Öt munkavállaló van az irodában.

In Hungarian, after a number, the noun normally stays singular.

So:

• öt munkavállaló = five employee grammatically, but it means five employees
• not öt munkavállalók

This is a very important difference from English.

More examples:

• két könyv = two books
• három diák = three students
• tíz autó = ten cars

So öt munkavállaló is exactly what you should expect in Hungarian.

With a numbered subject such as öt munkavállaló, Hungarian normally uses a singular verb.

So the standard form is:

• Öt munkavállaló van az irodában.

not:

• Öt munkavállaló vannak az irodában.

This matches the same pattern as the singular noun after the number. Hungarian treats these quantified expressions differently from English.

More examples:

• Két ember van kint. = Two people are outside.
• Három gyerek ül a padon. = Three children are sitting on the bench.

That is a very common question. Hungarian does often omit van in the third person present, but not in every kind of sentence.

It is usually omitted in simple equational or descriptive sentences:

• Péter orvos. = Péter is a doctor.
• Az iroda nagy. = The office is big.

But in existential or locational sentences, van is normally kept:

• Péter az irodában van. = Péter is in the office.
• Öt munkavállaló van az irodában. = There are five employees in the office.

So here van is necessary.

Az irodában means in the office.

It breaks down like this:

• az = the
• iroda = office
• -ban = in

So the core idea is:

• irodában = in office / in the office

The ending -ban / -ben is the Hungarian inessive case, used for being inside something.

Examples:

• a házban = in the house
• a szobában = in the room
• az iskolában = in the school

Hungarian has two forms of the definite article:

• a
• az

The choice depends on the following sound:

• a before a consonant
• az before a vowel

Since iroda begins with the vowel i, the correct form is:

• az iroda
• az irodában

Compare:

• a ház = the house
• a könyv = the book
• az autó = the car
• az iskola = the school

This happens because many Hungarian nouns ending in -a or -e lengthen that final vowel before certain suffixes.

So:

• iroda
  • -ban → irodában
• not irodaban

This is a regular pattern:

• szoba → szobában
• iskola → iskolában
• mese → mesében

So the final a/e often becomes á/é when a suffix is attached.

Because Hungarian normally does not use an indefinite article before a number phrase like this.

So:

• öt munkavállaló = five employees

not something like:

• egy öt munkavállaló

If you want to say the five employees, then you can use the definite article:

• az öt munkavállaló = the five employees

So the sentence as given is an indefinite existential statement: there are five employees in the office.

Yes, you can. Hungarian word order is flexible, but different orders give different emphasis or information structure.

The original:

• Öt munkavállaló van az irodában.

This is a very natural way to present the information.

You can also say:

• Az irodában öt munkavállaló van.

This puts the office first, as the topic: As for the office, there are five employees in it.

So the meaning stays very close, but the emphasis shifts a little. Hungarian word order is not random, but it is much more flexible than English word order.

It is correct and natural, but it sounds a bit formal or administrative.

Munkavállaló is common in:

• official language
• HR language
• contracts
• workplace policies

In everyday speech, people might also use words like:

• alkalmazott = employee
• dolgozó = worker / employee

So Öt munkavállaló van az irodában is perfectly good Hungarian, especially in a formal or neutral context.

A helpful pronunciation guide is:

• Öt
• MUN-ka-vál-la-ló
• van
• az
• I-ro-dá-ban

A few key points:

• Hungarian stress is normally on the first syllable of each word.
• ö is a front rounded vowel, similar to German ö or French eu.
• á is a long vowel.
• ó is also long.

So the rhythm is roughly:

• Öt MUNkavállaló van az IRodában.

If you want to sound natural, keeping the first-syllable stress and the long vowels clear matters a lot.

Yes. In this context, both are possible English translations.

The Hungarian sentence is an existential/locational sentence:

• Öt munkavállaló van az irodában.

Depending on context, English may express it as:

• There are five employees in the office.
• Five employees are in the office.

The first one is usually the more natural default translation in English, but the Hungarian sentence itself works well for either kind of idea, depending on context.
