كتبت النقطة بالدفتر.

A common Levantine-style pronunciation would be something like:

• katabt en-noʔṭa bid-daftar if the subject is I
• katabet en-noʔṭa bid-daftar if the subject is she

A few notes:

• ق in النقطة is often pronounced as a glottal stop ʔ in many Levantine accents.
• ال changes its pronunciation before certain letters, so you hear en-noʔṭa and bid-daftar, not a clear al-.
• Exact vowels vary by region, so you may also hear slightly different pronunciations.

Because normal Arabic spelling usually leaves out short vowels.

So كتبت can represent more than one spoken form:

• katabt = I wrote
• katabet = she wrote

In fully vowelled Arabic, these would be written differently, but in everyday writing they both appear as كتبت. Native speakers use context to tell which one is meant.

It is part of the past-tense verb ending.

The basic root idea is k-t-b, related to writing. In the past tense, endings get added to show the subject.

In this written form, the final ت is what gives you forms like:

• katabt = I wrote
• katabet = she wrote

So the ت is not random; it is doing grammatical work.

In many Levantine accents, ق is often pronounced as a glottal stop ʔ rather than q.

So a word historically like nuqṭa is often said more like:

• noʔṭa
• niʔṭa

depending on the region and speaker.

That is a very common feature of Levantine Arabic. Some speakers, however, do keep ق as q, so pronunciation can vary.

Because ن is a sun letter.

When الـ comes before a sun letter, the l sound assimilates to the next consonant. So:

• النقطة is written with ال
• but pronounced more like en-noʔṭa or in-niʔṭa, depending on dialect

The same thing happens in بالدفتر because د is also a sun letter. So that part is pronounced more like bid-daftar, not bil-daftar.

In Levantine Arabic, بـ is very flexible. It can mean things like:

• in
• at
• with
• by

depending on context.

Here, بالدفتر is understood as a location, so it means in the notebook.

It is made from:

• بـ = a preposition
• الدفتر = the notebook

In Levantine, using بـ this way is very natural. You may also hear في الدفتر, which is a more direct way to say in the notebook.

نقطة is a very common word with several related meanings. Depending on context, it can mean:

• dot
• point
• period / full stop
• a point in an argument or discussion

So the exact sense comes from context. Arabic often uses one word for several closely related ideas like this.

That final ة is called taa marbuuTa.

It often marks a noun as grammatically feminine. In pronunciation, it usually sounds like:

• -a or -e when you stop on the word

So نقطة is pronounced like noʔṭa / niʔṭa, not with a strong final t in pause.

But in some grammatical situations, especially when something comes after it in a linked structure, that ending may sound like t again.

Yes. Starting with the verb is very normal in Arabic.

So كتبت النقطة بالدفتر has a natural Arabic word order. Arabic often likes:

• verb + rest of the sentence

If you want to make the subject extra clear, you can add it:

• أنا كتبت النقطة بالدفتر = I wrote ...
• هي كتبت النقطة بالدفتر = she wrote ...

That is especially helpful here because كتبت by itself is ambiguous in writing.

Yes, you often can.

Both can work, but they do not always feel exactly the same in every context.

• بالدفتر is very natural in Levantine and often used in everyday speech
• في الدفتر is more explicitly in the notebook

In this sentence, both are understandable. A learner should recognize that Levantine frequently uses بـ where English would use in.

The spelling can fit both, but the way you might say or understand it can be Levantine.

Why?

• The written words themselves are not unusual in Standard Arabic.
• But features like pronouncing ق as ʔ and using بـ very naturally for location are especially associated with Levantine speech.
• Also, everyday Arabic writing often looks more standard than actual spoken pronunciation.

So a Levantine learner should think: standard-looking spelling, but colloquial pronunciation and usage are very possible.
