Questions & Answers about כשיש הרבה אבק בחדר, אני מתעטשת והאף שלי נעשה אדום.

What does כשיש mean, and how is it built?

כשיש is made of two parts:

• כש־ = when
• יש = there is / there are

So כשיש means when there is or when there are.

You can think of כש־ as a shortened form of כאשר, which also means when.

Does יש change for singular and plural?

No. יש stays the same for both singular and plural.

• יש אבק = there is dust
• יש הרבה ספרים = there are many books

Unlike English, Hebrew does not change יש depending on whether the following noun is singular or plural.

Why is it הרבה אבק and not a plural form of אבק?

Because אבק means dust, which is usually treated as an uncountable mass noun, like dust in English.

So Hebrew normally says:

• הרבה אבק = a lot of dust

Even though הרבה often appears with plural count nouns, it can also be used with singular mass nouns like אבק, מים, אוכל, and so on.
