Two Spanish sentences with "muy" and "mucho"
Two sentences with “muy” and “mucho”

In this lesson, we will learn the difference between muy and mucho, and the types of sentences where we use each word.

Of course we will provide examples to make it clear.

At the end you’ll find a Quiz and an Exercise for practice.


muy means “very”.

We can only place muy before an adjective or an adverb (such as “grande, fuerte, rápido”…).

muy never changes its form. It is always muy:

Tu amigo es muy amable.
Your friend is very nice.

Tus amigos son muy simpáticos.
Your friends are very nice.

Tengo un ordenador muy viejo.
I have a very old computer.

Pablo está muy cansado.
Pablo is very tired.

Ella canta muy bien.
She sings very well.

Patricia conduce muy rápido.
Patricia drives very fast.

muy always needs an adjective or an adverb right after it.

Otherwise, it becomes mucho:

¿Estás muy cansada?
Are you very tired?

Sí, mucho.
Yes, very.


mucho (and its feminine and plural variations) can mean “much, many, a lot, a lot of”.

When mucho is connected to a noun, it needs to match the noun’s gender and number.

This results in 4 possible forms:

  • mucho (masculine singular)
  • mucha (feminine singular)
  • muchos (masculine plural)
  • muchas (feminine plural)


¿Tienes muchos amigos en Madrid?
Do you have many friends in Madrid?

Sí, muchos.
Yes, many. (although the noun is not mentioned, we still mean amigos)

Paco gana mucho dinero.
Paco earns a lot of money. 

Muchas personas quieren trabajar.
Many people want to work.

Conozco muchas.
I know many. (“muchas” is connected to a feminine plural noun, even if we don’t mention it here. For example, it could be ciudades)

María tiene mucha paciencia contigo… ¡mucha!
María has a lot of patience with you… a lot!

But when mucho is not connected to a noun, then it is always mucho, without variation:

¿Corres mucho?
Do you run a lot?

Sí, mucho.
Yes, a lot.

Los niños pequeños duermen mucho.
Small children sleep a lot.

Me gusta mucho jugar a las cartas.
I like playing cards a lot. (be careful: “mucho” is not connected to the noun “cartas”, but to “jugar”. We don’t mean “a lot of cards”)

Me gustan mucho las flores.
I like flowers a lot. (again, “mucho” is not connected to “flores”. We don’t mean “a lot of flowers”)
