היא מדברת בנימוס, אפילו כשהיא כועסת.

Because the subject is היא (she). In Hebrew, present-tense verbs agree with the subject in gender and number.

The base verb is לדבר (to speak). Its present forms are:

• מדבר — masculine singular
• מדברת — feminine singular
• מדברים — masculine/mixed plural
• מדברות — feminine plural

So with היא, מדברת is the correct form.

It can mean either one, depending on context.

Hebrew present tense often covers both:

• she speaks
• she is speaking

In this sentence, the most natural meaning is a general/habitual one: She speaks politely, even when she’s angry.

If the context were about something happening right now, it could also be understood as she is speaking politely.

נימוס means politeness, good manners, or courtesy.

The prefix ב־ usually means in, with, or by. So בנימוס literally means something like:

• with politeness
• in a polite manner

In natural English, that becomes politely.

This is very common in Hebrew: instead of using a separate adverb form, Hebrew often uses ב + noun.

Because מנומסת is an adjective, while בנימוס works as an adverbial expression.

• היא מנומסת = She is polite
• היא מדברת בנימוס = She speaks politely

In other words:

• מנומסת describes the person
• בנימוס describes the way she speaks

So after a verb like מדברת, בנימוס is the natural choice.

אפילו means even.

It adds emphasis and shows that the following situation is a bit surprising or noteworthy. So:

• אפילו כשהיא כועסת = even when she is angry

The idea is: she speaks politely in general, and this is true even in a situation when you might not expect it.

It is written as one word, because כש־ is a prefix.

• כש־ = when
• היא = she

So:

• כשהיא = when she

The כש־ part is a shorter, very common form of כאשר (when). Hebrew often attaches small words like this directly to the next word.

Because that part is its own clause: when she is angry.

Hebrew usually needs the subject stated there, so:

• כשהיא כועסת = when she is angry

English can sometimes shorten this kind of phrase to even when angry, but Hebrew most naturally keeps the subject here.

So the second היא is not redundant; it belongs to the clause introduced by כש־.

כועסת is the feminine singular present form of לכעוס, which means to be angry or to get angry.

Because the subject is היא, the feminine form is used:

• כועס — masculine singular
• כועסת — feminine singular

In English, we usually say she is angry. In Hebrew, היא כועסת is the normal way to express that idea.

Sometimes, yes.

Hebrew often drops subject pronouns when the subject is already clear from context. So you might hear:

• מדברת בנימוס, אפילו כשהיא כועסת

However, in the present tense, Hebrew often keeps pronouns because present-tense forms do not clearly show person the way past and future forms do.
So היא מדברת is very normal and clear.

The second היא in כשהיא כועסת is more likely to stay.

You change the verb and adjective/participle forms to match the subject.

For a man:

• הוא מדבר בנימוס, אפילו כשהוא כועס.
• He speaks politely, even when he’s angry.

For women:

• הן מדברות בנימוס, אפילו כשהן כועסות.
• They speak politely, even when they’re angry.

For a mixed group or a group of men:

• הם מדברים בנימוס, אפילו כשהם כועסים.
• They speak politely, even when they’re angry.

A simple pronunciation guide is:

hi medaberet be-nimus, afilu kshe-hi ko-eset

Word by word:

• היא — hi
• מדברת — medaberet
• בנימוס — be-nimus
• אפילו — afilu
• כשהיא — kshe-hi
• כועסת — ko-eset

A very natural flow would be:

hi medaberet be-nimus, afilu kshe-hi ko-eset
