Artikülasyon çok seslilikte önemli.

Because Turkish often leaves out the verb to be in the present tense, 3rd person.

So önemli does the job of is important here.

A very literal structure is:

• Artikülasyon = articulation
• çok seslilikte = in polyphony / in a polyphonic context
• önemli = important

So the full sense is Articulation is important in polyphony.

If you wanted to make the copula visible in another tense, Turkish would show it more clearly, for example:

• Artikülasyon çok seslilikte önemliydi = Articulation was important in polyphony

Çok seslilikte is built in layers:

• çok = many / much
• sesli = voiced / having sound(s)
• çok sesli = polyphonic / multi-voiced
• çok seslilik = polyphony / multivoicedness
• çok seslilikte = in polyphony / in polyphonic writing or texture

The ending -te is the locative case, which often means in, at, on, within.

So çok seslilikte means something like:

• in polyphony
• in a polyphonic context
• when it comes to polyphonic music

This is because of consonant harmony in Turkish.

The locative ending has four common forms:

• -da
• -de
• -ta
• -te

The choice depends on:

1. vowel harmony
2. whether the last consonant is voiced or voiceless

In çok seslilik, the final consonant is k, which is voiceless, so the suffix uses t rather than d.

Also, the last vowel is a front vowel, so the vowel in the suffix becomes e.

So:

• çok seslilik + de becomes çok seslilikte

Because Turkish usually places the predicate at the end.

In this sentence, önemli is the predicate, so it naturally comes last.

That gives this basic order:

• Artikülasyon = subject/topic
• çok seslilikte = context/location
• önemli = predicate

This is very natural Turkish word order.

Yes. In this sentence, Artikülasyon is the thing being talked about, so it functions as the subject.

The sentence is essentially saying:

• Articulation → is important → in polyphony

So the grammatical core is:

• Artikülasyon önemli = Articulation is important

And çok seslilikte adds the setting or field where that is true.

Turkish does not have articles like English the and a/an.

So Artikülasyon can mean:

• articulation
• the articulation

The exact meaning depends on context.

In general statements like this, English often uses no article too:

• Articulation is important in polyphony

So the Turkish sentence sounds very natural without any article-like word.

Not necessarily. The locative case in Turkish does often mean physical location, but it can also mean within a field, area, topic, situation, or context.

So here çok seslilikte does not mean a physical place. It means:

• in polyphony
• in the context of polyphony
• when dealing with polyphonic music

This kind of abstract use of the locative is very common in Turkish.

Yes, that is also possible.

Both are grammatical, but the emphasis changes slightly.

• Artikülasyon çok seslilikte önemli puts articulation first, so it sounds like the main topic.
• Çok seslilikte artikülasyon önemli puts in polyphony first, so it highlights the context first.

So the difference is mostly about focus and information flow, not basic meaning.

Because the sentence is not saying in something polyphonic as an adjective. It is using the noun çok seslilik, which means polyphony.

Compare:

• çok sesli = polyphonic / multi-voiced → adjective
• çok seslilik = polyphony → noun

The locative suffix is attached to the noun form:

• çok seslilikte = in polyphony

So the sentence needs the noun idea polyphony, not just the adjective polyphonic.

Because the base expression is çok sesli, which is normally written as two words in Turkish.

Then the noun-forming ending -lik is added to the second part:

• çok sesli → çok seslilik

And the case ending is added after that:

• çok seslilik → çok seslilikte

So only the final word in the expression carries the suffixes.

This is normal in Turkish for many multi-word expressions.

Its main meaning is important, but depending on context it can also feel like:

• significant
• of importance
• noteworthy

In this sentence, important is the most straightforward and natural meaning.

It is a loanword, used in Turkish especially in technical, musical, linguistic, or phonetic contexts.

That is very normal in Turkish. Many academic or musical terms are borrowed but fully usable in Turkish grammar.

So even though artikülasyon is not originally Turkic, it behaves like a normal Turkish noun in the sentence.

You could say:

Artikülasyon çok seslilikte çok önemli.

Here the first çok belongs to seslilik and helps form çok seslilik = polyphony, while the second çok means very.

So:

• çok seslilik = polyphony
• çok önemli = very important

Turkish often allows the same word to appear twice with different functions like this.
