יש סכנה בכביש.

יש is the Hebrew word used to express there is or there are.

So:

• יש סכנה = there is danger
• יש מכונית = there is a car
• יש אנשים = there are people

In יש סכנה בכביש, יש introduces the existence of something: danger.

In Hebrew, present-tense sentences often do not use a word equivalent to English is/are.

But יש is a special case: it is used for existence.

So Hebrew distinguishes between:

• הכביש מסוכן = The road is dangerous
  (description)
• יש סכנה בכביש = There is danger on the road
  (existence/presence of danger)

So even though English uses is in both kinds of sentences, Hebrew handles them differently.

סכנה means danger.

It is a feminine singular noun.

You may also see it in expressions like:

• סכנה גדולה = great danger
• בלי סכנה = without danger
• מצב סכנה = a dangerous situation / state of danger

In this sentence, it is being used in a general sense: danger is present.

Because after יש, Hebrew usually introduces something indefinite, not the something.

So:

• יש סכנה בכביש = There is danger on the road
  (natural)
• יש מכונית בחוץ = There is a car outside

Using יש with a definite noun like הסכנה is much less common and usually sounds unnatural unless the context is very specific.

If you want to talk about the danger, Hebrew would more naturally use a different structure, for example:

• הסכנה נמצאת בכביש = The danger is on the road
• הסכנה בכביש גדולה = The danger on the road is great

בכביש means on the road or in the road, depending on context.

It is made from:

• ב־ = in / on / at
• כביש = road

So literally it is in/on the road.

But there is an important detail: the form בכביש here is understood as בַּכביש = on the road (with the definite article the built in).

That happens because:

• ב + ה + כביש becomes בכביש
• this is pronounced ba-kvish

So this is not just on a road, but usually on the road / on the roadway.

The Hebrew preposition ב־ is broader than any single English preposition.

Depending on context, it can mean:

• in
• on
• at

Examples:

• בבית = in the house / at home
• בשולחן (less common in modern speech for physical location) / על השולחן = usually on the table
• בכביש = on the road / in the road

So you should not expect a perfect one-to-one match with English. In this sentence, English naturally says on the road.

Yes, both are possible.

• יש סכנה בכביש = neutral, standard way to say it
• בכביש יש סכנה = puts more emphasis on on the road

Hebrew word order is somewhat flexible. Moving בכביש to the front can highlight the location.

So:

• יש סכנה בכביש = There is danger on the road
• בכביש יש סכנה = On the road, there is danger

Both are grammatical; the difference is mainly emphasis and style.

A natural pronunciation is:

yesh sa-ka-NA ba-KVISH

More closely:

• יש = yesh
• סכנה = sakaná (stress on the last syllable)
• בכביש = bakvish (stress on the last syllable)

A rough full pronunciation: yesh sakaná bakvísh

Two useful notes:

• כּ / כ in כביש is pronounced like k here
• the stress in both סכנה and בכביש is at the end

Yes, סכנה is singular.

Hebrew often uses a singular abstract noun where English also uses a singular abstract noun:

• יש סכנה = there is danger

This means danger exists as a general condition. You do not need a plural.

If you wanted plural, you could say:

• יש סכנות בכביש = There are dangers on the road

But that sounds more like multiple specific hazards, while יש סכנה בכביש is the normal general warning.

It can work as both, but it sounds especially natural as a warning.

For example, it could appear in speech or on a sign to mean:

• There is danger on the road
• Danger on the road
• The road is dangerous (as a practical translation, though not literal)

Hebrew often uses short existential sentences like this for alerts and notices.

You would say:

אין סכנה בכביש.

Here:

• יש = there is / there are
• אין = there is no / there are no

So:

• יש סכנה בכביש = There is danger on the road
• אין סכנה בכביש = There is no danger on the road

This is a very useful pair to learn together.

Yes, and the meaning is related, but the wording is different.

• יש סכנה בכביש = There is danger on the road
• הכביש מסוכן = The road is dangerous

The first focuses on the presence of danger. The second directly describes the road as dangerous.

In many real situations, both could fit, but they are not exact grammatical equivalents.

כביש usually means road, highway, or roadway, especially the part used by vehicles.

For street, Hebrew often uses רחוב.

So compare:

• כביש = road / roadway
• רחוב = street

That means יש סכנה בכביש suggests danger in the roadway or traffic area, not just somewhere on a street in the general neighborhood.
