Azáltal, hogy kijavíttatjuk a féklámpát, már nem találunk benne hibát.

Azáltal, hogy is a common Hungarian structure meaning by doing X, through the fact that..., or by means of the fact that....

In this sentence, it introduces the method or means by which the result is achieved:

• Azáltal, hogy kijavíttatjuk a féklámpát = By having the brake light repaired

The hogy connects azáltal to a full clause. Hungarian often uses a full clause here where English might prefer an -ing form.

So the pattern is:

• azáltal, hogy + clause

For example:

• Azáltal, hogy többet gyakorlok, fejlődöm. = By practicing more, I improve.

It contains several parts:

• ki- = a verbal prefix
• javít = repair / correct
• -tat/-tet = causative suffix, meaning have something done or make someone do something
• -juk = we with a definite object

So:

• javítjuk = we repair it
• javíttatjuk = we have it repaired
• kijavíttatjuk = we have it repaired/fixed fully

The double tt appears because the stem already ends in t:

• javít
  • tat -> javíttat

This is a very typical Hungarian way of saying that the subject does not do the repair personally, but arranges for someone else to do it.

No. kijavíttatjuk usually means we have it repaired, not we repair it ourselves.

That is the key function of the causative suffix -tat/-tet.

Compare:

• kijavítjuk a féklámpát = we repair the brake light
• kijavíttatjuk a féklámpát = we have the brake light repaired

So the sentence implies that we arrange for the repair.

Because it is the direct object of kijavíttatjuk.

• a féklámpa = the brake light
• a féklámpát = the brake light as the thing affected by the action

Even though the verb means have something repaired, the thing being repaired is still the direct object, so it takes -t.

Because its object is definite:

• a féklámpát = the brake light

In Hungarian, if the direct object is definite, the verb usually takes the definite conjugation.

So:

• kijavíttatunk egy féklámpát = we have a brake light repaired
• kijavíttatjuk a féklámpát = we have the brake light repaired

The -juk ending shows we + definite object.

Because the object here is hibát, which is indefinite.

• hibát = a fault / any fault
• a hibát = the fault

Hungarian chooses the verb conjugation based on whether the direct object is definite or indefinite.

So:

• nem találunk benne hibát = we do not find any fault in it
• nem találjuk benne a hibát = we do not find the fault in it

The sentence uses the indefinite version because it is talking about fault of any kind, not one specific identified fault.

benne means in it.

It refers back to a féklámpát. In English, you might say in it or more naturally with it, depending on context.

Hungarian often uses valamiben hibát talál literally find fault in something.

So:

• benne hibát találni = to find fault in it

This is a very natural Hungarian expression.

Because hibát talál valamiben is a standard Hungarian expression meaning:

• to find a fault in something
• to detect a problem in something
• sometimes even to criticize something

Here it is used in the practical, mechanical sense: there is no defect/problem found in the brake light.

Structure:

• hibát = the fault/problem
• találunk = we find
• benne = in it

So literally: we find fault in it.

már nem means no longer or not anymore.

So:

• nem találunk benne hibát = we do not find a fault in it
• már nem találunk benne hibát = we no longer find a fault in it

It suggests a change from an earlier situation: before, there was a fault, or at least a detectable problem; now there is not.

The prefix ki- often adds a sense of out, completely, or thoroughly, but with verbs of correcting or repairing it is often best understood as part of the established verb.

Compare:

• javít = repair, improve, correct
• kijavít = correct, fix properly, repair fully

In many contexts, kijavít sounds more natural than plain javít when a fault is being removed.

So kijavíttatjuk suggests that the brake light gets properly fixed.

Possibly, depending on nuance, but it would not be exactly the same stylistically.

Both ki- and meg- can appear with repair verbs, but they do not always feel identical.

Very roughly:

• megjavíttatjuk = we have it repaired/fixed
• kijavíttatjuk = we have the fault corrected / have it fixed up properly

In many real contexts, speakers might choose one or the other naturally depending on habit and nuance. The form in your sentence strongly matches the idea that a fault has been corrected so that no defect can now be found.

Because Azáltal, hogy... introduces a subordinate clause, and Hungarian normally separates such clauses with a comma.

So the structure is:

• Azáltal, hogy kijavíttatjuk a féklámpát,
• már nem találunk benne hibát.

The first part gives the means; the second part gives the result.

Yes, but not in a rigid English-like way. Hungarian word order is flexible and often reflects emphasis.

This sentence is structured naturally as:

1. means/method first: Azáltal, hogy kijavíttatjuk a féklámpát
2. result second: már nem találunk benne hibát

That makes the logic very clear:

• By having the brake light repaired -> we no longer find a fault in it

A different order would be possible in some contexts, but this version is smooth and neutral.

The -juk in kijavíttatjuk and the -unk in találunk both show first person plural: we.

So the same subject runs through both parts:

• we have the brake light repaired
• we no longer find fault in it

Hungarian often leaves the pronoun mi unstated, because the verb ending already tells you the subject.
