التطبيق بيصنف الصور في المجلد.

A natural Egyptian pronunciation is:

et-taṭbīʔ biyṣannif eṣ-ṣowar fil-mogallad

Word by word:

• التطبيق → et-taṭbīʔ
• بيصنف → biyṣannif
• الصور → eṣ-ṣowar
• في المجلد → fil-mogallad

A few sounds may vary slightly from speaker to speaker, but this is a good practical model.

Because Arabic has sun letters and moon letters.

• In التطبيق, the next letter is ت, which is a sun letter, so ال is pronounced with assimilation: et-taṭbīʔ
• In الصور, the next letter is ص, also a sun letter, so it becomes eṣ-ṣowar
• In المجلد, the next letter is م, a moon letter, so the l sound stays: el-mogallad

Also, في المجلد is often pronounced together as fil-mogallad in natural speech.

In Egyptian Arabic, بيـ usually marks the present/habitual tense.

So بيصنف means something like:

• classifies
• is classifying
• does classify

The exact English translation depends on context, but in a sentence like this it usually matches the English simple present well.

This bi- prefix is very common in Egyptian Arabic and is one of the clearest differences from Standard Arabic.

Because the verb form already tells you the subject is he/it.

بيصنف is a 3rd person masculine singular form, so it already contains the idea of:

• he classifies
• it classifies

Since التطبيق is already stated, Arabic does not need to add a separate subject pronoun.

So:

• التطبيق بيصنف... = The app classifies...

not something like التطبيق هو بيصنف... in normal neutral wording.

Because the verb is really بيصنّف with a shadda on ن.

In normal Arabic writing, short vowels and the shadda are often omitted, so you see:

• بيصنف

but the fuller form is:

• بيصنّف

So the pronunciation is closer to biyṣannif, with a doubled n sound.

Arabic marks definiteness on each noun separately.

So here you have:

• التطبيق = the app
• الصور = the images
• المجلد = the folder

Unlike English, Arabic does not use one the and let it cover everything. Each definite noun normally gets its own ال.

The singular is صورة.

So:

• صورة = one image / picture
• صور = images / pictures

This is a broken plural, which means the inside pattern of the word changes, rather than just adding a regular ending.

Also, notice that the verb does not agree with الصور, because الصور is the object. The subject is التطبيق, so the verb stays singular.

Yes, it is understandable and correct, especially in formal, technical, or written Arabic.

But in everyday Egyptian speech, many people also say:

• الفولدر

So:

• المجلد sounds a bit more formal or standard
• الفولدر sounds more casual and everyday in tech contexts

Both may be heard, depending on the speaker and situation.

Literally, في المجلد means in the folder.

In this sentence, most people will naturally understand it as describing the images:

• the images in the folder

So the whole idea is:

• the app classifies the images that are in the folder

If you want to make that relationship more explicit in Egyptian Arabic, you could say:

• التطبيق بيصنف الصور اللي في المجلد

That version clearly means the images that are in the folder.

Yes, but the given order is very natural.

This sentence uses:

• subject + verb + object + prepositional phrase

So:

• التطبيق = subject
• بيصنف = verb
• الصور = object
• في المجلد = prepositional phrase

That is a very common and natural order in Egyptian Arabic.

Arabic can allow other word orders in some contexts, but for a straightforward sentence like this, the given version is exactly the kind of word order learners should get comfortable with first.
