المشروع جاهز بحلول الصباح.

Because Arabic often uses a nominal sentence in the present tense, with no verb equivalent to is/are.

So:

• المشروع = the project
• جاهز = ready

Together, المشروع جاهز literally means the project ready, but naturally it means the project is ready.

In this sentence, the time phrase بحلول الصباح makes the whole statement understood as something like the project will be ready by morning, even though no separate verb is written.

This is a standard nominal sentence:

• المشروع is the subject of the sentence
• جاهز is the predicate describing that subject

In traditional Arabic grammar, these are:

• المشروع = مبتدأ
• جاهز = خبر

So the structure is basically:

[subject] + [predicate] + [time expression]

= المشروع + جاهز + بحلول الصباح

Because predicates in sentences like this are usually indefinite.

So Arabic says:

• المشروع جاهز = the project is ready

not usually:

• المشروع الجاهز

Because المشروع الجاهز would normally mean the ready project, where الجاهز is an adjective attached to the noun, not the main predicate of the sentence.

So:

• المشروع جاهز = a full sentence
• المشروع الجاهز = a noun phrase

Because it agrees with المشروع, which is a singular masculine noun.

Agreement here is straightforward:

• المشروع = singular, masculine
• therefore جاهز = singular, masculine

If the noun changed, the predicate would normally change too. For example:

• الخطة جاهزة = the plan is ready
  because الخطة is feminine singular

So جاهز is in the form that matches المشروع.

بحلول is an idiomatic expression meaning by the time of, by, or upon the arrival of.

It is made from:

• بـ = a preposition
• حلول = a verbal noun related to arrival/coming

So بحلول الصباح means something like:

• by morning
• by the time morning comes

This is more precise than just saying في الصباح, which means in the morning.

Compare:

• بحلول الصباح = by morning / no later than morning
• في الصباح = in the morning

الصباح comes after بحلول because it completes that expression: بحلول الصباح.

Grammatically:

• بحلول contains the preposition بـ
• حلول is followed by الصباح in an iḍāfa construction
• الصباح is therefore genitive

In fully vocalized Arabic, you would see something like:

• بِحُلولِ الصَّباحِ

So both حلول and الصباح are in the genitive here.

On its own, المشروع جاهز usually means the project is ready in the present.

But once you add بحلول الصباح, the meaning is naturally understood as future:

• the project will be ready by morning

Arabic often lets the time expression make the time reference clear, without adding an explicit future verb.

If you want to make the future extra explicit, you could say:

• سيكون المشروع جاهزًا بحلول الصباح

That means very clearly: the project will be ready by morning.

That depends on the sentence structure and whether case endings are being shown.

In this exact sentence, جاهز is the predicate of a nominal sentence, so in fully vocalized MSA it would be:

• جاهزٌ

But in normal unvowelled writing, that simply appears as جاهز.

If you use كان or سيكون, the predicate becomes accusative, so you would get:

• سيكون المشروع جاهزًا بحلول الصباح

So:

• المشروع جاهز → underlying case is nominative
• سيكون المشروع جاهزًا → accusative after يكون

Yes, absolutely.

Both are natural, but they feel slightly different:

• المشروع جاهز بحلول الصباح
  more compact; the future meaning is understood from the time phrase

• سيكون المشروع جاهزًا بحلول الصباح
  more explicit about the future

In formal writing, both are possible. The version with سيكون leaves less room for ambiguity.

No, the meanings are related but not the same.

• بحلول الصباح = by morning
  This sets a deadline or endpoint.

• في الصباح = in the morning
  This just gives the time something happens.

• قبل الصباح = before morning
  This means earlier than morning.

So if you say:

• المشروع جاهز بحلول الصباح

the idea is that by the time morning arrives, the project is ready.

It is pronounced aṣ-ṣabāḥ, not al-ṣabāḥ.

That is because ص is a sun letter, so the ل of الـ is not pronounced separately. Instead, the following consonant is doubled.

So:

• written: الصباح
• pronounced: aṣ-ṣabāḥ

This is a very common feature of Arabic pronunciation.

It is pronounced approximately al-mashrūʿ.

The final letter is ع, which is the consonant ʿayn. That sound does not exist in English, so many learners find it difficult at first.

A rough breakdown is:

• al-
• mash-
• rūʿ

The last sound should not disappear completely. Even if your ʿayn is not perfect yet, it is good to be aware that the word does not simply end as mashroo.
