İtiraz dilekçesi itiraz süresi bitmeden gönderildi.

Because it belongs to two different noun phrases:

• itiraz dilekçesi = objection petition / petition of objection
• itiraz süresi = objection period / period for objection

Turkish often repeats the noun instead of replacing it with something like the or that. So this repetition is normal and natural.

Dilekçe means petition or formal written request/application.

The -si here is part of a very common Turkish structure called an indefinite noun compound:

• itiraz dilekçesi = literally objection petition-its
• natural English: objection petition / petition of objection

In Turkish, when one noun modifies another noun this way, the second noun usually takes -(s)I:

• okul kapısı = school door
• otobüs durağı = bus stop
• itiraz dilekçesi = objection petition

Since dilekçe ends in a vowel, the linking s appears: dilekçe + si.

For the same reason as dilekçesi above: itiraz süresi is also an indefinite noun compound.

• süre = period, duration
• itiraz süresi = objection period

In this pattern, the second noun takes the compound ending -(s)I. So süre becomes süresi.

Bitmeden comes from bitmek = to end, to finish.

The ending -meden / -madan means without doing or, in many time expressions, before doing.

So:

• bitmeden = before it ended / without it ending

In this sentence, the natural meaning is before the objection period expired/ended.

Literally, -meden / -madan is closer to without doing.

Examples:

• yemeden çıktı = he left without eating
• konuşmadan gitti = she left without speaking

But with time-related verbs, it often has the practical meaning before:

• ders başlamadan geldim = I came before the class started
• süre bitmeden başvurun = apply before the time runs out

So in your sentence, bitmeden is understood temporally as before it ended.

Yes. Bitmeden önce is also possible and means the same thing: before it ended.

• itiraz süresi bitmeden gönderildi
• itiraz süresi bitmeden önce gönderildi

The version without önce is already complete and natural. Adding önce can make the before relationship a little more explicit, but it is not necessary.

Gönderildi is the passive past form of göndermek = to send.

• gönderdi = sent
• gönderildi = was sent

Turkish uses the passive very often when the doer is unknown, unimportant, or simply not mentioned. In this sentence, the focus is on the fact that the petition was sent, not on who sent it.

This is especially common in formal, legal, and administrative Turkish.

Because in this sentence itiraz dilekçesi is not the direct object of an active verb. It is the subject-like element of a passive sentence.

Compare:

• Active: Birisi itiraz dilekçesini gönderdi.
  = Someone sent the objection petition.
  Here dilekçesini is the direct object, so it takes the accusative.

• Passive: İtiraz dilekçesi gönderildi.
  = The objection petition was sent.
  Here it is no longer the object of the sentence, so there is no accusative.

That is why you see dilekçesi, not dilekçesini.

It is the simple past with -di.

• gönderil- = passive stem, be sent
• -di = past tense

So gönderildi means was sent.

This tense is used for a definite, factual past event. In a formal sentence like this, it sounds like a straightforward record of what happened.

Because the normal Turkish sentence pattern places the main verb at the end.

So the sentence is structured like this:

• İtiraz dilekçesi = the objection petition
• itiraz süresi bitmeden = before the objection period ended
• gönderildi = was sent

Turkish is more flexible than English, but verb-final order is the most neutral and standard pattern, especially in formal writing.

It has two main parts:

1. Main clause
   İtiraz dilekçesi gönderildi.
   = The objection petition was sent.

2. Subordinate time clause
   itiraz süresi bitmeden
   = before the objection period ended

So the full structure is:

[The objection petition] [before the objection period ended] [was sent].

A very literal breakdown would be:

• İtiraz dilekçesi = objection petition
• itiraz süresi = objection period
• bitmeden = before ending / without ending
• gönderildi = was sent

Yes, very much so.

Words like itiraz, dilekçe, süre, and the passive gönderildi are all common in administrative and legal Turkish. A native speaker would immediately recognize this as official-style language rather than everyday casual conversation.

In casual speech, someone might say something less formal depending on context, but this sentence sounds perfectly natural in a legal or bureaucratic setting.
