Ben az uyuyunca sabah yorgun oluyorum.

Yes, Turkish often drops subject pronouns because the verb already shows the person.

• oluyorum = I am becoming / I end up being
• so ben is not strictly necessary

The sentence could simply be:

• Az uyuyunca sabah yorgun oluyorum.

Adding ben gives a little more emphasis or clarity, like As for me... or I... in English. It is grammatically fine either way.

Az means little, not much, or too little depending on context.

So:

• az uyumak = to sleep little / to not sleep much

In this sentence, az uyuyunca means something like:

• when I sleep too little
• when I don’t sleep much

It is a very common adverb and does not need any ending here.

Uyuyunca comes from:

• uyumak = to sleep
• verb stem: uyu-
• -yınca / -yince / -unca / -ünce = when / once / whenever

So:

• uyuyunca = when (someone) sleeps
• in this sentence, because the main verb is I become tired, it is understood as when I sleep little

This ending often gives a meaning like:

• when
• once
• whenever

depending on context.

Examples:

• Eve gelince beni ara. = Call me when you get home.
• Az uyuyunca sabah yorgun oluyorum. = When I sleep little, I am tired in the morning.

Good question. The -ınca/-ince form does not show person by itself.

So uyuyunca literally just means when sleeping happens / when one sleeps. The subject is usually understood from context.

In this sentence, the main clause is:

• sabah yorgun oluyorum = I get/am tired in the morning

Because the speaker is clearly I, we naturally understand the first part as:

• when I sleep little

This is very normal in Turkish. The subject of the -ınca clause is often inferred from the main clause unless something else is stated.

This is one of the most important things in the sentence.

• yorgunum = I am tired
• yorgun oluyorum = I become tired / I end up tired / I am getting tired

In everyday Turkish, oluyorum can also describe a repeated result or usual outcome, not only something happening right this second.

So here:

• sabah yorgun oluyorum means I’m tired in the morning as a recurring consequence of sleeping too little

It sounds more like:

• I end up being tired in the morning
• I get tired in the morning
• I am tired in the morning (as a usual result)

If you said sabah yorgunum, that would sound more like a simple state: I am tired in the morning. With oluyorum, the sentence highlights the result of the previous action.

In Turkish, the present continuous can often be used for habits, repeated situations, and general personal experience, especially in spoken language.

So oluyorum does not have to mean only I am becoming right now. It can also mean:

• I tend to become
• I usually end up
• I am generally

That is why this sentence can express a repeated truth about the speaker:

• When I sleep little, I’m tired in the morning.

Turkish often uses the present continuous this way in natural speech.

Sabah means morning.

In this sentence it works like a time expression:

• sabah yorgun oluyorum = I’m tired in the morning

Turkish often uses time words without extra words like in the if the meaning is clear.

Compare:

• sabah = in the morning
• akşam = in the evening
• bugün = today
• yarın = tomorrow

So sabah here simply tells you when the tiredness happens.

The given sentence is natural:

• Ben az uyuyunca sabah yorgun oluyorum.

But Turkish word order is somewhat flexible. You can move parts around for emphasis.

For example:

• Az uyuyunca sabah yorgun oluyorum.
• Sabah az uyuyunca yorgun oluyorum.
• Sabah yorgun oluyorum az uyuyunca. (possible, but less neutral)

The most neutral pattern here is:

• condition first: az uyuyunca
• then time and result: sabah yorgun oluyorum

So yes, parts can move, but the original version is a good standard one.

Yes, you could, and the meaning would be very similar.

• az uyuyunca
• az uyuduğumda

Both can mean when I sleep little.

The difference is often small and depends on style and nuance:

• -ınca/-ince is very common and often feels a bit more direct or event-based: when/once
• -dığında/-diğinde forms can sound slightly more explicitly tied to a known subject and time frame: when

Because uyuduğumda includes possessive/person marking, it explicitly means when I sleep / when I have slept depending on context.

So:

• Az uyuyunca sabah yorgun oluyorum. = very natural
• Az uyuduğumda sabah yorgun oluyorum. = also natural

Because the cause being described is sleeping too little, not waking up.

• az uyuyunca = when I sleep little
• sabah yorgun oluyorum = I’m tired in the morning

The sentence means the speaker’s tiredness in the morning is the result of not getting enough sleep.

If you used uyandığımda, the meaning would shift to:

• when I wake up

That would focus on the moment of waking, not on the amount of sleep.

Sometimes -ınca/-ince can feel like when or after, depending on context.

For example:

• Eve gelince yemek yedim. = When/After I got home, I ate.

But in this sentence, because of az and the general repeated meaning, uyuyunca is best understood as:

• when I sleep little
• whenever I sleep too little

It is not really about one completed event of sleeping and then something happening after. It is more about a general cause-and-result relationship.

Usually, no. Yorgun means tired, not sleepy.

• yorgun = tired / fatigued
• uykulu = sleepy / drowsy

So:

• sabah yorgun oluyorum = I’m tired in the morning not
• I’m sleepy in the morning unless the context really suggests that idea

If you wanted specifically sleepy, you would more likely say:

• Sabah uykulu oluyorum.

It most naturally describes a general pattern or repeated experience:

• When I sleep too little, I’m tired in the morning.

Several things suggest that:

• -ınca can mean whenever
• oluyorum can express a repeated usual result
• there is no specific time marker like yesterday or last night

If you wanted one specific past event, Turkish would usually use past forms, for example:

• Dün az uyuduğum için sabah yorgundum. = Because I slept little yesterday, I was tired in the morning.
