Olcsó díjcsomagot választok az internet-előfizetéshez.

Because díjcsomagot is the direct object of the verb választok (I choose).

In Hungarian, the direct object usually takes the accusative ending -t. After certain nouns, that ending appears with a linking vowel, so díjcsomag becomes díjcsomagot.

• díjcsomag = fee plan / tariff package
• díjcsomagot = a fee plan / tariff package, as the thing being chosen

So the sentence marks clearly what is being chosen.

Because in Hungarian, an adjective used before a noun usually does not take the same case ending as the noun.

So:

• olcsó díjcsomag = a cheap plan
• olcsó díjcsomagot = a cheap plan (as object)

Only the noun gets the accusative ending here: díjcsomagot.

This is different from some languages where adjectives agree more fully with the noun. In Hungarian, attributive adjectives are much simpler in this respect.

Választok is:

• present tense
• 1st person singular
• from the verb választ = choose

So it means I choose or I am choosing, depending on context.

The ending -ok tells you the subject is I.

This is a very common Hungarian learner question.

Hungarian verbs can use two kinds of conjugation:

• indefinite conjugation
• definite conjugation

Here, választok is the indefinite form.

Why? Because olcsó díjcsomagot is treated as an indefinite / non-specific object: a cheap plan, not the cheap plan.

Compare:

• Olcsó díjcsomagot választok. = I choose a cheap plan.
• Az olcsó díjcsomagot választom. = I choose the cheap plan.

So the sentence uses választok because the object is not definite.

It breaks down like this:

• az = the
• internet-előfizetés = internet subscription
• -hez = to / for

So az internet-előfizetéshez means something like:

• for the internet subscription
• for the internet plan
• to go with the internet subscription

In this sentence, it shows what the cheap package is being chosen for.

The suffix -hoz / -hez / -höz often means to or for, depending on context.

Here it expresses the idea of choosing something for something else:

• választok valamit valamihez = I choose something for something

So:

• az internet-előfizetéshez = for the internet subscription

This is a very natural Hungarian way to show suitability or intended use.

Because of vowel harmony, which is one of the big patterns in Hungarian.

This suffix has three forms:

• -hoz
• -hez
• -höz

The noun előfizetés contains front vowels, so it takes the front-vowel version -hez.

That is why you get:

• előfizetéshez

and not előfizetéshoz.

Because in Hungarian, the definite article stays in front of the noun even when the noun gets a case suffix.

So:

• az előfizetés = the subscription
• az előfizetéshez = to/for the subscription

This is normal Hungarian structure: article + noun + case ending

The case ending goes on the noun, not on the article.

Hungarian has two forms of the definite article:

• a
• az

Use az before a vowel sound, and a before a consonant sound.

Since internet-előfizetés begins with a vowel sound, the correct form is:

• az internet-előfizetéshez

Compare:

• a csomaghoz = to the package
• az előfizetéshez = to the subscription

Hungarian word order is fairly flexible, but it is not random. It often reflects emphasis, topic, and information structure.

In this sentence, putting olcsó díjcsomagot before the verb is very natural. It presents the thing being chosen before the action:

• Olcsó díjcsomagot választok az internet-előfizetéshez.

A different order is possible, but it may sound different in emphasis. For example:

• Az internet-előfizetéshez olcsó díjcsomagot választok.

That version puts more attention on for the internet subscription as the starting point of the sentence.

So the meaning stays close, but the focus can shift.

Because it is a compound noun, and Hungarian spelling often uses a hyphen in longer compounds.

Here:

• internet
  • előfizetés = internet-előfizetés

This helps readability and follows standard Hungarian spelling conventions for longer compound words.

So the hyphen is mainly an orthographic issue, not a grammar issue.

Not quite. Díjcsomag is more specific than a general package.

• díj = fee, charge
• csomag = package, bundle

Together, díjcsomag usually means a pricing plan, tariff package, or service plan—the kind of package you choose for phone, internet, or utilities.

So in this sentence it is not just any package. It is a plan with a certain price structure.
