Videóhívásban beszélünk anélkül, hogy lefoglalnánk a telefonfülkét.

Videóhívásban comes from videóhívás, meaning video call. The ending -ban is the inessive case, which usually means in.

So the phrase is literally something like in a video call, even though natural English usually says on a video call. This is a good reminder that Hungarian case endings do not always match English prepositions one-for-one.

Also, it is -ban rather than -ben because of vowel harmony: videóhívás has back vowels, so it takes the back-vowel form of the suffix.

Hungarian often leaves out the article in adverbial expressions when the noun describes the situation, medium, or mode rather than a specific individual thing.

Here videóhívásban means roughly by video call / in a video-call setting, so the sentence is not really focusing on a particular video call as a separate object. That is why the bare noun sounds natural.

If you added an article, the phrase would feel more specifically tied to one identifiable call.

Yes. Hungarian has no separate tense that works exactly like the English present progressive. The plain present tense often covers both:

• we talk
• we are talking

So beszélünk can mean either one, depending on context. In this sentence, English would most naturally use we are talking or we talk, depending on the wider situation.

The form itself is:

• beszél = speak, talk
• beszélünk = we speak / we are speaking

Anélkül, hogy is a very common Hungarian structure meaning without doing something when what follows is a whole clause with its own verb.

So:

• anélkül = without that / without it
• hogy = that

But you should learn anélkül, hogy as one unit. In natural English, it usually becomes without plus an -ing form or a full clause.

A similar example is:

• Elment anélkül, hogy elköszönt volna.
• He left without saying goodbye.

Because after anélkül, hogy, Hungarian normally uses the conditional. This is a grammar rule of the construction.

So even though lefoglalnánk is literally a conditional form, here it does not sound especially hypothetical in the way English would reserve does. In English, we usually just say without reserving / without occupying.

The ending -nánk shows:

• conditional mood
• first person plural: we

And it is -nánk rather than -nénk because foglal has back vowels.

The base verb foglal can mean occupy, take up, book, or reserve, depending on context. With the prefix le-, lefoglal often means something like:

• reserve
• book
• occupy
• tie up
• monopolize

In this sentence, with a telefonfülkét, it most likely means take up or occupy the phone booth so that others cannot use it. So the idea is not necessarily a formal reservation system; it may simply mean using the booth in a way that keeps it unavailable.

A telefonfülkét is the direct object of lefoglalnánk, so it takes the accusative ending -t.

The basic form is:

• a telefonfülke = the phone booth

The object form is:

• a telefonfülkét = the phone booth, as the thing being occupied/reserved

Notice that the final e becomes é before the accusative -t. That is a normal pattern with many Hungarian nouns ending in -e or -a.

Yes, grammatically it goes with a definite object, because a telefonfülkét means the phone booth.

What may confuse learners is that in the conditional, first person plural, the definite and indefinite forms happen to look the same:

• indefinite: foglalnánk
• definite: foglalnánk

So in this sentence, the form lefoglalnánk does not visibly show the difference, but because the object is definite, it is functioning with a definite object.

Hungarian usually leaves out subject pronouns when the verb ending already makes the subject clear.

Both verbs here already show first person plural:

• beszélünk = we speak / we are speaking
• lefoglalnánk = we would reserve / we would occupy

So adding mi would usually only be done for emphasis or contrast, such as we, not someone else.

Because hogy introduces a subordinate clause, and Hungarian normally marks that with a comma.

In the fixed structure anélkül, hogy, the comma is standard:

• anélkül, hogy lefoglalnánk a telefonfülkét

So the comma is not optional stylistic punctuation here; it is part of normal Hungarian spelling.

Yes, Hungarian word order is fairly flexible, but changes in order often change focus or emphasis.

The original sentence presents the main statement first:

• Videóhívásban beszélünk, then
• anélkül, hogy lefoglalnánk a telefonfülkét

That sounds natural and straightforward. You could also put the anélkül, hogy... clause first:

• Anélkül, hogy lefoglalnánk a telefonfülkét, videóhívásban beszélünk.

That version gives a bit more emphasis to the without occupying the phone booth idea. So yes, the word order can change, but not completely freely without affecting nuance.
