A terhelés a tranzakcióhoz kapcsolódik.

Because Hungarian uses the definite article a / az much like English the.

• a terhelés = the load / the charge
• a tranzakcióhoz = to the transaction

Hungarian often uses the article where English would also use the, so having it twice here is completely normal.

A small extra point:

• a is used before consonant sounds
• az is used before vowel sounds

So you get:

• a tranzakció
• az autó

The ending -hoz means roughly to, toward, or connected to in this kind of structure.

So:

• tranzakció = transaction
• tranzakcióhoz = to the transaction

This is called a case ending. Hungarian usually adds endings to nouns instead of using separate prepositions like English does.

The basic set here is:

• -hoz
• -hez
• -höz

Which one you use depends mostly on vowel harmony.

Examples:

• asztalhoz = to the table
• emberhez = to the person
• székhez = to the chair
• tükörhöz = to the mirror

In your sentence, tranzakció takes -hoz, giving tranzakcióhoz.

kapcsolódik means is connected, relates, or is linked.

In this sentence, it expresses the idea that the load/charge is related to the transaction.

The dictionary form is kapcsolódni, which means to be connected / to connect oneself / to relate to.

So:

• kapcsolódni = to be connected
• kapcsolódik = it is connected / it relates

This is a very common Hungarian verb in formal or technical language.

Because Hungarian does not need a separate verb to be here.

In English, we say:

• is connected

But in Hungarian, kapcsolódik already contains the full verbal idea:

• kapcsolódik = is connected / relates

So there is no need to add another word for is.

This is different from sentences like:

• A terhelés fontos. = The load is important.

In the present tense, Hungarian often leaves out is in simple adjective or noun sentences. But in your example, the main verb is not to be anyway — it is kapcsolódik.

Terhelés is the subject of the sentence.

It is in the nominative form, which is the basic dictionary form of the noun.

So:

• A terhelés = the load / the charge
• this is the thing doing the action of being connected

The structure is basically:

• A terhelés = subject
• a tranzakcióhoz = complement with case ending
• kapcsolódik = verb

Yes, Hungarian word order is more flexible than English word order.

The sentence as given:

• A terhelés a tranzakcióhoz kapcsolódik.

is a natural neutral order, especially in explanatory or formal language.

You could also say:

• A terhelés kapcsolódik a tranzakcióhoz.

That is also grammatical, but it may sound slightly different in rhythm or emphasis.

In Hungarian, word order often reflects topic and focus, not just grammar. The version you were given is a very normal way to present the information:

• topic: A terhelés
• then the phrase it relates to: a tranzakcióhoz
• verb at the end: kapcsolódik

Because kapcsolódik belongs to a group of Hungarian verbs whose 3rd person singular form ends in -ik.

So:

• kapcsolódni = infinitive
• kapcsolódik = he/she/it is connected

This -ik is part of the verb form, not a separate ending with a meaning like English -s.

Many common Hungarian verbs behave this way, for example:

• lakik = he/she lives
• tetszik = he/she/it pleases / you like it
• érkezik = he/she/it arrives

For learners, the most useful thing is simply to memorize kapcsolódni → kapcsolódik as a verb pair.

Here it is intransitive.

That means it does not take a direct object. Instead, it typically combines with a case-marked phrase such as:

• -hoz / -hez / -höz = to
• sometimes other constructions depending on meaning

So in your sentence:

• a tranzakcióhoz is not a direct object
• it is a noun with a case ending showing what the subject is connected to

This is why you do not say something like a tranzakciót kapcsolódik here.

This is a very useful distinction.

• kapcsolódik valamihez = is connected to something / relates to something
• kapcsol valamit valamihez = connects something to something

So:

• A terhelés a tranzakcióhoz kapcsolódik.
  = The load/charge is connected to the transaction.

But:

• A rendszer a terhelést a tranzakcióhoz kapcsolja.
  = The system connects the load/charge to the transaction.

So kapcsolódik is the intransitive form, while kapcsol is the transitive one.

A rough pronunciation guide would be:

• tranzakcióhoz ≈ tran-zak-tsee-oh-hoz

A few helpful points:

• ció sounds roughly like tsee-oh
• h is clearly pronounced
• ó is a long vowel, so it is held a bit longer than o
• hoz sounds like hoz, with a clear h

Also, Hungarian stress is almost always on the first syllable:

• TRAN-zak-ció-hoz

Yes, it can.

Terhelés is a noun formed from terhel and often means:

• load
• burden
• charge
• debit
• stress / strain depending on context

In technical, financial, legal, or database-related language, the exact meaning depends heavily on the context.

So even if the English translation has already been given, it is good to know that terhelés is a fairly broad noun and not limited to only one English word.

Also, the ending -és is a common noun-forming ending in Hungarian, often creating a noun related to an action or process.

It sounds mostly neutral to formal.

The verb kapcsolódik is very common in:

• technical descriptions
• written explanations
• business or IT contexts
• formal speech

In casual conversation, people might sometimes choose other wording depending on context, but this sentence itself is perfectly normal Hungarian.

It has the feel of a statement you might see in:

• documentation
• a report
• banking or software text
• an explanatory note
