A hozzájárulás fontos.

A is the Hungarian definite article, so it corresponds to the.

Hungarian has two forms:

• a before a consonant
• az before a vowel

Since hozzájárulás starts with h, Hungarian uses a:

• a hozzájárulás

If the next word began with a vowel, you would use az instead.

In Hungarian, the verb to be is usually omitted in the present tense, third person singular/plural when one noun or adjective is linked to another.

So:

• A hozzájárulás fontos. = The contribution/consent is important.

But in other tenses or persons, the verb appears:

• A hozzájárulás fontos volt. = The contribution was important.
• Én fontos vagyok. = I am important.

This is one of the most common patterns English speakers notice in Hungarian.

The exact meaning depends on context. Hozzájárulás can mean things like:

• contribution
• consent
• approval
• authorization

For example:

• in an administrative or legal context, it may mean consent or permission
• in a general discussion, it may mean contribution or input

So this is a word whose best English equivalent depends heavily on the situation.

Yes. It is related to the verb hozzájárul.

• hozzájárul = to contribute / to consent / to agree to
• hozzájárulás = contribution / consent / approval

The ending -ás / -és often turns a verb into a noun naming the action or result of the action.

So learners can think of hozzájárulás as the act/result of hozzájárul.

A rough English-friendly guide is:

HOZZ-aa-yaa-roo-laash

A few useful points:

• stress is always on the first syllable in Hungarian
• á is a long vowel
• j sounds like English y
• s sounds like English sh
• the double zz is pronounced longer than a single z

So the word begins with a stressed HOZZ- sound, not with English-style stress later in the word.

It is in the nominative (the basic dictionary form), because it is the subject of the sentence.

There is no visible case ending here. The structure is simply:

• A hozzájárulás = the contribution/consent
• fontos = important

So literally the sentence is built like The contribution important, with the Hungarian present-tense pattern that leaves out is.

Yes, you can also say Fontos a hozzájárulás.

The version A hozzájárulás fontos is a very natural, neutral order:

• A hozzájárulás is the topic
• fontos gives the new information about it

If you say Fontos a hozzájárulás, you put more emphasis on important. It can sound like:

• The contribution is important
• or more pointedly, What is important is the contribution

So both are grammatical, but the emphasis changes.

In this sentence, no, because the subject is singular.

• A hozzájárulás fontos. = singular
• A hozzájárulások fontosak. = plural

So when the adjective is used as the predicate, it can show plural:

• fontos → fontosak

A useful comparison:

• fontos hozzájárulás = important contribution
• fontos hozzájárulások = important contributions

Here, when the adjective comes directly before the noun, it does not take a plural ending.

Usually, in a normal sentence, A hozzájárulás fontos is the natural form.

Hungarian often uses the definite article with abstract nouns more readily than English does. So even if English might say something like consent is important or contribution is important, Hungarian often still prefers a.

Without the article, Hozzájárulás fontos would sound unusual in ordinary speech. It might only work in a very compressed style, such as a heading, a note, or a slogan-like phrase.

So for everyday Hungarian, stick with:

• A hozzájárulás fontos.
