המזגן במשרד מקולקל, ולכן היום חם שם מאוד.

In present-tense Hebrew, the verb to be is usually omitted.

So:

• המזגן במשרד מקולקל = The air conditioner in the office is broken

Literally, Hebrew says something like:

• the-air-conditioner in-the-office broken

This is completely normal in modern Hebrew.
If you wanted past or future, then Hebrew would use forms of to be:

• המזגן היה מקולקל = The air conditioner was broken
• המזגן יהיה מקולקל = The air conditioner will be broken

מזגן means air conditioner.
The prefix ה is the Hebrew definite article, meaning the.

So:

• מזגן = an air conditioner / air conditioner
• המזגן = the air conditioner

The ה is attached directly to the noun, unlike English, where the is a separate word.

במשרד means in the office.

It is made of:

• ב־ = in
• משרד = office

So:

• משרד = office
• במשרד = in an office / in the office

Because Hebrew often attaches prepositions directly to the following word, ב is not written separately.

Also, when ב־ is attached to a noun with the, the article is absorbed:

• ב + המשרד becomes במשרד

So במשרד here means in the office, not just in office.

מקולקל means broken, damaged, or out of order.
In this sentence, it functions like an adjective describing המזגן.

So:

• המזגן ... מקולקל = the air conditioner ... is broken

It is not a main action verb here. It describes a state.

A useful thing to notice is agreement:

• מזגן is masculine singular
• מקולקל is also masculine singular

Other forms would be:

• מקולקלת = feminine singular
• מקולקלים = masculine plural
• מקולקלות = feminine plural

Yes, מזגן is masculine.

You can tell here because the describing word is מקולקל, which is masculine singular.
If מזגן were feminine, you would expect מקולקלת.

So the sentence gives you agreement clues:

• המזגן ... מקולקל
  masculine noun + masculine adjective

In Hebrew, grammatical gender matters because adjectives usually match the noun they describe.

ולכן means and therefore, so, or therefore.

It is made of:

• ו־ = and
• לכן = therefore / so

So the sentence structure is:

• The air conditioner in the office is broken, therefore today it is very hot there.

In natural English, you might translate it more smoothly as:

• The air conditioner in the office is broken, so it’s very hot there today.

Hebrew often uses ו־ very freely to connect ideas.

That is a very common learner question.

Yes, היום literally looks like:

• ה = the
• יום = day

But in actual usage, היום is also the normal word for today.

So depending on context, היום can mean:

• today
• the day

In this sentence, it clearly means today because it is functioning as a time expression:

• ולכן היום חם שם מאוד = and therefore today it is very hot there

When Hebrew talks about the weather, it often uses masculine singular forms like חם (hot) and קר (cold), even when there is no obvious masculine noun right next to them.

So:

• היום חם = today it is hot
• היום קר = today it is cold

This is similar to English it is hot, where it does not refer to a specific thing.

So here חם is the normal weather expression, not an adjective agreeing with משרד or היום.

Here, שם means there.

Hebrew שם can mean:

• there
• name

The meaning depends on context.

In this sentence:

• חם שם מאוד = it is very hot there

So שם is a place word, meaning there.

Hebrew word order is often flexible, but חם שם מאוד is very natural.

It breaks down as:

• חם = hot
• שם = there
• מאוד = very

So literally:

• hot there very

In smoother English:

• it is very hot there

Hebrew often puts מאוד after the adjective it modifies:

• חם מאוד = very hot
• גדול מאוד = very big
• יפה מאוד = very beautiful

Here שם is inserted before מאוד, but the sentence still sounds natural.
You could also hear:

• שם חם מאוד

That would also mean it’s very hot there, with slightly different emphasis.

מאוד means very, and in Hebrew it usually comes after the adjective or adverb it modifies.

Examples:

• חם מאוד = very hot
• טוב מאוד = very good
• לאט מאוד = very slowly

In this sentence, מאוד comes at the end of the clause:

• חם שם מאוד

That is perfectly normal Hebrew. The main idea is that מאוד usually follows, not precedes, the word it strengthens.

Not very naturally.

A rough word-for-word version would be:

• The-air-conditioner in-the-office broken, and-therefore today hot there very.

That helps show the structure, but it is not natural English.

A good natural English translation would be:

• The air conditioner in the office is broken, so it’s very hot there today.

This is a good reminder that Hebrew and English often organize sentences differently, even when the meaning is straightforward.

A simple pronunciation guide is:

• ha-maz-GAN ba-mis-RAD me-kul-KAL, ve-la-KHEN ha-YOM kham SHAM me-OD

A few notes:

• kh represents the throaty Hebrew sound in words like חם
• stress often falls near the end of the word:
  • מזגן = mazGAN
  • משרד = misRAD
  • מקולקל = mekulKAL
  • לכן = laKHEN
  • מאוד = meOD

You do not need perfect pronunciation immediately, but it helps to notice where the stress falls.

Yes. Hebrew allows some variation in word order and phrasing.

For example:

• המזגן במשרד מקולקל, אז היום חם שם מאוד.
  • אז = so

Or:

• המזגן במשרד מקולקל, ולכן שם חם מאוד היום.

These mean basically the same thing, though the emphasis changes slightly.

The original sentence is natural and correct, and it is a good model to learn from.
