لازم املا الاستمارة قبل الاجتماع.

A natural pronunciation is:

lazem amla l-estemāra abl el-egtimāʿ

A few notes:

• لازم = lazem
• املا = amla
• الاستمارة is often heard as l-estemāra in connected speech
• قبل = abl
• الاجتماع = el-egtimāʿ

In Egyptian Arabic, ج is usually pronounced like g in go, so اجتماع sounds like egtimāʿ, not ijtimāʿ.

لازم expresses necessity or obligation. It often means:

• must
• have to
• need to

So لازم املا means I have to fill out or I must fill out.

A useful pattern is:

لازم + imperfect verb

Examples:

• لازم أروح = I have to go
• لازم نخلص = we have to finish
• لازم تذاكر = you have to study

Because the verb already shows the subject.

In املا, the prefix أ- marks I in the imperfect verb. So املا means I fill / I will fill / I have to fill, depending on context.

You can add أنا if you want emphasis:

• أنا لازم املا الاستمارة قبل الاجتماع

But it is not necessary.

That is a very common learner question.

In Egyptian Arabic, the prefix بـ often marks the normal present or habitual:

• بملا الاستمارة كل يوم = I fill out the form every day

But after words like لازم, Egyptian usually uses the bare imperfect without بـ:

• لازم املا
• not usually لازم بملا

So after لازم, dropping بـ is the normal pattern.

In this sentence, it means I fill / I should fill / I have to fill.

But in casual Arabic spelling, املا can look ambiguous, because short vowels are not written. So the same spelling could represent:

• amla = I fill
• imla = fill! (to one man)

Context tells you which one is meant.

Here, after لازم, it clearly means amla = I have to fill.

In informal or dialect writing, people often leave out some hamza spelling details.

So املا is commonly written instead of a more careful spelling like أملا.

This is very normal in Egyptian Arabic writing online, in texts, and in informal notes. Learners should get used to the fact that colloquial spelling is often less strict than Modern Standard Arabic spelling.

استمارة means form or application form.

The prefix الـ means the, so:

• استمارة = a form / form
• الاستمارة = the form

So املا الاستمارة literally means fill the form.

In English, this is often translated as fill out the form.

It is a simple time expression:

• قبل = before
• الاجتماع = the meeting

So:

قبل الاجتماع = before the meeting

This is a very common structure:

قبل + noun

Examples:

• قبل الشغل = before work
• قبل الدرس = before the lesson
• قبل السفر = before traveling / before the trip

Because Egyptian Arabic changes the pronunciation of some letters.

The big one here is ج:

• In Modern Standard Arabic, اجتماع is closer to ijtimāʿ
• In Egyptian Arabic, it is usually egtimāʿ

So a learner may hear:

• el-egtimāʿ in Egyptian
• al-ijtimāʿ in Standard Arabic

The spelling stays the same, but the pronunciation changes.

Yes, but the more standard version would usually be:

يجب أن أملأ الاستمارة قبل الاجتماع

or

لا بد أن أملأ الاستمارة قبل الاجتماع

Your original sentence is natural Egyptian Arabic:

لازم املا الاستمارة قبل الاجتماع

It is very common in speech and informal writing.
