اذا الاستمارة الرسمية طويلة، عبي اول صفحة هلا والصفحات التانية بعدين.

In Arabic, the present tense usually does not use a separate verb for to be.

So:

• الاستمارة الرسمية طويلة
• literally: the official form long
• natural English: the official form is long

This is completely normal in both Levantine and Standard Arabic.

If you wanted a past meaning, then Arabic would use a verb, for example كانت = was.

اذا here means if.

So the first part:

• اذا الاستمارة الرسمية طويلة
• if the official form is long

In Levantine, اذا is a very common way to introduce a real or possible condition.

A useful comparison:

• اذا = if / whenever for a real possibility
• لو = often if for more hypothetical or unreal situations

In speech, many Levantine speakers pronounce إذا like iza or eza.

Because الاستمارة is a feminine noun.

In Arabic, adjectives agree with the noun they describe in:

• gender
• number
• definiteness

So:

• الاستمارة = the form (feminine, definite)
• الرسمية = the official (feminine, definite)
• طويلة = long (feminine singular)

Notice something important:

• الرسمية has الـ because it directly describes the definite noun الاستمارة
• طويلة does not have الـ because it is the predicate of the sentence, not part of the noun phrase

That is why Arabic says:

• الاستمارة الرسمية طويلة
• not الاستمارة الرسمية الطويلة if the meaning is the official form is long

عبي is an imperative, meaning fill or fill out.

In this sentence it means:

• عبي اول صفحة
• fill out the first page

This is very natural Levantine wording for forms, applications, and similar paperwork.

It comes from the verb عبّى / يعبّي, which has the basic idea of filling something. In bureaucratic contexts, it commonly means fill in / fill out.

So:

• عبي الاستمارة = fill out the form

Yes. عبي is the command form used to speak to one person.

In context, it means:

• Fill out the first page now...

In colloquial Levantine, imperative forms can vary a bit by region and by how carefully someone is speaking, but here the basic idea is clearly a command or instruction to a single listener.

Because in Levantine, أول + noun is a very common everyday way to say the first ...

So:

• اول صفحة = the first page

This is more colloquial and natural in speech.

A more formal or Standard Arabic-style version would often be:

• الصفحة الأولى

Both mean the same thing, but:

• اول صفحة sounds more conversational
• الصفحة الأولى sounds more formal or written

هلا means now or right now in Levantine.

So:

• عبي اول صفحة هلا
• fill out the first page now

It is a very common colloquial time word.

Depending on the region, you may also hear related pronunciations like:

• هلق
• هلّق
• هلا

They all mean roughly now.

Do not confuse this with other dialect uses of hala that can mean welcome.

Literally, التانية can mean the second.

But in this sentence, with a plural noun, الصفحات التانية is understood as:

• the other pages
• the remaining pages
• the rest of the pages

So the sentence is not saying only page number two. It means the pages after the first one.

That is very natural colloquial usage.

A more explicit wording could be something like:

• الصفحات الباقية = the remaining pages
• الصفحات الأخرى = the other pages

But الصفحات التانية is common and idiomatic in speech.

Because Arabic, like English, often leaves out a repeated verb when it is understood from context.

The full idea is:

• عبي اول صفحة هلا وعبّي الصفحات التانية بعدين

But the second عبي is omitted because it is obvious.

So this part:

• والصفحات التانية بعدين

really means:

• and fill out the other pages later

This kind of omission is very common in everyday speech.

بعدين means later or afterwards.

So:

• هلا = now
• بعدين = later

Together they create a very natural contrast:

• عبي اول صفحة هلا والصفحات التانية بعدين
• fill out the first page now and the other pages later

That is extremely normal in Levantine Arabic.

This sentence mixes:

• colloquial grammar and vocabulary:
  • عبي
  • هلا
  • التانية
  • بعدين
• more formal or semi-formal vocabulary:
  • الاستمارة
  • الرسمية

Native speakers do this all the time, especially when talking about official documents, school, work, government forms, and similar topics. The topic itself is formal, but the spoken sentence is still dialectal.

So this kind of register mixing is not strange at all; it is actually very realistic.

The word order here is very natural, but Arabic has some flexibility.

Given sentence:

• عبي اول صفحة هلا والصفحات التانية بعدين

This places the time words after each object phrase:

• the first page now
• the other pages later

That sounds smooth and conversational.

You might also hear slightly different arrangements in speech, depending on emphasis, but this version is very idiomatic and easy to understand. It especially highlights the contrast between now and later.
