ההסבר שלך מצוין.

A common pronunciation is:

ha-hesbér shelkha metzuyán

A more detailed breakdown:

• ההסבר = ha-hesber = the explanation
• שלך = shelkha if speaking to a man, or shelakh if speaking to a woman
• מצוין = metzuyan = excellent

So the full sentence is:

• to a man: ha-hesber shelkha metzuyan
• to a woman: ha-hesber shelakh metzuyan

Note: in everyday unpointed Hebrew, שלך is spelled the same for both masculine and feminine.

The ה at the beginning is the Hebrew definite article, equivalent to the in English.

• הסבר = an explanation / explanation
• ההסבר = the explanation

So ההסבר שלך literally means the explanation of yours, which is the normal Hebrew way to say your explanation.

Because the word is made of:

• ה = the
• הסבר = explanation

When the definite article ה is added to a word that already begins with ה, the spelling becomes הה...

So:

• base word: הסבר
• with the: ההסבר

In speech, people usually pronounce it smoothly as ha-hesber.

שלך means your / yours.

In this sentence, it shows possession:

• ההסבר שלך = your explanation

Literally, Hebrew often expresses this as something like the explanation that belongs to you.

This is a very common pattern:

• הספר שלך = your book
• הבית שלך = your house
• הרעיון שלך = your idea

Yes. Hebrew marks the gender of the person being addressed.

• שלך pronounced shelkha = your when talking to a man
• שלך pronounced shelakh = your when talking to a woman

The spelling is usually the same in everyday Hebrew, so you figure it out from context or pronunciation.

So you could say:

• to a man: ההסבר שלך מצוין
• to a woman: ההסבר שלך מצוין

Same spelling, different pronunciation of שלך.

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

So:

• ההסבר שלך מצוין literally looks like your explanation excellent
• but it means your explanation is excellent

This is completely normal in Hebrew.

Compare:

• הוא עייף = he is tired
• הבית גדול = the house is big
• ההסבר שלך מצוין = your explanation is excellent

In past or future tense, Hebrew does use forms of to be:

• ההסבר שלך היה מצוין = your explanation was excellent
• ההסבר שלך יהיה מצוין = your explanation will be excellent

מצוין is an adjective here, meaning excellent. It agrees with the noun it describes.

Since הסבר is masculine singular, the adjective is also masculine singular:

• הסבר → מצוין

If the noun were feminine singular, the adjective would usually change:

• הערה שלך מצוינת = your comment/note is excellent

So in this sentence:

• ההסבר = masculine singular
• מצוין = masculine singular

That agreement is why the form is מצוין and not מצוינת.

It can do both.

In this sentence, it is an adjective:

• ההסבר שלך מצוין = your explanation is excellent

But מצוין! can also be used by itself as an exclamation:

• מצוין! = Excellent! / Great!

So learners often encounter it both as:

1. a descriptive adjective
2. a standalone response

The structure is:

[subject noun phrase] + [adjective predicate]

So:

• ההסבר שלך = subject = your explanation
• מצוין = predicate adjective = excellent

This is the normal way to say X is Y in present-tense Hebrew when Y is an adjective.

Yes, but ההסבר שלך is the most natural everyday form.

Hebrew possession is often built with:

• noun + שלך
• literally: the explanation of yours

A more formal or literary alternative with a suffix can sometimes exist in Hebrew in general, but for ordinary modern spoken Hebrew, ההסבר שלך is the standard and natural phrasing.

So if you are learning everyday Modern Hebrew, this is exactly the kind of structure you should get used to.

It is neutral and natural. It works well in speech and writing.

It sounds like a normal, polite compliment:

• ההסבר שלך מצוין. = Your explanation is excellent.

It is not slang, and it is not overly formal either. You could use it in conversation, in class, at work, or in writing.

In this specific sentence, usually only the pronunciation of שלך changes:

• to a man: shelkha
• to a woman: shelakh

The rest stays the same because הסבר is still a masculine noun, so מצוין remains masculine singular.

So:

• speaking to a man: ha-hesber shelkha metzuyan
• speaking to a woman: ha-hesber shelakh metzuyan

The spelling in ordinary Hebrew remains:

ההסבר שלך מצוין.
