Bugün kendimi şanslı hissediyorum, çünkü anneanne bana eski bir kitap hediye etti.

Turkish often drops subject pronouns when the verb ending already shows who the subject is.

Here, hissediyorum ends in -um, which tells you the subject is I. So ben is unnecessary unless you want extra emphasis.

• (Ben) kendimi şanslı hissediyorum = I feel lucky
• The ben is optional

This is very common in Turkish.

With hissetmek in this pattern, Turkish often says something like to feel oneself + adjective.

So:

• kendimi = myself
• şanslı = lucky
• kendimi şanslı hissediyorum = literally I feel myself lucky

That is the normal Turkish structure for sentences like:

• Kendimi yorgun hissediyorum = I feel tired
• Kendimi mutlu hissediyorum = I feel happy

Beni would not sound right here, because the reflexive idea myself is what Turkish normally uses.

Kendimi is made from:

• kendi = self
• -m = my
• -i = accusative case

So kendimi means myself as a direct object.

You may also see related forms:

• kendim = myself
• kendine = to yourself / himself / herself
• kendini = yourself / himself / herself
• kendimiz = ourselves

In this sentence, it is the object of hissediyorum.

Because şanslı is an adjective complement after kendimi.

In the pattern kendini + adjective + hissetmek, the adjective usually stays in its basic form:

• kendimi iyi hissediyorum = I feel good
• kendimi kötü hissediyorum = I feel bad
• kendimi şanslı hissediyorum = I feel lucky

So şanslı does not need a case ending here.

It comes from the verb hissetmek, meaning to feel.

Breakdown:

• hisset- = feel
• -iyor = present continuous
• -um = I

So hissediyorum means I am feeling or simply I feel, depending on the context.

In Turkish, the -iyor form is often used where English might use either:

• I am feeling lucky
• I feel lucky

Both ideas can fit, depending on context.

Bugün means today, and time expressions often come near the beginning of a Turkish sentence.

That makes the time frame clear right away:

• Bugün kendimi şanslı hissediyorum = Today I feel lucky

Turkish word order is flexible, but putting time words early is very common and natural.

Both can be possible, but they feel slightly different.

• anneanne = grandmother / grandma, specifically maternal grandmother
• anneannem = my maternal grandmother

In Turkish, family words are often used almost like names or titles in context, so anneanne can sound natural, especially in everyday speech.

So:

• Anneanne bana kitap verdi = Grandma gave me a book
• Anneannem bana kitap verdi = My grandmother gave me a book

The second one is more explicitly my grandmother, but the first can also sound perfectly natural when the relationship is obvious.

Bana is the dative form of ben, and it means to me.

Here, the gift is given to me, so Turkish uses the dative:

• bana = to me
• sana = to you
• ona = to him / her / it

So:

• anneanne bana eski bir kitap hediye etti = Grandma gave me an old book as a gift

This is the normal pattern for a recipient in Turkish.

In standard Turkish, when you have an adjective plus bir meaning a/an, the usual order is:

• adjective + bir + noun

So:

• eski bir kitap = an old book
• güzel bir ev = a beautiful house
• uzun bir gün = a long day

That is why eski bir kitap is the normal order here.

Here, bir works like the English indefinite article a/an.

So:

• kitap = book
• bir kitap = a book
• eski bir kitap = an old book

Sometimes bir can also mean one, but in this sentence it is just introducing an indefinite noun: an old book.

Hediye etti comes from the expression hediye etmek, which means to give as a gift or to present.

Breakdown:

• hediye = gift
• etmek = to do / to make, but it often helps form compound verbs

So hediye etmek is a compound verb, and that is why it is written as two words.

In this sentence:

• hediye etti = gave as a gift / gifted

It is in the past tense, third person singular:

• etti = he/she did, or here, gave

So anneanne bana eski bir kitap hediye etti means that Grandma gave me an old book as a gift.

Because Turkish usually places the main verb at the end of the clause.

You can see that in both parts:

• Bugün kendimi şanslı hissediyorum
• çünkü anneanne bana eski bir kitap hediye etti

This end-position for the verb is one of the most important word-order habits in Turkish.

A rough structure here is:

• Bugün = time
• kendimi = object
• şanslı = complement
• hissediyorum = verb

and

• anneanne = subject
• bana = recipient
• eski bir kitap = object
• hediye etti = verb

Çünkü means because.

It introduces the reason for the first clause:

• Bugün kendimi şanslı hissediyorum = Today I feel lucky
• çünkü anneanne bana eski bir kitap hediye etti = because Grandma gave me an old book

So the whole sentence means:

• I feel lucky today, because Grandma gave me an old book.

After çünkü, Turkish still keeps its normal clause structure, with the verb at the end.

The comma separates the two clauses in writing:

• main statement
• reason clause

So it helps readability:

• Bugün kendimi şanslı hissediyorum, çünkü...

This is similar to English punctuation before because in some sentence styles, although punctuation rules are not always identical between the two languages. In Turkish writing, the comma here is natural and clear.
