Gece televizyon açık kalınca uyuyamadım.

Kalınca comes from the verb kalmak (to stay, remain) plus the suffix -ınca / -ince, which often means when, once, or sometimes because depending on context.

So:

• kalmak = to stay/remain
• kalınca = when it stayed/remained, or in natural English here, because it stayed

In this sentence, televizyon açık kalınca means something like:

• when the TV stayed on
• since the TV stayed on
• because the TV was left on

The exact English wording depends on context, but the Turkish structure is very natural.

Yes, açık literally means open, but it is also the normal word for something being on, especially for devices, lights, TVs, radios, etc.

So:

• kapı açık = the door is open
• ışık açık = the light is on
• televizyon açık = the TV is on

In this sentence, açık does not mean the TV is physically open. It means the TV was on.

Açık kalmak is a very common expression meaning to remain open/on or to be left open/on.

Examples:

• Kapı açık kaldı. = The door stayed open.
• Işık açık kaldı. = The light was left on.
• Televizyon açık kaldı. = The TV stayed on / was left on.

So in your sentence, televizyon açık kalınca means the TV stayed on or was left on.

Because these mean different things.

• televizyonu açınca = when I/someone turned on the TV
• televizyon açık kalınca = when the TV remained on / was left on

The sentence is not talking about the action of turning the TV on. It is talking about the state of the TV still being on, and that state caused the speaker not to sleep.

So:

• açmak = to open / turn on
• açık olmak = to be open / be on
• açık kalmak = to stay open / stay on

Uyuyamadım can be broken down like this:

• uyu- = sleep
• -ya- = linking sound
• -ma- = negation inside the ability form
• -dı = past tense
• -m = I

So uyuyamadım means I couldn’t sleep.

This is different from:

• uyumadım = I didn’t sleep

That difference is important:

• uyumadım = I did not sleep
• uyuyamadım = I was unable to sleep / I couldn’t sleep

In this sentence, uyuyamadım is the better choice because the TV being on prevented sleep.

Because Turkish often leaves out subject pronouns when they are already clear from the verb ending.

Here, -m at the end of uyuyamadım already tells you the subject is I.

So:

• uyuyamadım = I couldn’t sleep
• ben uyuyamadım = I couldn’t sleep

Both are possible, but ben is often omitted unless you want extra emphasis or contrast.

Gece here means at night / during the night.

Turkish often uses bare time words without a preposition where English would use at, in, or during.

So:

• gece = at night
• sabah = in the morning
• dün = yesterday
• bugün = today

Starting the sentence with Gece sets the time frame first, which is very natural in Turkish.

Because many common time expressions in Turkish appear without a case ending.

So gece by itself can mean at night. This is normal and idiomatic.

You may also see forms like:

• gecede — not used this way for basic at night
• geceleyin = during the night / at night
• bu gece = tonight

In this sentence, simple gece is the natural choice.

No. -ınca / -ince often means when or once, but in many contexts it can also feel like because, especially when one event leads to another.

For example:

• Eve gelince beni ara. = Call me when you get home.
• Yağmur yağınca maç iptal oldu. = The match was canceled when / because it rained.

In your sentence, the idea is causal:

• Televizyon açık kalınca uyuyamadım.
• literally: When the TV stayed on, I couldn’t sleep
• natural sense: Because the TV was left on, I couldn’t sleep

So the suffix itself does not always mean because, but context can make it feel that way.

No, Turkish word order is flexible, although some orders sound more neutral than others.

Your sentence:

• Gece televizyon açık kalınca uyuyamadım.

is a very natural order.

You could also hear things like:

• Televizyon açık kalınca gece uyuyamadım.
• Gece uyuyamadım, televizyon açık kalınca.

But changing the order can shift emphasis or sound more marked.

A useful rule is:

• the main verb usually comes at the end
• information earlier in the sentence often sets the scene or topic
• the part just before the verb is often emphasized

So here, putting Gece first gives a time setting, and the whole clause leads naturally to uyuyamadım at the end.

Turkish has no articles like a or the.

So televizyon can mean:

• a television
• the television
• TV

The exact meaning depends on context.

In this sentence, English would usually say the TV because both speaker and listener presumably know which TV is meant, but Turkish does not need a special word for that.

Yes, depending on context, uyuyamadım can often be understood as I couldn’t get to sleep / fall asleep as well as I couldn’t sleep.

The verb uyumak is to sleep, but in negative ability form it often naturally covers the idea of not being able to fall asleep.

If someone wanted to be more specific about falling asleep, they might say:

• uykuya dalamadım = I couldn’t fall asleep

But uyuyamadım is completely normal and natural here.
