La resistència és important.

A good approximate pronunciation is:

lah ruh-zees-TEN-see-uh ez eem-por-TANT

A more Catalan-like IPA pronunciation is:

[lə rəzisˈtɛn.si.ə es impuɾˈtan]

A few useful notes:

• La is usually a light lə in many Central Catalan accents.
• resistència has the stress on -tèn-.
• és sounds like ess with a clear e sound.
• important is stressed on the last syllable: imporTANT.

La is the feminine singular definite article, meaning the.

It is used because resistència is a feminine singular noun:

• la resistència = the resistance

Catalan often uses the definite article with abstract nouns more naturally than English does. So even if English might sometimes just say Resistance is important, Catalan commonly says La resistència és important.

You usually learn the gender together with the noun: la resistència, not just resistència.

In this case, it is feminine, so it takes:

• la in the singular
• les in the plural

Examples:

• la resistència
• les resistències

There is no completely reliable rule from the ending alone, although nouns ending in -ència are very often feminine.

It usually means resistance, but the exact sense depends on context. It can refer to:

• physical resistance or endurance
• opposition to something
• electrical resistance
• military or political resistance

So the sentence could mean something like:

• Resistance is important
• Endurance is important

The context tells you which sense is intended.

The accent mark shows both stress and vowel quality.

In resistència, the grave accent è tells you that:

• the stressed syllable is tèn
• the vowel is an open e sound

So the word is stressed like this:

re-sis-TÈN-ci-a

Without the accent, the pronunciation rules would suggest a different stress pattern.

És is the 3rd person singular of the verb ser:

• és = is

The accent helps distinguish it from es, which is a different word used as a pronoun in Catalan.

So:

• és = is
• es = a reflexive/clitic pronoun in other contexts

This accent is very important in writing.

Catalan, like Spanish, often distinguishes between ser and estar.

Here, és is used because important is being presented as a general or essential characteristic:

• La resistència és important = resistance is important

You would not normally use estar here, because this is not a temporary state or location.

So:

• ser = identity, classification, general qualities
• estar = state, condition, location in many contexts

Because important is an adjective with the same form for masculine and feminine singular.

So you get:

• important with masculine singular
• important with feminine singular

Examples:

• El llibre és important.
• La resistència és important.

Only the plural changes:

• important → importants

Examples:

• Els llibres són importants.
• Les resistències són importants.

Yes, you could say És important la resistència, but it sounds a bit different.

• La resistència és important is the most neutral, straightforward statement.
• És important la resistència can sound more emphatic or stylistically marked, as if highlighting important first.

For a learner, the basic pattern to remember is:

subject + verb + adjective

So:

• La resistència = subject
• és = verb
• important = adjective

Normally, no. That would sound unnatural in standard Catalan.

With abstract nouns, Catalan often uses the definite article where English may omit it. So Catalan prefers:

• La resistència és important.

Even though English often says:

• Resistance is important.

This is a very common difference between English and Catalan.

Here, important is an adjective.

It describes the noun resistència, but it appears after the verb és, so it functions as a predicate adjective:

• La resistència = noun phrase / subject
• és = verb
• important = adjective describing the subject

This is similar to English:

• Resistance is important

The plural would be:

Les resistències són importants.

Changes:

• La → Les
• resistència → resistències
• és → són
• important → importants

So Catalan marks plural in several places, not just one.

Usually yes: re-sis-tèn-ci-a.

The ending -cia here is not like English -sha. Catalan keeps the vowels more distinct:

• -ci-a = roughly see-uh

So resistència has five syllables in careful pronunciation:

• re
• sis
• tèn
• ci
• a

In natural speech, some accents may make the final vowels sound lighter, but they are still there.
