Kiürítjük a konténert.

It breaks down like this:

• ki- = a verbal prefix meaning out, often suggesting completion
• ürít = to empty
• -jük = we in the present tense, with a definite object

So kiürítjük means something like we empty it out or we are emptying it.
In this sentence, the it is a konténert.

Because Hungarian uses a special verb ending when the object is definite.

Here, a konténert means the container, so it is a specific, known object. That is why Hungarian uses the definite conjugation:

• kiürítjük a konténert = we empty the container

Compare:

• kiürítünk egy konténert = we empty a container

So -jük tells you:

• the subject is we
• the tense is present
• the object is definite

That is because of vowel harmony.

Hungarian often has two versions of the same ending:

• -juk
• -jük

The verb ürít contains front vowels (ü, í), so it takes the front-vowel version:

• ürítjük

If a verb had back vowels, you would more likely see -juk instead.

Because it is the direct object of the verb, and Hungarian marks direct objects with the accusative ending -t.

So:

• konténer = container
• konténert = container as the thing being acted on

In English, word order usually shows the object. In Hungarian, the -t ending helps show it clearly.

a means the.

Hungarian has two forms of the definite article:

• a before a consonant
• az before a vowel

Since konténer starts with k, a consonant, the sentence uses:

• a konténert

If the next word began with a vowel, you would use az.

The prefix ki- often gives the idea of out or out completely.

So:

• ürít = empty
• kiürít = empty out, clear out completely

In this sentence, ki- makes the action sound more complete, like fully emptying the container, not just partially dealing with it.

Hungarian verbal prefixes are very important, because they often change the meaning in ways similar to English phrasal verbs like clear out, take out, or fill up.

The verb form is present tense.

However, in Hungarian, the present tense can often be used for the future if the context makes that clear.

So Kiürítjük a konténert can mean things like:

• We are emptying the container
• We empty the container
• We will empty the container

Context decides which one is meant.

For example:

• Holnap kiürítjük a konténert. = We’ll empty the container tomorrow.

Yes, it can be separated.

In a neutral, positive statement, the verbal prefix usually stays directly attached to the verb:

• Kiürítjük a konténert.

But in other sentence types, it often moves away, especially with negation or focus:

• Nem ürítjük ki a konténert. = We are not emptying the container.
• A konténert ürítjük ki. = It is the container that we are emptying out.

So the attached form here is the normal neutral pattern.

Yes. Hungarian word order is flexible, but different orders give different emphasis.

The original sentence:

• Kiürítjük a konténert.

is a neutral way to say it.

You may also see:

• A konténert kiürítjük. = As for the container, we’ll empty it.
• A konténert ürítjük ki. = stronger focus on the container

So the meaning stays similar, but the information structure changes.

No. In Hungarian, accent marks such as é and í usually show vowel length, not stress.

So in:

• konténer
• kiürítjük

the marks tell you the vowels are longer, not that those syllables are stressed.

Hungarian stress normally falls on the first syllable of the word:

• KON-té-ner-t
• KI-ü-rí-tjük

That is very different from English, where spelling often does not clearly show stress.

No, it is a loanword, but it behaves like a normal Hungarian noun.

So it can take Hungarian endings just like many other nouns:

• konténer
• konténert
• konténerben
• konténerből

This is very common in Hungarian: borrowed words still follow Hungarian grammar.
