Portalanítjuk a radiátort.

Literally, portalanítjuk means something like we make it dust-free.

It is built from:

• por = dust
• -talan / -telen = without
• -ít = a verb-forming suffix meaning make / render
• -juk = we with a definite object

So portalanítjuk a radiátort is very literally we are making the radiator dust-free, which naturally means we are dusting the radiator or we are removing dust from the radiator.

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

So:

• radiátor = radiator
• radiátort = radiator + object ending

In this sentence, the radiator is the thing being dusted, so it takes the accusative ending -t.

A is the Hungarian definite article, meaning the.

So:

• a radiátort = the radiator

Hungarian uses definite and indefinite articles much like English, although not always in exactly the same places. Here, the sentence is talking about a specific radiator, so a is used.

The ending -juk shows two things at once:

• the subject is we
• the verb is in the definite conjugation

Hungarian has two main sets of verb endings:

• indefinite conjugation
• definite conjugation

You use the definite conjugation when the verb has a definite direct object, such as:

• a radiátort = the radiator
• a proper name
• a pronoun like it, him, her
• something with a possessive, like my book

Because the object here is definite, the verb is portalanítjuk, not an indefinite form.

Yes. Then both the article and the verb form would normally change.

You would expect:

• Portalanítunk egy radiátort.

Here:

• egy radiátort = a radiator
• portalanítunk = we dust / we are dusting in the indefinite conjugation

So the definite object a radiátort goes with portalanítjuk, while the indefinite object egy radiátort goes with portalanítunk.

No, not in this sentence. Hungarian usually leaves out subject pronouns when the verb ending already makes the subject clear.

So:

• Portalanítjuk a radiátort. = We are dusting the radiator.

The -juk ending already tells you the subject is we, so mi (we) is unnecessary unless you want emphasis or contrast.

For example:

• Mi portalanítjuk a radiátort. = We are the ones dusting the radiator.

That version sounds more emphatic.

Yes. Hungarian present tense often covers both:

• simple present
• present continuous

So depending on context, this sentence could mean:

• We dust the radiator
• We are dusting the radiator

In real life, context usually makes it clear whether it is a habitual action or something happening right now.

Portalanít is more specific than clean. It focuses on removing dust.

So it is closer to:

• dust
• dust off
• remove dust from

It does not automatically mean a full cleaning in every possible sense. If you wanted a broader idea of cleaning, you might use verbs like:

• tisztít = clean
• kitakarít = clean up / do cleaning

So Portalanítjuk a radiátort specifically suggests dealing with dust on the radiator.

Yes, Hungarian word order is flexible, but different orders can shift the emphasis.

The neutral sentence is:

• Portalanítjuk a radiátort.

This is a normal, straightforward way to say it.

You could also say:

• A radiátort portalanítjuk.

That puts more focus on the radiator, perhaps contrasting it with something else:

• It’s the radiator that we’re dusting.

So the basic meaning stays similar, but the emphasis changes.

The dictionary form is portalanít.

Other useful forms are:

• portalanítani = to dust / to remove dust from
• portalanítok = I dust
• portalanítunk = we dust something indefinite
• portalanítjuk = we dust it / we dust the definite object

When learning Hungarian verbs, it helps to know both the basic dictionary form and how the definite/indefinite forms work.

A rough guide is:

• Portalanítjuk ≈ POR-taw-law-NEET-yook
• a ≈ short aw
• radiátort ≈ RAW-dee-aa-tort

A few key points:

• The stress in Hungarian is always on the first syllable of each word.
• í and á are long vowels.
• j is pronounced like English y in yes.
• ty, gy, ny, etc. are special Hungarian sounds, but this sentence does not contain them.

So the main stresses are:

• PORtalanítjuk
• RAdiátort

No, radiátor is a loanword, ultimately international in character, and it looks very similar to English radiator.

That is common in Hungarian, especially with technical or household nouns. Even though the word is borrowed, it still behaves like a normal Hungarian noun, so it takes Hungarian endings:

• radiátor
• radiátort
• radiátorok
• radiátorban, etc.

Because the word is built by adding suffixes to por.

A helpful way to see it is:

• por = dust
• portalan = dustless
• portalanít = make dustless, remove dust from

The -talan part is attached to the noun stem, and then -ít turns that into a verb.

So the form may look long, but it is actually made of meaningful pieces, which is very typical of Hungarian word-building.
