Kahve altı lira.

Because Turkish often leaves out the verb to be in simple present-tense noun sentences.

So where English says:

• The coffee is six lira

Turkish can simply say:

• Kahve altı lira

This is a very common pattern. In the present tense, when one noun phrase is being equated with another noun phrase, adjective, or price, Turkish usually uses a zero copula—in other words, no separate word for is appears.

Compare:

• Hava güzel. = The weather is nice.
• Ben öğretmenim. = I am a teacher.
  (Here the personal ending appears because the subject is I.)
• Kahve altı lira. = The coffee is six lira.

So the sentence is completely normal and complete even without a visible verb.

It is a full, normal Turkish sentence.

It may feel shortened to an English speaker because English usually requires is or costs, but Turkish does not need that here.

This kind of sentence is called a nominal sentence: the predicate is a noun phrase rather than a regular verb phrase.

Here:

• Kahve = the coffee / coffee
• altı lira = six lira

So structurally it is something like:

• Coffee — six lira.

But in Turkish, that is a complete sentence in the present tense.

Because Turkish has no direct equivalent of English articles a/an and the.

That means kahve can mean:

• coffee
• the coffee
• sometimes even a coffee

The exact sense depends on context.

In a situation like a menu, café, or shop, Kahve altı lira would usually be understood as something like:

• Coffee is six lira
• The coffee costs six lira
• A coffee is six lira

Turkish relies much more on context than English does for this.

Because after numbers, Turkish nouns normally stay singular.

So:

• bir lira = one lira
• iki lira = two lira
• altı lira = six lira

Not:

• altı liralar ✗

This is a very important Turkish rule:

• üç kitap = three books
• beş öğrenci = five students
• on gün = ten days

Even though English uses plural nouns after numbers, Turkish usually does not.

Yes, Kahve altı liradır is possible.

The ending -dır / -dir / -dur / -dür is a copular ending that can make the sentence sound:

• more formal
• more definite
• more explanatory
• sometimes more like a general statement

So:

• Kahve altı lira. = neutral, everyday
• Kahve altı liradır. = more formal or assertive

In normal conversation, the shorter version without -dır is very common.

Yes. Turkish can also express this idea with a verb, but in everyday usage the noun-sentence pattern is very common for prices.

For example, you may also hear:

• Kahve altı lira tutuyor.
• Kahve altı lira ediyor.

But these are less basic and less neutral than the simple price statement:

• Kahve altı lira.

For a beginner, it is best to learn that Turkish often states prices with this simple structure:
[item] + [price]

Examples:

• Su iki lira.
• Ekmek on lira.
• Bilet yüz lira.

Kahve altı lira is the most straightforward and natural order in a simple statement like this.

Turkish word order is flexible, but different orders can sound marked, contrastive, or context-dependent.

The basic idea here is:

• Kahve = topic/thing being talked about
• altı lira = what is being said about it

So Kahve altı lira is the most natural default form.

A different order might be possible in special contexts, but for learners, this is the version to use.

Because kahve is the subject/topic of the sentence in its basic dictionary form.

There is no reason here to add accusative, dative, locative, etc.

You are not saying:

• to the coffee
• the coffee as a direct object
• in the coffee

You are simply identifying the price of coffee.

So the plain form is used:

• kahve

If the sentence had a different structure, a case ending might appear, but not in this one.

The ı is the Turkish dotless i, and it is one of the sounds English speakers often need to practice.

It is:

• not like English ee
• not like the i in sit
• pronounced farther back in the mouth

A rough approximation is the vowel sound in the second syllable of roses for some English speakers, but that is not exact.

So:

• altı sounds roughly like ahl-tuh with a special back vowel at the end
• lira has normal dotted i, so that first vowel is different from the last vowel in altı

This is important because Turkish clearly distinguishes:

• i = dotted i
• ı = dotless i

They are different vowels and different letters.

Mostly yes, but there are two useful things to notice:

• kahve is pronounced roughly kah-veh
• the h is pronounced
• the final e is pronounced, not silent

So it is not like English café, and the final vowel does not disappear.

Also, Turkish pronunciation is generally very regular, so once you learn the sound of each letter, words are usually pronounced as written.

Often, lira by itself is enough, especially in modern Turkish context.

But if you want to be more explicit, you can say:

• Kahve altı Türk lirası.

This means The coffee is six Turkish lira.

Notice that with a more specific currency phrase like Türk lirası, Turkish commonly uses that full expression. But in everyday situations inside Turkey, just lira is usually perfectly clear.
