Kat malikleri kurulu yönetim planını değiştirdi.

Because değiştirmek means to change something, while değişmek means to change or to undergo change by itself.

• değişmek = to change, to become different
• değiştirmek = to change something, to alter something

In this sentence, the subject changed the management plan, so Turkish uses the transitive verb değiştirmek.

Breakdown:

• değiştir- = change/alter
• -di = past tense
• implied he/she/it ending = 3rd person singular

So değiştirdi = changed.

Because Turkish normally prefers Subject–Object–Verb word order.

Here the parts are:

• Kat malikleri kurulu = subject
• yönetim planını = object
• değiştirdi = verb

So the structure is:

[Subject] [Object] [Verb]

That is the most neutral and natural order in Turkish. English usually puts the verb earlier, but Turkish commonly saves it for the end.

It is a noun phrase meaning a kind of board/council. It is built as a chain of Turkish noun compounds.

You can think of it in steps:

1. kat maliki = apartment-unit owner / condominium owner
2. kat malikleri = apartment-unit owners
3. kat malikleri kurulu = board of apartment-unit owners

So the whole phrase functions as one subject.

Because Turkish noun compounds often make the second noun take a special ending, usually -(s)ı / -(s)i / -(s)u / -(s)ü.

So:

• kurul = board, council
• kat malikleri kurulu = the board of the apartment owners

That -u is not the accusative here. It is the compound/possessive ending that commonly appears on the second noun in this kind of structure.

Compare:

• yönetim planı = management plan
• öğrenci evi = student house / dorm-style house
• şehir merkezi = city center

Same pattern.

Because malikleri is part of another noun compound:

• kat maliki = unit owner / floor owner
• kat malikleri = unit owners

Here again, the second noun in the compound takes that compound ending:

• malik = owner
• kat maliki = owner of a unit/apartment

Then it is pluralized:

• kat malikleri = owners of the units/apartments

So this sentence contains a nested compound:

• kat malikleri
• kat malikleri kurulu

Because in Turkish noun compounds, the first noun is often left in a basic, dictionary-like form.

So:

• kat maliki literally looks like floor/apartment owner
• it does not need to become plural just because the meaning is plural later

This is very normal in Turkish. The first noun often works almost like a classifier or category label.

Because it is the definite direct object of the verb.

In Turkish, a specific direct object usually takes the accusative case. But since yönetim planı is already a noun compound, the object form becomes yönetim planını.

Breakdown:

• yönetim planı = management plan
• yönetim planı-nı = the management plan

That extra -nı is the accusative ending here. The n is a buffer consonant.

So:

• yönetim planı = management plan
• yönetim planını değiştirdi = changed the management plan

Yes.

• yönetim = management, administration
• plan = plan
• plan-ı = management plan
  Here -ı is the compound ending in yönetim planı
• planı-nı = the management plan
  Here the second -ı is the accusative, and n is inserted for pronunciation/grammar

So the full form is:

yönetim + plan-ı + n-ı

This is why learners often feel there are two endings on the word. In a sense, there are.

Because the subject is not just the owners. The subject is Kat malikleri kurulu, meaning the board/council of the owners.

The head noun is kurul = board, which is grammatically singular. So the verb is singular too:

• kurul ... değiştirdi = the board changed

Even though the board is made up of many people, Turkish treats the grammatical subject here as a singular collective body.

No. Turkish does not have articles like English a/an and the.

Whether something is understood as definite or indefinite depends on context and grammar.

Here, definiteness is shown partly by the object marking:

• yönetim planını with accusative strongly suggests the management plan

So Turkish expresses that meaning without using a separate word for the.

Because Turkish often uses noun compounds instead of an English-style of structure.

So instead of building it as a full genitive phrase, Turkish often prefers a compact compound:

• kat malikleri kurulu

This is a very normal and idiomatic way to name institutions, boards, plans, offices, and official bodies.

A learner may expect something more literally like the board of the apartment owners, but Turkish often packages that meaning into a compound structure instead.

Yes, Turkish word order is flexible, but the neutral order is the one you see here.

Neutral:

• Kat malikleri kurulu yönetim planını değiştirdi.

A different order could be used for emphasis, for example if you want to stress yönetim planını. But in ordinary statements, subject + object + verb is the safest pattern.

So the given sentence is the most straightforward standard version.

In değiştirdi, the ğ is not pronounced like a hard English g.

Very roughly:

• değiştirdi sounds something like deyiştirdi or deiştirdi, depending on accent and speed

The ğ usually lengthens or smooths the sound rather than adding a strong consonant.

So don’t pronounce it like deg-ishtirdi with a hard g. That would sound unnatural.

-di is the past tense marker.

So:

• değiştirir = changes / does change
• değiştirdi = changed

Because of vowel harmony and consonant changes, the past tense can appear as:

• -dı
• -di
• -du
• -dü and sometimes with t instead of d

Here it appears as -di.

A useful literal breakdown is:

• kat malikleri kurulu = apartment-owners board
• yönetim planını = management plan-ACC
• değiştirdi = changed

So a very literal gloss would be:

Apartment-owners board the management plan changed.

That is not good English, but it helps show the Turkish grammar:

• subject first
• object marked
• verb last
