هو يعيد الحجز.

Because Arabic verbs already include subject information, يعيد by itself can mean he repeats / he is repeating / he redoes.

So هو is not strictly necessary. It is often added for:

• emphasis
• clarity
• contrast with someone else

So:

• يعيد الحجز = He is redoing/repeating the booking
• هو يعيد الحجز = He is the one redoing/repeating the booking

In many contexts, dropping هو would sound more neutral.

It is usually analyzed as a nominal sentence because it begins with هو.

• هو = the subject of the sentence
• يعيد الحجز = the predicate, which happens to be a verbal phrase

If you said يعيد الحجز, that would be a more straightforward verbal sentence.

So both are possible, but they have slightly different feel:

• يعيد الحجز = more neutral, action-focused
• هو يعيد الحجز = more explicit or slightly emphatic about he

يعيد is in the imperfect form.

In Arabic, the imperfect can express several ideas depending on context, including:

• present: he repeats / he is repeating
• habitual: he usually repeats
• near future: he will repeat

So without more context, يعيد does not map to just one English tense.

If you want a clearer future meaning, Arabic often uses:

• سيعيد
• سوف يعيد

يعيد comes from the verb أعاد, which means to repeat, to do again, or to restore/return something depending on context.

This is important because learners often confuse it with يعود.

Compare:

• أعاد - يعيد = to repeat / to do again / to restore something
• عاد - يعود = to return / come back

So:

• هو يعيد الحجز = He repeats / redoes the booking
• هو يعود = He returns / comes back

Even though the verbs are related historically, they are not the same verb.

الحجز is the direct object of يعيد.

The verb أعاد / يعيد is transitive here, so it takes something that is being repeated or redone. That thing is الحجز.

In fully vocalized formal Arabic, the direct object would be in the accusative case:

• الحجزَ

But in normal unvocalized writing, you usually just see:

• الحجز

So the case is there grammatically, even if it is not written.

الـ is the Arabic definite article, equivalent to the.

So الحجز means the booking / the reservation / the detention, depending on context.

If the noun were indefinite, you would expect something like:

• حجزًا in fully vocalized form

But here it is definite: the specific booking/reservation already known from context.

A careful pronunciation is:

huwa yuʿīdu al-ḥajza

A few notes:

• هو = huwa
• يعيد = yuʿīdu
• الحجز = al-ḥajz(a)

Important sounds:

• ع in يعيد is the letter ʿayn, a deep throat sound with no exact English equivalent
• ح in الحجز is a strong breathy ḥ, not the normal English h
• ج in Modern Standard Arabic is usually pronounced like the j in judge

Also, ح is a moon letter, so الـ is pronounced clearly as al-:

• al-ḥajz not an assimilated form

Yes, absolutely.

In fact, يعيد الحجز is often the more natural default if you do not need emphasis.

Use هو when you want to:

• make the subject explicit
• emphasize he
• contrast him with someone else

For example:

• يعيد الحجز = neutral
• هو يعيد الحجز = He is redoing the booking
• possible implied contrast: not someone else

No. الحجز can have several meanings depending on context, such as:

• booking
• reservation
• detention
• seizure
• blocking

So this word can be a little tricky by itself. The surrounding context tells you which meaning is intended.

Since the meaning has already been given to the learner, the main thing to remember is that الحجز is a noun and its exact English translation depends on context.

Because in Arabic, you usually do not use a present-tense form of to be the way English does.

Arabic does not normally insert a present-tense is/am/are in this kind of sentence.

So:

• هو يعيد الحجز does not need a word for is
• the meaning He is redoing the booking is understood from the structure and context

This is a very common difference between English and Arabic.
