درجة التحميص غامقة.

Word by word:

• درجة = degree, level
• التحميص = the roasting / roast
• غامقة = dark

So the structure is literally something like:

• درجة التحميص = the roast level / the degree of roasting
• غامقة = dark

Yes. درجة very often means more than just degree in the narrow English sense. In Arabic, it can also mean:

• level
• grade
• degree
• extent

So درجة التحميص naturally means the roast level or the degree of roasting.

This is similar to other common phrases like:

• درجة الحرارة = temperature, literally degree of heat

A good approximate pronunciation is:

daraget et-taḥmīṣ ghāmeʔa

You may also hear something closer to:

daraget et-taḥmīṣ ghāmʔa

A few helpful notes:

• ج in Egyptian is usually a hard g sound.
• ال before ت gets assimilated, so التحميص sounds like et-taḥmīṣ, not el-taḥmīṣ.
• ق in Egyptian is often pronounced as a glottal stop ʔ, especially in everyday speech.

Because Arabic usually leaves out the verb to be in the present tense.

So instead of saying:

• The roast level is dark

Arabic just says:

• درجة التحميص غامقة
• literally: the roast level dark

This is completely normal. It is called a nominal sentence.

If you wanted past or future, then Arabic would use a verb.

Because it agrees with درجة, and درجة is a feminine noun.

In Arabic, adjectives agree with the noun they describe in gender and number. Here:

• درجة = feminine
• so the adjective must also be feminine
• غامقة = feminine form of dark

If the noun were masculine, you would use:

• غامق = dark, masculine

Good question. The adjective agrees with the head noun, not with the second noun in the phrase.

Here the full noun phrase is:

• درجة التحميص = the roast level

The main noun in that phrase is درجة, not التحميص.

So the adjective describes درجة, and that is why you get:

• غامقة and not غامق

If you changed the sentence to make التحميص itself the thing being described, then غامق would make sense:

• التحميص غامق = the roast / roasting is dark

Because this is a construct phrase (often called iḍāfa).

In a phrase like:

• درجة التحميص

the first noun often does not take الـ. The whole phrase becomes definite because the second noun is definite:

• التحميص = the roasting / the roast

So:

• درجة التحميص = the roast level

This is a very common Arabic pattern.

Because درجة is followed by another noun in a construct phrase.

On its own, درجة is usually pronounced something like:

• daraga

But when it is linked to the next word, the ة is pronounced:

• daraget et-taḥmīṣ

This happens a lot with words ending in ة when they are connected grammatically to what follows.

التحميص is a verbal noun: a noun derived from a verb.

It comes from the verb حمّص = to roast / to toast.

So التحميص means:

• roasting
• the process of roasting
• roast, depending on context

Arabic often uses this kind of noun where English might use a more specialized noun phrase.

The written sentence can be understood in both.

What makes it feel Egyptian is mostly the pronunciation:

• ج pronounced as g
• ق often pronounced as ʔ
• الـ often sounding like el / et

In Modern Standard Arabic, the same written words are fine, but the pronunciation would be different and more formal.

So you can think of it as a sentence that works in both, with Egyptian-style pronunciation in everyday speech.

For the negative in Egyptian Arabic, you can say:

• درجة التحميص مش غامقة = the roast level isn’t dark

To ask it as a yes/no question, you can usually just use rising intonation:

• درجة التحميص غامقة؟ = Is the roast level dark?

In everyday Egyptian, intonation is often enough. A formal هل is more MSA than conversational Egyptian.
