Teslim tutanağında denetim raporundan bahsediliyor.

The base form is teslim tutanağı.

This is a noun phrase meaning something like a delivery record/report. It is a type of noun compound in Turkish:

• teslim = delivery, handover
• tutanak = written record, report, minutes
• teslim tutanağı = delivery record

The final -ı in tutanağı is part of the compound structure, not just an ordinary case ending.

Also notice the sound change:

• tutanak → tutanağı

This happens because final k often becomes ğ when a vowel-initial ending is added.

-da / -de is the locative case, often meaning in, on, at.

So:

• teslim tutanağı = the delivery record
• teslim tutanağında = in/on the delivery record

Here it tells you where the mentioning happens: it is mentioned in the delivery record.

Because the verb bahsetmek / bahsedilmek normally takes the ablative case: -dan / -den.

So in Turkish, you do not simply say mention the inspection report with a direct object pattern like in English. Instead, Turkish uses a structure closer to:

• something is mentioned from / regarding X

That is why you get:

• denetim raporu = the inspection report
• denetim raporundan = about/from the inspection report

With bahsetmek, this ablative marking is standard:

• ondan bahsetmek = to mention him/her/it, to talk about that
• kitaptan bahsetmek = to mention the book, to talk about the book

That -n- is a buffer consonant.

The base form is:

• denetim raporu

When you add a case ending to a possessed noun like this, Turkish often inserts -n- before the case ending:

• raporu
  • -dan → raporundan

This is very common with 3rd-person possessed forms.

Compare:

• araba → arabadan
• arabası → arabasından

So raporundan is exactly what you expect from raporu + -ndan.

Yes, bahsediliyor is a passive form.

Breakdown:

• bahsetmek = to mention, to talk about
• bahsedilmek = to be mentioned
• bahsediliyor = is being mentioned / is mentioned

So the sentence is built like an impersonal passive:

• Teslim tutanağında denetim raporundan bahsediliyor.
• The inspection report is mentioned in the delivery record.
• more literally: In the delivery record, mention is being made of the inspection report.

Turkish often prefers this kind of passive wording where English might use an active subject like they mention... or a passive like ...is mentioned.

There is no explicit subject.

This is a very common Turkish pattern: an impersonal passive. The sentence does not say who is doing the mentioning. It simply states that the mentioning happens.

So instead of saying:

• Someone mentions the inspection report in the delivery record

Turkish naturally says:

• Teslim tutanağında denetim raporundan bahsediliyor
• literally: In the delivery record, it is being mentioned about the inspection report

In smoother English, we just say:

• The inspection report is mentioned in the delivery record.

It can do both, depending on context.

-iyor often corresponds to:

• is mentioning / is being mentioned
• but also sometimes mentions / is mentioned

In this sentence, English would often prefer a general present passive:

• The inspection report is mentioned in the delivery record.

But Turkish still uses bahsediliyor, which is completely normal.

So do not assume -iyor always means a temporary action happening right now. It can also describe what a text currently says or contains.

Because Turkish word order normally puts the verb at the end.

So the structure is:

• Teslim tutanağında = in the delivery record
• denetim raporundan = about the inspection report
• bahsediliyor = is mentioned

That final verb position is very typical in Turkish.

English and Turkish organize information differently, so even if the English translation starts with the inspection report, Turkish does not need to.

Yes.

Both are examples of very common Turkish noun compounds:

• teslim tutanağı
• denetim raporu

In these compounds, the second noun usually takes a compound ending, often seen as -ı / -i / -u / -ü.

So:

• tutanak → tutanağı
• rapor → raporu

This is why learners should memorize these as whole units, not just as two separate nouns placed side by side.

Yes. A very common alternative is söz etmek.

For example:

• Teslim tutanağında denetim raporundan söz ediliyor.

This means almost the same thing.

Both bahsetmek and söz etmek are common for mentioning or talking about something, and both usually take the ablative:

• rapordan bahsetmek
• rapordan söz etmek

So if you understand one pattern, the other will feel familiar too.
