عندنا ضيوف كتير النهارده.

A natural word-by-word breakdown is:

• عندنا = we have / at our place / with us
• ضيوف = guests
• كتير = many / a lot of
• النهارده = today

So the whole sentence means something like:

• We have a lot of guests today
• There are many guests at our place today

Depending on context, all of these are natural English translations.

In Egyptian Arabic, possession is often expressed without a separate verb like English have.

Instead, Arabic commonly uses عند, which literally gives the sense of at or with someone.

So:

• عندنا literally = at us / with us
• but naturally it means we have

This is very common in spoken Arabic.

Examples:

• عندي عربية = I have a car
• عندك وقت؟ = Do you have time?
• عندهم مشكلة = They have a problem

So عندنا ضيوف literally feels like There are guests with us / at our place, but idiomatically it means We have guests.

عندنا has two parts:

• عند = at / with
• ـنا = us / our / we attached as a suffix

So:

• عندي = I have
• عندك = you have
• عنده = he has
• عندها = she has
• عندنا = we have
• عندهم = they have

This suffix system is very important in Egyptian Arabic.

ضيوف is the plural of ضيف (guest).

This is an example of a broken plural, which is very common in Arabic. That means the plural is not made by simply adding an ending like English -s. Instead, the word changes internally.

• ضيف = guest
• ضيوف = guests

You just need to learn many of these as vocabulary items.

In Egyptian Arabic, words meaning many / much / a lot often come after the noun.

So:

• ضيوف كتير = many guests
• literally: guests many

This is normal Arabic word order.

Compare:

• ناس كتير = many people
• فلوس كتير = a lot of money
• حاجات كتير = many things

So even though English says many guests, Egyptian Arabic naturally says guests many.

In this kind of everyday Egyptian Arabic usage, كتير usually stays the same.

So you commonly hear:

• رجالة كتير = many men
• ستات كتير = many women
• ضيوف كتير = many guests

You do not normally need to make it match the noun the way some other adjectives do.

Also, كتير can mean:

• many
• much
• a lot
• sometimes very, depending on context

Here it clearly means many / a lot of.

Yes, النهارده is a very common Egyptian Arabic word meaning today.

It is specifically colloquial Egyptian. In Modern Standard Arabic, today is usually:

• اليوم

So:

• Egyptian: النهارده
• MSA: اليوم

You may also see Egyptian spellings like:

• النهاردة

Both represent the same word in everyday writing.

A common pronunciation is roughly:

ʿandena ḍyūf kitīr ennaharda

A more learner-friendly approximation: an-de-na dyoof ke-teer en-na-har-da

A few notes:

• ع at the start of عندنا is a deep throat sound with no exact English equivalent.
• ض in ضيوف is an emphatic consonant; many learners first approximate it as a heavy d sound.
• النهارده is often pronounced smoothly in fast speech, almost like one chunk.

If you cannot produce every sound perfectly yet, that is normal.

Yes. This is a completely normal sentence in Egyptian Arabic.

Arabic often uses verbless sentences in the present tense. English needs is/are, but Arabic often does not.

In this case:

• عندنا ضيوف كتير النهارده is fully complete and natural.

You do not need to add a present-tense to be verb.

Yes, but the original order is very natural.

Original:

• عندنا ضيوف كتير النهارده

This is a straightforward, neutral way to say it.

You might also hear:

• النهارده عندنا ضيوف كتير = Today we have many guests
• عندنا النهارده ضيوف كتير = also possible, with today placed earlier for emphasis

The meaning stays basically the same, but the focus can shift slightly depending on what the speaker wants to emphasize.

It can mean several nearby ideas, depending on context:

• We have many guests today
• There are many guests at our place today
• We’re having lots of visitors today

Most often, a listener will understand it as something like at our home / with our family / where we are. But عندنا does not always have to mean only in our house. It can also mean with us, on our side, or in our situation, depending on context.

Here, though, at our place is probably the most natural interpretation.
