ההונאה התחילה בחיוב לא מוכר.

A natural pronunciation is:

ha-hona'a hitkhila be-khiyuv lo mukar

Approximate stress:

• ha-ho-na-A
• hit-KHI-la
• be-khi-YUV
• lo mu-KAR

A few notes:

• ח in התחילה and חיוב is the throaty sound like the ch in Scottish loch or German Bach.
• מוכר here is pronounced mu-KAR, not mo-KHER.

Because the word itself is הונאה, and Hebrew adds the definite article ה־ directly to the front of a noun.

So:

• הונאה = fraud / scam
• ההונאה = the fraud / the scam

Since the noun already starts with ה, adding another ה gives ההונאה.

The ה־ makes the noun definite, like the in English.

So:

• הונאה = a fraud / fraud
• ההונאה = the fraud

Using ההונאה suggests we are talking about a specific fraud case, not fraud in general.

Because הונאה is a feminine singular noun, and in the past tense Hebrew verbs agree with the subject in gender and number.

So:

• ההונאה התחילה = the fraud began

If the subject were masculine singular, you would expect התחיל instead.

התחילה is the past-tense form of להתחיל, meaning to begin or to start.

Here it is:

• past tense
• third person
• feminine singular

So literally it means she began, but because Hebrew uses grammatical gender for nouns, it can also mean it began when the noun is feminine, as with הונאה.

In this sentence, חיוב means something like a charge, billing entry, or debit on an account or card statement.

This word can have other meanings in other contexts, but here it clearly refers to a financial charge.

Because Hebrew often uses להתחיל ב־ for to start with or to begin with something.

So:

• התחילה בחיוב = started with a charge

The ב־ usually means in, at, or with, depending on context. In this sentence, with is the most natural English equivalent.

Because in Hebrew, adjectives normally come after the noun they describe.

So:

• חיוב מוכר = a familiar/recognized charge
• חיוב לא מוכר = an unfamiliar/unrecognized charge

This is the opposite of normal English word order, where adjectives usually come before the noun.

Hebrew does not have an indefinite article.

So:

• חיוב can mean a charge
• בחיוב can mean with a charge

Hebrew marks definiteness with ה־ for the, but if there is no ה־, the noun is often understood as indefinite.

It is the same spelling, but not the same meaning here.

Without vowel marks, מוכר can represent different words:

• מוֹכֵר = seller / selling
• מֻכָּר = known / familiar / recognized

In this sentence, לא מוכר means unrecognized or unfamiliar, not anything related to selling.

Because לא simply negates the adjective phrase.

So:

• מוכר = recognized / familiar
• לא מוכר = not recognized / unfamiliar

The adjective itself still has to match the noun:

• חיוב is masculine singular
• so מוכר is also masculine singular

If the noun were feminine singular, you would expect מוכרת instead.

Yes, there are other possible phrasings, but this one is natural and clear.

For example, Hebrew might also use:

• ההונאה התחילה עם חיוב לא מוכר
• ההונאה החלה בחיוב לא מוכר

But התחילה בחיוב לא מוכר is very idiomatic. The pattern להתחיל ב־ is especially common for to begin with something.
