A vízhatlan zsák a kenuban van.

Because a is the Hungarian definite article, meaning the.

So:

• A vízhatlan zsák = the waterproof bag
• a kenuban = in the canoe

Hungarian uses the article separately before each definite noun phrase, just like English uses the more than once in a sentence.

A small extra note: Hungarian has two forms of the definite article:

• a before consonant sounds
• az before vowel sounds

So here it is a zsák, a kenuban, because both words begin with consonant sounds.

In Hungarian, adjectives normally come before the noun they describe, just as in English.

So:

• vízhatlan zsák = waterproof bag

This is the normal order.

Also, Hungarian adjectives do not change for gender, and in this kind of phrase they do not take the case ending; the noun does. So you get:

• a vízhatlan zsák
• a vízhatlan zsákban

The ending goes on zsák, not on vízhatlan.

-ban is a case ending meaning in or inside.

So:

• kenu = canoe
• kenuban = in the canoe

Hungarian often expresses meanings like in, on, to, from with endings attached directly to the noun instead of separate prepositions.

Here the sentence uses the inessive ending, which answers the question Where?

Because of vowel harmony.

Hungarian suffixes often have different forms depending on the vowels in the word. For this ending, the two common forms are:

• -ban
• -ben

Words with back vowels usually take -ban, and words with front vowels usually take -ben.

Since kenu contains back vowels, the correct form is:

• kenuban

Compare:

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

Because Hungarian very often uses case endings where English uses prepositions.

English says:

• in the canoe

Hungarian says:

• a kenu-ban

So the idea of in is built into the ending -ban rather than being a separate word.

This is a very common feature of Hungarian grammar.

That is a very common and very good question.

In Hungarian, the 3rd person present form of to be is often omitted in simple identification or description sentences:

• A zsák vízhatlan. = The bag is waterproof.

Here there is no van.

But when you talk about location or existence, Hungarian normally uses van:

• A zsák a kenuban van. = The bag is in the canoe.

So:

• description/identity: often no van
• location/existence: usually van

Because that is a very natural Hungarian word order for a neutral statement of location.

In this sentence:

• A vízhatlan zsák is the topic, what the sentence is about
• a kenuban van says where it is

Hungarian word order is more flexible than English word order, and it is strongly influenced by topic and focus.

So A vízhatlan zsák a kenuban van is a normal way to say The waterproof bag is in the canoe.

You can also change the order for emphasis. For example, putting a kenuban earlier can make the location more prominent.

Because the subject is singular.

• zsák = bag singular
• van = is

If the subject were plural, you would use vannak:

• A vízhatlan zsákok a kenuban vannak. = The waterproof bags are in the canoe.

So:

• singular subject → van
• plural subject → vannak

Because a means the, while egy means a/an or one.

So:

• a vízhatlan zsák = the waterproof bag
• egy vízhatlan zsák = a waterproof bag

Using a suggests that the bag is specific or already known in the context. Using egy would sound less specific.

Hungarian has no grammatical gender.

That means nouns are not divided into masculine, feminine, and neuter the way they are in many European languages. So:

• a does not mean masculine or feminine
• adjectives do not change for gender
• verbs do not change for gender either

That makes phrases like a vízhatlan zsák simpler in this respect than in many Indo-European languages.

A few useful pronunciation points:

• v sounds like English v
• í is a long ee sound
• zs sounds like the s in measure
• á is a long open a
• a in Hungarian is not the same as English a; it is more like a short open vowel
• stress in Hungarian normally falls on the first syllable of the word

So roughly:

• vízhatlan ≈ VEEZH-hot-lon
• zsák ≈ zhaak
• kenuban ≈ KEH-noo-bon

These are only rough English approximations, but they help with the main sounds.
