Parkta yürüyüş yapınca temiz hava beni tazeliyor.

Parkta is park + -ta, the locative case, which means in/at the park.

• park = park
• parkta = in the park / at the park

The ending changes form depending on vowel harmony and consonants:

• evde = at home
• okulda = at school
• parkta = in the park

Here it tells you where the walking happens.

Turkish often uses a noun + yapmak structure where English might use a simple verb.

• yürümek = to walk
• yürüyüş yapmak = to take a walk / to go for a walk / to do walking

So parkta yürüyüş yapınca has the sense of when I take a walk in the park.

Using yürümek would also be possible in some contexts, but yürüyüş yapmak is a very common and natural expression for going on a walk, especially as an activity.

The ending -ınca / -ince / -unca / -ünce usually means when, once, or sometimes whenever.

So:

• yapmak = to do
• yapınca = when doing / when one does / once one does

In this sentence, parkta yürüyüş yapınca means something like:

• when I take a walk in the park
• when I go for a walk in the park
• possibly whenever I take a walk in the park, depending on context

This form often gives a general condition or repeated situation, especially with a present-tense main clause like tazeliyor.

In Turkish, the subject is often understood from context and does not have to be stated.

So parkta yürüyüş yapınca literally does not say when I walk or when you walk explicitly. The listener figures it out from the sentence context.

In this sentence, because of beni (me) and the overall meaning, the understood subject is naturally I:

• when I take a walk in the park, the fresh air refreshes me

Turkish often leaves subjects unstated when they are already clear.

Because temiz hava is the thing doing the action of refreshing.

• temiz = clean / fresh
• hava = air
• temiz hava = fresh air

In temiz hava beni tazeliyor:

• temiz hava = subject
• beni = object (me)
• tazeliyor = is refreshing / refreshes

So literally: fresh air refreshes me.

Beni is ben + -i.

• ben = I
• beni = me

The ending -i marks the definite direct object. Since tazelemek acts on something, Turkish marks the object:

• temiz hava beni tazeliyor = the fresh air refreshes me

You can think of beni as the object receiving the action.

The verb is tazelemek, meaning to refresh or to make fresh.

To form the present continuous:

• remove -mek
• add -iyor (with vowel harmony effects)

So:

• tazelemek
• stem: tazele-
• present continuous: tazeliyor

This is a normal sound pattern in Turkish verb conjugation. The form may look slightly compressed, but it comes directly from the verb stem plus the -iyor tense marker.

Tazeliyor is in the present continuous form: -iyor.

Depending on context, Turkish present continuous can mean:

• is refreshing me right now
• refreshes me generally
• keeps refreshing me

In this sentence, it most naturally has a general/habitual meaning:

• When I take a walk in the park, the fresh air refreshes me.

So even though the form is technically present continuous, English often translates it with the simple present in sentences like this.

Yes. That is one of the natural interpretations.

Because -ınca plus a present-tense main clause often describes a repeated, general result, the sentence can mean:

• When I take a walk in the park, the fresh air refreshes me
• Whenever I take a walk in the park, the fresh air refreshes me

Turkish often leaves that distinction to context instead of marking it very explicitly.

Turkish word order is flexible, but the neutral pattern is often Subject–Object–Verb, and time/place expressions often come earlier.

Here we have:

• Parkta = in the park
• yürüyüş yapınca = when taking a walk
• temiz hava = fresh air
• beni = me
• tazeliyor = refreshes

So the verb comes at the end, which is very typical in Turkish.

A more literal order would be:

• In the park, when taking a walk, fresh air me refreshes.

That sounds strange in English, but it is normal in Turkish.

Literally, temiz hava is clean air, but in natural English this is often best understood as fresh air.

So although temiz basically means clean, in this context the phrase refers to the pleasant, healthy outdoor air you breathe while walking in a park.

Yes, you could say something like Parkta yürüyünce temiz hava beni tazeliyor.

That would mean:

• When I walk in the park, the fresh air refreshes me.

The difference is mostly one of expression:

• yürümek = to walk
• yürüyüş yapmak = to go for a walk / take a walk

Yürüyüş yapmak can sound a bit more like a deliberate activity or exercise, while yürümek is the simpler verb to walk. Both can work.

Yes, that is close to the literal structure.

• tazelemek = to refresh / make fresh / revive

So beni tazeliyor is literally something like:

• it is refreshing me
• it makes me feel refreshed

In natural English, refreshes me is the best translation. It can refer to feeling more energetic, revived, or mentally renewed.
