היא מכירה את הנושא היטב.

היא means she, and here it helps identify who the subject is.

In the present tense, Hebrew verb forms often show gender and number, but not full person as clearly as English does. So מכירה can mean:

• I know / am familiar with (if the speaker is female)
• you know / are familiar with (to one female)
• she knows / is familiar with

Because of that, adding היא makes it clear that the meaning is she.

מכירה is the feminine singular present-tense form, matching היא.

This verb comes from להכיר, which often means to know / be familiar with / recognize.

Here are the present-tense forms:

• מכיר — masculine singular
• מכירה — feminine singular
• מכירים — masculine plural / mixed plural
• מכירות — feminine plural

Since the subject is she, the sentence uses מכירה.

This is a very common question.

Hebrew often distinguishes between:

• להכיר — to be familiar with, to know through acquaintance or experience
• לדעת — to know a fact, know information, know how

So היא מכירה את הנושא היטב suggests that she is very familiar with the subject/topic, perhaps through study, work, or experience.

If you used יודעת, it would sound more like she knows about the subject, but מכירה emphasizes familiarity and command of it.

את is the direct object marker. It does not have an English translation here, but it marks the noun that receives the action of the verb.

In this sentence:

• מכירה = knows / is familiar with
• את הנושא = the subject/topic

Hebrew usually uses את before a definite direct object.

So:

• את הנושא = the subject
• but if it were indefinite, you would usually not use את

For example:

• היא מכירה נושא מעניין = She knows an interesting topic/subject
• היא מכירה את הנושא המעניין = She knows the interesting topic/subject

The prefix ה־ is the Hebrew definite article, meaning the.

So:

• נושא = a subject / a topic
• הנושא = the subject / the topic

Because the object is definite, Hebrew also uses את before it: את הנושא.

נושא can mean subject or topic, depending on context.

For example, it could refer to:

• a topic in conversation
• a subject of study
• an issue under discussion

So in this sentence, הנושא is best understood as the subject or the topic, depending on the broader context.

היטב means well.

So it describes how well she knows the subject.

It is a correct and fairly common word, though in everyday spoken Hebrew many people also use טוב in some contexts. Still, היטב is very natural here and sounds a bit more polished or formal than some everyday alternatives.

Putting היטב at the end is a very natural Hebrew word order.

The basic structure here is:

• היא — subject
• מכירה — verb
• את הנושא — object
• היטב — adverb

So the sentence follows a common pattern: subject + verb + object + adverb.

Hebrew word order is somewhat flexible, and you may also hear:

• היא מכירה היטב את הנושא

That is also correct. The version with היטב at the end is completely natural.

You would change both the subject pronoun and the verb form:

• הוא מכיר את הנושא היטב. — He knows the subject well.

Here:

• הוא = he
• מכיר = masculine singular present form

So the verb must agree with the gender of the subject.

A simple transliteration is:

hi makira et ha-nose heitev

A rough pronunciation guide:

• היא — hee
• מכירה — ma-kee-RA
• את — et
• הנושא — ha-no-SE
• היטב — hei-TEV

So the full sentence sounds roughly like:

hee ma-kee-RA et ha-no-SE hei-TEV

In standard Hebrew, no. Since הנושא is a definite direct object, את is required.

So:

• היא מכירה את הנושא היטב — correct
• היא מכירה הנושא היטב — not standard

This is one of the most important uses of את for learners to remember.

Yes. Hebrew does not normally use a separate present-tense form of to be in sentences like this.

So Hebrew simply says:

• היא מכירה את הנושא היטב

There is no word corresponding to English is here. The present-time meaning is understood from the verb form מכירה.
