المقاول بيعمل الترميم.

In everyday Egyptian Arabic, subject–verb–object order is very common:

المقاول بيعمل الترميم
= the contractor is doing the restoration

So starting with المقاول sounds natural in speech. Arabic can also use verb-first order in some situations, but this subject-first pattern is extremely common in Egyptian.

In Egyptian Arabic, بـ usually marks the normal present tense. It often covers both:

• does
• is doing

So بيعمل can mean does, is doing, or carries out, depending on context.

The verb عمل is a very flexible verb. It can mean:

• do
• make
• carry out
• sometimes work

In this sentence, because it is followed by الترميم, it means something like:

• is doing the restoration
• is carrying out the renovation
• is doing the repair work

So here it is not just make in the literal English sense.

It is not stated as a separate word. In Arabic, the present-tense verb already contains the idea that English often expresses with is + -ing.

So بيعمل by itself can correspond to is doing.

ال is the Arabic definite article, equivalent to English the.

So:

• المقاول = the contractor
• الترميم = the restoration / the renovation

This makes both nouns definite and specific.

That is a normal feature of Egyptian Arabic pronunciation. In Egyptian speech, the definite article ال is usually pronounced el-.

So:

• المقاول is often pronounced roughly el-moʔawel
• not the more standard-style al-muqāwil

Because in Egyptian Arabic, the letter ق is very often pronounced as a glottal stop ʔ in everyday speech.

So مقاول is commonly pronounced something like:

moʔawel

rather than the more formal/standard-style pronunciation with q.

Because ت is a sun letter. With sun letters, the ل in ال is not pronounced. Instead, the next consonant is doubled.

So:

• written: الترميم
• pronounced: roughly et-tarmīm

The spelling does not change, but the pronunciation does.

الترميم is a verbal noun, often called a masdar. It means something like:

• restoration
• renovation
• repair work

So the sentence literally has the structure:

the contractor does the restoration

Even though natural English may prefer is restoring or is doing the renovation.

It can sound a bit more technical or formal than a very general word like repair. It is especially natural for things like:

• building restoration
• renovation
• structural repair
• restoration of an old place

So it fits well with المقاول.

Because it agrees with a third-person singular masculine subject:

المقاول = the contractor

In Egyptian Arabic, verbs change according to person, number, and sometimes gender. So بيعمل matches he / it.

For example, with a plural subject, the verb would change:

المقاولين بيعملوا الترميم
= The contractors are doing the restoration

Yes, but the meaning becomes less specific.

For example:

مقاول بيعمل ترميم

could mean something like:

• a contractor is doing restoration
• a contractor does renovation work

Using ال makes the sentence refer to a specific contractor and a specific restoration job.

Not most naturally in this sentence. Because بيعمل is taking a direct object, الترميم, the meaning is more like does / carries out.

If you wanted to say works in restoration, Egyptian Arabic often uses a different verb, for example:

المقاول بيشتغل في الترميم
= The contractor works in restoration
