التحميص بيغير درجة التحميص.

A natural pronunciation is:

et-taḥmīṣ biyghayyar daragit et-taḥmīṣ

A few notes:

• ال before ت is pronounced as et-, not al-, because ت is a sun letter.
• بيغير is often pronounced biyghayyar or beyghayyar, depending on the speaker.
• درجة becomes daragit here because it is followed by another noun in an iḍāfa structure: daragit et-taḥmīṣ = the degree of roasting / roast level.

بيغير means changes or is changing.

It comes from the verb غيّر = to change / alter something.

In Egyptian Arabic:

• بيـ often marks the habitual or present tense
• يغير = he changes
• so بيغير = he changes / it changes

In this sentence, it means:

• Roasting changes...
• or more naturally in English, Roasting affects the roast level

Yes, it is the same noun both times: التحميص = roasting.

But it plays two different roles in the sentence:

1. The first التحميص is the subject:
   التحميص = roasting

2. The second التحميص is part of the phrase
   درجة التحميص = the degree of roasting / roast level

So the repetition is grammatical, even if it sounds a bit repetitive in English.

Because both uses are definite.

• التحميص = the roasting, but in Arabic this can also mean roasting in general as a concept
• درجة التحميص = the degree of the roasting or more naturally the roast level

Arabic often uses the definite article in places where English might prefer a more general or abstract noun without the.

So التحميص here can be understood as a general process, not necessarily one specific roasting event.

It is an iḍāfa construction, often called a genitive construction or noun + noun structure.

Here:

• درجة = degree
• التحميص = roasting

Together:

• درجة التحميص = degree of roasting
• more naturally: roast level

In Arabic, this kind of structure usually works like:

• first noun = the thing being described
• second noun = what it belongs to or is related to

Examples:

• باب البيت = the door of the house
• لون القهوة = the color of the coffee
• درجة التحميص = the degree of roasting

Because in an iḍāfa construction, the first noun usually does not take الـ.

So you say:

• درجة التحميص

not

• الدرجة التحميص

The whole phrase can still be definite because the second noun is definite:

• درجة التحميص = the roast level

This is a very important Arabic pattern.

This is a very common Egyptian Arabic feature.

The word درجة on its own is often pronounced something like:

• daraga

But when it is in an iḍāfa before another noun, the ـة often becomes pronounced as -it:

• daragit et-taḥmīṣ

So:

• alone: daraga
• before another noun: daragit...

This happens with many feminine nouns ending in ـة in Egyptian Arabic.

Because the subject التحميص is a singular noun.

Even though English may treat words like roasting as an activity or process, in Arabic التحميص is still grammatically a singular noun, so the verb is singular too:

• التحميص بيغير... = Roasting changes...

This is completely normal.

It is a noun here.

More specifically, it is a verbal noun: a noun derived from a verb, similar to English words like:

• roasting
• heating
• mixing

So التحميص names the process or act of roasting.

That is why it can act as the subject of the sentence.

The base verb is حمّص.

In Egyptian Arabic, حمّص means to roast.

From that verb, you get the verbal noun:

• تحميص = roasting

This pattern is common in Arabic:

• verb: غيّر = to change
• noun: تغيير = changing / change

and similarly:

• verb: حمّص = to roast
• noun: تحميص = roasting

That is very common with Egyptian Arabic.

Spoken Egyptian is often written using standard Arabic spelling conventions, even when the grammar and vocabulary are colloquial.

Here:

• التحميص and درجة look the same as in more formal Arabic writing
• بيغير is clearly Egyptian/colloquial because of the بيـ present-tense marker

So the sentence is written in normal Arabic script, but the language itself is Egyptian Arabic.

Yes, but the given order is very natural.

The sentence starts with the subject:

• التحميص بيغير درجة التحميص

This is a common subject + verb + object pattern in Egyptian Arabic.

You could sometimes hear rephrased versions depending on emphasis, but this one is straightforward and natural for everyday speech.

In Egyptian Arabic, بيغير usually gives a present / habitual / general meaning.

So here it most naturally means:

• changes
• affects
• alters

as a general fact.

If the sentence is talking about a process in general, this is exactly the form you would expect.

Yes, mainly the verb form بيغير.

That بيـ prefix is a strong clue that this is Egyptian Arabic (and also found in some other dialects, though not in the same way as Standard Arabic).

Also, the likely pronunciation:

• et-taḥmīṣ
• biyghayyar
• daragit et-taḥmīṣ

is distinctly Egyptian in sound.

So even though the spelling is fairly standard-looking, the sentence is definitely colloquial Egyptian in grammar and pronunciation.
