Az adatokat még egyszer megnézem, mert a cím fontos.

Because adatokat is the direct object form of adatok.

• adat = data item / piece of data
• adatok = data (plural)
• adatokat = the data, as the thing being acted on

The ending -t is the accusative marker, used for direct objects.
Here, the speaker is checking the data, so Hungarian marks data as the object.

You can think of it like this:

• adatok = data
• adatokat = data + “as the object”

The form also includes the plural element, so it is not just -t, but -okat here.

Hungarian has two forms of the definite article:

• a before a consonant sound
• az before a vowel sound

Since adatokat begins with a-, Hungarian uses az:

• az adatok
• az adatokat

This works a bit like English a/an, though it is used for the, not a.

Compare:

• a cím = the title/address
• az adat = the data item

még egyszer means once more, one more time, or again.

Literally:

• még = still / yet / more
• egyszer = once / one time

Together, very often:

• még egyszer = again / once again

So in this sentence it means the speaker will check the data one more time.

megnézem comes from:

• néz = to look
• meg- = a verbal prefix
• -em = I in the definite conjugation

So megnézem means something like:

• I will look at it
• I’ll check it
• I’ll take a look at it

Because the object is definite — az adatokat = the data — Hungarian uses the definite verb ending here.

That is why it is megnézem, not a form from the indefinite conjugation.

The prefix meg- often gives the verb a sense of completion, result, or looking something over as a whole.

Compare:

• nézem = I am looking at it / I watch it
• megnézem = I look it over / I check it / I take a look at it

So megnézem sounds more like a completed action: I’ll check it, rather than just I’m looking at it.

This is a very common pattern in Hungarian verbs with prefixes.

Because Hungarian usually omits subject pronouns when the verb ending already shows the subject.

In megnézem, the ending tells you the subject is I.

So:

• megnézem = I check it / I’ll check it

You could say én megnézem, but én would add emphasis, like I will check it.

Hungarian normally leaves én out unless there is contrast or emphasis.

In Hungarian, the verb to be is often left out in the present tense, third person, when linking a noun to an adjective or another noun.

So:

• a cím fontos = the address/title is important

There is no separate word for is here.

This is completely normal in Hungarian.

Compare:

• A cím fontos. = The address/title is important.
• A cím nem fontos. = The address/title is not important.

But in other tenses, the verb appears:

• A cím fontos volt. = The address/title was important.

Yes, Hungarian word order is more flexible than English word order.

This sentence is natural, but other orders are also possible depending on emphasis and information structure.

Here, Az adatokat comes first, which makes the data the topic: the speaker is talking about the data, and then says what they will do with it.

A different order like:

• Még egyszer megnézem az adatokat.

is also possible and sounds very natural too.

So Hungarian word order is not just about grammar; it is also about what is already known, what is emphasized, and what the speaker wants to highlight.

mert means because.

It introduces the reason:

• Az adatokat még egyszer megnézem = I’ll check the data once more
• mert a cím fontos = because the address/title is important

So the second clause explains why the speaker wants to check the data again.

No. cím can mean several related things depending on context, such as:

• address
• title
• label
• heading

So the exact translation depends on the situation.

In a sentence about data, cím often means address, but in another context it could easily mean title.
