אני מקשיבה לצליל של המילה החדשה ומנסה לבטא אותה כמו המורה.

Because the speaker is feminine singular. In Hebrew present tense, verbs agree with the subject in gender and number.

• אני מקשיב = I am listening / I listen (male speaker)
• אני מקשיבה = I am listening / I listen (female speaker)

In this sentence, אני is understood as I spoken by a woman or girl.

Good question. With מקשיבה, the feminine ending is easy to see. But מנסה is one of those present-tense forms where the masculine singular and feminine singular are often written the same in everyday Hebrew.

So in this sentence:

• מקשיבה clearly shows a feminine speaker
• מנסה also fits a feminine speaker here, even though it looks the same as the masculine form in regular spelling

Learners often expect both verbs to show gender in the same obvious way, but Hebrew does not always work that neatly.

Hebrew often leaves out subject pronouns in past and future tense, because the verb already shows the person clearly. But in the present tense, the verb usually shows gender and number, not person.

So מקשיבה by itself means something like listening or is listening, but not clearly I am listening unless context tells you that.

That is why אני is very natural here. It makes the subject explicit.

Because Hebrew usually writes short connecting words as prefixes. The letter ו־ means and.

So:

• ומנסה = and tries / and am trying

This is completely normal. Hebrew does not usually write and as a separate word the way English does.

Because the verb להקשיב takes the preposition ל־, just like English listen to takes to.

So:

• להקשיב ל־ = to listen to
• אני מקשיבה לצליל = I am listening to the sound

You do not use a direct object marker here, because צליל is not the direct object of the verb. It comes after the preposition ל־.

Because in Hebrew, the prepositions ב־, כ־, and ל־ usually combine with the definite article ה־.

So:

• ל + הצליל becomes לצליל in normal unpointed writing

That means לצליל can represent either:

• to a sound
• to the sound

Context tells you which one is meant. In this sentence, it is naturally understood as to the sound of the new word.

של means of and is used to show possession or connection.

So:

• צליל של המילה החדשה = the sound of the new word

Hebrew also has another way to express this idea, called the construct form, for example צליל המילה החדשה. But של is extremely common and often feels clearer and more conversational.

Because Hebrew adjectives usually come after the noun, not before it.

So:

• מילה חדשה = a new word
• המילה החדשה = the new word

The adjective must also agree with the noun in:

• gender
• number
• definiteness

Since מילה is feminine singular, the adjective is חדשה. Since the noun is definite (המילה), the adjective is also definite (החדשה).

Because after לנסות / מנסה (to try / trying), Hebrew normally uses an infinitive.

So:

• מנסה לבטא = tries to pronounce
• literally, tries to pronounce

This works very much like English try to pronounce.

אותה is the feminine singular direct-object pronoun, meaning it or her, depending on context.

Here it means it, and it refers back to המילה (the word), which is a feminine noun in Hebrew.

So:

• לבטא אותה = to pronounce it

If the noun were masculine, Hebrew would use אותו instead.

Also, notice that you do not add a separate את before אותה. The form אותה already includes the direct-object idea.

כמו means like or as.

So:

• כמו המורה = like the teacher

The word המורה means the teacher, a specific teacher known from the context. Also, מורה can refer to either a male or a female teacher; the form is the same here.

It can be either. Hebrew present tense often covers both the simple present and the present progressive.

So this sentence can mean:

• I listen to the sound of the new word and try to pronounce it like the teacher
• I am listening to the sound of the new word and trying to pronounce it like the teacher

The exact English choice depends on context, not on a different Hebrew verb form.
