Skutečný výsledek je důležitý.

Here is the structure:

• skutečný = real / actual / genuine
• výsledek = result
• je = is
• důležitý = important

So the pattern is:

adjective + noun + is + adjective

More literally:

real result is important

In natural English, you would usually say The real result is important or The actual result is important.

Because Czech adjectives must agree with the noun they describe.

In this sentence, the noun is výsledek, which is:

• masculine
• singular
• nominative (the subject form)

So both adjectives take the matching form:

• skutečný výsledek = real result
• výsledek je důležitý = the result is important

A very important point for learners: even the adjective after je still agrees with the subject.

So:

• výsledek je důležitý = masculine singular
• not důležitá or důležité

Výsledek is masculine inanimate.

That matters because gender affects:

• adjective endings
• some pronouns
• past tense forms
• case endings

Here, because výsledek is masculine singular, the adjectives are:

• skutečný
• důležitý

If the noun were feminine, the adjective forms would change. For example:

• Skutečná odpověď je důležitá.
  The real answer is important.

If the noun were neuter:

• Skutečné rozhodnutí je důležité.
  The real decision is important.

Because Czech has no articles.

There is no direct equivalent of English a / an / the in normal Czech grammar.

So:

• výsledek can mean a result, the result, or just result
• the exact meaning depends on context

In this sentence, English usually needs the or sometimes the actual, but Czech does not.

That is completely normal:

• Skutečný výsledek je důležitý.
• literally: Real result is important
• natural English: The real result is important

Je is the 3rd person singular form of the verb být = to be.

So:

• já jsem = I am
• ty jsi = you are
• on/ona/ono je = he/she/it is

Since výsledek is singular, Czech uses je:

• výsledek je důležitý = the result is important

Unlike in Russian, Czech normally does not drop the present-tense verb to be in sentences like this. So you need je here.

Not completely. Czech word order is more flexible than English.

The neutral order here is:

Skutečný výsledek je důležitý.

But other orders are possible for emphasis, for example:

• Důležitý je skutečný výsledek.
  = What is important is the real result.

That does not change the basic meaning much, but it changes focus and emphasis.

English relies more on word order for grammar. Czech relies more on endings, so it can move words around more freely.

Still, for learners, the given order is a very good neutral one.

Because it describes the noun výsledek, not the manner of an action.

• důležitý = important → adjective
• důležitě = importantly → adverb

Here the meaning is:

• The result is important

So Czech uses the adjective:

• výsledek je důležitý

You would use důležitě only if you meant something like:

• He spoke importantly
  = Mluvil důležitě.

So in your sentence, důležitý is the correct form.

It often means real, actual, genuine, or true-to-fact, depending on context.

In this sentence, skutečný most naturally means:

• real
• actual

So:

• Skutečný výsledek = the real result / the actual result

It is related to skutečnost, which means reality or fact.

Be careful: English true is often better translated by pravdivý or sometimes pravý, depending on the context.

So skutečný is not always a perfect one-to-one match for English true.

Because predicate adjectives with být normally agree with the subject in the nominative.

So:

• výsledek = nominative singular
• důležitý = nominative singular masculine

That is why the sentence is:

• Skutečný výsledek je důležitý.

This is very common in Czech:

• Dům je velký. = The house is big.
• Kniha je zajímavá. = The book is interesting.
• Město je krásné. = The city is beautiful.

So although důležitý comes after the verb, it still agrees with the subject.

A rough pronunciation guide:

• Skutečný ≈ SKOO-tech-nee
• výsledek ≈ VEE-sle-dek
• je ≈ ye
• důležitý ≈ DOO-le-zhi-tee

A few key sounds:

• č = like ch in church
• ž = like s in measure
• ý = a long ee sound
• ů = a long oo sound
• j = English y sound

Also, Czech stress is usually on the first syllable of the word:

• SKU-teč-ný
• VÝ-sle-dek
• DŮ-le-ži-tý

You negate je by changing it to není:

• Skutečný výsledek není důležitý.
  = The real result is not important.

This is the normal way to negate a sentence with být in the present tense.

The adjectives would change to match the noun.

Examples:

• Skutečná odpověď je důležitá.
  feminine singular
  The real answer is important.

• Skutečné rozhodnutí je důležité.
  neuter singular
  The real decision is important.

• Skutečné výsledky jsou důležité.
  plural
  The real results are important.

Notice that both the first adjective and the final adjective change, and in the plural the verb changes too:

• je = is
• jsou = are

This is one of the central patterns in Czech grammar: adjectives and verbs reflect the noun they go with.
