A videóhívás hamarosan kezdődik.

A is the Hungarian definite article, meaning the.

Hungarian has two forms of the definite article:

• a before consonant sounds
• az before vowel sounds

Since videóhívás starts with v, the correct form is a:

• a videóhívás = the video call

Videóhívás is a compound noun:

• videó = video
• hívás = call, calling

So videóhívás literally means video call.

Hungarian very often forms compounds by writing the parts together as one word.

Hívás is a noun made from the verb hív, which means to call.

So:

• hív = to call
• hívás = a call / calling

This is very common in Hungarian: a verb can become a noun with endings like -ás or -és.

Hamarosan means soon or shortly.

It is an adverb, so it describes when the action happens. In this sentence, it tells us when the video call will begin.

It is a very natural word in neutral Hungarian, especially for announcements and system messages.

This is one of the most useful things to notice in the sentence.

• kezd usually means starts something / begins something
• kezdődik means begins / starts as an event happening

So:

• A tanár kezdi az órát. = The teacher starts the lesson.
• Az óra kezdődik. = The lesson is starting / begins.

In your sentence, the video call is the thing that is beginning, so kezdődik is the natural choice.

Not in a literal reflexive sense.

Even though English speakers may feel that kezdődik looks like start itself, it is best to learn it simply as the normal intransitive verb to begin / to start for events.

So just think of:

• kezdeni = to start something
• kezdődni = to begin, to get started

Grammatically, kezdődik is present tense.

But Hungarian often uses the present tense for near-future or scheduled future events, just like English can do in sentences such as:

• The meeting starts soon
• The train leaves at six

So A videóhívás hamarosan kezdődik. is naturally understood as:

• The video call is starting soon
• The video call will start soon

Yes, it could be different.

The given order is a neutral, natural statement:

• A videóhívás hamarosan kezdődik.

You could also say:

• Hamarosan kezdődik a videóhívás.

That version puts more attention on soon.

Hungarian word order is flexible, but it is not random. It often changes depending on what is already known, what is being emphasized, and what the speaker wants to highlight.

Sometimes, but it changes the feel.

With a, the sentence sounds like a normal full sentence about a specific video call:

• A videóhívás hamarosan kezdődik.

Without the article, it can sound more like:

• a headline
• a label
• a system notification style
• a more abrupt announcement

So omitting the article is possible in some contexts, but a videóhívás is the most standard full-sentence version.

A simple pronunciation guide is:

• A → short, like o in British lot for many speakers
• videóhívás → VI-deh-oh-HII-vaash
• hamarosan → HA-ma-ro-shan
• kezdődik → KEZ-doe-dik

A few useful points:

• Hungarian stress is usually on the first syllable of each word.
• The accented vowels are longer:
  • ó
  • í
• s is pronounced like English sh
• sz would be like English s, but there is no sz in this sentence

It is in the nominative case, which is the basic dictionary form and is typically used for the subject of the sentence.

Here, a videóhívás is the subject: it is the thing that is beginning.

Hungarian nominative singular usually has no special ending, so the noun appears in its plain base form.

Yes, kezdődik belongs to the group of verbs whose third-person singular form ends in -ik.

For beginners, the most important thing is simply to learn the full verb:

• kezdődni = to begin

The -ik pattern does affect some conjugated forms, but in this sentence you mainly just need to recognize kezdődik as:

• it begins
• it is starting

So it matters, but not in a way that changes the basic meaning here.
