Sunum notunu dikkatle okuyorum.

Turkish does not use articles the way English does.

In this sentence, sunum notunu is understood as a specific direct object, so it often corresponds to the presentation note in English. Turkish shows this kind of specificity partly through the accusative ending on the object.

Compare:

• Sunum notunu okuyorum = I am reading the presentation note
• Sunum notu okuyorum = I am reading a presentation note / presentation notes

So there is no separate word for the, but the grammar helps express that idea.

Because the word is doing two jobs at once.

The base noun compound is:

• sunum notu = presentation note

Then, because it is a specific direct object, Turkish adds the accusative ending:

• sunum notu → sunum notunu

So notunu contains:

• not = note
• -u = the compound ending on the second noun
• -nu = the accusative ending, with a buffer n

That is why you see -unu at the end.

Sunum notu is a very common Turkish noun-compound pattern.

It is made from:

• sunum = presentation
• notu = note, with the compound ending

Even though this ending looks like a possessive ending, here it is simply part of the normal way Turkish builds many noun+noun expressions.

Similar patterns:

• ders kitabı = course book
• otobüs durağı = bus stop
• telefon numarası = phone number

So sunum notu does not really mean that the presentation literally owns the note. It just means presentation note.

That n is a buffer consonant.

When a noun already has a possessive/compound-type ending and then another ending is added, Turkish often inserts n to make pronunciation smoother.

So:

• notu
  • accusative → notunu

Not:

• notuu

This same buffer n appears in many similar forms.

Okuyorum breaks down like this:

• oku- = read
• -yor- = present continuous / ongoing action
• -um = I

So:

• okuyorum = I am reading

This is one of the most common Turkish verb forms. It usually refers to an action happening now or around now.

Because Turkish verbs usually already show the subject.

In okuyorum, the ending -um tells you the subject is I. So ben is not necessary.

You could say:

• Ben sunum notunu dikkatle okuyorum

But that would usually add emphasis, as if you were stressing I.

Because dikkatle functions like an adverb here.

• dikkatli = careful, attentive
  This is more like an adjective.
• dikkatle = carefully, with attention
  This is what fits the sentence.

So:

• dikkatli öğrenci = careful student
• dikkatle okuyorum = I read carefully

You may also hear:

• dikkatlice
• dikkatli bir şekilde

But dikkatle is short, natural, and common.

Yes, this word order is normal.

Turkish usually puts the verb at the end, and that is exactly what happens here:

• Sunum notunu dikkatle okuyorum

A fuller version would be:

• Ben sunum notunu dikkatle okuyorum

Since ben is often omitted, the given sentence sounds perfectly natural.

You can move some parts for emphasis, for example:

• Dikkatle sunum notunu okuyorum

This puts a bit more focus on carefully. But the most important general rule is that the verb commonly comes last.

Here it is singular.

If you wanted to say the presentation notes, you would normally use a plural form such as:

• Sunum notlarını dikkatle okuyorum

So in the original sentence, notunu refers to one specific note. English sometimes uses notes where Turkish may use a singular form depending on context, so it is worth watching the endings carefully.
