اختي طلبت مصروف اكتر هالشهر لانه عندها كتب جديدة.

A common Levantine pronunciation would be:

ekhte talabet masruuf aktar hal-shahr la'anno ʿendha kotob jdiide

A few notes:

• اختي is often pronounced ekhte in Levantine.
• طلبت here is talabet = she asked.
• هالشهر is hal-shahr = this month.
• لانه is often pronounced la'anno or la'ennu, depending on region.
• جديدة is often pronounced jdiide.

There is some regional variation, so you may hear slightly different vowels.

اختي = أخت + ي

• أخت = sister
• -ي = my

So literally it is my sister.

This is very common in Arabic: possession is often shown by attaching a suffix to the noun instead of using a separate word like my.

Examples:

• أمي = my mother
• أبي / ابوي = my father
• بيتي = my house

Because the subject is اختي = my sister, which is feminine.

In the past tense, Levantine verbs usually agree with the subject. So:

• طلب = he asked
• طلبت = she asked

Here, طلبت matches اختي.

So the structure is:

• اختي = my sister
• طلبت = asked

Together: My sister asked

Yes. In Arabic writing without short vowels, طلبت can represent both:

• I asked
• she asked

Context tells you which one is meant.

In this sentence, because the subject اختي comes right before it, the meaning is clearly my sister asked.

In speech, the forms are usually pronounced differently enough to help:

• talabt = I asked
• talabet = she asked

So spoken Arabic makes the distinction clearer than unvoweled writing.

Because Levantine very often prefers subject + verb order in everyday speech.

So:

• اختي طلبت... = My sister asked...

This is extremely natural in spoken Levantine.

Arabic can also use verb-first order, but in colloquial Levantine, starting with the subject is very common, especially in ordinary conversation.

مصروف usually means allowance, spending money, or money given for expenses.

In this sentence, it most naturally means allowance/spending money.

Depending on context, مصروف can also refer more generally to expenses or money spent, but here the idea is clearly that she asked for more money to use.

Yes. اكتر is the colloquial Levantine form of أكثر.

It means more.

So:

• مصروف اكتر = more allowance / more spending money

In spoken Levantine, اكتر is much more natural than the formal أكثر.

Also, there is no من here because the sentence is not explicitly saying more than something. It just means more allowance.

If you wanted to say more than last month, you could say something like:

• اكتر من الشهر الماضي

هالشهر means this month.

It is made from:

• هال- = this
• شهر = month

So هالشهر is a very common Levantine way to say this month.

Compared with هذا الشهر:

• هذا الشهر is more formal / MSA-like
• هالشهر is more natural in Levantine speech

You will see هال- with many nouns:

• هالبيت = this house
• هالبنت = this girl
• هاليومين = these two days / these days

لانه means because here.

In Levantine, this is often pronounced:

• la'anno
• sometimes la'ennu

It corresponds to formal Arabic لأن or لأنه in many contexts, but in spoken Levantine it functions simply as the everyday word for because.

So:

• لانه عندها كتب جديدة = because she has new books

The -o in the pronunciation is part of the conjunction as people normally say it; you do not need to think of it as meaning he here.

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

• عند literally has the sense of at / with
• عندها = at her / with her

But in natural English, this often translates as she has.

So:

• عندها كتب literally: at her are books
• natural English: she has books

Other examples:

• عندي = I have
• عندك = you have
• عنده = he has
• عندهم = they have

This is one of the main ways Levantine says have.

This is a very common learner question.

كتب is a non-human plural noun: books.

In Arabic, non-human plurals are very often treated grammatically like feminine singular, especially in more standard or neutral styles. That is why the adjective appears as:

• جديدة = feminine singular

So:

• كتب جديدة = new books

In spoken Levantine, you may also hear كتب جداد, which is a more colloquial plural adjective form and is also natural in many areas.

So for Levantine:

• كتب جديدة = very common and completely correct
• كتب جداد = also common in everyday speech

The version in your sentence is perfectly normal.

It is mostly colloquial Levantine, but like a lot of everyday written Arabic online, it sits in a mixed informal register.

Colloquial features include:

• اكتر
• هالشهر
• the overall spoken-style phrasing

At the same time, some words like كتب جديدة look a bit closer to a neutral written style than to the most casual street-level speech.

That is very typical. A lot of written Levantine is not purely phonetic dialect spelling; people often mix colloquial grammar and vocabulary with spellings that look somewhat more standard.
