البنك مفتوح من بدري النهارده.

A natural Egyptian pronunciation is:

el-bank maftūḥ men badri en-naharda

A few quick notes:

• البنك → el-bank
  The ال is pronounced el- here.
• مفتوح → maftūḥ
  The ح is a deep h sound from the throat.
• من بدري → men badri
  In fast speech, this often sounds very smooth and connected.
• النهارده → en-naharda
  This is the common Egyptian word for today.

If you say it naturally, the stress usually falls roughly like this:

el-BANK maf-TŪḤ men BAD-ri en-na-HAR-da

In Egyptian Arabic, as in Arabic generally, the verb to be in the present tense is usually omitted.

So instead of saying:

• The bank is open

Arabic simply says:

• البنك مفتوح

Literally, that is more like:

• the bank open

But it means The bank is open.

This is completely normal in present-tense sentences with adjectives, nouns, and locations.

البنك means the bank.

Yes, بنك is a borrowed word, ultimately from European languages. In Egyptian Arabic, it is fully normal and common.

Breakdown:

• بنك = bank
• الـ = the

So:

• البنك = the bank

مفتوح means open.

In this sentence, it works like an adjective describing the bank:

• البنك مفتوح = The bank is open

Grammatically, مفتوح comes from the root related to opening, and historically it is a passive participle, but for a learner, the most useful thing is simply:

• مفتوح = open
• مقفول = closed

Very common pair:

• المحل مفتوح = The shop is open
• المحل مقفول = The shop is closed

Yes. مفتوح is masculine singular here because البنك is masculine singular.

In Arabic, adjectives usually agree with the noun they describe.

So:

• masculine singular: مفتوح
• feminine singular: مفتوحة

For example:

• البنك مفتوح = The bank is open
• المدرسة مفتوحة = The school is open

So the form مفتوح matches البنك.

من بدري is a very common Egyptian expression meaning:

• early
• since early
• from early on

Literally:

• من = from
• بدري = early / early on

But together, من بدري often works like an idiomatic time expression. In this sentence, it suggests that the bank has been open since earlier than expected or since early in the day.

So:

• البنك مفتوح من بدري النهارده

can feel like:

• The bank has been open since early today
• The bank is open early today

The exact English translation depends on context.

بدري means early.

It is extremely common in Egyptian Arabic.

Examples:

• صحيت بدري = I woke up early
• جيت بدري = I came early
• بدري قوي = very early

In the sentence من بدري, it becomes part of a fixed expression meaning something like since early or from early on.

النهارده means today, and yes, it is the normal Egyptian Arabic word.

You may also see it spelled:

• النهاردة

Both represent the same Egyptian word.

This is different from Modern Standard Arabic, which usually uses:

• اليوم = today

So in Egyptian conversation, النهارده is much more natural.

In Egyptian Arabic, time expressions are often placed at the end very naturally.

So:

• البنك مفتوح من بدري النهارده

is a normal word order.

It is basically:

• The bank
  • open
    • since early
      • today

Arabic is flexible, so النهارده can sometimes appear earlier for emphasis, but the version here sounds very natural and conversational.

It can suggest either, depending on context, but the stronger feeling with من بدري is often:

• The bank has been open since early today
• The bank has been open from early on today

If someone just wants to say The bank opens early today, they might choose a slightly different wording depending on the exact meaning.

So the sentence here is more about the bank already being in the state of being open from early in the day, not just a general schedule.

You might hear بدري in other contexts, but مفتوح من بدري is the more natural expression for this meaning.

Compare:

• مفتوح من بدري = open since early / has been open from early on
• بدري by itself = early

Without من, the sentence may sound less idiomatic for this exact idea. So for a learner, من بدري is the safer, more natural choice here.

Yes, many speakers do say فاتح in everyday Egyptian Arabic.

Both can be used for places like shops, banks, restaurants, and so on:

• البنك مفتوح = The bank is open
• البنك فاتح = The bank is open

A rough difference:

• مفتوح focuses on the state of being open
• فاتح is also very common colloquially for businesses being open

In everyday speech, both are natural. مفتوح is very clear and widely understood.

Yes. In Arabic, this is a complete nominal sentence.

The structure is:

• البنك = the subject
• مفتوح = the predicate
• من بدري النهارده = time-related information

So even without a separate word for is, the sentence is fully complete and normal.

A possible Modern Standard Arabic version would be:

المصرف مفتوح منذ الصباح اليوم
or
البنك مفتوح منذ وقت مبكر اليوم

Notes:

• المصرف is a more formal MSA word for bank
• منذ is a more formal equivalent of since
• اليوم = today

But in Egyptian everyday speech, البنك مفتوح من بدري النهارده sounds much more natural.

A natural negative would be:

البنك مش مفتوح من بدري النهارده

This means something like:

• The bank isn’t open early today
• The bank hasn’t been open since early today

In Egyptian Arabic, مش is the common way to negate adjective sentences like this.

Examples:

• البنك مفتوح = The bank is open
• البنك مش مفتوح = The bank is not open

A very natural yes/no question would be:

البنك مفتوح من بدري النهارده؟

Often, Egyptian Arabic can make a question just by using rising intonation.

You could also say:

هو البنك مفتوح من بدري النهارده؟

Here, هو helps introduce the question, somewhat like So, is the bank open early today?

Both are natural, but the first one is very common in speech.
