الزميلة بتشرح لي المشكلة تاني.

الزميلة means the female colleague or the woman coworker/classmate.

The ending ـة is a very common marker of feminine nouns in Arabic. So:

• زميل = male colleague
• زميلة = female colleague

The الـ at the beginning means the, so الزميلة = the female colleague.

In Egyptian Arabic, the prefix بـ is commonly used with the present tense to describe habitual, ongoing, or simple present actions.

So:

• تشرح = she explains / she is explaining (more neutral or MSA-like)
• بتشرح = she explains / she’s explaining in normal Egyptian speech

In this sentence, بتشرح is the natural Egyptian form.

Because in Arabic, the present-tense verb for she often takes تـ at the beginning.

So بتشرح breaks down like this:

• بـ = Egyptian present marker
• تـ = she marker
• شرح = the root idea of explaining

So بتشرح means she explains / she is explaining.

This can confuse English speakers because تـ is also used in some forms for you, but here the subject الزميلة makes it clear that it means she.

لي here means to me.

So:

• بتشرح لي = she is explaining to me

It is made of:

• لـ = to/for
• ي = me

In fast speech and very often in writing too, this is commonly attached to the verb:

• بتشرح لي
• بتشرحلي

Both represent the same meaning.

This is a normal Arabic sentence pattern.

In English, we often say:

• She is explaining the problem to me

But in Arabic, it is very common to say:

• She is explaining to me the problem

So:

• بتشرح لي المشكلة = literally she explains to me the problem

This word order is natural in Egyptian Arabic.

المشكلة means the problem, while مشكلة means a problem.

Since the sentence uses the problem, Arabic marks that with الـ:

• مشكلة = a problem
• المشكلة = the problem

تاني here means again.

So:

• بتشرح لي المشكلة تاني = She’s explaining the problem to me again

In Egyptian Arabic, تاني is very commonly used for again or a second time.

Depending on context, تاني can also relate to second/another, but here the meaning is clearly again.

In Egyptian Arabic, تاني often comes at the end of the sentence, as it does here:

• الزميلة بتشرح لي المشكلة تاني

That is a very natural placement for again.

You may hear other word orders in conversation, but sentence-final تاني is extremely common.

A common pronunciation would be something like:

ez-zamīla bitishraḥli el-moshkila tāni

A few useful pronunciation notes:

• الزميلة is pronounced more like ez-zamīla, because ز is a sun letter, so the ل in الـ assimilates.
• بتشرح لي is often pronounced together as bitishraḥli
• المشكلة is commonly pronounced el-moshkila
• تاني sounds like tāni

This is because of sun letters and moon letters.

In الزميلة, the letter ز is a sun letter, so the ل of الـ is not pronounced separately. That is why it sounds like:

• الزميلة → ez-zamīla

In المشكلة, م is a moon letter, so the ل is pronounced:

• المشكلة → el-moshkila

This is a very common feature of Arabic pronunciation.

Yes, very often in informal writing you will see:

• بتشرح لي
• بتشرحلي

Both are common in Egyptian Arabic writing, especially in chats and messages.

The second version reflects how people actually say it in connected speech.

You would change both the noun and the verb form:

• الزميل بيشرح لي المشكلة تاني

That means The male colleague is explaining the problem to me again.

Compare:

• الزميلة بتشرح = the female colleague is explaining
• الزميل بيشرح = the male colleague is explaining

So:

• زميلة / بتشرح = feminine
• زميل / بيشرح = masculine

It is specifically Egyptian Arabic in feel, especially because of بتشرح and تاني.

In Modern Standard Arabic, you would be more likely to see something like:

• الزميلة تشرح لي المشكلة مرةً أخرى

Key differences:

• Egyptian: بتشرح
• MSA: تشرح
• Egyptian: تاني
• MSA: مرة أخرى

So the sentence you gave is very natural Egyptian Arabic.

It can mean either, depending on context.

Like many present-tense forms in Egyptian Arabic, بتشرح can cover both:

• she explains
• she is explaining

So in context, it could mean:

• a general/habitual action: She explains the problem to me again
• something happening now: She’s explaining the problem to me again

The surrounding conversation usually tells you which meaning is intended.
