Dilekçenin üstüne resmî damga vurulmadan işlem başlamıyormuş.

Dilekçenin is the genitive form of dilekçe, meaning petition, application, or written request.

• dilekçe = petition / application
• dilekçenin = of the petition

In this sentence, it is connected to üstüne. Turkish often uses a structure like:

• X-in üstü / üstüne = the top of X / onto the top of X

So dilekçenin üstüne literally means onto the petition or onto the top of the petition.

Üstüne comes from:

• üst = top / upper side
• üstü = its top / the top of it
• üstüne = onto its top / onto it

Here, dilekçenin üstüne means onto the petition.

The ending -e / -a here is the dative, which often gives a sense of direction or target. That fits the idea of stamping something onto a document.

Compare:

• üstünde = on it, on top of it, located on it
• üstüne = onto it, onto the surface of it

With damga vurmak, Turkish usually prefers the target form, so üstüne sounds natural.

Resmî damga means official stamp or official seal.

• resmî = official, formal
• damga = stamp, seal, mark

In bureaucratic contexts, this refers to the stamp that makes a document formally valid or ready for processing.

Yes. Damga vurmak is a very common expression meaning to stamp or to affix a stamp/seal.

Literally, vurmak often means to hit or strike, but in this phrase it does not mean physical hitting in the ordinary sense. It is just the normal Turkish way to talk about putting a stamp on something.

You may also hear:

• damga basmak = to stamp
• mühür basmak = to seal / stamp with an official seal

So resmî damga vurmak means to put an official stamp on something.

Vurulmadan can be broken down like this:

• vur- = stem of vurmak
• -ul- = passive
• -ma- = negation
• -dan = a converb ending meaning without doing, before doing

So:

• vurulmadan = without being stamped / before it is stamped

In this sentence, it means that the process does not begin unless/until an official stamp has been put on the petition.

A natural English sense is:

• without an official stamp being applied
• before an official stamp is applied
• unless it gets an official stamp first

The passive is used because the person who does the stamping is not important.

The sentence focuses on the requirement, not on the official or clerk performing the action.

So instead of saying:

• someone stamps the petition

Turkish says:

• the petition is stamped

This is especially common in formal, bureaucratic, and rule-based language.

It can express both, depending on context.

In many cases, -madan literally means without doing:

• yemeden çıktı = he left without eating

But in procedural sentences like this one, it often has the sense of before X happens or until X happens first:

• vurulmadan işlem başlamıyor = the process does not start before it is stamped

So here the most natural interpretation is:

• The procedure will not begin until an official stamp is put on the petition.

İşlem is a very common bureaucratic word. Depending on context, it can mean:

• process
• procedure
• transaction
• administrative action
• processing

In this sentence, işlem başlamıyormuş means something like:

• the procedure doesn’t begin
• processing doesn’t start
• the administrative process won’t start

It is singular here, and that is why the verb is also singular.

Başlamıyormuş contains:

• başla- = start, begin
• -mıyor = is not starting / does not start
• -muş = reported information, inference, or new realization

So başlamıyormuş means something like:

• apparently it doesn’t start
• it turns out it doesn’t start
• they say it doesn’t start

The speaker is not presenting this as direct, firsthand information. They may have heard it from someone else, read it somewhere, or just discovered it.

Compare:

• İşlem başlamıyor. = The process doesn’t start.
• İşlem başlamıyormuş. = Apparently, the process doesn’t start. / I hear the process doesn’t start.

This is a very common question. In Turkish, the present continuous form often expresses general rules or regular situations, especially in everyday speech.

So:

• başlamıyor can mean is not starting or does not start
• not only a right-now action, but also a general rule

That is why işlem başlamıyormuş can mean:

• the process apparently doesn’t start
• not necessarily right this second, but as a rule

A form like başlamazmış is also possible, but it sounds a bit different:

• başlamazmış = apparently it does not begin / apparently it never begins in such cases

That version can sound more general or proverbial. Başlamıyormuş is very natural in spoken Turkish for a practical rule.

The sentence is:

Dilekçenin üstüne resmî damga vurulmadan işlem başlamıyormuş.

A useful way to read it is:

• Dilekçenin üstüne = onto the petition
• resmî damga vurulmadan = without an official stamp being put on it
• işlem başlamıyormuş = apparently the procedure does not begin

So the whole structure is:

[Condition / prerequisite] + [main result]

Very literally:

Without an official stamp being put onto the petition, the procedure apparently does not begin.

More natural English:

Apparently, the procedure doesn’t start until an official stamp is put on the petition.

Yes, Turkish word order is flexible, but the original order is natural and clear.

The sentence puts the prerequisite first and the result last:

• Dilekçenin üstüne resmî damga vurulmadan = until the official stamp is applied to the petition
• işlem başlamıyormuş = the process apparently doesn’t begin

That ordering helps build toward the main point.

You could rearrange parts for emphasis, but the original sounds like normal administrative Turkish.
