Amikor hűvös van, a gyerek gyorsan öltözik, és sapkát is vesz fel.

Amikor means when and introduces a time clause.

So:

• Amikor hűvös van = When it is cool
• a gyerek gyorsan öltözik... = the child gets dressed quickly...

In Hungarian, just like in English, a clause starting with amikor is often followed by the main clause.

In Hungarian, weather and general conditions are often expressed with van (is / there is).

So:

• Meleg van. = It is warm.
• Hideg van. = It is cold.
• Hűvös van. = It is cool.

English uses it is, but Hungarian does not use a dummy subject like it here. The verb van is enough.

Also note that in present tense, Hungarian often drops van in normal adjective sentences like A ház nagy (The house is big), but in weather/condition expressions such as hűvös van, van is kept.

Hungarian does not need a subject like English it in expressions such as:

• Esik. = It is raining.
• Sötét van. = It is dark.
• Hűvös van. = It is cool.

English requires a grammatical subject, even when it does not refer to anything real. Hungarian usually does not.

A is the definite article, meaning the.

So:

• a gyerek = the child / the kid

Hungarian often uses the definite article in places where English also would. Without the article, gyerek would sound more like child in a more general or indefinite sense, and it would not fit this sentence as naturally.

Also note:

• a is used before consonant sounds
• az is used before vowel sounds

For example:

• a gyerek
• az alma

Hungarian usually leaves out subject pronouns when they are not needed, because the verb form already shows the person and number, or the subject noun is already present.

Here the subject is explicitly stated as a gyerek, so adding ő (he/she) would be unnecessary:

• a gyerek öltözik = the child is getting dressed

Hungarian often avoids repeating information that is already clear.

Öltözik means gets dressed / is dressing.

It comes from the verb öltözik, which is an intransitive verb: it focuses on the person dressing themself.

Compare:

• öltözik = to get dressed
• öltöztet valakit = to dress someone

So:

• A gyerek öltözik. = The child is getting dressed.
• Az anya öltözteti a gyereket. = The mother is dressing the child.

This is a very common distinction in Hungarian.

Because gyorsan is the adverb form, meaning quickly.

• gyors = quick, fast (adjective)
• gyorsan = quickly, fast (adverb)

Here it describes how the child gets dressed, so Hungarian uses the adverb:

• gyorsan öltözik = gets dressed quickly

This -an / -en / -on / -ön type of ending is a common way to form adverbs in Hungarian, though not every adverb follows exactly the same pattern.

The ending -t marks the direct object in Hungarian.

So:

• sapka = hat
• sapkát = hat as the object of the verb

In this sentence, the child is putting on a hat, so hat is the thing being acted on. That is why Hungarian uses the accusative ending:

• sapkát vesz fel = puts on a hat

This object marking is very important in Hungarian grammar.

Felvesz is a verbal-prefix verb.

• vesz = takes
• fel = a prefix that often adds the idea of up, but in many expressions it creates a new meaning
• felvesz can mean put on (clothes), among other meanings depending on context

With clothing, felvesz means to put on:

• kabátot vesz fel = puts on a coat
• sapkát vesz fel = puts on a hat

So even though it looks like take + up, together it functions as the normal Hungarian verb for put on in this context.

In Hungarian, verbal prefixes often separate from the verb in certain sentence patterns.

The basic dictionary form is:

• felvesz = puts on

But in the sentence:

• sapkát is vesz fel

the prefix comes after the verb. This can happen when the focus falls on another part of the sentence, here especially sapkát is.

Very roughly:

• Felvesz egy sapkát. = neutral: He/She puts on a hat.
• Sapkát is vesz fel. = focus on a hat too

This kind of prefix movement is extremely common in Hungarian and is something learners see all the time.

Is means also / too.

So:

• sapkát is vesz fel = also puts on a hat / puts on a hat too

It adds the idea that the hat is an additional item. The child is not only getting dressed in general, but is also putting on a hat.

Hungarian is usually comes right after the word it belongs to. Here it belongs to sapkát, so it means:

• a hat too
• not, for example, also gets dressed in a general sense

Compare:

• A gyerek is öltözik. = The child also gets dressed.
• A gyerek sapkát is vesz fel. = The child puts on a hat too.

The placement of is matters.

Yes, but not with exactly the same emphasis.

A more neutral version would be:

• ...és sapkát is felvesz.

or even:

• ...és felvesz egy sapkát.

When the prefix is placed after the verb, as in vesz fel, it usually reflects a certain information structure or focus pattern. In your sentence, the split form helps highlight sapkát is.

So both forms are possible in Hungarian, but they are not always interchangeable in tone or emphasis.

Because Amikor hűvös van is a subordinate clause, and Hungarian normally separates that from the main clause with a comma.

So the structure is:

• Amikor hűvös van, = subordinate time clause
• a gyerek gyorsan öltözik, és sapkát is vesz fel. = main clause

This is similar to English:

• When it is cool, the child gets dressed quickly...

Hungarian punctuation often follows clause boundaries quite clearly.

Hungarian often uses a comma before és when it connects larger clause-like parts, especially when each part has its own predicate or when the sentence is relatively structured.

Here we have:

• a gyerek gyorsan öltözik
• és sapkát is vesz fel

Both parts contain a verb, so the comma is natural in Hungarian punctuation.

English is often less likely to use a comma before and in a simple sentence, but Hungarian punctuation rules are a bit different.
