אל תתעלמי מהמחמאה שלה; היא אמרה אותה בכנות.

Because תתעלמי is the 2nd person feminine singular future form of להתעלם (to ignore / to disregard).

With אל + future, Hebrew makes a negative command, so:

• אל תתעלמי = don’t ignore (said to one woman)
• אל תתעלם = to one man
• אל תתעלמו = to more than one person

So the form תתעלמי tells you the speaker is talking to a female singular listener.

In Hebrew, negative commands are normally made with אל plus a future-tense form.

So:

• תתעלמי by itself is formally a future form: you will ignore
• אל תתעלמי means don’t ignore

This is the standard way to say don’t do X in normal Hebrew.

Compare:

• התעלמי! = Ignore! (positive command, feminine singular)
• אל תתעלמי! = Don’t ignore!

Because the verb להתעלם requires the preposition מ־ (from).

So in Hebrew, you do not literally say ignore the compliment with a direct object. Instead, you say something more like:

• להתעלם מ־... = to ignore / disregard ...

That gives:

• מהמחמאה = from the compliment

Since מ־ is attached to המחמאה, the form becomes מהמחמאה.

So the structure is:

• אל תתעלמי מהמחמאה שלה
  literally: Don’t ignore from her compliment naturally: Don’t ignore her compliment

מחמאה means compliment.

It is a feminine singular noun, which matters later in the sentence because the pronoun referring back to it is also feminine:

• מחמאה = compliment
• אותה = it (feminine singular object)

So אותה refers back to מחמאה.

שלה means hers / her.

Hebrew often expresses possession with:

• noun + possessive word

So:

• המחמאה שלה = her compliment
• literally: the compliment of hers

Some similar forms are:

• שלי = my/mine
• שלך = your/yours
• שלו = his
• שלה = her/hers
• שלהם = their/theirs

So המחמאה שלה is a very normal way to say her compliment.

אותה is the direct object pronoun meaning her or it in the feminine singular.

Here it means it, referring back to המחמאה (the compliment), which is feminine.

So:

• היא אמרה אותה = she said it
• אותה = it (feminine singular)

Hebrew often uses an explicit object pronoun where English might also use one. In this sentence, it makes the reference clear: she said the compliment sincerely.

Yes, it could, but the meaning would be a little less explicit.

• היא אמרה אותה בכנות = She said it sincerely
• היא אמרה בכנות = She spoke sincerely / She said it sincerely depending on context

Including אותה clearly points back to the compliment. Without it, the sentence still works in context, but it is slightly less precise.

Because היא means she, and אמרה is the past tense, 3rd person feminine singular form of לומר (to say).

So:

• הוא אמר = he said
• היא אמרה = she said

This matches the subject היא.

בכנות means sincerely or with sincerity.

It is built from:

• כנות = sincerity / honesty / genuineness
• ב־ = in / with

So:

• בכנות = with sincerity, sincerely

This is a very common Hebrew pattern: ב־ + noun can function like an adverb in English.

For example:

• ברצינות = seriously
• בשקט = quietly
• בכנות = sincerely

Yes, approximately. אותה is pronounced roughly o-ta.

A few pronunciation notes for the whole sentence:

• אל = al
• תתעלמי = roughly tit-al-mi or teet-al-mi
• מהמחמאה = roughly me-ha-ma-kha-a or ma-ha-makha-a depending on speech flow
• שלה = she-la
• היא אמרה אותה בכנות = hi am-ra o-ta be-khe-nut

The כ in בכנות is the throaty Hebrew kh sound.

Yes. Hebrew punctuation is generally used much like English punctuation.

The semicolon here separates two closely related clauses:

• אל תתעלמי מהמחמאה שלה
• היא אמרה אותה בכנות

You could also write them as two separate sentences, or sometimes with a comma depending on style. The semicolon simply shows a stronger break than a comma, while keeping the ideas connected.

Yes, normally להתעלם takes מ־.

Examples:

• התעלמתי ממנו = I ignored him
• אל תתעלם מהבעיה = Don’t ignore the problem
• היא מתעלמת מהמחמאה = She is ignoring the compliment

This is something English speakers often need to memorize, because English ignore takes a direct object, but Hebrew להתעלם takes a prepositional complement with מ־.

The dictionary form is להתעלם.

That is the infinitive, meaning to ignore or to disregard.

From that verb, you get forms like:

• אני מתעלמת = I ignore / I’m ignoring (feminine speaker)
• הוא התעלם = he ignored
• היא התעלמה = she ignored
• תתעלמי = you will ignore / don’t ignore (with אל, feminine singular)

So when learning vocabulary, you would usually store this as:

• להתעלם מ־ = to ignore

Yes, depending on context, בכנות can suggest sincerely, honestly, or genuinely.

In this sentence, sincerely is the most natural choice because the topic is a compliment:

• היא אמרה אותה בכנות = She said it sincerely

The idea is that the compliment was genuine, not fake or merely polite.
