A nő vizet visz a gyereknek.

A is the Hungarian definite article, equivalent to English the.

• a nő = the woman
• a gyereknek = to/for the child

Hungarian has two forms of the definite article:

• a before consonant sounds
• az before vowel sounds

So here it is a, because nő and gyerek begin with consonants.

Also, Hungarian articles do not show gender. The same a/az is used for masculine, feminine, and neuter nouns, because Hungarian has no grammatical gender.

Because vizet here means water in a general, non-specific sense.

Hungarian often uses a bare noun with mass nouns like víz (water), kenyér (bread), tej (milk) when you mean some water, not a particular, already-identified water.

So:

• vizet visz = carries/brings water
• a vizet viszi = carries/brings the water

This difference is important, because it also affects the verb form.

Because vizet is the accusative form of víz.

In Hungarian, the direct object usually takes the ending -t. Since water is the thing being carried, it is the direct object.

• base form: víz = water
• accusative: vizet = water as the object

This noun does not just add a simple -t; its form changes a little:

• víz → vizet

That is normal in Hungarian. Some nouns insert a vowel or change slightly when endings are added.

The ending -nak/-nek is the dative ending. It often means to or for someone.

So:

• gyerek = child
• gyereknek = to the child / for the child

Hungarian chooses between -nak and -nek by vowel harmony. Since gyerek has front vowels, it takes -nek.

So the sentence has:

• vizet = the thing being carried
• a gyereknek = the recipient

Because Hungarian verbs have two main conjugation patterns:

• indefinite conjugation
• definite conjugation

Here the object is vizet, which is indefinite or non-specific, so the verb uses the indefinite form:

• visz = he/she carries/takes/brings

If the object were definite, the verb would usually be definite too:

• A nő a vizet viszi a gyereknek. = The woman is carrying the water to the child.

So the choice between visz and viszi depends on the direct object.

Its core meaning is closer to carry/take.

Hungarian makes an important distinction between:

• visz = takes/carries something away from a reference point
• hoz = brings something toward a reference point

In English, the best translation can depend on context. That is why visz may sometimes be translated as brings, especially if English is focusing on the destination.

But if you want the most literal basic idea here, visz is closer to takes/carries.

Hungarian word order is flexible, and it often shows topic and emphasis, not just subject-verb-object order.

This sentence is a very natural neutral pattern:

• A nő = topic, what the sentence is about
• vizet visz a gyereknek = what is said about her

A bare indefinite object like vizet often appears directly before the verb in a neutral sentence.

Other word orders are possible, but they can change the emphasis. For example:

• A nő a gyereknek visz vizet.
  This can put a bit more attention on the child as the recipient.

So the given order is normal, but not the only possible one.

Yes. The Hungarian dative often covers both ideas.

So a gyereknek can mean:

• to the child
• for the child

Which one sounds best in English depends on the situation:

• if the woman is physically moving the water toward the child, to the child is natural
• if the water is intended for the child's use, for the child may also fit

Hungarian does not always force you to choose between those two as strictly as English sometimes does.

A few sounds here are especially important:

• gy in gyereknek is a single consonant sound, somewhat like a soft dy
• ő in nő is a long front rounded vowel, similar to German ö if you know it
• the final sz in visz is pronounced like English s

A rough guide:

• nő ≈ a long nö sound
• visz ≈ vis
• gyereknek ≈ dye-rek-nek, but with a softer first sound than normal English dy

Also, Hungarian stress is normally on the first syllable of each word:

• A NŐ
• VI-zet
• VISZ
• a GYE-rek-nek
