Kitap altmış sayfa.

In Turkish, present-tense to be is often not said explicitly in simple sentences like this.

So:

• Kitap altmış sayfa. = The book is sixty pages.

This is very normal Turkish. The idea of is is understood automatically.

If you want, you can also use a more formal or emphatic form:

• Kitap altmış sayfadır.

That -dır adds the sense of is more overtly, but in everyday speech it is often omitted.

Because in Turkish, nouns after numbers are usually singular, not plural.

So Turkish says:

• bir sayfa = one page
• iki sayfa = two pages
• altmış sayfa = sixty pages

A native English speaker often expects a plural noun after numbers greater than one, but Turkish does not usually do that.

So altmış sayfalar would sound wrong here.

It can mean either, depending on context.

Turkish has no word like English articles a/an and the in many basic sentences. So:

• Kitap altmış sayfa.

can mean:

• The book is sixty pages.
• A book is sixty pages.
• This book is sixty pages.
  depending on the situation

In real use, context tells you which meaning is intended. Very often, in a sentence like this, learners will see it translated as The book is sixty pages because that sounds most natural in context.

It is a predicate expression describing the book.

Literally, it is sixty page, but naturally it means:

• sixty pages long
• sixty pages in length
• sixty pages total

Turkish often uses this kind of noun phrase directly, without needing an extra word like long.

So instead of saying something equivalent to The book is sixty pages long, Turkish can simply say:

• Kitap altmış sayfa.

Yes. That is correct.

• Kitap altmış sayfa. = neutral, common, conversational
• Kitap altmış sayfadır. = a bit more formal, definite, or explanatory

The -dır form is often used in:

• formal writing
• definitions
• general statements
• emphasis

In everyday spoken Turkish, the shorter version without -dır is very common.

The most basic and natural order here is:

• Kitap altmış sayfa.

That is:

• Kitap = subject
• altmış sayfa = predicate

Turkish word order is flexible, but changing it can change the emphasis.

For example:

• Kitap altmış sayfa.
  Neutral: The book is sixty pages.

• Altmış sayfa kitap.
  This usually does not mean the same thing as a full sentence. It sounds more like a sixty-page book as a noun phrase.

So for the sentence meaning, keep:

• Kitap altmış sayfa.

Because it is the subject in a simple nominal sentence, and subjects in Turkish often appear in the basic dictionary form with no extra ending.

Here:

• kitap = book
• altmış sayfa = sixty pages

There is no object here, so you do not need accusative marking or another case ending.

This is just a straightforward statement about the book.

Altmış means sixty.

A rough English-friendly pronunciation is:

• ahl-tmush

A few helpful points:

• ı is not the English ee sound.
• It is a vowel that sounds somewhat like a relaxed, back uh without rounding the lips.
• The ş is like English sh.

So altmış is approximately:

• ahl-tmush

Not perfect, but close enough for a beginner.

No. Sayfa is a noun meaning page.

In altmış sayfa, Turkish uses a number + noun structure, literally sixty page, to express a measurement.

English often turns that into a more natural phrase like:

• sixty pages
• sixty pages long

So sayfa is still a noun, not an adjective.

Yes, definitely.

• Bu kitap altmış sayfa. = This book is sixty pages.

Adding bu makes the reference more specific. Without bu, the sentence is more context-dependent.

Compare:

• Kitap altmış sayfa. = The book / a book is sixty pages.
• Bu kitap altmış sayfa. = This book is sixty pages.

It is a complete and natural sentence.

Nothing important is missing. Turkish commonly allows short, compact sentences like this, especially with measurements, prices, ages, and descriptions.

Similar patterns are:

• Ev büyük. = The house is big.
• Çanta beş kilo. = The bag is five kilos.
• Film iki saat. = The film is two hours.

So Kitap altmış sayfa is a very normal Turkish structure.
