A főnök ma az irodában van.

Hungarian has one definite article with two forms: a and az.

• a is used before a word that begins with a consonant:
  a főnök
• az is used before a word that begins with a vowel:
  az irodában

So this is a pronunciation rule, not a meaning difference. It is a bit like English a/an, except Hungarian a/az means the, not a/an.

irodában breaks down like this:

• iroda = office
• -ban = in

So irodában literally means in the office.

This is a very common Hungarian pattern: instead of using a separate word like English in, Hungarian often adds a suffix directly to the noun.

Because final a often lengthens to á before certain suffixes.

So:

• iroda → irodában
• not irodaban

This is a normal sound change in Hungarian. You will see the same kind of thing with many nouns ending in a or e:

• szoba → szobában
• mese → mesében

So the stem is still iroda, but the final vowel lengthens when the suffix is added.

This is because of vowel harmony, a very important Hungarian pattern.

The suffix meaning in has two common forms:

• -ban
• -ben

Words with mostly back vowels usually take -ban.
Words with front vowels usually take -ben.

iroda contains back vowels (o, a), so it takes -ban:

• irodában

Compare:

• házban = in the house
• kertben = in the garden

Learning vowel harmony early is very helpful, because many Hungarian suffixes change this way.

van is the 3rd person singular form of to be: is.

It is needed here because the sentence says where someone is:

• A főnök az irodában van. = The boss is in the office.

In Hungarian, the present-tense is is often left out in sentences like:

• A főnök fáradt. = The boss is tired.
• A főnök orvos. = The boss is a doctor.

But when you say that someone or something is somewhere, van is normally used:

• A főnök az irodában van.

So this is a good sentence to remember as a location pattern.

In standard Hungarian, not in this sentence.

• Correct: A főnök ma az irodában van.
• Not standard as a full sentence: A főnök ma az irodában.

Because this is a location sentence, van is expected.

In casual speech, people may drop things in very informal contexts, but as a learner, you should keep van here.

Hungarian word order is more flexible than English, and it is strongly connected to topic and emphasis.

In A főnök ma az irodában van, the structure is quite natural and neutral:

• A főnök = topic, what we are talking about
• ma az irodában van = what we are saying about him

Putting van at the end sounds normal here. But other word orders are also possible if the emphasis changes, for example:

• Ma a főnök az irodában van.
  Emphasis more on today
• Az irodában van a főnök.
  Emphasis more on where he is

So the given order is not the only possible one, but it is a very natural one.

Because Hungarian often does not use subject pronouns unless they are needed for emphasis or contrast.

Here, the subject is already clearly stated:

• A főnök = the boss

So there is no need to add ő (he/she).

Even when there is no noun subject, Hungarian often still omits the pronoun:

• Ma az irodában van. = He/She is in the office today.

The context usually tells you who is meant.

This is a very important difference:

• irodában = in the office
  location, no movement
• irodába = into the office / to the office
  movement toward the inside

So:

• A főnök az irodában van. = The boss is in the office.
• A főnök az irodába megy. = The boss is going into the office.

A useful shortcut:

• -ban/-ben = in
• -ba/-be = into

A few key points:

• Hungarian stress is usually on the first syllable of the word.
• So főnök is stressed like FŐ-nök.

The vowels are the tricky part:

• ö is a short front rounded vowel
• ő is the long version of ö

If you know German or French, they may help:

• ö is somewhat like German ö
• ő is a longer version of that sound

So főnök has two rounded front vowels, with the first one long.

Also, Hungarian spelling is very regular, so once you learn the vowel sounds, pronunciation becomes much easier than in English.

No. ma means today, and its position can move depending on what you want to emphasize.

The given sentence:

• A főnök ma az irodában van.

is a natural, neutral way to say it.

But you can also say:

• Ma a főnök az irodában van.
• A főnök az irodában van ma.

These are not all identical in feel. Hungarian word order often signals what is new, important, contrasted, or already known. As a beginner, it is best to learn the given order first and then notice how word order shifts in real examples.
