יש מגבה וגלגל רזרבי באוטו.

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

So:

• יש מגבה = There is a jack
• יש מגבה וגלגל רזרבי = There is/are a jack and a spare wheel

Unlike English, Hebrew uses the same word יש for both singular and plural existence.

Because יש does not change for number. It can mean both:

• there is
• there are

So even with two nouns, Hebrew still says יש:

• יש ספר = There is a book
• יש ספרים = There are books

In your sentence, יש introduces the existence of both items together.

Hebrew usually does not have a separate word for the indefinite article a/an.

So:

• מגבה can mean a jack
• גלגל רזרבי can mean a spare wheel

If a noun is indefinite, Hebrew simply uses the noun without ה־.

Compare:

• מגבה = a jack
• המגבה = the jack

באוטו means in the car.

It is made of:

• ב־ = in
• ה־ = the
• אוטו = car

When ב־ and ה־ combine, they become בַּ in writing with vowels, usually written simply as באוטו.

So:

• באוטו = in the car

Because the sentence is talking about:

• a jack
• a spare wheel
• in the car

The first two are indefinite, so they do not take ה־. But the car is definite, so Hebrew marks that:

• באוטו = in the car

If you wanted to say in a car, that would normally be:

• באוטו only if the context makes it definite
• more explicitly indefinite: במכונית can also mean in a car, depending on context

Hebrew often relies on context more than English does.

מגבה is a car jack—the tool used to lift the car when changing a tire.

It comes from a Hebrew root related to lifting/raising. In everyday speech, some speakers may also use borrowed words or other terms, but מגבה is a standard Hebrew word.

Because in Hebrew, adjectives usually come after the noun.

So:

• גלגל = wheel
• רזרבי = spare
• גלגל רזרבי = spare wheel

This is the normal noun + adjective order in Hebrew.

Because adjectives in Hebrew must agree with the noun in:

• gender
• number
• definiteness

גלגל is masculine singular, so the adjective is also masculine singular:

• גלגל רזרבי

If the noun were feminine singular, the adjective would usually be feminine too. For example:

• מכונית רזרבית = a spare car

If the noun were definite, both noun and adjective would usually be definite:

• הגלגל הרזרבי = the spare wheel

Literally, גלגל means wheel. In real usage, גלגל רזרבי often refers to the spare wheel/tire kept in a car.

English sometimes distinguishes:

• wheel = the metal wheel
• tire/tyre = the rubber part

Hebrew is often less strict about this in everyday speech. You may also hear:

• צמיג רזרבי = spare tire

So in context, גלגל רזרבי is understood just fine.

That word order is natural in Hebrew. The sentence is structured like this:

• יש = there is/are
• מגבה וגלגל רזרבי = a jack and a spare wheel
• באוטו = in the car

So the sentence first introduces what exists, then gives the location.

Hebrew can also move things around for emphasis. For example:

• באוטו יש מגבה וגלגל רזרבי = In the car, there is a jack and a spare wheel

Both are fine, but the original version is very natural.

A simple pronunciation guide is:

yesh magbeh ve-galgal rezervi ba-oto

A few notes:

• יש sounds like yesh
• ו before גלגל is pronounced ve-
• באוטו sounds like ba-oto
• רזרבי is commonly pronounced roughly re-zer-vi

Pronunciation can vary slightly by speaker and accent, but that guide will be understood.

You replace יש with אין:

• אין מגבה וגלגל רזרבי באוטו

This means There isn’t a jack and a spare wheel in the car or There are no jack and spare wheel in the car, depending on context.

Very often, if you want to sound especially natural when listing missing items, you might say:

• אין באוטו מגבה וגלגל רזרבי

Word order can shift a little, but אין is the key negative form of יש.
