יש לי שאלה נוספת על השיעור.

Hebrew usually does not use a verb meaning to have the way English does. Instead, it uses a possession structure:

• יש = there is / there exists
• לי = to me / for me

So יש לי שאלה נוספת literally means something like There is to me an additional question.

That sounds strange in English, but it is the normal Hebrew way to say I have an additional question.

A very useful contrast is:

• יש לי... = I have...
• אין לי... = I don’t have...

לי means to me or for me.

It comes from the preposition ל־ meaning to / for, combined with the first-person singular pronoun.

With יש, these forms are extremely common:

• לי = to me
• לך = to you
• לו = to him
• לה = to her
• לנו = to us
• לכם / לכן = to you plural
• להם / להן = to them

So:

• יש לי שאלה = I have a question
• יש לו שאלה = He has a question

Hebrew has no indefinite article. In other words, there is no separate word for a or an.

So:

• שאלה can mean a question or just question
• השאלה means the question

In your sentence, שאלה נוספת is indefinite, so English translates it as an additional question or another question, even though Hebrew does not add a separate word for a/an.

In Hebrew, adjectives usually come after the noun they describe.

So:

• שאלה נוספת = an additional question
• literally: question additional

This is the normal Hebrew word order.

A related rule: the adjective must also match the noun in:

• gender
• number
• definiteness

So if the noun were definite, the adjective would be definite too:

• השאלה הנוספת = the additional question

Because שאלה is a feminine singular noun, and the adjective has to agree with it.

The adjective נוסף changes form:

• נוסף = masculine singular
• נוספת = feminine singular
• נוספים = masculine plural
• נוספות = feminine plural

Since שאלה is feminine singular, you need:

• שאלה נוספת

A good habit in Hebrew is to learn nouns together with their gender, because adjective agreement depends on it.

They are close, but not always identical in feel.

In this sentence:

• שאלה נוספת = an additional question / another question
• עוד שאלה = another question / one more question

Both are natural. But the nuance can be slightly different:

• נוספת often sounds a bit more formal or written
• עוד is very common and conversational

So these are both fine:

• יש לי שאלה נוספת על השיעור
• יש לי עוד שאלה על השיעור

Both mean roughly the same thing here.

This is a common point of confusion.

• נוספת = additional / another one more
• אחרת = different / another in the sense of a different one

So:

• שאלה נוספת = an extra question
• שאלה אחרת = a different question

In your sentence, נוספת fits because the speaker already asked something and now has one more question.

Here, על means about / regarding / concerning.

So:

• על השיעור = about the lesson / about the class

The preposition על has several meanings in Hebrew, depending on context. It can also mean things like on, over, or about.

In this sentence, the meaning is clearly about.

You could sometimes use other expressions too, such as:

• לגבי השיעור = regarding the lesson
• בקשר לשיעור = concerning the lesson

But על השיעור is very natural.

Because the sentence is talking about a specific lesson or class — one that the speaker and listener both know about.

• שיעור = a lesson / lesson / class
• השיעור = the lesson / the class

So:

• על השיעור = about the lesson
• not just about a lesson in general

In context, this often means something like:

• the lesson we just had
• the class we are discussing
• the specific lesson from earlier

Also, שיעור can mean different things depending on context:

• lesson
• class
• lecture
• even a school period

Because לי already tells you who has the question.

Hebrew does not say אני יש לי שאלה. That is not correct.

The normal pattern is simply:

• יש לי שאלה = I have a question

If you want emphasis, Hebrew might move things around, for example:

• לי יש שאלה = I have a question / As for me, I have a question

But in a normal neutral sentence, יש לי is enough, and אני is not needed.

The sentence as written is very natural and neutral:

• יש לי שאלה נוספת על השיעור

But Hebrew does allow some variation, especially for emphasis.

For example:

• יש לי עוד שאלה על השיעור = very natural, conversational
• על השיעור יש לי שאלה נוספת = puts focus on about the lesson
• יש לי על השיעור שאלה נוספת = possible in some contexts, but less neutral

So the original order is the safest one for learners.

Yes. שיעור can mean either lesson or class, depending on context.

So על השיעור could be understood as:

• about the lesson
• about the class

If this is in a school or course context, both are possible. The exact translation depends on what kind of שיעור is being talked about.

That is very normal in Hebrew: one word can cover several English words, and context decides which one sounds best.
