יש לי יותר ביטחון כשאני מדברת עברית.

Hebrew usually does not use a verb equivalent to English to have in the present tense.

So instead of saying something like I have more confidence, Hebrew says:

• יש לי = literally there is to me
• together, it means I have

In this sentence:

• יש לי יותר ביטחון = I have more confidence

This יש + ל־ pattern is extremely common in Hebrew:

• יש לי זמן = I have time
• יש לך שאלה = You have a question
• יש להם כסף = They have money

יותר means more.

So:

• יותר ביטחון = more confidence

It is used for comparison or increase, just like English more:

• יותר טוב = better / more good
• יותר גדול = bigger / larger
• יותר זמן = more time

In this sentence, יותר modifies ביטחון.

ביטחון can mean several related things depending on context:

• confidence
• security
• safety

In this sentence, it clearly means confidence.

Examples in other contexts:

• יש לי ביטחון עצמי = I have self-confidence
• מערכת הביטחון = the security establishment / defense system
• ביטחון אישי = personal safety / sense of security

So the word itself is broad, and context tells you which meaning fits.

Because מדברת is the feminine singular form of speaking in the present tense.

Hebrew present-tense verbs agree with gender and number. For the verb לדבר (to speak):

• אני מדבר = I speak / I am speaking (male speaker)
• אני מדברת = I speak / I am speaking (female speaker)

So this sentence is being said by a woman or girl.

If a man were saying it, the sentence would be:

• יש לי יותר ביטחון כשאני מדבר עברית.

Good question. In Hebrew, the present tense often does not identify the person clearly enough by itself.

For example:

• מדברת means speaking in feminine singular
• but it could mean I am speaking, you are speaking (feminine), or she is speaking, depending on context

So Hebrew often includes the pronoun to make the subject clear:

• כשאני מדברת = when I speak / when I’m speaking

Without אני, the sentence would sound incomplete or unclear in most normal contexts.

כשאני means when I.

It is made of:

• כש־ = when
• אני = I

So:

• כשאני מדברת עברית = when I speak Hebrew / when I’m speaking Hebrew

You will see כש־ attached directly to many words:

• כשאתה בא = when you come
• כשהיא לומדת = when she studies
• כשאנחנו מגיעים = when we arrive

Sometimes learners also see כאשר, which is a more formal version of when.

It can mean either one, depending on context.

Hebrew present tense often covers both:

• simple present: I speak
• present progressive: I am speaking

So:

• כשאני מדברת עברית can mean:
  • when I speak Hebrew
  • when I’m speaking Hebrew

In this sentence, both are natural in English. The exact best translation depends on context.

In Hebrew, the verb לדבר usually takes the language directly, without a preposition.

So Hebrew says:

• לדבר עברית = to speak Hebrew
• לדבר אנגלית = to speak English
• לדבר צרפתית = to speak French

English often uses no preposition too: speak Hebrew.
But in this sentence, English might also naturally say when I speak Hebrew, not when I speak in Hebrew.

So עברית here is simply the object/complement of מדברת.

Yes, this word order is completely natural.

The sentence is:

• יש לי יותר ביטחון = I have more confidence
• כשאני מדברת עברית = when I speak Hebrew

So the full meaning is:

• I have more confidence when I speak Hebrew

Hebrew could sometimes rearrange parts for emphasis, but this version is very standard and natural.

For example, you might also hear:

• כשאני מדברת עברית, יש לי יותר ביטחון.

This means the same thing, but starts with when I speak Hebrew for emphasis or flow.

ביטחון is masculine.

That matters in some cases, especially with adjectives and numbers.
In this sentence, יותר does not change form for gender, so you do not see any obvious effect here.

For example:

• ביטחון עצמי גבוה = high self-confidence
  Here גבוה is masculine singular because ביטחון is masculine.

But in your sentence:

• יותר ביטחון = more confidence

יותר stays the same.

Yes. That would mean I have more self-confidence and is often even more explicit.

Compare:

• יש לי יותר ביטחון = I have more confidence / more sense of confidence
• יש לי יותר ביטחון עצמי = I have more self-confidence

Both are good, but ביטחון עצמי specifically means self-confidence.

The main change would be in the present-tense verb.

If a man says it:

• יש לי יותר ביטחון כשאני מדבר עברית.

If we say we and the group is masculine or mixed:

• יש לנו יותר ביטחון כשאנחנו מדברים עברית.

If we say we and the group is all feminine:

• יש לנו יותר ביטחון כשאנחנו מדברות עברית.

If you are speaking to a woman:

• יש לך יותר ביטחון כשאת מדברת עברית.

If you are speaking to a man:

• יש לך יותר ביטחון כשאתה מדבר עברית.

So the key part that changes is the form of מדבר / מדברת / מדברים / מדברות and sometimes the pronoun.

Yes, absolutely. It sounds natural and idiomatic.

A native speaker might also say close variations such as:

• אני מרגישה יותר ביטחון כשאני מדברת עברית.
  = I feel more confident when I speak Hebrew.

• יש לי יותר ביטחון לדבר בעברית.
  = I have more confidence to speak in Hebrew / speaking Hebrew.

• כשאני מדברת עברית, אני מרגישה יותר בטוחה בעצמי.
  = When I speak Hebrew, I feel more self-confident.

But your original sentence is perfectly natural and clear.
