Hay is one of the first words you learn in Spanish, and also one of the weirdest. It is a frozen, irregular form of haber used only in the present indicative to mean "there is" or "there are". Unlike English, hay does not change for singular or plural—it is the same whether you are talking about one thing or a thousand.
For how this extends to other tenses, see Impersonal Haber in All Tenses. For the contrast with estar, see Hay vs Está/Están.
Same form for singular and plural
The single word hay handles everything. You never pluralize it to hayn or anything like that—there is no such form.
Hay muchos libros en la biblioteca.
There are many books in the library.
Both sentences use hay. The difference between "is" and "are" in the English translation is determined by the number of the noun, not by the Spanish verb.
Used with indefinite noun phrases
Hay is almost always followed by an indefinite noun—one that is being introduced to the conversation for the first time, or that is not a specific, known entity. This is typically a noun with an indefinite article (un, una, unos, unas), a number, a quantity expression, or no article at all.
Hay una farmacia cerca de aquí.
There is a pharmacy near here.
En el refrigerador hay leche, huevos y jugo.
In the refrigerator there is milk, eggs, and juice.
Notice that leche, huevos, and jugo have no article at all. When you are introducing several mass nouns or plural indefinite nouns, Spanish often drops the article entirely.
With numbers and quantities
Hay pairs naturally with numbers and quantity words.
Hay veinticinco personas en la sala.
There are twenty-five people in the room.
Hay demasiado ruido en esta calle.
There is too much noise on this street.
Hay pocos estudiantes que hablen tres idiomas.
There are few students who speak three languages.
Questions with hay
To ask "is there..." or "are there...", simply put hay at the start, usually after the question word.
¿Hay algún problema?
Is there any problem?
Notice that in the second example, the word order is hay at the end—after the direct object. This is typical for content questions with hay.
Hay que + infinitive: must, should
A very common construction is hay que + infinitive, which expresses an impersonal obligation: "one must", "it is necessary to", "you have to". It is used when you do not want to single out a specific person who needs to do the action.
This contrasts with tener que (personal obligation) and deber (moral duty):
- Hay que estudiar = "One has to study" (general truth)
- Tengo que estudiar = "I have to study" (my specific obligation)
- Debes estudiar = "You should study" (moral or personal advice)
No hay: negation
Negation of hay works like any other verb—just place no before it.
No hay leche en el refrigerador.
There is no milk in the fridge.
No hay de qué.
You're welcome.
That last expression is a set phrase. Literally it means "there is nothing of which (to thank me)", and it functions as a polite response to gracias.
Common set phrases with hay
Several fixed expressions use hay idiomatically:
- Hay que ver — "you have to see" (often sarcastic, like "can you believe it?")
- No hay manera / no hay forma — "there is no way"
- ¿Qué hay? — a casual greeting, "what's up?"
- Hay de todo — "there is everything" / "you find all kinds"
No hay forma de convencerlo.
There is no way to convince him.
