Tahsilat görevlisi müşteriyi iki kez borçlandırdı.

Tahsilat görevlisi means something like collections officer, collection clerk, or staff member responsible for collections/payments.

The -si on görevlisi is part of a very common Turkish noun compound pattern:

• tahsilat = collection, receipt of payment
• görevli = officer, staff member, attendant
• tahsilat görevlisi = collections officer

That -si does not mean literal possession here. It is the normal marker used in many compound nouns, similar to:

• satış görevlisi = sales assistant
• banka kartı = bank card
• otobüs durağı = bus stop

So you should learn tahsilat görevlisi as a set expression.

Because müşteriyi is the direct object of the verb, and it is definite/specific.

• müşteri = customer
• müşteriyi = the customer

In Turkish, a definite direct object usually takes the accusative ending. Here, the person being charged is a specific customer, so Turkish marks that with -yi.

Compare:

• müşteri borçlandırdı would be ungrammatical here
• müşteriyi borçlandırdı = charged the customer

The accusative ending here is basically -(y)I, where the vowel changes by vowel harmony.

For müşteri:

• the last vowel is i
• so the accusative vowel is also i
• because the noun already ends in a vowel, Turkish inserts a buffer y

So:

• müşteri
  • -(y)i → müşteriyi

This is the same pattern as:

• arabayı = the car
• masayı = the table
• kediyi = the cat

Yes. İki kez means twice or two times.

All of these are possible:

• iki kez
• iki kere
• iki defa

They are very close in meaning. İki kez can sound a little more neutral or slightly formal/written, while iki kere is very common in everyday speech.

So these are all natural:

• Müşteriyi iki kez borçlandırdı.
• Müşteriyi iki kere borçlandırdı.
• Müşteriyi iki defa borçlandırdı.

Borçlandırdı is the past-tense form of borçlandırmak.

You can understand it like this:

• borç = debt
• borçlandırmak = to put into debt, to charge, to debit
• borçlandırdı = charged / debited / put into debt

The ending -dı is the simple past ending here.

So:

• borçlandır- = verb stem
• -dı = past tense
• the subject is third-person singular, so there is no extra ending needed here

In this sentence, it means the collections officer charged/debited the customer.

It is a more formal/commercial verb than a very basic English verb like charge.

Depending on context, borçlandırmak can mean:

• to charge
• to bill
• to debit
• to place under a debt/owed amount

In a business, accounting, or payment context, it often suggests that an amount was entered against the customer, so the customer became liable for that amount.

So in this sentence, the idea is not just general money movement, but specifically that the customer was charged twice.

Because Turkish normally prefers Subject–Object–Verb order.

This sentence is:

• Tahsilat görevlisi = subject
• müşteriyi = object
• iki kez = adverbial expression
• borçlandırdı = verb

So the verb naturally comes at the end.

This is one of the biggest differences from English, which usually puts the verb earlier:

• English: The collections officer charged the customer twice.
• Turkish: Collections officer the customer twice charged.

That last-at-the-end verb position is very normal in Turkish.

Yes, Turkish word order is flexible, but the default version here is very natural.

For example, these are also possible:

• Tahsilat görevlisi iki kez müşteriyi borçlandırdı.
• Müşteriyi tahsilat görevlisi iki kez borçlandırdı.

They all mean basically the same thing, but the emphasis changes.

The original sentence:

• Tahsilat görevlisi müşteriyi iki kez borçlandırdı.

is a neutral, straightforward way to say it.

A moved version may highlight:

• iki kez = the fact that it happened twice
• müşteriyi = the customer
• tahsilat görevlisi = the person responsible

So yes, Turkish allows movement, but it is often about focus/emphasis, not a totally different meaning.

Turkish does not use articles the way English does.

There is no separate word exactly like the here. Instead, definiteness is often shown by context and grammar.

In this sentence:

• müşteriyi is clearly definite because it has the accusative ending, so the customer is the most natural interpretation.
• tahsilat görevlisi can be understood from context as the collections officer or sometimes a collections officer, depending on the situation.

So Turkish often leaves article-like meaning to:

• case marking
• word order
• context

Yes. Borçlandırdı is in the simple past (-dı), and it presents the action as a completed event in the past.

So the sentence means that the charging happened and is finished.

It does not mean:

• was charging
• used to charge
• has apparently charged

It means a completed past action: the officer charged the customer twice.

A rough pronunciation guide:

• Tahsilat → tah-see-LAHT
• görevlisi → guh-REV-li-si with ö pronounced like German ö or French eu
• müşteriyi → müsh-te-ri-yi with:
  • ü like German ü or French u
  • ş = sh
• iki → ee-kee
• kez → kez
• borçlandırdı → borch-lan-duhr-DUH

A few key letters:

• ç = ch
• ş = sh
• ı = a sound with no exact English equivalent; a short, neutral back vowel
• ö and ü are rounded front vowels, like in German or French

The stress is often heard roughly like this:

tahsilat görevlisi müşteriyi iki kez borçlandırdı

with noticeable stress near -lat in tahsilat and on the final verb area in normal speech.

Grammatically, iki kez simply says the action happened two times.

So the sentence means the officer charged the customer twice. That could mean:

• the same charge was entered twice by mistake
• the customer was billed on two separate occasions

The exact real-world interpretation depends on context. The grammar itself only tells you the action happened twice.
