Metraj keşif bedelini etkiledi.

It follows the very common Turkish Subject–Object–Verb order:

• Metraj = the subject
• keşif bedelini = the direct object
• etkiledi = the verb

So structurally, it is:

[Subject] [Object] [Verb]
Metraj keşif bedelini etkiledi.

That is the most neutral, standard word order in Turkish.

Metraj usually refers to measurement, quantity takeoff, or calculated quantities, especially in construction, engineering, or cost-estimation contexts.

So in this sentence, it is probably not just abstract measurement in a general sense, but something more technical, like:

• measured quantities
• quantity calculations
• takeoff figures

The exact English translation depends on context, but it is a technical noun.

Keşif bedeli is a technical expression, often used in construction, public works, engineering, or valuation contexts.

A practical meaning is usually:

• estimated cost
• cost estimate
• appraised amount
  depending on context

Even though keşif by itself can mean discovery in everyday Turkish, in technical contexts it can refer to surveying, inspection, or estimation work. So translating it word-for-word would be misleading here.

This is one of the most important grammar points in the sentence.

The dictionary/base form here is:

• keşif bedeli

But in the sentence, this noun phrase is the definite direct object, so it takes the accusative ending.

Step by step

• Base compound: keşif bedeli
• Accusative form: keşif bedelini

Why does the ending look like -ni?

Because bedeli already contains a suffix, and when another vowel-initial suffix is added, Turkish inserts a buffer n:

• bedeli
  • -(y)ı/i/u/ü → bedelini

So bedelini means roughly the estimated cost as the specific thing being affected.

Because keşif bedeli is a noun compound.

In Turkish, when one noun modifies another in this kind of compound, the second noun often takes the 3rd person possessive suffix:

• araba kapısı = car door
• okul müdürü = school principal
• keşif bedeli = estimated cost / appraisal amount

So the -i in bedeli is not the accusative ending by itself. It is part of the noun-compound structure.

Then, when the whole expression becomes a definite direct object, the accusative is added on top of that, giving:

• bedeli → bedelini

This is a very common pattern in Turkish and can be confusing at first.

The clearest clue is the ending on bedelini.

In Turkish, a definite direct object usually takes the accusative marker. That is what marks keşif bedelini as the object.

So:

• Metraj = subject
• keşif bedelini = object
• etkiledi = verb

In English, word order does a lot of this work. In Turkish, case endings often make the roles clearer.

Etkiledi is the simple past tense (also called the definite past in many Turkish grammar books).

Breakdown:

• etkile- = to affect
• -di = past tense

So etkiledi means:

• affected

Because the subject is third person singular (metraj), no extra personal ending is needed beyond that.

Turkish does not have articles like English a/an and the.

Instead, Turkish often shows definiteness in other ways, especially through:

• context
• word order
• case marking

In this sentence, the object keşif bedelini has the accusative ending, which strongly suggests a specific/definite object. That is why English usually translates it with the:

• the estimated cost
• the appraisal amount

So Turkish does not say the directly, but the grammar still signals definiteness.

Yes. Turkish word order is flexible, although the original sentence is the most neutral version.

For example, you could also say:

• Keşif bedelini metraj etkiledi.

This still means the same basic thing, because keşif bedelini is marked as the object.

But changing the order changes the focus or emphasis:

• Metraj keşif bedelini etkiledi.
  Neutral statement.
• Keşif bedelini metraj etkiledi.
  Extra focus on the estimated cost.

So the original version is the most natural if you are just stating the fact plainly.

Yes:

• metraj = measurement / quantity takeoff
• keşif bedel-i-ni = estimate cost-(compound ending)-ACC
• etkile-di = affect-PAST

A very literal gloss would be:

Measurement the-estimated-cost affected.

More natural English would be something like:

• The quantity takeoff affected the estimated cost.
• The measurements affected the estimated cost.

The best translation depends on the technical context.
