אם ההסבר של המורה לא ברור, אפשר לבקש עוד דוגמה.

אם means if.

Here it introduces a condition:

• אם ההסבר של המורה לא ברור = If the teacher’s explanation is not clear
• then: אפשר לבקש עוד דוגמה = it’s possible / you can ask for another example

So the whole sentence has a very common if ... then ... structure, even though Hebrew does not need a separate word for then here.

The ה־ is the definite article, meaning the.

So:

• הסבר = an explanation / explanation
• ההסבר = the explanation
• מורה = a teacher / teacher
• המורה = the teacher

In ההסבר של המורה, both nouns are definite:

• ההסבר = the explanation
• של המורה = of the teacher

This is very natural in Hebrew when referring to a specific explanation given by a specific teacher.

English often uses a possessive instead:

• the teacher’s explanation

Hebrew can express that idea with של:

• ההסבר של המורה

של means of or shows possession, similar to ’s in English.

So:

• ההסבר של המורה = the explanation of the teacher
• more naturally in English: the teacher’s explanation

This is one of the most common ways to show possession in Modern Hebrew.

Examples:

• הספר של דנה = Dana’s book
• הבית של המשפחה = the family’s house

In the present tense, Hebrew often has no word for is / are.

So:

• ההסבר ... לא ברור literally = the explanation ... not clear
• natural English: the explanation is not clear

This is completely normal Hebrew sentence structure.

Compare:

• הוא עייף = he is tired
• היא בבית = she is at home
• זה לא קשה = it is not difficult

So ברור is an adjective, and Hebrew does not need a present-tense to be here.

Because לא normally comes right before the word or phrase being negated.

Here it negates the adjective ברור:

• ברור = clear
• לא ברור = not clear

This is the standard way to make a sentence negative in Hebrew.

אפשר literally means possible, but very often it is used impersonally to mean:

• it’s possible to...
• one can...
• you can...

So:

• אפשר לבקש עוד דוגמה literally = it is possible to ask for another example
• natural English: you can ask for another example

This is a very common Hebrew pattern:

• אפשר לשבת? = May I sit? / Is it possible to sit?
• אפשר להתחיל = We can start / It’s possible to begin

Because אפשר is often used as an impersonal expression.

Hebrew does not need to say:

• you can ask
• one can ask
• students can ask

It simply says:

• אפשר לבקש = it’s possible to ask / you can ask

The subject is understood from context. In this sentence, it means something like a student can ask or you can ask.

לבקש is the infinitive of the verb לבקש, meaning to ask for / to request.

It is made of:

• ל־ = to
• בקש = the verb stem

After אפשר, Hebrew commonly uses an infinitive:

• אפשר לבקש = it’s possible to ask
• אפשר לראות = it’s possible to see / you can see
• אפשר ללכת = it’s possible to go / you can go

So the pattern is:

• אפשר + infinitive

It can mean both, depending on context.

In this sentence, לבקש עוד דוגמה means:

• to ask for another example
• to request another example

If you just want to ask a question, Hebrew often uses לשאול:

• לשאול שאלה = to ask a question

So a useful distinction is:

• לבקש = to request / ask for something
• לשאול = to ask a question

Here the student is asking for something, so לבקש is the right verb.

עוד here means another or more.

So:

• עוד דוגמה = another example / one more example

Both are good English translations.

עוד is very common and flexible:

• עוד פעם = again / one more time
• עוד שאלה = another question
• עוד קצת = a little more

Yes. Both are correct.

• עוד דוגמה = another example / one more example
• דוגמה נוספת = an additional example

The version with עוד is very common and natural in everyday Hebrew.
נוספת sounds a bit more formal or polished, depending on context.

The comma separates the conditional clause from the main clause.

• אם ההסבר של המורה לא ברור = the if clause
• אפשר לבקש עוד דוגמה = the main clause

This is similar to English:

• If the teacher’s explanation isn’t clear, you can ask for another example.

The comma helps show the pause and the sentence structure.

Yes. A more formal version might be:

• אם ההסבר של המורה אינו ברור, אפשר לבקש דוגמה נוספת.

Differences:

• אינו ברור instead of לא ברור
  
  • more formal/written
• דוגמה נוספת instead of עוד דוגמה
  
  • slightly more formal

But the original sentence is perfectly correct and very natural.

Yes.

הסבר is a masculine noun, so the adjective agrees with it:

• הסבר ברור = a clear explanation
• ההסבר לא ברור = the explanation is not clear

If the noun were feminine, the adjective would change:

• הדוגמה לא ברורה = the example is not clear

So adjective agreement is important in Hebrew:

• masculine singular: ברור
• feminine singular: ברורה
