המערכת במשרד לא עבדה בבוקר, ולכן שום קובץ לא נשלח.

מערכת is a feminine singular noun in Hebrew. Because Hebrew verbs agree with the subject in gender and number, the verb in the first clause is עבדה, the feminine singular past form.

So:

• המערכת עבדה = the system worked
• if the subject were masculine, you would expect עבד

This kind of agreement is very important in Hebrew, especially in the past tense.

Hebrew usually does not need an explicit subject pronoun when the subject is already stated.

In English, you might say:

• the system ... it didn’t work

But in Hebrew, once you have המערכת, there is no need to add היא unless you want special emphasis or contrast.

So המערכת לא עבדה is the normal way to say it.

The ב־ preposition means in / at, and Hebrew normally attaches it directly to the following word, so it becomes one written unit:

• ב־ + משרד → במשרד

In unpointed Hebrew, במשרד can be a little ambiguous:

• be-misrad = in an office / in the office
• ba-misrad = in the office

Because modern Hebrew usually omits vowel marks, the spelling stays the same. You understand the exact meaning from context.

For the same reason: Hebrew attaches short prepositions like ב־ to the next word.

Here it is:

• ב־ + הבוקר → בבוקר

This is a very common contraction. The phrase בבוקר means in the morning.

Hebrew often uses this pattern in time expressions, for example:

• בבוקר = in the morning
• בערב = in the evening
• בלילה = at night

ולכן is made of:

• ו־ = and
• לכן = therefore / so

Together, ולכן means and therefore, therefore, or so.

It sounds a bit more logical or formal than a simple spoken אז. It is very natural in writing and in careful speech when one clause is clearly the result of the first.

שום with a singular noun and a negative verb means no, not any, or not a single.

So:

• שום קובץ לא נשלח

means something like:

• no file was sent
• not a single file was sent

This is a very normal Hebrew structure. Even though English learners sometimes worry about שום together with לא, this is not a problem in Hebrew. That combination is exactly what you expect.

After שום, Hebrew normally uses a singular noun:

• שום קובץ
• שום מכתב
• שום בעיה

Even though English may sometimes prefer a plural idea like no files, Hebrew commonly uses the singular after שום. The meaning is still collective: not even one file.

Because נשלח here is the form meaning was sent.

Compare:

• שלח = he sent
• נשלח = was sent / got sent

So the sentence is using a passive-like form. The focus is on what happened to the file, not on who did the sending.

This is very common in Hebrew when the sender is unknown, irrelevant, or simply not mentioned.

The verb agrees with קובץ, which is a masculine singular noun.

So:

• קובץ נשלח = a file was sent

If the noun were feminine singular, the verb would change. If it were plural, the verb would also change. For example:

• קבצים לא נשלחו = files were not sent

So the form נשלח matches קובץ exactly.

The given word order is very natural and neutral:

• המערכת במשרד לא עבדה בבוקר, ולכן שום קובץ לא נשלח.

But Hebrew word order is somewhat flexible, especially with time expressions like בבוקר.

For example, you could also say:

• בבוקר המערכת במשרד לא עבדה...

That would put more emphasis on in the morning.

So the original sentence is not the only possible order, but it is a smooth and standard one.
