Rüzgâr artınca, ben balkondan içeri giriyorum.

Artınca comes from artmak, which means to increase, to rise, or for things like wind, to get stronger / pick up.

It is built like this:

• art- = verb stem
• -ınca = a suffix meaning when / once / as soon as

So rüzgâr artınca means when the wind gets stronger or when the wind picks up.

This suffix changes by vowel harmony, so you may also see:

• -ınca
• -ince
• -unca
• -ünce

Its core meaning is when / once / as soon as.

In a sentence like this, English may feel a bit causal, because the second action happens as a reaction to the first. So the overall idea is:

• When the wind picks up, I go inside
• and by implication, because the wind picked up, I go inside

But grammatically, -ınca is mainly a time-linking suffix, not a direct because marker.

Yes, ben is often optional in Turkish.

The verb giriyorum already tells you the subject is I, because -yorum marks first person singular. So Turkish could simply say:

Rüzgâr artınca, balkondan içeri giriyorum.

Adding ben can give:

• extra emphasis
• contrast
• clarity

For example, it can feel like:

• As for me, I go inside
• I go inside when the wind picks up

So ben is not wrong at all, but it is not strictly necessary.

Because -dan / -den marks movement from a place.

So:

• balkon = balcony
• balkondan = from the balcony

That fits the meaning here: the speaker is moving away from the balcony and going inside.

Compare:

• balkona = to the balcony
• balkonda = on the balcony / at the balcony
• balkondan = from the balcony

So balkondan içeri giriyorum means something like I go inside from the balcony.

İçeri means inside / indoors / in.

In this sentence, it works with girmek to express motion inward:

• içeri girmek = to go in / to go inside / to enter

So the phrase: balkondan içeri giriyorum means:

• I go inside from the balcony
• I head indoors from the balcony

It is very natural Turkish.

All of these are related, but they are not used in exactly the same way.

• içeri = inside / indoors
• içeriye = a more explicitly directional form, roughly to the inside
• içine = into its interior / into the inside of something

With girmek, Turkish very often uses plain içeri:

• içeri girmek = go inside

You can also hear içeriye girmek, but içeri girmek is simpler and very common.

İçine would usually need a more specific container or place:

• odanın içine girdim = I went into the room
• kutunun içine koydum = I put it into the box

So in your sentence, içeri is the most natural everyday choice.

Giriyorum is the present continuous form of girmek:

• girmek = to enter / go in
• giriyorum = I am entering / I am going in

But Turkish -iyor is broader than English am ... -ing. It can describe:

• something happening right now
• something happening around this time
• a regular or repeated action in a vivid, natural way

So here it can mean either:

• I’m going inside when the wind picks up
• I go inside when the wind picks up

Both are possible depending on context.

Yes, it could, but the feeling changes a little.

• giriyorum sounds more immediate, vivid, or scene-based
• girerim sounds more like a general habit or rule

So:

• Rüzgâr artınca, balkondan içeri giriyorum
  = natural for describing what happens in a situation, possibly even a repeated one

• Rüzgâr artınca, balkondan içeri girerim
  = more like When the wind picks up, I usually go inside

Both can work, but giriyorum is very natural in everyday speech.

It can correspond to either in English.

Turkish girmek means to enter / go in / come in, but it does not force the same go/come distinction that English often does. The exact translation depends on viewpoint and context.

So içeri giriyorum could be translated as:

• I’m going inside
• I’m coming in
• I’m entering

English chooses between those based on perspective. Turkish usually just uses girmek.

No, Turkish word order is fairly flexible, although the verb usually comes at the end.

Your sentence starts with the time clause: Rüzgâr artınca, ben balkondan içeri giriyorum.

That is very natural. But other orders are also possible, for example:

• Ben rüzgâr artınca balkondan içeri giriyorum.
• Rüzgâr artınca balkondan içeri giriyorum.

Putting rüzgâr artınca first is common because it sets the scene: when the wind picks up...

Yes, you could say rüzgâr arttığında, and it would still mean when the wind increases / gets stronger.

But there is a slight difference in feel:

• artınca often sounds more immediate, like when / once it picks up
• arttığında can sound a bit more neutral or formal, like when it has increased / when it is stronger

In everyday speech, artınca is very natural in this kind of trigger-response sentence.

Rüzgâr is pronounced approximately like rüz-gaar, with:

• ü as the front rounded vowel in Turkish
• a somewhat lengthened a

The circumflex in â can signal things like:

• vowel length
• a historical sound difference
• sometimes a subtle pronunciation distinction

In modern writing, some people also write rüzgar without the circumflex, but rüzgâr is the more careful spelling.
