אחד היתרונות של העבודה הזאת הוא שאפשר לעבוד מהבית.

Because אחד היתרונות means one of the advantages.

Hebrew often uses this pattern:

• אחד ה... = one of the...
• אחת ה... = one of the... with a feminine noun

Here:

• אחד = one
• היתרונות = the advantages

So the idea is not one advantage in general, but one of the advantages belonging to this job.

Because יתרון is a masculine noun.

• singular: יתרון = advantage
• plural: יתרונות = advantages

Even though the plural ending ־ות often looks feminine, not every noun ending in ־ות is feminine. יתרון is masculine, so you say:

• אחד היתרונות = one of the advantages

Not אחת היתרונות.

היתרונות is the plural definite form of יתרון.

Breakdown:

• יתרון = advantage
• יתרונות = advantages
• היתרונות = the advantages

So in the sentence, אחד היתרונות literally means one [of] the advantages.

של is the common Hebrew word for of or belonging to.

So:

• היתרונות של העבודה הזאת = the advantages of this job / this work

This is a very common possession/association structure in modern Hebrew:

• הספר של דני = Danny’s book
• הצבע של המכונית = the color of the car
• היתרונות של העבודה הזאת = the advantages of this job

In Hebrew, demonstratives like this usually come after the noun:

• העבודה הזאת = this job / this work
• הספר הזה = this book
• הילדה הזאת = this girl

Also, the demonstrative has to agree with the noun:

• עבודה is feminine singular
• so you use זאת

That is why you get העבודה הזאת.

In Hebrew, when you say this/that + noun, the noun is normally definite, so it takes ה־.

That is why Hebrew says:

• העבודה הזאת = this job
• הבית הזה = this house
• המכונית הזאת = this car

So using both ה־ and זאת/זה is completely normal.

Here הוא acts like a link in a present-tense sentence, similar to is in English.

Hebrew often has no separate word for is in simple present-tense sentences, but when the predicate is longer or more complex—especially before a clause—Hebrew often uses הוא (or היא, הם, etc.):

• היתרון הוא שאפשר... = the advantage is that one can...
• הבעיה היא ש... = the problem is that...
• השאלה היא אם... = the question is whether...

So in this sentence, הוא helps connect:

• אחד היתרונות של העבודה הזאת to
• שאפשר לעבוד מהבית

שאפשר is made of:

• ש־ = that
• אפשר = it is possible / one can / you can

So שאפשר לעבוד מהבית means something like:

• that it’s possible to work from home
• that you can work from home
• that one can work from home

A useful thing to know is that אפשר is often impersonal. It does not directly say who can do it; it just says that it is possible.

Examples:

• אפשר להיכנס? = Is it possible to come in? / May I come in?
• אפשר לשבת כאן = It’s possible to sit here / You can sit here

Because after אפשר, Hebrew usually uses an infinitive.

So:

• אפשר לעבוד = it’s possible to work / you can work

This is a very common pattern:

• אפשר לראות = you can see
• אפשר לאכול = you can eat
• אפשר להתחיל = you can start

Using the infinitive after אפשר is the normal way to express this idea.

In Hebrew, לעבוד מהבית is the normal expression for to work from home.

Breakdown:

• מ־ = from
• הבית = the house / the home
• מהבית = from the house/home

In this context, בית often means home, not just a physical house. So לעבוד מהבית is the standard way to say work from home.

Also notice the contraction:

• מ + הבית becomes מהבית

Yes, but it means something slightly different.

• לעבוד מהבית = to work from home
  This emphasizes remote work, as opposed to going to an office.

• לעבוד בבית = to work at home / in the house
  This can simply describe where the work happens physically.

In many situations they are close, but מהבית is the more idiomatic choice for working from home in the modern remote-work sense.

This is a very common Hebrew structure:

• X הוא ש... = X is that...

So:

• אחד היתרונות של העבודה הזאת הוא שאפשר לעבוד מהבית
• literally: One of the advantages of this job is that it is possible to work from home

Hebrew often introduces explanations like this with ש־ after הוא / היא:

• הבעיה היא שאין זמן = the problem is that there is no time
• הסיבה היא שהוא עייף = the reason is that he is tired

So the structure is very natural.

A natural chunking would be:

אחד היתרונות | של העבודה הזאת | הוא | שאפשר לעבוד מהבית

This helps you hear the sentence in pieces:

1. אחד היתרונות = one of the advantages
2. של העבודה הזאת = of this job
3. הוא = is
4. שאפשר לעבוד מהבית = that you can work from home

Thinking in chunks like this is often easier than trying to process the whole sentence word by word.
