اختي عندها جاكيت لانه برد كتير اليوم.

One common Levantine-style pronunciation is:

ekhte ʿenda jacket laʾanno bard kteer il-yom

A few notes:

• اختي is often pronounced ekhte in Levantine, though some speakers say something closer to ikhti.
• عندها may sound like ʿenda or ʿindha, depending on the region.
• لانه is often pronounced laʾanno or laʾenno.
• اليوم may sound like il-yom or el-yom.

So pronunciation can vary a bit across Syria, Lebanon, Jordan, and Palestine.

اختي means my sister.

It is made of:

• اخت / أخت = sister
• -ي = my

So the -ي ending is a possessive suffix meaning my.

Also, you may see this written as أختي in more careful or standard spelling. In casual texting or informal writing, people often drop the hamza and write اختي.

In Levantine Arabic, possession is often expressed with عند plus a pronoun suffix.

So:

• عند = literally at
• ها = her

Together, عندها literally means at her, but in normal English we translate it as she has.

This is a very common Arabic pattern:

• عندي = I have
• عندك = you have
• عنده = he has
• عندها = she has

So اختي عندها جاكيت is literally something like my sister, at her, a jacket, but naturally it means my sister has a jacket.

Yes. جاكيت is a very common borrowed word in spoken Arabic, especially in dialects. It means jacket.

Levantine Arabic uses many everyday loanwords, especially for modern clothing and objects. So this is completely normal.

A couple of useful points:

• جاكيت without ال means a jacket
• الجاكيت means the jacket

So here, جاكيت is indefinite: a jacket.

Yes. Here لانه means because.

In more careful spelling, you may also see:

• لأنه
• لإنه
• and in very colloquial Levantine often لأنه or لأنو

In everyday speech, learners can usually just treat it as the connector because.

Historically, it comes from a structure related to because it is, but in practice you do not need to analyze it that way every time. In this sentence, it simply links the two ideas:

• اختي عندها جاكيت
• لانه برد كتير اليوم

= My sister has a jacket because it’s very cold today.

Arabic normally does not use a present-tense verb meaning is/am/are in sentences like this.

So:

• برد كتير اليوم literally looks like cold very today
• but it means it is very cold today

This is very normal in Arabic. The present-tense copula is usually omitted.

The same thing happens in other simple sentences:

• الجو حلو = the weather is nice
• أنا تعبان = I am tired
• هي مشغولة = she is busy

So there is no missing word here. The sentence is complete as it stands.

This is a great question, because both forms are related to cold, but they are used differently.

In Levantine, برد is very commonly used in weather expressions to mean it’s cold or cold weather:

• اليوم برد = it’s cold today
• برد كتير = it’s very cold

بارد, on the other hand, is the adjective cold and is often used to describe a noun:

• الجو بارد = the weather is cold
• المي باردة = the water is cold

So in this sentence, برد كتير اليوم is a natural colloquial way to say it’s very cold today.

كتير means a lot or very, depending on context.

Here it works like very:

• برد كتير = very cold

This is one of the most common words in Levantine Arabic.

Examples:

• بحبك كتير = I love you a lot
• هالشي حلو كتير = this is very nice
• تعبان كتير = very tired

So in your sentence, كتير is intensifying برد.

Strictly speaking, عندها جاكيت means she has a jacket. It does not automatically mean she is wearing it.

If you want to say she is wearing a jacket, Levantine would more naturally use:

• أختي لابسة جاكيت

So your sentence is grammatical, but in real-life context, an English speaker might expect wearing rather than just has, because the reason given is the cold weather.

That means:

• اختي عندها جاكيت لانه برد كتير اليوم = she has a jacket / has one with her
• اختي لابسة جاكيت لانه برد كتير اليوم = she is wearing a jacket because it’s very cold today

Yes, it can go in other places. Arabic word order is often flexible, especially with time words like اليوم.

Your sentence says:

• برد كتير اليوم = it’s very cold today

But you could also hear:

• اليوم برد كتير

Both are natural. The difference is mostly about emphasis and style, not basic meaning.

Putting اليوم at the end is very normal in speech. It lets the speaker first state the condition برد كتير and then add the time frame today.

It is clearly colloquial / spoken-style Arabic, especially Levantine-leaning.

Some clues:

• عندها used for has is very common in spoken Arabic
• كتير is colloquial Levantine; Standard Arabic would be كثيرًا or would phrase things differently
• برد كتير اليوم is a spoken-style weather expression
• جاكيت is an everyday borrowed word typical of dialect speech
• casual spelling like اختي and لانه also points to informal writing

A more Standard Arabic version would look different, for example:

• أختي لديها سترة لأنه بارد جدًا اليوم

But that sounds much more formal and less conversational.
