Film uzun bir dövüşle bitti.

-le is the suffix meaning with.

So:

• dövüş = fight
• dövüşle = with a fight

In this sentence, uzun bir dövüşle means with a long fight.

This suffix is a shortened form of ile, which also means with. So you could also say:

• Film uzun bir dövüş ile bitti.

But -le / -la attached to the noun is much more common in everyday Turkish.

Because bir is often used when Turkish means a / an in English.

So:

• uzun dövüş = long fight, as a more general or dictionary-like phrase
• uzun bir dövüş = a long fight

In this sentence, the speaker means one particular event at the end of the film, so uzun bir dövüş sounds natural.

Also, with adjectives, Turkish very often uses this pattern:

• adjective + bir + noun

For example:

• güzel bir film = a beautiful film
• zor bir gün = a difficult day
• uzun bir dövüş = a long fight

Because the verb is bitmek = to end / to finish.

Its stem is bit-.
To make the simple past, Turkish adds -di / -dı / -du / -dü (or -ti / -tı / -tu / -tü after certain consonants).

Since bit- ends in the voiceless consonant t, the past ending becomes -ti, not -di:

• bit- + -ti = bitti

So bitti means ended or finished.

This is a normal sound rule in Turkish, not something irregular.

It is the simple past tense.

So bitti means:

• ended
• finished

In this sentence:

• Film uzun bir dövüşle bitti.
• The film ended with a long fight.

The past tense ending here is -ti.

Turkish does not have a direct word for the.

So film can mean:

• film
• the film

You understand whether it is definite or indefinite from the context.

In this sentence, Film naturally means the film because the sentence is talking about a specific film.

Because bir usually means a / an or one.

Compare:

• Film uzun bir dövüşle bitti. = The film ended with a long fight.
• Bir film uzun bir dövüşle bitti. = A film ended with a long fight.

The second version sounds like you are introducing a film for the first time, not talking about a specific one already known from context.

So in your sentence, film is specific, and bir is not needed.

Good question. Turkish distinguishes between:

• bitmek = to end / to come to an end
• bitirmek = to finish something / to bring something to an end

In your sentence, the film itself is ending, so Turkish uses bitmek:

• Film bitti. = The film ended.

But if a person finishes something, Turkish often uses bitirmek:

• Filmi bitirdim. = I finished the film.

So:

• bitti = it ended
• bitirdi = he/she/it finished something

Yes, the word order can change.

The neutral Turkish order is often:

• Subject + other elements + verb

So:

• Film uzun bir dövüşle bitti.

This is a very natural, neutral sentence.

But Turkish word order is flexible, and changing the order can change the emphasis. For example:

• Uzun bir dövüşle film bitti.
  This gives more attention to with a long fight.

• Bitti film uzun bir dövüşle.
  This is much less neutral and may sound literary, dramatic, or context-dependent.

The verb often comes last in normal Turkish prose and speech.

It is in the nominative form, meaning it has no special case ending.

That is the normal form used for the subject of the sentence.

So here:

• Film = the subject
• uzun bir dövüşle = a phrase meaning with a long fight
• bitti = the verb

Because film is the thing that ended, it stays in its basic form.

Yes.

These mean the same thing:

• dövüşle
• dövüş ile

The version with the suffix attached to the noun is usually more natural and more common in everyday Turkish.

So in normal speech, dövüşle is preferred.

Also remember vowel harmony:

• -la / -le

For example:

• arabayla = with the car
• kalemle = with the pen

Here it is dövüşle because the vowel harmony requires -le.

Yes. Dövüş is a noun meaning fight or combat, and it is related to the verb dövüşmek = to fight.

So:

• dövüşmek = to fight
• dövüş = fight

This is common in Turkish: a noun and a verb can be closely related in form.

In this sentence, dövüş is a noun because it is the thing the film ended with.

Because in Turkish, the normal order is:

• adjective + bir + noun

So:

• uzun bir dövüş
• güzel bir ev
• eski bir kitap

Putting bir before the adjective is not the normal pattern in standard Turkish for this kind of phrase.

So uzun bir dövüş is the correct natural form.

Yes, depending on context.

For example:

• Film bitti. = The film ended.
• Ders bitti. = The class is over / ended.
• Toplantı bitti. = The meeting is over / ended.

So in your sentence, bitti means the film came to its end, and English may translate that as ended or sometimes was over, depending on style.

Yes, it is grammatical and natural.

It sounds like a normal way to say that the movie’s ending involved a long fight scene.

A native speaker might also say something like:

• Film uzun bir dövüş sahnesiyle bitti. = The film ended with a long fight scene.

That version is a little more specific, because dövüş just means fight, while dövüş sahnesi means fight scene. But your original sentence is still perfectly fine.
