Az ültetőláda nagy.

Hungarian has two forms of the definite article: a and az.

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

Since ültetőláda begins with ü, which is a vowel, the correct article is az.

So:

• a ház = the house
• az alma = the apple
• az ültetőláda = the planter box

In Hungarian, the verb to be is usually left out in the third person singular and plural in the present tense when talking about simple descriptions or identity.

So instead of saying a separate word for is, Hungarian simply says:

• Az ültetőláda nagy. = The planter box is big.

Compare:

• Én nagy vagyok. = I am big.
• Te nagy vagy. = You are big.
• Az ültetőláda nagy. = The planter box is big.

In the third person present tense, the is/are is normally omitted.

Here, nagy is not directly modifying the noun inside a noun phrase; it is the predicate adjective of the sentence.

So the sentence structure is:

• Az ültetőláda = the subject
• nagy = the description about the subject

This is like saying:

• The planter box — big

which Hungarian uses to mean The planter box is big.

If you want the adjective directly before the noun, like the big planter box, then Hungarian would say:

• a nagy ültetőláda

So:

• a nagy ültetőláda = the big planter box
• az ültetőláda nagy = the planter box is big

It is one compound word, which is very common in Hungarian.

It is made up of:

• ültető = planting / planter
• láda = box / crate

Together, ültetőláda means something like planter box, planting box, or raised planter depending on context.

Hungarian often combines words into compounds where English might use two words.

For example:

• virágcserép = flower pot
• könyvesbolt = bookshop
• ültetőláda = planter box

A rough pronunciation guide is:

ÜL-te-tuh-LAA-da

A few important points:

• ü is a front rounded vowel, somewhat like the u in French tu or German über
• ő is a long version of a similar rounded vowel
• á is a long vowel, pronounced clearly and held a bit longer than a

Hungarian pronunciation is quite regular, and the stress is always on the first syllable:

ÜL-te-tő-lá-da

No. In Hungarian, adjectives do not agree with nouns in gender, and Hungarian also has no grammatical gender like masculine/feminine/neuter.

So nagy stays the same:

• a ház nagy = the house is big
• az asztal nagy = the table is big
• a láda nagy = the box is big

Even with plural nouns, predicate adjectives usually stay unchanged:

• A ládák nagyok. = The boxes are big.

Here the plural is shown on the adjective because it is part of the predicate, but there is still no gender agreement to worry about.

Yes. That is also grammatical.

Hungarian word order is flexible and often changes the focus or emphasis.

• Az ültetőláda nagy. = neutral statement, The planter box is big.
• Nagy az ültetőláda. = puts more emphasis on big, something like The planter box is big or The planter box is indeed big.

So both are correct, but the first one is the more neutral, basic sentence for a learner.

It is in the nominative form, which is the basic dictionary form of the noun.

There is no special ending here because it is the subject of the sentence:

• Az ültetőláda nagy. = The planter box is big.

If the noun had another role, it would often take a case ending. For example:

• Látom az ültetőládát. = I see the planter box.

Here -t marks the direct object.

You would make the noun plural and also use the plural form of the predicate adjective:

• Az ültetőládák nagyok. = The planter boxes are big.

Changes:

• ültetőláda → ültetőládák = plural noun
• nagy → nagyok = plural predicate adjective

This is worth noticing, because Hungarian handles plural adjectives differently depending on the structure.

Hungarian often uses the definite article when talking about a specific, identifiable thing, just like English does in the planter box.

So az ültetőláda means the planter box, referring to a particular one.

If you wanted a planter box is big in a more general or indefinite sense, you could say:

• Egy ültetőláda nagy.

But in many contexts, that sounds less natural unless you specifically mean one planter box or a certain planter box. The version with az is the most straightforward if a specific planter box is being talked about.
