Rezistența este importantă.

Rezistența means the resistance, not just resistance.

In Romanian, the definite article is usually attached to the end of the noun instead of being a separate word like English the.

• rezistență = resistance
• rezistența = the resistance

So the sentence is using the definite form of the noun.

That is a normal feature of Romanian grammar. Romanian usually puts the definite article at the end of the noun.

For feminine singular nouns, the definite article is often -a.

Examples:

• casă = house
• casa = the house

With rezistență, the same thing happens:

• rezistență = resistance
• rezistența = the resistance

This is one of the big differences between Romanian and English.

Yes, rezistență is a feminine noun.

A very common clue is the ending -ă in the singular dictionary form:

• rezistență

Many Romanian nouns ending in -ă are feminine, though not every noun follows a simple rule 100% of the time.

You can also see that it is feminine because the adjective agrees with it:

• importantă = feminine singular
• not important or importante

So the sentence gives you two clues that the noun is feminine.

Because Romanian adjectives must agree with the noun in gender and number.

Since rezistența is feminine singular, the adjective must also be feminine singular:

• masculine singular: important
• feminine singular: importantă
• masculine plural: importanți
• feminine / neuter plural: importante

So:

• Rezistența este importantă.

If the noun were masculine singular, you would use important instead.

Este is the 3rd person singular form of the verb a fi, meaning to be.

So here:

• este = is

The structure is very straightforward:

• Rezistența = the resistance
• este = is
• importantă = important

So the sentence literally follows the pattern: Subject + is + adjective

In normal standard Romanian, no—you usually keep este in sentences like this.

So:

• Rezistența este importantă. = normal and correct

You may sometimes hear shortened spoken forms like:

• Rezistența-i importantă.

That -i is a contracted form of e / este in speech.

But in clear, standard written Romanian, este is the safe form to use.

The letter ă is a special Romanian vowel. It is a short, central sound, somewhat like the a in English sofa or the unstressed sound uh, though not exactly the same in every accent comparison.

In this sentence:

• rezistență
• importantă

The final ă is not a normal English a sound like in cat or cake. It is much more neutral and reduced.

This vowel is extremely common in Romanian, so it is worth getting used to early.

ț is pronounced like ts, similar to the sound at the end of English cats.

So rezistența contains:

• ț = ts

A rough pronunciation guide would be something like:

• re-zis-TEN-tsa

That comma-like mark under the letter matters:

• ț is not the same as plain t

The usual stress is:

• rezisTENța
• imporTANtă

So the stressed syllables are:

• TEN
• TAN

A rough guide:

• re-zis-TEN-tsa ES-te im-por-TAN-tuh

Romanian stress is not always fully predictable, so it is helpful to learn it word by word.

In this sentence, importantă comes after este, because it is part of the predicate:

• Rezistența este importantă.
• literally: The resistance is important.

That is the normal pattern.

Romanian adjectives can sometimes come before or after nouns when they directly modify them, but here the adjective is not sitting next to the noun as an attribute. It comes after the verb este, so the structure is simply:

• noun + verb to be
  • adjective

Yes, but the basic sentence:

• Rezistența este importantă.

is the most neutral and natural.

You could change the order for emphasis, for example:

• Importantă este rezistența.

That sounds more marked, as if you are emphasizing important or contrasting resistance with something else.

For ordinary use, stick with:

• Rezistența este importantă.

Yes. It is a very clear cognate.

• English: important
• Romanian: important / importantă

They come from the same broader Latin-based vocabulary, which is why they look so similar.

This is helpful for learners, but remember that Romanian changes the ending to match gender and number, so you will not always see the exact same form.

If you wanted to say simply Resistance is important, you would usually use:

• Rezistența este importantă in many general contexts, especially when talking about the concept in a broad way

But if you want the bare indefinite noun form, you might also encounter:

• Rezistență as the base noun

In practice, Romanian often uses the definite form in places where English may use either a definite or a more general abstract noun. So learners should not always expect article use to match English exactly.

That means Rezistența este importantă can often sound very natural even in a general statement.

Here is the breakdown:

• Rezistența — noun, feminine singular, definite form
• este — verb, 3rd person singular present of a fi (to be)
• importantă — adjective, feminine singular

So grammatically, it is:

• subject: Rezistența
• copular verb: este
• predicate adjective: importantă
