It is important to be able to know how to say “there is” or “there are” in Spanish because it will be the basis upon which you can start describing places. In Spanish the verb to use is Haber. This verb, however, is irregular. For now, though, you don’t need to worry yourself with the conjugations. All you need to know is the following:
Hay = There is/There are
That’s right, in Spanish there is one verb conjugation to express both “there is” and “there are.” Nice, eh? Let’s look at some examples:
Hay tres niños en mi casa. (There are three kids in my house).
Hay un libro en la mesa. (There is a book on the table).
As you can see, Hay is used for both - there is and there are.
