المشكلة بتبان بسيطة.

A good approximate pronunciation is el-moshkela betbān basīṭa.

A rough stress pattern is:

el-mosh-KE-la bet-BAAN ba-SEE-ta

Notes:

• ال is usually pronounced el- in Egyptian Arabic.
• بتبان has a long ā sound in the second syllable.
• بسيطة ends with the feminine -a sound.

Here is the breakdown:

• المشكلة = the problem
• بتبان = seems / appears / looks
• بسيطة = simple

So structurally, it is:

the problem + seems + simple

Here, بتبان means seems, appears, or looks.

The basic idea of the verb is to appear / become apparent / seem.
Because it is followed by بسيطة, the meaning is not physical appearance only. It means:

• the problem seems simple
• the problem looks simple
• the problem appears simple

That beginning combines two things:

• بـ = a common Egyptian marker for the present/non-past
• تـ = the person/gender marker for she/it

Since المشكلة is a feminine noun, the verb agrees with it using the تـ form.

So بتبان is basically the Egyptian present form meaning it seems / it appears for a feminine singular subject.

Because مشكلة is a grammatically feminine noun in Arabic.

One clue is the ending ـة. Many nouns ending in ـة are feminine.

Since المشكلة is feminine, words connected to it often show feminine agreement, including:

• the verb: بتبان
• the adjective: بسيطة

Because adjectives agree with the nouns they describe.

Since المشكلة is feminine singular, the adjective must also be feminine singular:

• masculine: بسيط
• feminine: بسيطة

So بسيطة matches المشكلة.

In Arabic, the present-tense verb to be is usually not said.

So Arabic often says the equivalent of:

• the problem simple = the problem is simple

In this sentence, though, you also have بتبان, which already gives the idea of seems/appears. So you do not need a separate word for is.

The difference is in certainty and nuance.

• المشكلة بسيطة = The problem is simple.
• المشكلة بتبان بسيطة = The problem seems simple.

So بتبان makes the statement less direct. It suggests appearance or first impression, not a firm fact.

Because it is describing how the problem seems.

In English, we also do this:

• The problem seems simple

Here, simple comes after seems.
Arabic works similarly in this sentence. بسيطة is not directly sitting next to المشكلة as a normal noun-adjective pair; instead, it is the description that follows بتبان.

In Egyptian Arabic, starting with the subject is very common in everyday speech.

So:

• المشكلة بتبان بسيطة

feels natural and conversational: As for the problem, it seems simple.

Arabic can often allow different word orders, but this subject-first order is very normal in spoken Egyptian.

Yes, بتبان is a very Egyptian-style form.

In Standard Arabic, a common equivalent would be:

• تبدو المشكلة بسيطة or
• المشكلة تبدو بسيطة

The meaning is very similar, but the verb changes:

• Egyptian: بتبان
• Standard Arabic: تبدو

Yes. The same verb can be used for something literally becoming visible.

For example, in another sentence it could mean:

• The moon appears
• The building becomes visible

But in المشكلة بتبان بسيطة, because it is followed by بسيطة, the meaning is clearly seems / looks simple, not literal visibility.

Yes. In this sentence, looks simple is a very natural translation.

Depending on context, all of these can work:

• seems simple
• looks simple
• appears simple

Looks is especially natural in everyday English.

A natural negative version is:

المشكلة ما بتبانش بسيطة

This means:

The problem doesn't seem simple.

This uses the common Egyptian negation pattern:

• ما ... ش

wrapped around the verb:

• بتبان → ما بتبانش
