İtiraz gerekçesi kabul edilince iptal kararı gönderildi.

-ince / -ınca / -ünce / -unca is a verb suffix meaning when, once, or after something happens.

So:

• kabul edilince = when it was accepted / once it was accepted

In this sentence, it connects the first event to the second one:

• first: the objection ground was accepted
• then: the cancellation decision was sent

It often gives a natural sequence of events, similar to upon being accepted or after it was accepted.

Because kabul etmek is a common Turkish compound verb:

• kabul = acceptance
• etmek = to do / to make

Together, kabul etmek means to accept.

Its passive form is:

• kabul edilmek = to be accepted

So:

• kabul edilince comes from kabul edilmek
• it stays written as two words because the compound verb is still structurally there

This is very common in Turkish:

• yardım etmek = to help
• fark etmek = to notice
• iptal etmek = to cancel
• kabul etmek = to accept

Here -si is not a random ending. It is the 3rd person possessive suffix, and it appears in a very common Turkish noun construction.

• gerekçe = reason, justification, grounds
• gerekçesi = its reason / reason of X

In itiraz gerekçesi, the structure is a noun compound:

• itiraz = objection
• gerekçesi = its reason/grounds

So the whole phrase means something like the objection grounds or the reason for the objection.

This pattern is extremely common in Turkish:

• iptal kararı = cancellation decision
• öğrenci kimliği = student ID
• başvuru formu = application form

In these compounds, the second noun usually takes this possessive ending.

Both are possible, but they are not exactly the same in feel.

itiraz gerekçesi

This is an indefinite noun compound. It is the more standard, compact, institutional way to say:

• objection grounds
• reason for objection

itirazın gerekçesi

This is a genitive + possessed structure. It feels more like:

• the reason of the objection
• the objection’s reason

This version is often more specific or more explicitly possessive.

In formal or bureaucratic Turkish, the shorter compound form itiraz gerekçesi is very common.

In iptal kararı, the ending on kararı is mainly part of the same noun-compound pattern as above.

• iptal = cancellation
• karar = decision
• kararı = decision of cancellation / cancellation decision

So the -ı here is from the compound structure, not just because it is an object.

This is important because learners often confuse:

• possessive ending in compounds with
• accusative case

In this sentence, iptal kararı is actually the thing that was sent, so in the passive sentence it functions like the grammatical subject:

• İptal kararı gönderildi = The cancellation decision was sent

So the -ı in kararı is part of the noun phrase itself, not an extra accusative marker added afterward.

Because it contains the passive marker -il-.

Break it down like this:

• gönder- = send
• gönderil- = be sent
• gönderildi = was sent

More exactly:

• -di = past tense
• 3rd person singular has no separate ending here

Compare:

• gönderdi = he/she/it sent
• gönderildi = it was sent

So the extra -il- is what makes it passive.

Because Turkish often leaves the agent unstated, especially in:

• passive sentences
• formal writing
• bureaucratic or official language

Here the focus is on the action and result, not on who did it.

So instead of saying:

• Someone sent the cancellation decision

Turkish uses the passive:

• İptal kararı gönderildi = The cancellation decision was sent

This is very natural in administrative Turkish.

Sometimes -ince can create a context where English might translate it in a slightly causal way, but its core meaning is usually when / once / after.

So kabul edilince primarily means:

• when it was accepted
• once it was accepted

In real context, the sequence may imply a reason:

• it was accepted, so the next step happened

But grammatically, the suffix itself is mainly temporal, not a direct because marker.

If Turkish wanted to state cause more explicitly, it might use forms like:

• kabul edildiği için = because it was accepted

Yes, and the meaning would be very close.

kabul edilince

Often feels like:

• when / once / after
• slightly more event-to-event, sequential

kabul edildiğinde

Often feels like:

• when
• slightly more neutral or descriptive

In many contexts, both work. But -ince often sounds a bit more like:

• as soon as that happened, the next thing happened

So in this sentence, kabul edilince fits the idea of a procedural step leading to the next one.

Turkish very often puts the time or condition clause before the main clause.

So this order is very natural:

• İtiraz gerekçesi kabul edilince → first event/context
• iptal kararı gönderildi → main event

English can also do this:

• When X happened, Y happened

Turkish especially likes this kind of ordering because it sets up the context first and then gives the main action.

You could also rearrange it for emphasis, for example:

• İptal kararı, itiraz gerekçesi kabul edilince gönderildi.

But the original order is smoother and more standard.

Yes. It sounds very much like official, administrative, or legal/bureaucratic Turkish.

Clues include:

• noun compounds like itiraz gerekçesi and iptal kararı
• passive verbs like gönderildi
• no explicit human subject
• compact, procedural wording

In everyday speech, people might use a more explicit and less compressed sentence. But in documents, reports, or institutional messages, this style is very common.

A helpful way to see it is:

[subordinate time clause] + [main passive clause]

Subordinate clause

• İtiraz gerekçesi kabul edilince
• when the objection grounds were accepted

Main clause

• iptal kararı gönderildi
• the cancellation decision was sent

So the sentence is built as:

• When X happened, Y was done

That pattern is extremely common in Turkish.
