الاجتماع هيبدا بعد دقيقة.

A natural pronunciation is:

el-egtimāʿ hayebda baʿd daʾīʔa

Very roughly for an English speaker:

• الاجتماع = el-egtimāʿ
• هيبدا = ha-yebda or he-yebda
• بعد = baʿd
• دقيقة = daʾīʔa

A few notes:

• The ج in Egyptian Arabic is usually pronounced like g in go, so الاجتماع sounds like el-igtimaaʿ / el-egtimaaʿ, not like MSA-style ij...
• The ع in اجتماع and بعد is a consonant English does not have, so learners often just approximate it at first.
• The ق in دقيقة is often pronounced as a glottal stop in Egyptian Arabic, so it sounds like daʔīʔa.

هيبدا is the future form of start / begin.

It breaks down like this:

• هـ / حـ = future marker, like will / going to
• يبدأ in colloquial spelling/pronunciation = yebda = he/it starts

So:

• هيبدا = it will start

In more careful spelling, you may also see هيبدأ or حيبدأ.

No. This is a very common confusion.

In هيبدا, the first part is هـ (or حـ) as a future marker, not the separate pronoun هي.

So this is not:

• هي
  • بدا

It is:

• هـ
  • يبدأ

In other words, هيبدا means will start, not she started or anything involving the pronoun she.

Because يـ is the normal imperfect/present marker for he/it in Arabic.

الاجتماع is a singular masculine noun, so the verb takes the he/it form:

• يبدأ = it starts
• هيبدأ = it will start

So even though English says the meeting will start, Arabic uses the same verb form as it will start.

Because بيبدأ is the regular present/habitual form, while هيبدا is the future form.

In Egyptian Arabic:

• بيبدأ = it starts / it is starting / it usually starts
• هيبدأ = it will start

A useful pattern is:

• present: بيـ...
• future: هـ... or حـ...

So the بـ is not used here because the sentence is talking about the future.

Because Egyptian Arabic very often uses subject + verb word order in everyday speech.

So:

• الاجتماع هيبدا بعد دقيقة = very natural colloquial Egyptian

You could also hear:

• هيبدأ الاجتماع بعد دقيقة

That is also understandable and natural, but the version with the subject first is extremely common in spoken Egyptian Arabic.

Literally, بعد دقيقة means after a minute, but in this kind of context it is commonly understood as in a minute.

So in natural English:

• The meeting will start in a minute

Word by word:

• بعد = after
• دقيقة = a minute

Arabic often uses بعد + time expression in this way.

Because it means a minute, not the minute.

• دقيقة = a minute
• الدقيقة = the minute

Since the sentence is talking about one unspecified minute from now, the indefinite form is the normal choice.

It is Egyptian Arabic.

The clearest sign is هيبدا, which is a colloquial future form.

In Modern Standard Arabic, you would expect something like:

• سيبدأ الاجتماع بعد دقيقة or
• سوف يبدأ الاجتماع بعد دقيقة

So the idea is the same, but the wording here is specifically Egyptian colloquial.

Because it refers to the meeting, not just a meeting.

• اجتماع = a meeting
• الاجتماع = the meeting

In many real-life contexts, the speaker and listener already know which meeting is meant, so the definite form is natural.

Because colloquial Arabic spelling is less fixed than MSA spelling.

You may see:

• هيبدا
• هيبدأ
• حيبدا
• حيبدأ

These reflect:

• different ways of writing the future marker (ه or ح)
• whether the writer includes the hamza in يبدأ

All of these point to the same spoken Egyptian form: will start.

A few natural variants are:

• الاجتماع حيبدأ بعد دقيقة
• هيبدأ الاجتماع بعد دقيقة
• الاجتماع هيبدأ كمان دقيقة
• الاجتماع هيبدأ بعد دقيقة واحدة

They all stay close in meaning, though some sound a little more casual or a little more explicit than others.

A natural negated version is:

• الاجتماع مش هيبدا بعد دقيقة

This means:

• The meeting won’t start in a minute

Here:

• مش = not
• هيبدا = will start

So مش goes before the future verb phrase in this kind of sentence.
