Dilekçe ekinde itiraz gerekçesi açıklanıyor.

Literally, it is:

• dilekçe = petition, written application
• ek = attachment, appendix, annex
• ekinde = in its attachment / in the attachment

So dilekçe ekinde means in the attachment to the petition or in the petition’s attachment/appendix.

The form ekinde is built like this:

• ek
• eki = its attachment
• ekinde = in its attachment

That final -de is the locative ending, meaning in/on/at, and the n appears as a linking consonant before it.

This is a very common learner question because both patterns exist in Turkish.

Here, dilekçe ekinde uses an indefinite noun compound:

• dilekçe eki = petition attachment / attachment to a petition

This is a compact, very common Turkish way to combine nouns.

By contrast, dilekçenin ekinde is a genitive-possessive structure:

• dilekçenin eki = the attachment of the petition

In practice:

• dilekçe ekinde sounds more formulaic and bureaucratic
• dilekçenin ekinde sounds more explicitly possessive and definite

Both can make sense, but the version in your sentence is a very natural formal written style.

itiraz gerekçesi means the reason/grounds for the objection.

It is another noun compound:

• itiraz = objection
• gerekçe = reason, justification, grounds
• itiraz gerekçesi = objection reason / the grounds for objection

In Turkish noun compounds, the second noun usually gets a possessive-type ending. That is why it becomes gerekçesi, not just gerekçe.

So this is the same pattern as:

• okul kapısı = school gate
• ev kapısı = house door
• itiraz gerekçesi = objection reason

açıklanıyor comes from the verb açıklamak, meaning to explain.

Step by step:

• açıklamak = to explain
• açıklanmak = to be explained
• açıklanıyor = is being explained / is explained

So this is a passive form.

The passive is useful here because the sentence does not say who is explaining it. That is very common in formal and legal Turkish, where the style is often impersonal.

It can mean either, depending on context.

Although -iyor is often taught first as the present continuous, in real Turkish it can also be used more broadly. In formal writing like this, açıklanıyor often means something like:

• is explained
• is set out
• is stated

So in this sentence, it does not necessarily mean that someone is explaining it at this exact moment. It may simply mean that the grounds are presented in that attachment.

Because Turkish normally puts the finite verb at the end of the sentence.

Here the order is:

• Dilekçe ekinde = location/context
• itiraz gerekçesi = subject
• açıklanıyor = verb

This is a very normal Turkish sentence pattern.

You could also say:

• İtiraz gerekçesi dilekçe ekinde açıklanıyor.

That version gives a little more emphasis to itiraz gerekçesi, but the original order is perfectly natural.

Turkish has no articles exactly like English a/an and the.

So Turkish often leaves that information to context.

For example:

• dilekçe can mean a petition or the petition
• itiraz gerekçesi can mean the reason for the objection, a reason for objection, or the grounds for objection

In a formal sentence like this, English usually uses the, because the referents are understood from context.

Because Turkish and English do not always package ideas the same way.

Turkish often uses singular gerekçe for something that English may naturally express as:

• grounds
• reasons
• justification
• basis

So itiraz gerekçesi may be translated idiomatically as the grounds for the objection, even though the Turkish noun is singular.

If the writer wanted to highlight several separate reasons more explicitly, they could use itiraz gerekçeleri.

Yes, very formal.

Words like these are common in administrative, legal, and bureaucratic Turkish:

• dilekçe = petition / formal application
• itiraz = objection
• gerekçe = justification / grounds
• ek = attachment / annex

Also, the passive açıklanıyor adds to the formal tone. In everyday conversation, people might choose a more direct or less bureaucratic wording.
