الموعد الساعة ستة.

A rough pronunciation is:

el-mawʿed es-saʿa sitta

A few useful notes:

• الساعة is pronounced es-saʿa, not el-saʿa, because س is a sun letter, so the l sound of ال assimilates.
• ستة is usually pronounced sitta in Egyptian.
• The letter ع in الموعد and الساعة is a throat sound that has no exact English equivalent.

Also, in everyday Egyptian, many speakers would more naturally use الميعاد instead of الموعد.

Because Arabic usually leaves out is/are in the present tense.

So:

• الموعد الساعة ستة = The appointment is at six

This kind of sentence is very normal in Arabic. English needs is, but Arabic does not.

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

• كان الموعد الساعة ستة = The appointment was at six.
• In Egyptian: هيكون الموعد الساعة ستة = The appointment will be at six.

Here الساعة is part of the standard way of saying a clock time.

Literally, الساعة means the hour / the clock, but in sentences like this it functions as:

• الساعة خمسة = five o’clock
• الساعة ستة = six o’clock
• الساعة سبعة = seven o’clock

So in الموعد الساعة ستة, the phrase الساعة ستة means at six o’clock.

Because both are definite forms:

• الموعد = the appointment
• الساعة = literally the hour / the clock, used in the fixed time expression

In English, having two the words close together can feel odd, but in Arabic this is normal. You should think of الساعة ستة as one time expression rather than translating each word separately.

Usually, no.

In this kind of sentence, Arabic commonly says the time directly:

• الموعد الساعة ستة

That is perfectly normal.

You may sometimes see or hear في الساعة ستة, especially in more formal Arabic or in other sentence types, but in everyday Egyptian, الساعة + time is very common on its own.

By itself, الساعة ستة means six o’clock, but it does not tell you whether it is morning or evening. Context usually makes that clear.

If you want to specify, you can add:

• الصبح = in the morning
• بالليل = at night
• مساءً = in the evening

For example:

• الموعد الساعة ستة الصبح = The appointment is at 6 AM.
• الموعد الساعة ستة بالليل = The appointment is at 6 PM / at night.

It is understandable, but in everyday Egyptian many people would more naturally say:

• الميعاد الساعة ستة

That is because ميعاد is a very common Egyptian word for appointment / set time.

So:

• الموعد الساعة ستة = understandable, a bit more standard
• الميعاد الساعة ستة = very natural in Egyptian speech

You might also hear:

• ميعادنا الساعة ستة = Our appointment is at six.

They are very close in meaning, but the feel is a little different:

• الموعد often sounds more standard or formal
• الميعاد is extremely common in everyday Egyptian Arabic

A learner should recognize both. If your focus is spoken Egyptian, ميعاد / الميعاد is especially useful.

You keep the same structure and change the time expression:

• الموعد الساعة خمسة = The appointment is at five.
• الموعد الساعة سبعة = The appointment is at seven.
• الموعد الساعة ستة ونص = The appointment is at six thirty.
• الموعد الساعة ستة والربع = The appointment is at six fifteen.
• الموعد الساعة ستة إلا ربع = The appointment is at five forty-five.

This pattern is very productive and useful in everyday conversation.

The letter ع is one of the hardest Arabic sounds for English speakers.

A good beginner approach:

• know that it is a throat sound
• do not turn it into a normal English vowel
• do not replace it with g, k, or a strong stop
• try to make a brief constricted sound in the throat

There is no exact English sound for it, so at first an approximation is fine. The most important thing is to hear it and know it is there. With listening and repetition, your pronunciation will improve.
