

is natural and neutral.

But Greek could also say things like:

• Βάζω το πάπλωμα στο κρεβάτι το βράδυ γιατί κάνει κρύο.
• Γιατί κάνει κρύο, το βράδυ βάζω το πάπλωμα στο κρεβάτι.

The basic meaning stays the same, but the focus or emphasis can change.

Placing Το βράδυ at the start highlights the time frame: In the evening...

It can mean either, depending on context. In this sentence, the most natural reading is habitual:

• In the evening, I put the duvet on the bed because it’s cold
• or I put the duvet on the bed in the evening because it’s cold

Greek present tense often covers both:

• an action happening now
• a regular or repeated action

Because of Το βράδυ and the general statement about the cold, this sounds more like a routine than something happening at this exact moment.

They are related, but not exactly the same.

• το βράδυ = in the evening / at night in a broad everyday sense
• τη νύχτα = at night / during the night, often later and darker

So το βράδυ usually refers to the evening period, while τη νύχτα refers more specifically to nighttime.

In this sentence, Το βράδυ sounds very natural if the idea is a daily evening routine, like preparing the bed when it gets cold.

A simple breakdown is:

• Το βράδυ = time expression (in the evening)
• βάζω = verb (I put)
• το πάπλωμα = direct object (the duvet)
• στο κρεβάτι = place/destination phrase (on the bed)
• γιατί κάνει κρύο = reason clause (because it’s cold)

So the sentence structure is basically:

• Time + Verb + Object + Place + Reason

That is a very common and useful pattern in Greek.
