gōuhuǒ yǐjīng xīmiè le.

已经 means already. It tells you that the action or change has happened before now.

So in this sentence, 已经 highlights that the campfire is already out.

A very common pattern in Chinese is:

已经 + verb + 了

This often corresponds to English already has/have ... or is already ...

The 了 here is a sentence-final particle. In this sentence, it shows a new situation or change of state.

So 熄灭了 does not just mean extinguished in a dictionary sense. In context, it means the campfire has gone out / is now out.

A useful way to feel it is:

• 熄灭 = to go out / be extinguished
• 熄灭了 = has gone out / is now extinguished

With change-of-state sentences, final 了 is very common.

To an English speaker, 已经 and 了 can seem like they both mean already, but they do different jobs.

• 已经 says the action is already completed
• 了 marks the new state or completed change as relevant now

So together they form a very natural pattern:

已经熄灭了 = has already gone out

This pairing is extremely common in Mandarin.

Yes. 篝火熄灭了 is completely natural.

It means the campfire went out or has gone out.

Adding 已经 makes the idea of already more explicit. Without it, the sentence is still fine, but slightly less emphatic about the timing.

Compare:

• 篝火熄灭了。 = The campfire has gone out.
• 篝火已经熄灭了。 = The campfire has already gone out.

Sometimes yes, especially in more formal, written, or report-like contexts. But in everyday speech, 篝火已经熄灭了 sounds more natural.

Why?

Because when you are describing a current changed situation, sentence-final 了 is very common and natural.

So:

• 篝火已经熄灭了。 = very natural in conversation
• 篝火已经熄灭。 = possible, but more formal or clipped

For most learners, using 了 here is the safer choice.

Because 熄灭 is a verb, not a noun phrase or adjective that needs 是.

Chinese does not use 是 the way English uses to be in all sentences.

Here the sentence is built like this:

篝火 + 已经 + 熄灭 + 了
subject + already + verb + particle

So the campfire is the thing undergoing the action/state change of going out.

You would not say:

• 篝火是熄灭了 ❌

That sounds wrong in normal Chinese.

熄灭 is a verb meaning to go out, to be extinguished, or sometimes to extinguish, depending on context.

In this sentence, it is used intransitively, meaning the subject itself undergoes the change:

• 篝火熄灭了。 = The campfire went out.

But in some contexts it can be used transitively too, especially in more formal language:

• 风把蜡烛熄灭了。 = The wind extinguished the candle.

In everyday speech, learners will often also hear simpler verbs like 灭了.

They are close in meaning, but 熄灭 is a bit more formal or literary, and it is especially common for things like:

• flames
• fires
• lights
• candles

灭 is shorter and very common in speech.

Compare:

• 火灭了。 = The fire went out.
• 篝火熄灭了。 = The campfire was extinguished / went out.

In this sentence, 熄灭 sounds slightly more descriptive and polished than plain 灭.

篝火 means campfire or bonfire.

It does not refer to just any fire in general.

For example:

• 火 = fire
• 篝火 = campfire / bonfire

The first character 篝 is not a very common standalone character for beginners. Many learners first meet it in the fixed word 篝火.

So it is best to learn 篝火 as one vocabulary item.

Chinese usually puts adverbs like 已经 before the verb.

So the basic order is:

Subject + adverb + verb + 了

Here:

• 篝火 = subject
• 已经 = adverb
• 熄灭 = verb
• 了 = sentence-final particle

That is why 已经 comes before 熄灭.

A very common Chinese pattern is:

• 他已经回家了。 = He has already gone home.
• 门已经关了。 = The door is already closed / has been shut.
• 篝火已经熄灭了。 = The campfire has already gone out.

Not necessarily.

篝火已经熄灭了 only tells you that the campfire is now out. It does not specify the cause.

It could mean:

• it burned out naturally
• the wind put it out
• someone extinguished it

If you want to say someone did it, Chinese would usually make that explicit, for example:

• 他们已经把篝火熄灭了。 = They have already put out the campfire.

So your original sentence focuses on the resulting state, not the agent.

A natural pronunciation is:

gōuhuǒ yǐjīng xīmiè le

A few points:

• 篝火 = gōuhuǒ
• 已经 = yǐjīng
• 熄灭 = xīmiè
• 了 here is usually neutral tone: le

The last 了 is light and unstressed.

So it sounds roughly like:

gōu-huǒ yǐ-jīng xī-miè le

with the final le said lightly.

Yes, depending on context.

Because 熄灭了 expresses a completed change that results in a current state, it can often be translated in several natural English ways:

• The campfire has gone out.
• The campfire is out.
• The campfire has already been extinguished.

Which English version sounds best depends on context. Chinese often leaves that choice to the translator.

The key idea is: the campfire was burning before, but now it is not.
