Restoran beşinci katta.

In Turkish, the verb to be is often not stated in simple present-tense sentences like this one.

So:

• Restoran beşinci katta = The restaurant is on the fifth floor

Turkish commonly leaves out is / are in sentences of this type, especially in the third person.

Compare:

• Ben yorgunum = I am tired
• O yorgun = He/she is tired

In the third person, Turkish often has zero copula, meaning there is no separate word for is.

Beşinci katta means on the fifth floor.

It breaks down like this:

• beş = five
• beşinci = fifth
• kat = floor/storey
• katta = on the floor / on the storey

So:

• beşinci kat = fifth floor
• beşinci katta = on the fifth floor

In the full sentence:

• Restoran beşinci katta = The restaurant is on the fifth floor

Because English fifth is an ordinal number, not a basic counting number.

Turkish works the same way:

• bir = one → birinci = first
• iki = two → ikinci = second
• üç = three → üçüncü = third
• beş = five → beşinci = fifth

So if you want to say fifth floor, you need beşinci kat, not beş kat.

• beş kat would mean something like five floors or five storeys, depending on context.
• beşinci kat means the fifth floor.

Because Turkish uses the locative suffix to mean in / on / at, and that suffix changes shape depending on the sound before it.

The basic locative suffix is:

• -de / -da / -te / -ta

Here the word is kat. Since kat ends in the voiceless consonant t, the suffix becomes -ta, not -da.

So:

• kat + ta → katta

This is due to consonant harmony in Turkish.

A few examples:

• evde = at home
• okulda = at school
• parkta = in the park
• katta = on the floor

The double tt is just what happens when the word already ends in t and the suffix also begins with t.

The ending -ta is the locative case suffix. It tells you the location: in, on, at.

In this sentence:

• kat = floor
• katta = on the floor

So beşinci katta literally means at the fifth floor, but natural English is on the fifth floor.

Turkish uses this suffix very often for places:

• evde = at home
• işte = at work
• masada = on the table
• odada = in the room

Turkish does not have a word exactly like English the.

So:

• Restoran can mean restaurant or the restaurant, depending on context.
• beşinci katta can mean on the fifth floor, even though there is no separate word for the.

Turkish relies heavily on context rather than articles.

It also does not use a/an in the same way English does. So learners often need to get used to the fact that Turkish nouns often appear without any article at all.

Yes, but Turkish word order is also somewhat flexible.

The neutral, natural order here is:

• Restoran beşinci katta

This is:

• Restoran = topic/subject
• beşinci katta = location

So it means The restaurant is on the fifth floor.

You may also hear different orders for emphasis, such as:

• Beşinci katta restoran
• Beşinci katta restoran var

But the given sentence is the most straightforward way to say it.

In simple terms, Turkish often puts the most important new information near the end, and here the location beşinci katta comes last.

A rough pronunciation is:

• beh-shin-jee

More carefully:

• beş sounds like besh
• i is like the i in sit
• nc in -inci sounds like nj in pronunciation
• final i again is a short i sound

So beşinci is approximately:

• besh-in-jee
• or more accurately beh-shin-jee

The letter ş is pronounced like sh in shoe.

A rough pronunciation is:

• kaht-tah

Notes:

• a is a clear ah sound
• the double tt is pronounced distinctly, with a stronger t sound than in English
• final a is again ah

So:

• katta ≈ kaht-tah

Turkish pronunciation is usually quite regular, so once you know the letters, spelling and pronunciation match closely.

Kat is just the noun:

• kat = floor / storey

Katta is that noun with the locative ending:

• katta = on the floor / on a floor

So:

• beşinci kat = the fifth floor
• beşinci katta = on the fifth floor

This is a very common pattern in Turkish:

• oda = room

• odada = in the room

• masa = table

• masada = on the table

• kat = floor
• katta = on the floor

Yes, in a literal sense kat means floor or storey, so it refers to the level of a building.

In natural English, though, the best translation is:

• The restaurant is on the fifth floor

That is how English normally says it.

So while storey is not wrong in a dictionary sense, floor is what you would usually say in normal conversation.

Because it is just the subject/topic of the sentence in its basic form.

Turkish often uses the bare noun when the noun is the subject of a simple sentence.

So:

• Restoran = the restaurant
• Restoran beşinci katta = The restaurant is on the fifth floor

There is no need for an extra ending here.

If the noun had another role in the sentence, it might take a case ending, but as the subject/topic in this sentence, the plain form is normal.

Yes. Restoran beşinci kattadır is grammatical.

The ending -dır / -dir / -dur / -dür can add a slightly more formal, definite, or explanatory tone.

So:

• Restoran beşinci katta = normal everyday speech
• Restoran beşinci kattadır = more formal or emphatic

In ordinary conversation, the shorter version without -dır is much more common.
