بلغ الزبون عن احتيال وعملية مصرفية مشبوهة.

Here it is understood as بلّغ = ballagh, not balagh.

Why this matters:

• بلغ without a shadda can be ambiguous in normal Arabic writing.
• balagh usually means he reached / it reached.
• ballagh means he informed / reported / notified.

In this sentence, the presence of عن strongly tells you the intended verb is بلّغ عن = to report.

So a more fully spelled version would be:

بلّغ الزبون عن احتيال وعملية مصرفية مشبوهة.

Because بلّغ عن is the pattern used for reporting something.

So:

• بلّغ عن احتيال = reported fraud
• بلّغ عن مشكلة = reported a problem

You can think of عن here as part of the verb pattern, not as a word you translate too literally every time.

A useful contrast:

• بلّغ البنكَ عن المشكلة = he notified the bank about the problem
  
  • البنك is the party being notified
  • عن المشكلة is the thing being reported

Yes, الزبون بلّغ... is also correct.

Arabic often allows both:

• بلّغ الزبون... = verb first
• الزبون بلّغ... = subject first

The difference is mostly about style and emphasis:

• Verb-first often sounds more formal, written, or report-like
• Subject-first is very common in spoken Levantine

So in everyday Levantine, many speakers would naturally say:

الزبون بلّغ عن احتيال وعن عملية بنكية مشبوهة.

It is mostly formal / MSA-style, even though a Levantine speaker would understand it perfectly.

What makes it sound formal:

• بلّغ عن is common in formal reports
• احتيال is a formal word for fraud
• عملية مصرفية sounds official, administrative, or banking-related

A more everyday Levantine version might be:

• الزبون بلّغ عن احتيال وعن عملية بنكية مشبوهة
• or even more colloquially, depending on region/context:
  الزبون بلّغ عن نصب وعن عملية بنكية مشبوهة

Notes:

• احتيال is more formal than نصب
• مصرفية is more formal than بنكية in many contexts

Because Arabic is marking different kinds of reference.

• الزبون = the customer
  This refers to a specific customer, so it takes الـ.

• احتيال = fraud
  This is an abstract noun here, so it is naturally indefinite.

• عملية مصرفية مشبوهة = a suspicious banking transaction
  This is one unspecified transaction, so it is also indefinite.

If you meant a specific known suspicious transaction, you could say:

العملية المصرفية المشبوهة

The head noun is عملية = transaction / operation, and the words after it describe it.

Structure:

• عملية = transaction/operation
• مصرفية = banking / bank-related
• مشبوهة = suspicious

So literally it is:

transaction banking suspicious

This is normal Arabic word order:

• noun first
• then adjectives after it

Also, all three are feminine singular:

• عملية is feminine
• so the adjectives must match it:
  • مصرفية
  • مشبوهة

That agreement is very important in Arabic.

Yes. One عن can govern both items.

So:

• عن احتيال وعملية مصرفية مشبوهة
  means
• about fraud and a suspicious banking transaction

Arabic often does this, just like English can say:

• about fraud and a suspicious transaction

If you want extra clarity or a slightly more natural spoken rhythm, you can repeat it:

بلّغ الزبون عن احتيال وعن عملية مصرفية مشبوهة.

That repeated عن is especially common in speech.

Because عملية is a broad word. Its exact meaning depends on context.

It can mean:

• operation
• process
• procedure
• transaction

In banking or finance, عملية مصرفية usually means:

• banking transaction
• financial operation

So this is a good example of why Arabic learners should not attach only one English meaning to a word.

A Levantine-style pronunciation would be something like:

ballaġ iz-zabūn ʿan iḥtiyāl w-ʿamaliyye maṣrafiyye mashbūhe

A few helpful notes:

• بلّغ → ballaġ
• الزبون → the l of الـ assimilates because ز is a sun letter, so you hear iz-zabūn rather than al-zabūn
• و is often just a quick w-
• final ة in Levantine is often pronounced -e, so:
  • عملية → ʿamaliyye
  • مصرفية → maṣrafiyye
  • مشبوهة → mashbūhe

If you read it in a more formal MSA style, the pronunciation would be closer to: ballagha az-zabūnu ʿan iḥtiyālin wa-ʿamaliyyatin maṣrifiyyatin mashbūhatin
with case endings, though those are usually not pronounced in everyday speech.

Both can work, but they differ in tone.

• مصرفية = more formal, official, institutional
• بنكية = more everyday, common in speech

So:

• عملية مصرفية sounds like report language, banking policy language, or official Arabic
• عملية بنكية sounds a bit more conversational

In a sentence like this, مصرفية fits the formal tone very well.

In normal Arabic writing, short vowels and case endings are usually omitted.

So you see: بلغ الزبون عن احتيال وعملية مصرفية مشبوهة

But in a fully vocalized formal version, it would be:

بلّغَ الزبونُ عن احتيالٍ وعمليةٍ مصرفيةٍ مشبوهةٍ

Breakdown:

• بلّغَ = past tense verb
• الزبونُ = subject, nominative
• عن احتيالٍ = after a preposition, genitive
• وعمليةٍ مصرفيةٍ مشبوهةٍ = also genitive after عن

In Levantine speech, learners normally do not pronounce these case endings. They are mostly relevant for formal grammar and careful MSA.
