Yapı ruhsatı denetim raporuna eklendi.

Not here. In yapı ruhsatı, the -ı is the standard ending used on the second noun in a common Turkish noun compound.

So:

• yapı = building / construction
• ruhsat = permit / license
• yapı ruhsatı = building permit / construction permit

This is a very common pattern in Turkish. The ending can look like the accusative, but in this sentence it is part of the noun phrase itself, not an object marker.

It is an indefinite noun compound. Turkish often expresses ideas like building permit, inspection report, car door, or school bag with this pattern:

• first noun: bare form
• second noun: takes a possessive-looking ending

Examples:

• okul çantası = school bag
• araba kapısı = car door
• yapı ruhsatı = building permit

So yapı ruhsatı functions as one unit.

Because denetim raporu is also a noun compound:

• denetim = inspection / audit
• raporu = report

When you add the dative ending -a / -e to this compound, it attaches to the already-marked second noun:

• denetim raporu = inspection report
• denetim raporuna = to the inspection report

So the full buildup is:

• rapor
• raporu
• raporuna

That -n- is a buffer consonant. In Turkish, when a noun already has a 3rd-person possessive ending and then takes another suffix, -n- often appears between them.

So:

• rapor-u = its report / the report in the compound form
• rapor-u-na = to the report

This is why you get raporuna, not raporu-a.

Eklendi is the past tense form of eklenmek, and here it is best understood as was added or got added.

Breakdown:

• ekle- = add
• eklen- = be added
• eklendi = was added

Turkish does not need a separate word for was here; the verb form already contains that meaning.

Yes. In this sentence, it is passive in meaning.

Compare:

• Memur yapı ruhsatını ekledi. = The officer added the building permit.
• Yapı ruhsatı eklendi. = The building permit was added.

So the thing receiving the action, yapı ruhsatı, is what the sentence focuses on.

Because Turkish normally puts the verb at the end of the sentence. That is one of the most basic word-order patterns in Turkish.

This sentence follows a very normal order:

• Yapı ruhsatı = subject / topic
• denetim raporuna = destination / target
• eklendi = verb

Other word orders are possible for emphasis, but this one is very natural.

Turkish usually does not use articles the way English does. There is no direct equivalent of the in ordinary sentences, and a/an is often omitted unless it needs emphasis.

So depending on context, this sentence could correspond to English versions like:

• The building permit was added to the inspection report.
• A building permit was added to the inspection report.

English must choose an article, but Turkish often leaves that to context.

No. They are related, but not the same.

• denetim raporu = inspection report
• denetimin raporu = the report of the inspection

The first one is a standard noun compound, very common in Turkish. The second one is a more explicit genitive-possessive structure. In your sentence, denetim raporuna comes from the first type.

Yes. In administrative or formal contexts, eklemek / eklenmek can mean:

• added
• attached
• appended
• included

So depending on the wider context, Yapı ruhsatı denetim raporuna eklendi could sound like:

• the building permit was added to the inspection report
• the building permit was attached to the inspection report
• the building permit was included in the inspection report

Because of the case marking and the verb.

• denetim raporuna has the dative ending, so it means to the inspection report
• yapı ruhsatı has no case ending here that would make it the destination

That leaves yapı ruhsatı as the item that underwent the action of eklendi.

Because of vowel harmony. The dative suffix is:

• -a after back vowels
• -e after front vowels

In raporu, the last vowel is a back vowel, so the form becomes raporuna. This is a regular Turkish sound pattern.
