Teknik resim patent başvurusuna eklendi.

• teknik = technical
• resim = picture, drawing, image
• patent başvurusu = patent application
• patent başvurusuna = to the patent application
• eklendi = was added

So the whole sentence means something like:

• The technical drawing was added to the patent application.

In context, teknik resim is best understood as technical drawing rather than just technical picture.

Because patent başvurusu is a noun phrase meaning patent application, and then Turkish adds the dative ending -na / -ne / -a / -e to show to.

Breakdown:

• başvuru = application
• patent başvurusu = patent application
• patent başvurusuna = to the patent application

More literally:

• başvuru = application
• başvuru-su = its application / application of patent
  This is the normal Turkish way of forming many noun compounds.
• başvurusu-na = to its application

So -na here is the dative ending attached after the compound form başvurusu.

This is a very common Turkish noun compound pattern.

When one noun modifies another noun, Turkish often uses this structure:

• first noun: bare form
• second noun: gets a 3rd person possessive ending

So:

• patent başvurusu = patent application
• literally something like the application of patent

Other similar examples:

• öğrenci kimliği = student ID
• araba kapısı = car door
• şehir merkezi = city center

This does not always sound possessive in English. It is just the normal Turkish way to build many noun-noun combinations.

Because eklendi is passive, while ekledi is active.

• ekledi = he/she/it added
• eklendi = was added

So:

• Teknik resim patent başvurusuna eklendi.
  = The technical drawing was added to the patent application.

If you said:

• Birisi teknik resmi patent başvurusuna ekledi.
  = Someone added the technical drawing to the patent application.

then ekledi would be appropriate, because the sentence has an active doer.

It comes from the verb eklemek = to add.

A useful breakdown is:

• ekle- = add
• -n- = passive marker
• -di = past tense

So:

• ekle-n-di = was added

This is a very common pattern in Turkish:

• yazıldı = was written
• açıldı = was opened
• gönderildi = was sent

Turkish does not have articles like the or a/an in the same way English does.

So teknik resim can mean:

• the technical drawing
• a technical drawing

and the exact meaning depends on context.

In this sentence, English usually prefers the technical drawing or a technical drawing was added, depending on the situation. Turkish leaves that unstated unless something else in the context makes it specific.

Because it is the subject of a passive sentence, not the direct object of an active one.

Compare these:

• Teknik resim patent başvurusuna eklendi.
  = The technical drawing was added to the patent application.
  Here teknik resim is the thing that underwent the action, so in Turkish passive structure it appears without the accusative ending.

• Mühendis teknik resmi patent başvurusuna ekledi.
  = The engineer added the technical drawing to the patent application.
  Here teknik resmi is the direct object, so it takes the accusative -i.

So the lack of -i is connected to the sentence being passive.

Here -na is the dative case, which often means:

• to
• toward
• into in some contexts

So:

• patent başvurusuna = to the patent application

With eklemek, the thing receiving the addition commonly takes the dative:

• dosyaya eklemek = to add to the file
• listeye eklemek = to add to the list
• başvuruya eklemek = to add to the application

So patent başvurusuna eklendi is exactly the expected pattern.

The sentence uses a very normal Turkish word order:

• Teknik resim — topic/subject
• patent başvurusuna — destination/target
• eklendi — verb at the end

Turkish usually puts the verb last, so this sounds natural and neutral.

You can change the order for emphasis, for example:

• Patent başvurusuna teknik resim eklendi.

This still means essentially the same thing, but it may emphasize where it was added.

So yes, the order can change, but the original is a standard, natural sentence.

Yes, resim often means picture or image, but in some contexts it can also mean drawing.

In the phrase teknik resim, it usually means:

• technical drawing
• engineering drawing

This is a set phrase in Turkish. So even though resim by itself can be broad, teknik resim has a more specific technical meaning.

Yes, that is very possible depending on context.

The verb eklemek can mean:

• to add
• to append
• to attach
  depending on what is being added and in what context

So these can all work:

• The technical drawing was added to the patent application.
• The technical drawing was attached to the patent application.
• The technical drawing was appended to the patent application.

In formal or administrative contexts, attached or appended may sound especially natural in English.

Not necessarily. Turkish often leaves the agent unstated, especially with the passive.

So:

• Teknik resim patent başvurusuna eklendi.

focuses on the result: the drawing is now part of the application.

If you want to say who did it, Turkish would usually switch to an active sentence, for example:

• Mühendis teknik resmi patent başvurusuna ekledi.
  = The engineer added the technical drawing to the patent application.

You can sometimes mention the agent in a passive-style expression too, but the active version is usually simpler and more natural for learners.

A rough pronunciation guide is:

• Teknik ≈ tek-neek
• resim ≈ reh-seem
• patent ≈ pah-tent
• başvurusuna ≈ bash-voo-roo-soo-nah
• eklendi ≈ ek-len-dee

A fuller rough version:

• tek-neek reh-seem pah-tent bash-voo-roo-soo-nah ek-len-dee

A few notes:

• ş sounds like sh
• ı is a vowel that does not exist in English; it is a relaxed sound somewhat like the vowel in sofa, but without fully sounding like uh
• stress in Turkish is often fairly even, though compounds and suffixes can affect it

If you want to sound natural, keep the vowels clear and avoid reducing them too much, unlike in English.
