المحكمة مفتوحة النهارده.

A natural Egyptian pronunciation is:

el-maḥkama maftūḥa en-naharda

A rough English-friendly guide:

• el-maḥkama = el-MAH-ka-ma
• maftūḥa = maf-TOO-ha
• en-naharda = en-na-HAR-da

A few notes:

• ḥ is a stronger, breathier h sound than English h.
• In fast speech, النهارده often sounds like ennaharda.
• Stress usually falls roughly like this: el-MAḥ-ka-ma maf-TŪ-ḥa en-na-HAR-da.

In Arabic, present-tense sentences like The court is open today usually do not use a verb meaning is/are/am.

So:

• المحكمة = the court
• مفتوحة = open
• النهارده = today

Together: المحكمة مفتوحة النهارده = The court is open today

This is very normal in both Egyptian Arabic and Modern Standard Arabic.
If you wanted the past or future, then Arabic would use other words:

• كانت المحكمة مفتوحة = The court was open
• المحكمة هتكون مفتوحة = The court will be open

Because المحكمة is a feminine noun.

In Arabic, adjectives must agree with the noun they describe. Since محكمة is feminine, the adjective also takes the feminine form:

• مفتوح = open (masculine)
• مفتوحة = open (feminine)

So:

• الباب مفتوح = The door is open
• المحكمة مفتوحة = The court is open

The ـة / -a ending often marks the feminine form.

Usually, yes. A noun ending in ـة is very often feminine, and محكمة is one of those nouns.

So learners often use this as a helpful clue:

• words ending in ـة are often feminine
• therefore their adjectives should also be feminine

That is why you get:

• المحكمة مفتوحة not
• المحكمة مفتوح

مفتوحة literally means open.

Here it describes the state of the court: it is open for business / operating / not closed.

It comes from the root ف-ت-ح, which is connected with opening:

• فتح = to open
• مفتوح / مفتوحة = open

So in this sentence, it is functioning as an adjective meaning open.

Yes. النهارده means today, and it is a very common Egyptian Arabic word.

You may also see it spelled:

• النهارده
• النهاردة

Both represent Egyptian pronunciation/spelling choices.

Compared with other varieties:

• Egyptian Arabic: النهارده
• Modern Standard Arabic: اليوم

So this sentence is clearly colloquial Egyptian, not formal written Standard Arabic.

Because that word order is very natural in Arabic.

The sentence structure is basically:

• المحكمة = subject
• مفتوحة = predicate/adjective
• النهارده = time expression

So literally it is something like:

• The court open today

Putting time expressions at the end is very common and natural.

You can sometimes move النهارده for emphasis, but the original order is simple and normal:

• المحكمة مفتوحة النهارده

Yes. النهارده المحكمة مفتوحة is also understandable and natural, especially if you want to emphasize today.

Compare:

• المحكمة مفتوحة النهارده = neutral statement
• النهارده المحكمة مفتوحة = Today, the court is open

So the sentence can be rearranged somewhat, but the original version is a very common everyday pattern.

Because ن is a sun letter.

In Arabic, when الـ comes before a sun letter, the l sound assimilates to the next consonant. So:

• underlying form: al-naharda
• actual pronunciation: an-naharda / en-naharda

In Egyptian Arabic, learners often hear it as ennaharda.

This is the same kind of thing you hear in words like:

• الشمس pronounced esh-shams
• الناس pronounced en-nās

It is a nominal sentence.

That means it starts with a noun, not a verb:

• المحكمة = the court

Then it gives information about that noun:

• مفتوحة = open
• النهارده = today

So this is a very typical Arabic nominal sentence:

• subject + predicate

There is no present-tense to be verb, which is why it may feel unusual to English speakers at first.

The most common negation would be:

المحكمة مش مفتوحة النهارده
= The court isn’t open today

Here:

• مش = not / isn’t / aren’t

So:

• مفتوحة = open
• مش مفتوحة = not open

This is the normal Egyptian Arabic way to negate an adjective sentence like this.

Almost, but not exactly.

In Modern Standard Arabic, you would more naturally say:

المحكمة مفتوحة اليوم

The main difference is:

• Egyptian: النهارده
• MSA: اليوم

The rest of the sentence works similarly:

• المحكمة = the court
• مفتوحة = open

So the Egyptian sentence is colloquial, while المحكمة مفتوحة اليوم is the more formal Standard Arabic version.

Yes. Just like English open, مفتوح / مفتوحة can mean different kinds of openness depending on context.

In this sentence, it most naturally means:

• the court is open
• the court is operating
• the court is not closed today

So it is not necessarily about a door being physically open. It refers to the institution being open for service.
