عندنا اجتماع مع المدير الساعة سبعة الصبح.

A natural Egyptian-style pronunciation is:

ʿandena egtimāʿ maʿ el-modīr es-sāʿa sabʿa ṣ-ṣobḥ

A simpler learner-friendly version:

an-DE-na eg-te-MAʿ maʿ el-mo-DEER es-SA-a SAB-a s-SOBH

A few notes:

• ج in Egypt is usually pronounced like g in go, so اجتماع sounds like egtimāʿ.
• الساعة is usually pronounced es-sāʿa.
• الصبح is usually pronounced with an emphatic s, roughly ṣ-ṣobḥ.

عندنا literally means at us, but in everyday Arabic it usually means we have.

It breaks down like this:

• عند = at / by / with
• نا = us / our

So عندنا اجتماع literally means something like at us, there is a meeting, which English expresses as we have a meeting.

Because Egyptian Arabic usually does not use a verb like English have in this kind of sentence.

Instead, possession is often expressed with عند:

• عندي = I have
• عندك = you have
• عندنا = we have

So:

• عندنا اجتماع = we have a meeting

This is a very common Arabic pattern.

Yes. In Arabic, especially in the present tense, sentences often do not need an explicit verb like is, are, or have.

So عندنا اجتماع is perfectly complete and natural.

You can think of it as:

• We have a meeting
• or more literally, There is a meeting with us

Both ideas are built into the Arabic structure.

اجتماع means meeting.

Yes, it is a very common word in both formal Arabic and everyday speech. In Egyptian Arabic, people use it naturally in work, school, and official contexts.

Examples:

• عندي اجتماع = I have a meeting
• كان عندنا اجتماع مهم = We had an important meeting

In Egyptian pronunciation, اجتماع is often said as egtimāʿ.

مع means with, so:

• مع المدير = with the manager

This tells you who the meeting is with.

Also:

• المدير = the manager / the director
• الـ = the

So the phrase is very straightforward:

• اجتماع مع المدير = a meeting with the manager

الساعة literally means the hour or the clock, but in everyday Arabic it is also used when telling time.

So:

• الساعة سبعة = seven o’clock

In this sentence, it introduces the time of the meeting.

English usually says at seven, but Arabic often just says:

• الساعة سبعة

without needing a separate word for at.

Because when Egyptians tell the hour, they commonly use the number directly after الساعة:

• الساعة واحدة = one o’clock
• الساعة اتنين = two o’clock
• الساعة تلاتة = three o’clock
• الساعة سبعة = seven o’clock

So الساعة سبعة is the normal everyday way to say seven o’clock.

Yes. الصبح means the morning, and in this sentence it works like in the morning or AM.

So:

• سبعة الصبح = seven in the morning / 7 AM

This is very common in Egyptian Arabic.

More formal alternatives would be things like:

• صباحًا
• في الصباح

But الصبح is the natural everyday Egyptian choice.

Because Arabic often does not need it in this structure.

English says:

• at seven in the morning

But Egyptian Arabic very naturally says:

• الساعة سبعة الصبح

The time expression itself is enough, so no extra word like at is required.

The given order is very natural:

• عندنا اجتماع مع المدير الساعة سبعة الصبح

But Arabic word order is flexible, so you can move parts around for emphasis.

For example:

• الساعة سبعة الصبح عندنا اجتماع مع المدير

That is still understandable, but the original version sounds very natural in everyday speech.

It is very natural as Egyptian Arabic, though much of it is widely understandable.

What makes it feel colloquial/Egyptian includes things like:

• عندنا for we have
• الساعة سبعة
• الصبح for in the morning
• no case endings

A more formal Standard Arabic version would be something like:

لدينا اجتماع مع المدير الساعة السابعة صباحًا

So the sentence you have is excellent everyday spoken Arabic.

No.

This is because of sun letters and moon letters.

• In المدير, the ل is pronounced, because م is a moon letter.
  So it sounds like el-modīr.

• In الساعة, the ل assimilates to س, because س is a sun letter.
  So it sounds like es-sāʿa, not el-sāʿa.

• In الصبح, the ل also assimilates, because ص is a sun letter.
  So it sounds like eṣ-ṣobḥ.

This is a very important pronunciation pattern in Arabic.
