Kod telsizle bildirildi.

Telsizle is telsiz + -le.

The suffix -le / -la means with / by means of / using. In this sentence, it shows the instrument or means used to do the action.

So:

• telsiz = radio / walkie-talkie
• telsizle = by radio, via radio, with a radio

This suffix follows vowel harmony, so it can appear as -le or -la.

Examples:

• telefonla aradı = he/she called by phone
• otobüsle geldi = he/she came by bus

The verb is bildirildi.

It comes from the verb bildirmek, which means to report, to notify, or to communicate.

It can be broken down like this:

• bildir- = report / notify
• -il- = passive marker
• -di = past tense

So bildirildi means was reported / was communicated / was notified.

The passive is used because the sentence focuses on the code, not on who reported it.

So instead of saying:

• Birisi kodu telsizle bildirdi. = Someone reported the code by radio.

Turkish uses:

• Kod telsizle bildirildi. = The code was reported by radio.

This is very natural in Turkish when the person doing the action is unknown, unimportant, or simply not mentioned.

Because kod is the subject of the passive sentence.

In an active sentence, you would say:

• Birisi kodu bildirdi.
• kodu is the direct object, so it takes the accusative ending -u.

But in the passive version:

• Kod bildirildi.
• kod becomes the grammatical subject, so it appears without the accusative ending.

That is a very common change when turning active sentences into passive ones.

No, they are related in form but not the same in meaning.

• bilmek = to know
• bildirmek = to report, to notify, to inform, to communicate

Even though they look similar, bildirmek is its own verb and is often used in official, formal, or procedural contexts.

In this sentence, bildirildi sounds more like was reported / was communicated than simply was said.

Grammatically, yes, but in natural English The code was reported by radio or The code was communicated by radio sounds better.

Turkish bildirmek often covers a range that includes:

• report
• notify
• announce
• communicate

The best English translation depends on context. If this is military, police, emergency, or operations language, reported by radio is often the most natural.

Telsiz usually refers specifically to a radio set or walkie-talkie, especially in contexts like police, military, security, or field operations.

So telsizle bildirildi strongly suggests communication over radio rather than by phone or internet.

Yes, Turkish word order is flexible, but the neutral order here is very natural.

The basic pattern is:

• Kod = subject
• telsizle = means/instrument
• bildirildi = verb

Turkish often places the verb at the end.

Other orders are possible for emphasis, for example:

• Telsizle kod bildirildi.
• Kod bildirildi telsizle. (less neutral, more marked)

But Kod telsizle bildirildi is a normal, clear sentence.

It is in the definite past tense with passive meaning.

The ending -di usually expresses a completed action in the past, often something presented as a fact.

So bildirildi means:

• was reported
• was communicated

It refers to a completed event in the past.

A simple active version would be:

• Birisi kodu telsizle bildirdi. = Someone reported the code by radio.

Or, if the subject is known:

• Görevli kodu telsizle bildirdi. = The officer/official reported the code by radio.

Compare:

• Active: Birisi kodu telsizle bildirdi.
• Passive: Kod telsizle bildirildi.

It is one common passive marker, but not the only form you will see.

Turkish passive markers often appear as:

• -ıl / -il / -ul / -ül
• sometimes -n / -ın / -in / -un / -ün, depending on the verb

Which form appears depends on the verb and vowel harmony.

Here:

• bildir- → bildiril-

So in bildirildi, the passive part is -il-.

Roughly:

bil-di-ril-di

Each vowel is pronounced clearly. Turkish pronunciation is usually very regular.

A rough English-friendly guide:

• bil like bill
• di like dee but shorter
• ril with a tapped Turkish r
• di again short and clear

Stress in Turkish is often toward the end, but in many past-tense forms the rhythm can sound fairly even.

Yes, very possibly.

The combination of:

• kod = code
• telsizle = by radio
• bildirildi = was reported/communicated

sounds like something from:

• military communication
• police or security communication
• emergency services
• procedural or official reporting

It is not unnatural in everyday Turkish, but it definitely has a somewhat operational or official feel.
