הרעש מפחיד את החתול.

The subject is הרעש and the object is החתול.

A very important clue is את. In Hebrew, את marks a definite direct object, so את החתול tells you that the cat is receiving the action.

So the structure is:

• הרעש = the subject
• מפחיד = the verb
• את החתול = the direct object

That is why the sentence means that the noise is frightening the cat, not the other way around.

In this sentence, את does not really have a direct English translation. It is a grammatical marker.

Hebrew uses את before a definite direct object. Since החתול means the cat and is definite, Hebrew normally requires את before it:

• מפחיד את החתול

If the object were indefinite, את would usually disappear:

• הרעש מפחיד חתול = the noise frightens a cat

So את is not the word for with here. It is the object marker.

The prefix ה־ is the Hebrew definite article, meaning the.

So:

• רעש = noise
• הרעש = the noise
• חתול = cat
• החתול = the cat

Since the sentence uses the noise and the cat, both nouns take ה־.

מפחיד is a present-tense verb form.

It comes from the root פ־ח־ד, which is connected with fear. In this pattern, the verb means to frighten or to scare.

Here, מפחיד is the masculine singular present form, and it agrees with the subject הרעש, which is grammatically masculine singular.

Compare:

• הילד מפחיד את הכלב = the boy is frightening the dog
• המוזיקה מפחידה את הילד = the music is frightening the boy

Notice that with a feminine singular subject, the verb changes to מפחידה.

In Hebrew, present-tense sentences usually do not use a separate word for is / am / are the way English does.

So Hebrew often says:

• הוא עייף = he is tired
• החתול גדול = the cat is big

In your sentence, though, מפחיד is already a verb meaning frightens / is frightening, so there is no need for a separate is anyway.

This is normal Hebrew structure.

It can correspond to either one in English, depending on context.

Hebrew present tense often covers meanings that English may express in more than one way:

• frightens
• is frightening
• sometimes even does frighten, depending on emphasis

So הרעש מפחיד את החתול can match the English idea the noise frightens the cat or the noise is frightening the cat.

In everyday learning, it is usually easiest to think of מפחיד here as frightens.

Yes, Hebrew word order is somewhat flexible, but the most neutral order here is:

• הרעש מפחיד את החתול

Because את marks the object, Hebrew can sometimes move things around without causing confusion. But for learners, the standard order subject + verb + object is the safest and most natural.

For example, a different order might be used for emphasis, but it is better to learn the basic pattern first.

Not in this sentence, if you want standard Hebrew.

Because החתול is a definite direct object, את should be there:

• correct: הרעש מפחיד את החתול
• not standard: הרעש מפחיד החתול

Hebrew normally requires את before definite direct objects.

A simple pronunciation guide is:

ha-ra'ash maf-KHID et ha-kha-TUL

A few notes:

• ה at the beginning is usually ha-
• רעש has a kind of break between the two vowels: ra'ash
• ח is a throaty sound, like the ch in some pronunciations of Bach
• stress in מפחיד is on the last syllable: maf-KHID
• stress in החתול is also on the last syllable: ha-kha-TUL

רעש is grammatically masculine.

That matters because Hebrew verbs in the present tense agree with the subject in gender and number.

Since הרעש is masculine singular, the verb is also masculine singular:

• מפחיד

If the subject were feminine singular, the verb would change:

• המכונה מפחידה את החתול = the machine frightens the cat

So the verb form helps show agreement with the subject.

Yes. מפחיד comes from the root פ־ח־ד, which is related to fear.

Some related words are:

• פחד = fear
• לפחד = to be afraid
• להפחיד = to frighten / to scare
• מפחיד = frightening / frightens

This is a useful Hebrew pattern: the same root often appears in several related words, but in different verb patterns and noun forms. So learning the root can help you recognize a whole family of related words.
