قبل ما الضيوف يجوا، لازم ننضف الكنبة والسجادة.

قبل means before. In Egyptian Arabic, when before is followed by a whole action or clause, speakers very often use قبل ما + a verb.

So:

• قبل ما الضيوف يجوا = before the guests come

But with a noun, قبل by itself is enough:

• قبل العشا = before dinner

So قبل ما is a very common way to say before someone does something.

In Egyptian Arabic, بـ often marks the regular present or habitual meaning. But after قبل ما, you usually use the bare imperfect verb, not the بـ form.

So:

• بيجوا = they come / they usually come
• يجوا = come, in a dependent or future-related clause like before they come

That is why قبل ما الضيوف يجوا sounds natural here.

لازم means must, have to, or need to, depending on context.

In this sentence:

• لازم ننضف = we must clean / we need to clean

In Egyptian Arabic, لازم is commonly followed directly by an imperfect verb. There is no separate word for to like in English.

So you should think of لازم + verb as a very common pattern for obligation.

For the same basic reason as يجوا: after لازم, Egyptian Arabic normally uses the bare imperfect, not the بـ form.

Compare:

• بننضف = we are cleaning / we clean
• لازم ننضف = we need to clean

So ننضف here does not mean an ongoing present action. It means something that should be done.

Because the verb itself already shows the subject.

In ننضف, the prefix نـ tells you the subject is we. Arabic often leaves subject pronouns out when the verb already makes them clear.

So:

• ننضف = we clean / we should clean

You could add إحنا for emphasis, but it is not necessary:

• لازم إحنا ننضف = We need to clean

Normally, though, just لازم ننضف is enough.

In يجوا, the ending ـوا marks the plural subject, so the verb means they come.

Here it matches الضيوف:

• الضيوف يجوا = the guests come

So even without an English-style subject pronoun like they, the verb form already tells you it is plural.

Because الضيوف refers to people, and human plurals normally take full plural agreement.

So:

• الضيوف يجوا = the guests come

This is different from many non-human plurals in Arabic, which are often treated like feminine singular. Since guests are people, a plural verb is the normal choice.

Because they are definite: the couch and the rug.

In a sentence like this, the speaker usually means specific things in the house, not just any couch or any rug. So using الـ is natural:

• الكنبة = the couch/sofa
• السجادة = the rug/carpet

Arabic often uses definiteness in places where English would also naturally say the.

Yes. You can also say:

• لازم ننضف الكنبة والسجادة قبل ما الضيوف يجوا

That is completely natural. Putting قبل ما الضيوف يجوا at the beginning gives a little more emphasis to the time frame, like Before the guests come, ...

So both word orders work.

It is clearly Egyptian Arabic.

Some Egyptian features here are:

• يجوا for come
• لازم used in a very colloquial, everyday way
• الكنبة as a common spoken word for couch/sofa

A more Modern Standard Arabic version would be something like:

• قبل أن يأتي الضيوف، يجب أن ننظف الأريكة والسجادة.

So the sentence you have is natural everyday Egyptian, not formal textbook Arabic.

In Egyptian Arabic, ج is usually pronounced like a hard g in go, not like the j in job.

So:

• يجوا starts with a yig- sound
• السجادة has a hard g sound in the middle

Also, الـ is often pronounced more like el- or il-, and it assimilates before certain letters. So in natural speech:

• الضيوف sounds roughly like eḍ-ḍuyūf
• السجادة sounds roughly like es-segāda

You do not need perfect pronunciation right away, but it is good to know that Egyptian ج is usually a hard g.
