الاجتماع الساعة تلاتة.

A good pronunciation is:

el-egtimāʿ es-sāʿa talāta

A few useful notes:

• ج in Egyptian Arabic is usually pronounced like g in go, so اجتماع sounds like egtimāʿ, not ijtimāʿ.
• الساعة is pronounced es-sāʿa, not el-sāʿa, because س is a sun letter, so the l of ال assimilates.
• The letter ع in اجتماع and الساعة is a throat sound that English does not have. It is normal if that takes time to learn.

Because Arabic often leaves out the present-tense verb to be.

So where English says:

• The meeting is at three

Egyptian Arabic can simply say:

• الاجتماع الساعة تلاتة

This is completely normal. In the present tense, Arabic often uses a verbless sentence.

Literally, الساعة means the clock or the hour, but in everyday Egyptian Arabic it is the normal way to introduce a clock time.

So:

• الساعة تلاتة = three o’clock
• الساعة خمسة = five o’clock

In English, we use at before a time. In Egyptian Arabic, الساعة often does that job in expressions like this.

Because this sentence is in Egyptian Arabic, not formal Standard Arabic.

In Egyptian:

• ث is often pronounced as t
• so ثلاثة becomes تلاتة

That is why learners will often hear and see:

• تلاتة
• اتنين
• تمانية

instead of the more formal Standard Arabic forms.

This is a very common question.

In Egyptian Arabic, when telling the time, people usually use the cardinal number:

• الساعة تلاتة
• الساعة أربعة
• الساعة خمسة

In Modern Standard Arabic, telling time usually uses the feminine ordinal:

• الساعة الثالثة
• الساعة الرابعة

So الساعة تلاتة is correct and natural for Egyptian Arabic.

They have الـ for different reasons:

• الاجتماع = the meeting
  Here, الـ makes the noun definite.

• الساعة in time expressions is part of the normal phrase used to say clock times.
  So الساعة تلاتة is the regular way to say three o’clock.

So even though both words have الـ, they are not doing exactly the same job in the sentence.

No.

• الاجتماع → el-egtimāʿ
  The l is pronounced.

• الساعة → es-sāʿa
  The l is not pronounced because س is a sun letter.

So the pronunciation changes depending on the first consonant of the next word.

Usually, learners should not drop الساعة when giving a clock time.

• Natural: الاجتماع الساعة تلاتة
• Less natural / unclear for learners: الاجتماع تلاتة

Without الساعة, it may sound incomplete or confusing. If you mean at three o’clock, keep الساعة.

By default, it usually means at three o’clock.

But in real conversation, exactness depends on context, just like in English. If you want to be clearer:

• الاجتماع الساعة تلاتة بالظبط = the meeting is at exactly 3:00
• الاجتماع حوالي الساعة تلاتة = the meeting is around 3:00

So the plain sentence normally means 3 o’clock, but context matters.

You can add a time-of-day expression after the number.

For example:

• الاجتماع الساعة تلاتة العصر = the meeting is at 3 PM
• الاجتماع الساعة تلاتة بعد الضهر = the meeting is at 3 in the afternoon
• الاجتماع الساعة تلاتة الفجر = the meeting is at 3 AM
• الاجتماع الساعة تلاتة الصبح = the meeting is at 3 in the morning

In everyday Egyptian Arabic, people often prefer these expressions over saying AM and PM.

It is specifically colloquial Egyptian Arabic in its current form.

The clearest clue is تلاتة, which is colloquial. A more Standard Arabic version would usually be something like:

• الاجتماع الساعة الثالثة
• or الاجتماع في الساعة الثالثة

So if you say الاجتماع الساعة تلاتة, people will hear it as dialectal, natural spoken Arabic, especially Egyptian.

Yes, very natural.

Starting with الاجتماع makes the meeting the topic, and then الساعة تلاتة gives the time.

So the structure is basically:

• الاجتماع = topic
• الساعة تلاتة = comment about it

This kind of order is very common in Arabic. It is short, direct, and natural in conversation.
