התוכן של ההודעה לא ברור לי, כי חצי מהמשפט נעלם.

Yes. התוכן means the content, and של ההודעה means of the message.

So:

• התוכן = the content
• של = of
• ההודעה = the message

Together: התוכן של ההודעה = the content of the message

This is a very common Hebrew way to express possession or an of relationship.

Hebrew has two common ways to say something like the content of the message:

1. התוכן של ההודעה
2. תוכן ההודעה

Both are possible.

The version with של is often felt to be a bit more everyday and explicit, especially in spoken Hebrew.
The construct form תוכן ההודעה is also completely natural and may sound slightly more formal or compact.

So the sentence could also have been:

• תוכן ההודעה לא ברור לי...

But התוכן של ההודעה is perfectly normal.

Because it means the message, not just a message.

• הודעה = a message / message
• ההודעה = the message

In התוכן של ההודעה, both nouns are definite:

• התוכן = the content
• ההודעה = the message

So the phrase is specifically talking about a particular message.

Literally, it means not clear to me.

Breakdown:

• לא = not
• ברור = clear
• לי = to me

So לא ברור לי is literally it is not clear to me.

In natural English, that often becomes:

• I don’t understand
• It isn’t clear to me

Hebrew often uses this kind of structure where English would use a verb like understand.

Because Hebrew often attaches prepositions to pronoun endings.

Here the basic preposition is ל־ = to / for.

So:

• לי = to me
• לך = to you (masculine singular)
• לך = to you (feminine singular; same spelling, different pronunciation in fully pointed text)
• לו = to him
• לה = to her
• לנו = to us
• להם / להן = to them

So ברור לי is literally clear to me.

Because it agrees with התוכן, which is masculine singular.

In Hebrew, adjectives usually agree with the noun they describe in gender and number.

• תוכן is masculine singular
• therefore the adjective is ברור = masculine singular

If the noun were feminine singular, you would expect ברורה.

For example:

• ההודעה ברורה לי = The message is clear to me

Here הודעה is feminine singular, so the adjective becomes ברורה.

Yes. כי here means because.

So:

• כי חצי מהמשפט נעלם = because half of the sentence disappeared

This is a very common word for introducing a reason.

Depending on context, כי can also mean that in some kinds of Hebrew, but in this sentence it clearly means because.

חצי מהמשפט means half of the sentence.

Breakdown:

• חצי = half
• מ־ = from / of
• המשפט = the sentence

In this pattern, Hebrew often uses חצי מ־... to mean half of ....

So:

• חצי מהמשפט = half of the sentence

You may also sometimes see חצי המשפט, especially in more compact styles, but חצי מהמשפט is extremely common and natural.

The מ־ here is not really translated as from in English; in this structure it gives the meaning of.

Here נעלם means disappeared.

So:

• חצי מהמשפט נעלם = half of the sentence disappeared

The verb comes from the root ע-ל-ם in the נפעל pattern, and it often has the meaning of something vanishing, going missing, or disappearing.

Depending on context, נעלם can sometimes also feel like is missing or has disappeared, because Hebrew tense/aspect does not always match English one-to-one.

In this sentence, the natural translation is disappeared or is missing.

This is a great question, because in unpointed Hebrew the form נעלם can look the same for more than one grammatical use.

In context here, it is understood as past or as a completed event:

• half of the sentence disappeared

But depending on context, the same written form can sometimes be interpreted differently.

That is normal in Hebrew: context often tells you how to understand the form.

In this sentence, the most natural reading is that part of the sentence vanished from the message, so disappeared is the best interpretation.

Because משפט can mean different things depending on context, including:

• sentence (in grammar/language)
• trial
• judgment
• legal case

Here the context is a message whose content is unclear because half of it is missing. So משפט clearly means sentence in the grammatical sense.

This is very common in Hebrew: one word may have several meanings, and context tells you which one is intended.

Hebrew often prefers a structure like X is not clear to me instead of I do not understand X.

So instead of:

• I don’t understand the content of the message

Hebrew says:

• התוכן של ההודעה לא ברור לי
• literally: The content of the message is not clear to me

This sounds natural in Hebrew. It is not strange or overly formal.

Hebrew and English often express the same idea with different sentence structures, so it is good to get used to these common Hebrew patterns rather than translating word-for-word from English.

Yes, often you could, but the tone changes slightly.

For example:

• אני לא מבין את התוכן של ההודעה = I don’t understand the content of the message

This is also grammatical and natural.

But לא ברור לי sounds a bit more like:

• it’s unclear to me
• I’m not sure what it means
• it isn’t clear

So the original sentence is slightly less direct and focuses on the message being unclear, rather than on the speaker’s act of understanding.

The comma separates the main clause from the reason clause:

• התוכן של ההודעה לא ברור לי
• כי חצי מהמשפט נעלם

So it works like:

• The content of the message isn’t clear to me, because half of the sentence disappeared.

In modern Hebrew punctuation, a comma before כי is common when it introduces a full explanatory clause like this. You may sometimes see variation in informal writing, but the comma here is very normal.

A common pronunciation would be:

ha-to-khen shel ha-ho-da-a lo ba-rur li, ki khe-tsi me-ha-mish-pat ne-e-lam

A smoother transliteration:

ha-tokhen shel ha-hoda'ah lo barur li, ki khetzi meha-mishpat ne'elam

Word by word:

• התוכן — ha-tokhen
• של — shel
• ההודעה — ha-hoda'ah
• לא — lo
• ברור — barur
• לי — li
• כי — ki
• חצי — khetzi
• מהמשפט — meha-mishpat
• נעלם — ne'elam

Different speakers may pronounce some vowels a little differently, but this will guide you well.
