Ateş yakma yasağı açıklanmakla kalmayıp hemen uygulandı.

It is a noun phrase meaning the ban on lighting fires.

Breakdown:

• ateş = fire
• yakma = lighting / burning
  This comes from yakmak (to burn / to light), but here it is turned into a verbal noun.
• yasağı = its ban / the ban

So:

• ateş yakma = lighting a fire
• ateş yakma yasağı = the ban on lighting fires

A very similar pattern is:

• sigara içme yasağı = smoking ban

Because this is a Turkish noun compound.

In compounds like this, the second noun usually takes the 3rd person possessive suffix:

• yasak → yasağı

So ateş yakma yasağı is not random inflection; it is the normal compound pattern.

Also, the final k in yasak changes to ğ before a vowel:

• yasak
  • -ı → yasağı

This is a very common sound change in Turkish.

No. Here it is not the accusative.

It is the compound/possessive ending that appears on the second noun in an indefinite noun compound.

That matters because ateş yakma yasağı is actually the subject of the sentence, not the direct object.

So:

• not: the ban as an accusative object
• yes: the ban as the subject, with the normal compound ending

This is a very common point of confusion because the form can look similar to the accusative.

It comes from a verb, but here it functions more like a verbal noun.

• yakmak = to burn / to light
• yakma = burning / lighting

So in this sentence, yakma does not mean burn! as a command. It is the noun-like form lighting/burning.

In ateş yakma yasağı, it helps create the idea ban on lighting fires.

As a whole, it means something like:

• not only being announced, but also...
• not merely being announced, and instead also...

This is a common Turkish structure:

• -makla kalmayıp
• -mekle kalmayıp

It often corresponds to English not only ... but also ...

So here:

• açıklanmakla kalmayıp hemen uygulandı = it was not only announced, but was also immediately enforced/applied

This structure is fairly formal and common in written Turkish.

It has several pieces:

• açıklanmak = to be announced / to be explained
  (açıklamak is active: to explain / announce; açıklanmak is passive: to be explained / announced)
• -la in -makla = part of the expression used in this pattern
• kalmayıp / kalmayıp = not remaining with / not stopping at

So the idea is literally close to:

• not stopping at being announced

In smoother English, that becomes:

• not only being announced
• not merely being announced

Then the sentence continues with what happened in addition:

• hemen uygulandı = it was immediately enforced/applied

Because the ban is something that is announced by someone.

• açıklamak = to announce / explain
• açıklanmak = to be announced / to be explained

The sentence focuses on the ban itself, not on who announced it. That is why the passive fits naturally.

English does the same thing here:

• The ban was announced
• rather than
• Someone announced the ban

For the same reason: the sentence focuses on the ban, not on the authorities or people carrying out the action.

• uygulamak = to apply / implement / enforce
• uygulanmak = to be applied / implemented / enforced
• uygulandı = it was applied / implemented / enforced

So the sentence keeps the same perspective throughout:

• the ban was announced
• the ban was enforced

This gives the sentence a formal, impersonal tone, which is very common in official or news-like Turkish.

All three are possible depending on context.

Literally, uygulandı is was applied / was implemented.
But with a ban, English often prefers was enforced.

So in this sentence, the most natural English idea is probably:

• The ban was not only announced, but immediately enforced.

If you translate very literally, implemented also works.

Hemen means immediately / right away.

It tells you that the second action happened without delay:

• the ban was announced
• and it was immediately put into effect

So hemen strengthens the contrast: it was not just a verbal announcement; action followed at once.

Because Turkish normally puts the main finite verb near or at the end.

So the sentence builds up the information first, and the final verb completes it:

• Ateş yakma yasağı = the ban on lighting fires
• açıklanmakla kalmayıp = not only being announced
• hemen uygulandı = was immediately enforced

This end position for the verb is one of the most basic word-order patterns in Turkish.

Yes. Very much so.

Even though yakmak often means to burn, the phrase ateş yakmak commonly means:

• to light a fire
• to make a fire

So ateş yakma yasağı is best understood as:

• ban on lighting fires
• ban on making fires

not as something strange like fire-burning ban.

Yes, it is somewhat formal and especially common in writing, news, official language, and careful speech.

A more conversational way to express the same idea might be something like:

• Sadece açıklanmadı, hemen de uygulandı.
• It wasn’t just announced; it was enforced immediately too.

But -makla kalmayıp is very natural in formal Turkish and is worth learning because you will see it often.
