אחרי העדכון המערכת חזרה לעבוד, והדוח נשלח לכולנו באימייל.

Because המערכת is a feminine singular noun, and the past-tense verb agrees with it.

• חזר = he returned / it returned (masculine)
• חזרה = she returned / it returned (feminine)

So המערכת חזרה is the correct agreement for the system returned / resumed.

Literally, חזרה לעבוד means returned to work. In natural English, for a system, that usually becomes started working again or resumed working.

Hebrew often uses לחזור + infinitive to express doing something again:

• חזר לעבוד = resumed working
• חזר ללמוד = went back to studying
• חזרה לישון = went back to sleep

So this is a very normal Hebrew structure.

לעבוד is the infinitive, meaning to work. The ל־ at the beginning is part of the infinitive form here.

After verbs like חזר, Hebrew commonly uses an infinitive:

• חזר לעבוד = resumed working
• התחיל לעבוד = started working
• הפסיק לעבוד = stopped working

So חזרה לעבוד is structurally very standard.

אחרי העדכון is a time expression: after the update. Hebrew often places time expressions at the beginning of a sentence, just as English can.

So this word order is natural:

• אחרי העדכון המערכת חזרה לעבוד

You could also say:

• המערכת חזרה לעבוד אחרי העדכון

Both are grammatical. Starting with אחרי העדכון gives the time context first.

The ה־ is the definite article, meaning the. So העדכון means the update.

In this sentence, the speaker is referring to a specific update, not just any update. That is why Hebrew uses the definite form.

• עדכון = an update / update
• העדכון = the update

Because נשלח is the passive form here: was sent.

• שלח = sent (active)
• נשלח = was sent (passive)

So:

• מישהו שלח את הדוח = someone sent the report
• הדוח נשלח = the report was sent

This sentence uses the passive because the focus is on the report, not on who sent it.

Hebrew does not need a separate word for was here. The single verb נשלח already includes that meaning.

So:

• הדוח נשלח = the report was sent

This is very common in Hebrew. English often uses was + past participle, but Hebrew can express the whole passive idea in one verb form.

Because הדוח is the subject of the passive clause, not a direct object.

Hebrew uses את before a definite direct object in an active sentence:

• שלחו את הדוח = they sent the report

But in the passive version:

• הדוח נשלח = the report was sent

Here הדוח is not an object anymore, so את disappears.

Because it agrees with הדוח, which is masculine singular.

In Hebrew, verbs in the past tense agree with the subject in gender and number.

• הדוח נשלח = the report was sent
• ההודעה נשלחה = the message was sent
• הדוחות נשלחו = the reports were sent

So the form נשלח matches הדוח.

לכולנו means to all of us. It is made of:

• ל־ = to
• כול = all
• ־נו = us / our

Together: לכולנו = to all of us

This is a common Hebrew pattern:

• לכולכם = to all of you
• לכולן = to all of them (feminine)
• לכולנו = to all of us

The prefix ב־ can mean in, at, or by/via, depending on context. With methods of communication, it often means by or via.

So:

• באימייל = by email / via email
• בטלפון = by phone
• בהודעה = by message / in a message

In this sentence, באימייל tells you the method used to send the report.

That ו־ is simply the word and attached to the next word.

So:

• והדוח = and the report

This is how Hebrew normally writes and: it is prefixed directly to the following word rather than written separately.
