kanozyo ha yuukan desu.

は marks the topic of the sentence. In 彼女は勇敢です, the speaker is saying something about her.

A natural way to think about it is:

• 彼女は = As for her, ...
• 勇敢です = (she) is brave

So the sentence has a topic-comment structure:

• topic: 彼女
• comment: 勇敢です

Both は and が can sometimes translate to she in English sentences, but they do different jobs.

• は introduces the topic and often sounds more neutral or contrastive.
• が identifies or emphasizes the subject more strongly.

So:

• 彼女は勇敢です。 = She is brave. / As for her, she is brave.
• 彼女が勇敢です。 would sound more like She is the brave one or It is she who is brave, depending on context.

In a simple textbook sentence like this, は is the most natural choice.

勇敢 is a na-adjective in Japanese.

That means it behaves differently from an i-adjective like 大きい or 高い.

Examples:

• 勇敢な人 = a brave person
• 彼女は勇敢です = She is brave

So even though it translates like an English adjective, grammatically it belongs to the na-adjective group.

Because な is only used when a na-adjective comes directly before a noun.

For example:

• 勇敢な女性 = a brave woman

But in this sentence, 勇敢 is not modifying a noun. It is part of the predicate:

• 彼女は勇敢です。

So you do not say 勇敢なです. That would be incorrect.

です is the polite ending here. It makes the sentence sound courteous and complete.

In this sentence:

• 彼女は勇敢です。 = polite
• 彼女は勇敢だ。 = plain style

You can think of です here as doing a job similar to is, but it is not always a perfect one-to-one match with English to be. It mainly marks the sentence as polite and helps complete the predicate.

Yes. 彼女は勇敢だ is grammatically correct.

The difference is style:

• 彼女は勇敢です。 = polite
• 彼女は勇敢だ。 = plain / less formal

Use です in polite conversation, class, or when speaking respectfully. Use だ in casual speech, writing, or certain narrative styles.

Not always. 彼女 can mean:

• she
• girlfriend, depending on context

In 彼女は勇敢です, it most naturally means she, because it is being used as the topic of a sentence describing someone.

Still, learners should know that 彼女 can also mean girlfriend in other situations.

Not as often. Japanese often omits pronouns when the meaning is clear from context.

So while 彼女は勇敢です is a perfectly good example sentence, in real conversation a speaker might simply say:

• 勇敢です。
• あの人は勇敢です。 = That person is brave.
• use the person’s name instead

This is one reason Japanese can feel less pronoun-heavy than English.

Yes, but Japanese word order works differently from English.

This sentence follows a very common pattern:

• topic + は + description + です

So:

• 彼女 = topic noun
• は = topic marker
• 勇敢 = description
• です = polite sentence ending

English says She is brave, with the verb in the middle. Japanese often puts the main description before the final ending, so the sentence ends with です.

Even though it is written with the kana は, when it is used as the topic particle, it is pronounced wa.

So:

• 彼女は勇敢です
• pronounced roughly: kanojo wa yuukan desu

This is one of the first pronunciation exceptions Japanese learners meet.

勇敢 is pronounced ゆうかん.

A rough romanization is:

• yūkan or yuukan

Breakdown:

• ゆう = yuu
• かん = kan

The ゆう part has a long vowel sound, so it is a little longer than just ゆ.

Yes. Because it is a na-adjective, it can modify a noun with な.

Examples:

• 勇敢な人 = a brave person
• 勇敢な兵士 = a brave soldier
• 勇敢な彼女 = the brave her / brave girlfriend, though this exact phrase depends on context

So:

• before a noun: 勇敢な
• at the end of a sentence: 勇敢です / 勇敢だ

It is a real and useful word, but it can sound a bit formal, literary, or descriptive depending on context.

Other words can also express similar ideas, such as:

• 大胆 = bold
• 度胸がある = to have guts
• 勇気がある = to have courage

But 勇敢 is completely natural and correct, especially in writing, descriptions, or textbook examples.
