Τον Ιανουάριο κάνει πολύ κρύο εδώ, γι’ αυτό φοράω παλτό το πρωί.

Because τον Ιανουάριο is in the accusative case, and Greek often uses the accusative for time expressions.

So:

• ο Ιανουάριος = January
• τον Ιανουάριο = in January / during January

This is very common:

• τον Μάιο = in May
• την Κυριακή = on Sunday
• το βράδυ = at night / in the evening

So here τον Ιανουάριο means in January.

Greek often uses the verb κάνω in weather expressions.

So:

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

Literally, κάνει κρύο is something like it makes cold, but you should learn it as the normal Greek way to say it is cold.

This is an impersonal expression, so there is no word for it.

Πολύ means very here.

So:

• κρύο = cold
• πολύ κρύο = very cold

In this sentence:

• κάνει πολύ κρύο = it is very cold

Be careful: πολύ can also mean much / a lot, depending on the context.

Εδώ means here.

Greek word order is more flexible than English, so εδώ can move around more easily. In this sentence:

• κάνει πολύ κρύο εδώ = it is very cold here

This sounds natural. You could also hear:

• εδώ κάνει πολύ κρύο

That would put a little more emphasis on here.

Γι’ αυτό means for that reason, that’s why, or so.

In this sentence:

• Τον Ιανουάριο κάνει πολύ κρύο εδώ, γι’ αυτό φοράω παλτό το πρωί.
• In January it is very cold here, so / that’s why I wear a coat in the morning.

It connects the two ideas:

1. It is very cold.
2. Because of that, I wear a coat.

Because it is a shortened form of για αυτό.

So:

• για αυτό → γι’ αυτό

This shortening is very common in everyday Greek.

You should also notice that γι’ αυτό means for that / that’s why, and it is different from γιατί, which means why or because depending on the sentence.

Φοράω means I wear.

So:

• φοράω παλτό = I wear a coat

This verb is used for clothes, shoes, glasses, perfume, and similar things that you have on your body.

Examples:

• φοράω παπούτσια = I wear shoes
• φοράει γυαλιά = he/she wears glasses

A learner may confuse this with βάζω, which often means put on. Very roughly:

• βάζω παλτό = I put on a coat
• φοράω παλτό = I am wearing / I wear a coat

Greek often leaves out the indefinite article when English would use a.

So:

• φοράω παλτό = I wear a coat / I wear coats / I wear a coat as a general thing

If you say:

• φοράω ένα παλτό

that means more specifically I am wearing one coat or a coat with a little more focus on the item.

So the version without ένα sounds very natural for a general statement.

Παλτό means coat and it is a neuter noun.

Its article is:

• το παλτό = the coat

It is also a word that does not change much in form, so it looks the same in nominative and accusative:

• το παλτό
• φοράω παλτό

That is why it may seem simpler than some other Greek nouns.

Το πρωί is a fixed time expression meaning in the morning.

Greek very often uses the article in expressions like this:

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

So even though English says in the morning, Greek simply says the morning in this kind of phrase.

It can suggest either, depending on context, but here it is best understood as a habitual present:

• φοράω παλτό το πρωί = I wear a coat in the morning

Because the sentence talks about January in general, the idea is probably habitual: this is what I usually do in the mornings when it is cold.

Greek present tense often covers both:

• I wear
• I am wearing

The context tells you which one is meant.

Because γι’ αυτό introduces the result of the first clause.

The sentence has two parts:

1. Τον Ιανουάριο κάνει πολύ κρύο εδώ
2. γι’ αυτό φοράω παλτό το πρωί

The comma helps separate the cause from the result, just like English often does with so or that’s why.

By itself, τον Ιανουάριο usually means in January. The exact meaning depends on context.

It can mean:

• this January
• in January as a general time reference
• sometimes even every January, if the context is habitual

In this sentence, because of the general present tense κάνει and φοράω, it most naturally sounds like a general statement about what January is like there.

In κάνει κρύο, κρύο behaves like a noun meaning cold.

So the structure is more like:

• it makes cold

rather than:

• it is cold

But for learning purposes, it is best to memorize κάνει κρύο as a complete weather expression meaning it is cold.

This is why you do not see a form that directly matches the English adjective cold here.
