A jövő fontos.

A is the Hungarian definite article, meaning the.

In A jövő fontos, A jövő means the future.

A quick note:

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

So:

• a jövő = the future
• az iskola = the school

In Hungarian, the verb to be is often omitted in the present tense, third person singular.

So English:

• The future is important.

becomes Hungarian:

• A jövő fontos.

This is completely normal. Hungarian does not need a separate word for is here.

Compare:

• Én fontos vagyok. = I am important.
• Te fontos vagy. = You are important.
• Ő fontos. = He/She is important.

Notice that in the third person singular, there is no van in this kind of sentence.

Jövő means future.

It comes from the verb jön meaning to come, so historically it is related to the idea of what is coming.

Depending on context, jövő can function as:

• a noun: future
• an adjective: coming, next

Examples:

• A jövő fontos. = The future is important.
• jövő hét = next week
• jövő év = next year

In your sentence, jövő is a noun.

A rough pronunciation guide is:

• j sounds like English y in yes
• ö is a rounded front vowel, somewhat like German ö or French eu
• vő has a long ő, which is the long version of ö

So jövő is approximately: yuh-vuhh, but with rounded ö/ő vowels that English does not really have.

More carefully:

• jö ≈ yö
• vő ≈ vő, with a longer vowel

The accents matter:

• ö and ő are not the same as o or ó
• ő is longer than ö

Because fontos is the predicate adjective here.

Hungarian often structures this kind of sentence like:

• subject + adjective

So:

• A jövő fontos. literally looks like:
• The future important.

This is the normal way to say The future is important in Hungarian.

Fontos means important.

In this sentence, it stays in its basic form. Hungarian adjectives do not change for:

• gender
• singular/plural of the subject in this kind of sentence

So:

• A jövő fontos. = The future is important.
• A könyvek fontosak. = The books are important.

Notice that when the subject is plural, the adjective can take a plural form:

• fontosak = important for plural subjects

But with singular jövő, the singular fontos is correct.

Also, Hungarian has no grammatical gender, so there is no difference like important / importante / importante for masculine/feminine.

Yes. Fontos a jövő is also correct.

Both mean The future is important, but the emphasis is slightly different.

• A jövő fontos. → neutral, topic-first: As for the future, it is important.
• Fontos a jövő. → more emphasis on important

Hungarian word order is flexible, and it often reflects focus or emphasis, not just grammar.

So both are grammatical, but the most neutral version for a learner is:

• A jövő fontos.

Not in this exact sentence.

In present tense, third person singular, Hungarian normally leaves out van in simple equational or descriptive sentences:

• A jövő fontos. not
• A jövő van fontos. ✘

But van does appear in other situations, for example:

1. Different persons

   • Én fontos vagyok. = I am important.
   • Te fontos vagy. = You are important.

2. Location/existence

   • A könyv az asztalon van. = The book is on the table.

3. Other tenses

   • A jövő fontos lesz. = The future will be important.
   • A jövő fontos volt. = The future was important.

So the absence of is here is a special feature of the present-tense third-person pattern.

Yes, they are very important.

Hungarian spelling marks vowel quality and vowel length very consistently.

In jövő:

• ö is a different vowel from o
• ő is the long version of ö

Changing or omitting the accents can change pronunciation and sometimes meaning. So you should learn the word as:

• jövő not
• jovo
• jövő
• jövö

Hungarian accents are not optional decoration; they are part of the spelling of the word.

Yes, absolutely.

It is:

• grammatical
• natural
• complete

Even though English requires is, Hungarian does not need it here, so the sentence is fully finished as it stands:

• A jövő fontos.

A native speaker would understand it as a normal statement.

No. Hungarian does not have grammatical gender in nouns or adjectives.

That means:

• jövő is not masculine or feminine
• fontos does not change for gender

This is often easier for English speakers than languages like French or German.

So you do not need to learn separate gender forms for this sentence.
