כשאני כותבת אימייל חשוב, אני נעזרת במילון כדי לבדוק כל מילה.

Because the speaker is female.

In Hebrew present-tense verbs agree with the subject in gender and number. Here:

• כותבת = feminine singular writing
• נעזרת = feminine singular using / relying on

If the speaker were male, the sentence would be:

כשאני כותב אימייל חשוב, אני נעזר במילון כדי לבדוק כל מילה.

כשאני means when I.

It is made of:

• כש־ = when
• אני = I

So כשאני כותבת... literally means when I am writing... or when I write...

In this sentence, it introduces the situation or time frame for the main action.

Because אימייל is treated as a masculine noun here.

In Hebrew, adjectives must agree with the noun they describe in gender and number:

• אימייל חשוב = an important email
• feminine example: הודעה חשובה = an important message

So חשוב matches אימייל.

Not exactly.

The verb להיעזר often means:

• to use
• to make use of
• to rely on
• to get help from

So אני נעזרת במילון is most naturally understood as:

• I use a dictionary
• I rely on a dictionary

Literally, it comes from the root related to help, but in normal usage it often means to use something as an aid.

Because the verb להיעזר normally takes ב־ before the thing you are using or relying on.

So:

• נעזרת במילון = use a dictionary / rely on a dictionary

This is just how the verb works in Hebrew.

A useful pattern is:

• להיעזר ב... = to use / rely on ...

For example:

• אני נעזר במחשב = I use a computer
• היא נעזרת בחברים = she relies on friends

In this sentence, it is best understood as using a dictionary.

With להיעזר ב־, the ב־ does not have to mean a literal in. It marks the tool or aid being used.

So אני נעזרת במילון means something like:

• I use a dictionary
• I rely on a dictionary

not just physically inside the dictionary.

כדי means in order to or so as to.

It introduces a purpose:

• אני נעזרת במילון כדי לבדוק כל מילה
• I use a dictionary in order to check every word

So the structure is:

• main action: I use a dictionary
• purpose: to check every word

Because after כדי, Hebrew normally uses the infinitive.

So:

• כדי לבדוק = in order to check

The infinitive in Hebrew often begins with ל־:

• לבדוק = to check
• לכתוב = to write
• ללמוד = to study

If you said כדי בודקת, that would be ungrammatical.

כל מילה means every word.

In Hebrew, כל is often followed by a singular noun when the meaning is every:

• כל יום = every day
• כל ילד = every child
• כל מילה = every word

If you want to say all the words, that is usually:

• כל המילים

So:

• כל מילה = every word
• כל המילים = all the words

The verbs are in the present form, but the sentence expresses a habitual action.

• כשאני כותבת... אני נעזרת...
• When I write / when I’m writing... I use...

In Hebrew, the present tense can describe:

• an action happening now
• a general habit
• something that usually happens

Here it sounds habitual or general: whenever she writes an important email, she uses a dictionary.

Yes, but the verb forms would change to masculine singular.

The masculine version is:

כשאני כותב אימייל חשוב, אני נעזר במילון כדי לבדוק כל מילה.

The parts that change are:

• כותבת → כותב
• נעזרת → נעזר

Everything else stays the same.

Yes, the word order is natural.

The sentence is organized like this:

1. כשאני כותבת אימייל חשוב = when I write an important email
2. אני נעזרת במילון = I use a dictionary
3. כדי לבדוק כל מילה = in order to check every word

Hebrew word order is somewhat flexible, but this version is very normal and clear.

For example, you could also say:

אני נעזרת במילון כשאני כותבת אימייל חשוב, כדי לבדוק כל מילה.

But the original sentence sounds smoother and more standard.

It is pronounced approximately ne-e-ZE-ret.

The א in the middle creates a slight break between syllables, so it is not one smooth syllable at the start.

A rough pronunciation guide for the whole sentence is:

kshe-ani ko-TE-vet i-MAIL kha-SHUV, ani ne-e-ZE-ret be-mi-LON kdei liv-DOK kol mi-LA

That is only an approximation, but it can help you hear the rhythm of the sentence.
