ناقشنا المسالة.

A common Egyptian-style pronunciation would be naʔašna el-masʔala.

A few useful notes:

• ق is often pronounced as a glottal stop ʔ in Egyptian Arabic.
• ال is usually pronounced el- in Egyptian, not al-.
• The more careful Standard Arabic pronunciation would be closer to nāqašnā al-masʔala.

Also, the standard spelling is usually المسألة with a hamza.

It is understandable in Egyptian, but it sounds a bit formal or educated rather than very casual everyday speech.

In everyday Egyptian, people might also say things like:

• اتكلمنا في الموضوع
• ناقشنا الموضوع

So ناقشنا المسألة is fine, but it has a more formal tone than very casual conversation.

ناقشنا is a verb in the past tense meaning we discussed.

It can be broken down like this:

• ناقش = discussed
• -نا = we

So the subject we is already built into the verb.

Because Arabic verbs often include the subject inside the verb itself.

So:

• ناقشنا already means we discussed

You can add إحنا for emphasis:

• إحنا ناقشنا المسألة

But it is not necessary. The sentence is complete without it.

المسألة can mean several related things depending on context, such as:

• the issue
• the matter
• the problem
• sometimes the question

In many contexts, it is better understood as issue/matter rather than a spoken question that someone asks. For an ordinary verbal question, سؤال is often more common.

ال is the Arabic definite article, meaning the.

So:

• مسألة = an issue / a matter
• المسألة = the issue / the matter

In Egyptian pronunciation, ال is usually said as el-, so المسألة is commonly pronounced el-masʔala.

The standard spelling is المسألة.

The version المسالة leaves out the hamza ء. You may see that in casual typing, but the correct spelling in careful Arabic is المسألة.

So if you are learning to write properly, use:

• ناقشنا المسألة

Starting with the verb is very normal in Arabic, especially in formal styles.

So:

• ناقشنا المسألة = literally discussed-we the-issue

This is a natural Arabic structure. Arabic often allows more flexibility in word order than English.

You could also say:

• إحنا ناقشنا المسألة

That puts extra focus on we, but the original version is perfectly normal.

Yes. That final ة is called taa marbuuTa. It often marks a feminine noun.

So مسألة is grammatically feminine. That does not change the verb here, because the subject of the verb is we, not the issue.

But the feminine gender can matter in other places, such as adjective agreement.

In Egyptian Arabic, a common negative form would be:

ما ناقشناش المسألة

This is the usual Egyptian pattern:

• ما ... ش

So:

• ناقشنا المسألة = we discussed the issue
• ما ناقشناش المسألة = we did not discuss the issue

That negative pattern is very common in spoken Egyptian Arabic.
