برنامج الحفل واضح، ومخطط الجلوس جاهز.

Because this is a nominal sentence in Arabic. In the present tense, Arabic often says X clear or Y ready without using a word for is.

So:

• برنامج الحفل واضح = The event program is clear
• مخطط الجلوس جاهز = The seating plan is ready

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

• كان برنامج الحفل واضحًا = The event program was clear
• سيكون مخطط الجلوس جاهزًا = The seating plan will be ready

It has two main parts:

1. برنامج الحفل = the program of the ceremony/event
2. واضح = clear

Grammatically:

• برنامج الحفل is the subject
• واضح is the predicate

So the structure is:

• [subject] + [predicate adjective]

Very literally:

• Program of the event — clear

Because it is an iḍāfa construction, often called a genitive/possessive construction.

In برنامج الحفل:

• برنامج = program
• الحفل = the ceremony / the event / the party

Together, they mean:

• the program of the event
• more naturally in English: the event program

Important things about iḍāfa:

• The first noun usually does not take ال
• The second noun often shows definiteness
• If the second noun is definite, the whole phrase is definite

So برنامج الحفل is definite because الحفل is definite.

That is normal in an iḍāfa construction.

In iḍāfa:

• the first noun usually appears without ال
• the second noun determines whether the whole phrase is definite or indefinite

Compare:

• برنامجُ حفلٍ = a program of an event / an event program (indefinite)
• برنامجُ الحفلِ = the program of the event (definite)

So even though برنامج has no ال, the phrase برنامج الحفل is still definite.

Yes, but more specifically it is a predicate adjective.

There are two useful ideas to separate:

1. Attributive adjective: directly describes a noun inside a noun phrase

   • البرنامج الواضح = the clear program

2. Predicate adjective: comes as the predicate of a sentence

   • البرنامج واضح = the program is clear

In your sentence, واضح is not part of the noun phrase برنامج الحفل. It is the predicate of the whole clause.

Because برنامج is a masculine singular noun, so the predicate adjective matches it in gender and number.

• برنامج = masculine singular
• واضح = masculine singular form of clear

If the subject were feminine singular, you would use واضحة:

• الخطة واضحة = The plan is clear

So the agreement here is normal:

• برنامج ... واضح
• مخطط ... جاهز

و means and.

It connects the second clause to the first:

• برنامج الحفل واضح
• ومخطط الجلوس جاهز

So the full sentence is:

• The event program is clear, and the seating plan is ready.

Notice that Arabic often uses و very freely to join words, phrases, and whole clauses.

It literally means something like:

• plan/diagram of seating
• seating plan

Breakdown:

• مخطط = plan, diagram, layout
• الجلوس = the sitting / seating

So مخطط الجلوس is another iḍāfa phrase, just like برنامج الحفل.

Natural English translations could be:

• the seating plan
• the seating chart
• the seating layout

The best translation depends on context.

Because Arabic often uses a verbal noun (called a maṣdar) where English might use a noun like seating.

• جلس = to sit
• جلوس = sitting / seating

So مخطط الجلوس means the plan of seating.

Arabic could use other wording in other contexts, but الجلوس is perfectly natural here because it refers to the arrangement or act of seating people, not just to the chairs themselves.

جاهز is a very common word meaning ready, prepared, or set.

So:

• مخطط الجلوس جاهز = The seating plan is ready

It is a straightforward and natural choice. Like واضح, it is a predicate adjective agreeing with a masculine singular subject:

• مخطط = masculine singular
• جاهز = masculine singular

If the noun were feminine, you would often see:

• الخطة جاهزة = The plan is ready

Yes, in fully vocalized formal Arabic, there would be case endings.

You could analyze it like this:

• برنامجُ الحفلِ واضحٌ
• ومخططُ الجلوسِ جاهزٌ

Explanation:

• برنامجُ: nominative, because it is the subject
• الحفلِ: genitive, because it is the second term of iḍāfa
• واضحٌ: nominative as the predicate
• مخططُ: nominative, subject
• الجلوسِ: genitive in iḍāfa
• جاهزٌ: nominative predicate

In everyday printing and most modern texts, these short vowels are omitted.

This is mostly a punctuation choice.

Arabic punctuation in modern writing often follows patterns similar to European punctuation, but usage can vary. A comma before و may be used when the writer wants to clearly separate two related clauses:

• برنامج الحفل واضح، ومخطط الجلوس جاهز.

You may also see Arabic sentences joined by و with no comma at all, especially in shorter or simpler writing. So the comma is not the core grammar here; it is mainly about style and clarity.

Yes, but the original order is the most neutral and natural here.

Current order:

• برنامج الحفل واضح
• مخطط الجلوس جاهز

This is the standard nominal-sentence pattern:

• subject + predicate

Arabic can sometimes move parts around for emphasis, but for a learner, this version is the best one to treat as basic and normal.

A simple pronunciation guide is:

• barnāmaju l-ḥafli wāḍiḥ, wa-mukhaṭṭaṭu l-julūsi jāhiz

If you want a more everyday reading without full case endings, many learners say something closer to:

• barnāmaj il-ḥafl wāḍiḥ, wa-mukhaṭṭaṭ il-julūs jāhiz

A few notes:

• ح in الحفل is a deeper h sound than English h
• ض in واضح is an emphatic consonant
• ط in مخطط is also emphatic
• ج in MSA is usually taught as j as in judge

It can vary by context.

حفل can refer to:

• a ceremony
• a party
• a celebration
• an event

So برنامج الحفل could be translated as:

• the ceremony program
• the event program
• the program for the celebration

If the meaning has already been provided to the learner, that context determines the best English choice. Grammatically, though, the Arabic structure stays the same.
