הם יבדקו את מונה החשמל כמו שחברת החשמל הסבירה.

יבדקו is the 3rd person masculine plural future form of לבדוק (to check / inspect).

So:

• הוא יבדוק = he will check
• הם יבדקו = they will check

In this sentence, it matches הם.

Because Hebrew often allows the subject pronoun to be omitted, but it can still be added for:

• emphasis
• contrast
• clarity

So both are possible:

• הם יבדקו את מונה החשמל...
• יבדקו את מונה החשמל...

With הם, the sentence puts a little more focus on they.

את marks a definite direct object.

Here, מונה החשמל is the thing being checked, so it is the direct object. It is also definite, so Hebrew uses את.

This את does not mean with here. It is just the direct-object marker.

A useful rule:

• definite direct object → usually את
• indefinite direct object → usually no את

Because this is a construct chain (called סמיכות).

In a construct chain:

• the first noun connects directly to the second noun
• the first noun usually does not take ה־
• definiteness is shown on the second noun

So:

• מונה החשמל = the electricity meter / the electric meter

That is why המונה החשמל is not correct here.

Hebrew often prefers the construct chain over a של phrase when two nouns naturally belong together.

So מונה החשמל is the more natural, compact way to say it here.

A של phrase is possible in many situations, but it often sounds:

• heavier
• less fixed
• less idiomatic in expressions like this

No. Here מונה is a noun, meaning meter or counter.

That can confuse learners because מונה can also appear as a verb form in other contexts. But in this sentence, it is clearly a noun because:

• it comes after את
• it begins a noun phrase: מונה החשמל

So here it means meter, not counts.

כמו ש־ means something like:

• as
• the way that
• just as

So כמו שחברת החשמל הסבירה means in the way that the electric company explained.

In this sentence, כמו is not just a loose like. It introduces a clause meaning as / the way that.

Because ש־ is a prefix meaning that or introducing a subordinate clause.

After כמו, Hebrew commonly uses:

• כמו ש־...

Since ש־ is a prefix, it attaches to the next word:

• כמו שחברת החשמל הסבירה

So this is basically:

• כמו
  • ש־
    • חברת החשמל הסבירה

Because חברת is the construct form of חברה.

So this is another construct chain:

• חברת החשמל

Literally, structurally, it is like company of the electricity, but in natural English it is the electric company or specifically the Electric Company.

This phrase is also a well-known fixed name in Israeli Hebrew.

Because חברת החשמל is grammatically feminine singular.

The head noun is חברה (company), which is feminine. In the construct form it becomes חברת, but it is still feminine singular. So the verb agrees with it:

• חברת החשמל הסבירה
• not חברת החשמל הסביר

So הסבירה is the correct past-tense form of להסביר for a feminine singular subject.

Yes. In a construct chain, the whole phrase becomes definite if the second noun is definite.

So:

• חברת החשמל is definite because of החשמל
• מונה החשמל is also definite because of החשמל

This is why both phrases can be definite even though the first word in each one has no ה־.

Yes. Hebrew word order is flexible.

For example, you could also say:

• יבדקו את מונה החשמל כמו שחברת החשמל הסבירה

That is still natural Hebrew.

The version with הם at the beginning is also natural, but it gives a bit more attention to the subject they.
