יש מישהו נוסף שרוצה לבוא איתנו?

יש is the Hebrew existential word meaning there is / there are.

So יש מישהו נוסף... literally starts as There is someone else... or more naturally in English, Is there someone else... in this question.

Hebrew uses יש very often where English uses there is / there are:

• יש זמן = There is time
• יש בעיה = There is a problem
• יש מישהו בבית = There is someone at home

In a question, Hebrew usually does not need a separate word like do/does.

Because Hebrew does not form questions with do/does/did the way English does.

In Hebrew, a sentence can often become a question just through:

• intonation in speech
• a question mark in writing
• sometimes a question word such as מה, מי, למה, etc.

So:

• יש מישהו נוסף שרוצה לבוא איתנו. = There is someone else who wants to come with us.
• יש מישהו נוסף שרוצה לבוא איתנו? = Is there someone else who wants to come with us?

No extra helper verb is needed.

מישהו means someone / somebody.

נוסף means additional / extra / another.

Together, מישהו נוסף means someone else or another person.

Very literally, it is something like:

• someone additional

But in natural English, someone else is the best equivalent here.

Because in Hebrew, adjectives usually come after the noun they describe.

So:

• מישהו נוסף = someone else
• ספר טוב = a good book
• ילדה קטנה = a little girl

This is the normal Hebrew word order:

• noun + adjective

So even though English says someone else, Hebrew says someone additional with the describing word after מישהו.

Because מישהו is grammatically masculine singular.

In Hebrew, adjectives and verbs often agree in:

• gender
• number

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

• מישהו נוסף

If the noun were feminine, you would use the feminine form:

• מישהי נוספת = another woman / another girl / someone else when referring to a female person

So the form נוסף is based on grammar, not necessarily on the real-life gender of the unknown person.

ש is a shortened form of אשר and means that / who / which.

In this sentence, שרוצה means:

• who wants
• literally that wants

So:

• מישהו נוסף שרוצה = someone else who wants

This ש־ is extremely common in everyday Hebrew and is attached directly to the next word:

• הספר שאני קורא = the book that I’m reading
• הבחור שדיברתי איתו = the guy that I spoke with
• מישהי שיודעת = someone who knows

Because the verb agrees with מישהו, which is singular.

מישהו = someone, so Hebrew treats it as one person:

• מישהו רוצה = someone wants

That is why the verb is רוצה, masculine singular.

Compare:

• מישהו רוצה = someone wants
• מישהי רוצה = someone (female) wants
• אנשים רוצים = people want

Even though English might say Does anyone want..., Hebrew uses singular agreement because מישהו is singular.

For the same reason as נוסף: it agrees with מישהו, which is grammatically masculine singular.

Hebrew present-tense verbs behave a lot like adjectives in this respect.

Forms of want in the present tense:

• רוצה = masculine singular
• רוצה = feminine singular
• רוצים = masculine plural
• רוצות = feminine plural

Here, מישהו takes singular agreement, and masculine is the default grammatical form:

• מישהו נוסף שרוצה...

If you said מישהי, then it would be:

• יש מישהי נוספת שרוצה לבוא איתנו?

לבוא means to come.

The ל at the beginning is the normal Hebrew way to form the infinitive, similar to English to:

• לבוא = to come
• ללכת = to go
• לראות = to see

So:

• רוצה לבוא = wants to come

This is a very common pattern:

• אני רוצה לאכול = I want to eat
• הם רוצים לדבר = they want to speak

איתנו means with us.

It comes from the preposition עם = with, but when Hebrew attaches pronoun endings, this preposition often appears in the form אית־.

So:

• איתי = with me
• איתך = with you (masculine singular)
• איתך = with you (feminine singular; same spelling, different pronunciation in careful speech)
• איתו = with him
• איתה = with her
• איתנו = with us
• איתכם / איתכן = with you all
• איתם / איתן = with them

So לבוא איתנו = to come with us.

איתנו is the normal modern everyday form.

You may sometimes see עמנו, which also means with us, but it sounds more formal, literary, biblical, or elevated.

So in everyday spoken Hebrew:

• לבוא איתנו is what you would usually say

If you are learning modern conversational Hebrew, איתנו is the form to focus on.

Yes, the structure is literally closer to:

• There is someone else who wants to come with us?

But in natural English, we normally turn that into:

• Is there someone else who wants to come with us? or
• Does anyone else want to come with us?

Hebrew often keeps the same basic word order for statements and yes/no questions, while English usually changes the word order.

So the Hebrew structure is normal even though the best English translation uses Is there... or Does anyone else....

Yes. עוד מישהו is very common and often sounds more natural in everyday speech.

So these are both possible:

• יש מישהו נוסף שרוצה לבוא איתנו?
• יש עוד מישהו שרוצה לבוא איתנו?

Both mean roughly:

• Is there anyone else who wants to come with us?

A rough difference:

• עוד מישהו = very common, everyday anyone else / another person
• מישהו נוסף = a bit more formal or slightly more explicit as an additional person

In many situations, native speakers would probably prefer עוד מישהו.

A common pronunciation is:

yesh mishehu nosaf she-rotze lavo itanu?

A more detailed breakdown:

• יש = yesh
• מישהו = mishehu
• נוסף = nosaf
• שרוצה = she-rotze
• לבוא = lavo
• איתנו = itanu

So the full flow is:

yesh mishehu nosaf she-rotze lavo itanu?

In fast speech, the ש in שרוצה is very light and attached closely to רוצה.
