Bu veriler bilgisayarda depolanıyor.

In Turkish, bu can mean both this and these. It does not change for singular vs. plural.

So:

• bu veri = this piece of data / this data
• bu veriler = these data

The plurality is shown by veriler (veri + -ler), not by changing bu.

Veriler comes from:

• veri = data
• -ler = plural suffix

So:

• veri = data
• veriler = data / pieces of data / the data in a plural sense

A small note: in modern Turkish, veri is often treated a bit like an uncountable noun in some contexts, but veriler is also very common when talking about multiple data items or a set of data.

Turkish does not have a separate word like English the.

Whether something is understood as the, some, or just a general noun depends on context.

So bu veriler already means something like these data, which is definite because bu points to specific data.

Bilgisayarda means in the computer or on the computer, depending on the context in English.

It is formed like this:

• bilgisayar = computer
• -da = locative suffix, meaning in / on / at

So:

• bilgisayarda = in/on the computer

Turkish uses this locative ending instead of a separate preposition like English in or on.

The locative suffix has several forms:

• -da
• -de
• -ta
• -te

The form depends on vowel harmony and consonant voicing.

For bilgisayar:

• the last vowel is a, so we need the a-type form: -da or -ta
• the word ends in r, which is a voiced consonant, so we use d, not t

That gives:

• bilgisayar + da → bilgisayarda

The base verb is depolamak, which means to store.

From that verb, Turkish builds depolanıyor.

So the core meaning comes from:

• depolamak = to store

Because the sentence is using a conjugated verb, not the dictionary form.

Here is the breakdown:

• depolamak = to store (dictionary form)
• depolan- = to be stored (passive form)
• depolanıyor = is being stored / are being stored

So depolanıyor is not just the verb stem. It includes both:

1. a passive marker
2. a present continuous ending

The -n- here makes the verb passive.

Compare:

• depolamak = to store
• depolanmak = to be stored

So:

• Şirket verileri depoluyor. = The company is storing the data.
• Veriler depolanıyor. = The data are being stored.

In your sentence, the data are not doing the action themselves. They are receiving the action, so the passive is used.

This is the Turkish present continuous marker, often written as -yor with a harmony vowel before it.

In depolanıyor, it shows an ongoing action:

• depolanıyor = is being stored / are being stored

The exact form changes depending on the verb stem because of vowel harmony.

So -yor is the key part meaning something like is ...-ing / are ...-ing.

Turkish verbs in the 3rd person usually do not have to change for singular vs. plural the way English verbs do.

So:

• Veri depolanıyor. = The data/item is being stored.
• Veriler depolanıyor. = The data are being stored.

The plural meaning comes from veriler, not from a special plural verb form.

Turkish can sometimes use plural verb endings with plural subjects, but in ordinary sentences like this, the singular-looking 3rd person form is completely normal.

It is the subject.

That may feel strange to an English speaker at first because the meaning is passive.

Compare:

• Active: Birisi bu verileri bilgisayarda depoluyor.
  Someone is storing these data on the computer.
  Here verileri is the object.

• Passive: Bu veriler bilgisayarda depolanıyor.
  These data are being stored on the computer.
  Here veriler becomes the subject.

A helpful clue is that veriler has no accusative ending like -i. In the passive sentence, it is not the direct object.

Because veriler is the subject here, not the definite direct object.

• veriler = data / the data as subject
• verileri = the data as definite direct object

For example:

• Bu veriler depolanıyor. = These data are being stored.
• Sistem bu verileri depoluyor. = The system is storing these data.

In the second sentence, verileri is the object of depoluyor, so it takes the accusative ending.

The sentence follows a very common Turkish pattern:

Subject + place expression + verb

So:

• Bu veriler = subject
• bilgisayarda = location
• depolanıyor = verb

Turkish often puts the verb at the end, which is one of the biggest differences from English.

Yes. Turkish word order is flexible, although the verb usually stays at the end.

For example, these are possible:

• Bu veriler bilgisayarda depolanıyor.
• Bilgisayarda bu veriler depolanıyor.

Both are grammatical, but the emphasis changes slightly.

• Starting with Bu veriler focuses first on these data
• Starting with Bilgisayarda highlights the location: on the computer / in the computer

Most directly, depolanıyor means is being stored / are being stored, because -yor usually expresses an ongoing action.

However, in real translation, English may sometimes prefer is stored / are stored, depending on context, especially in technical writing.

So this sentence could be understood as:

• These data are being stored on the computer.
• or, in some contexts, These data are stored on the computer.

The more literal grammatical value is the ongoing one: are being stored.

In Turkish, a lot of meaning that English expresses with separate helper words is packed into one verb form.

English:

• are being stored

Turkish:

• depolanıyor

That one Turkish verb includes:

• the basic action: store
• passive meaning: be stored
• ongoing/present continuous meaning: are being

So Turkish often uses suffixes where English uses separate words.

Both can be possible depending on context.

Turkish -da/-de is broader than a single English preposition. It just marks location.

So bilgisayarda could mean:

• in the computer if you are thinking about data inside the system or memory
• on the computer if you are thinking in the more natural everyday English way

In many contexts, English speakers would say on the computer, but in technical contexts in the computer can also make sense.

Yes. An active version would mention who or what stores the data.

For example:

• Sistem bu verileri bilgisayarda depoluyor.
  The system is storing these data on the computer.

Your original sentence leaves out the doer and focuses on the data themselves, so the passive is more natural there:

• Bu veriler bilgisayarda depolanıyor.

The dictionary form is depolanmak.

Breakdown:

• depolamak = to store
• depolanmak = to be stored
• depolanıyor = is being stored / are being stored

When looking words up, you would usually look for either:

• depolamak
• or depolanmak

depending on whether you want the active or passive form.

Yes, it is natural and grammatical.

It sounds like the kind of sentence you might see in:

• technical documentation
• software or database discussions
• IT/security contexts
• formal explanations

If the context is data storage, Bu veriler bilgisayarda depolanıyor. is a very normal sentence.
