Spanish Grammar tips: Muy vs. Mucho

Through our blog, we will be covering some topics which cause confusion for most learners.

One such question that we are often asked is: When to use ‘muy’ vs. when to use ‘mucho’

Muy vs. Mucho
Both these words convey the idea of something being in great quantity or degree – just like the English words ‘very’ and ‘much’.

These two words (muy and mucho) are usually NOT interchangeable. Let us understand how to use them correctly:


Mucho is closer to the English words ‘much’ or ‘a lot’. It is used with nouns and verbs.

Mucho with nouns: Because it is used with nouns – it changes its gender (and singular/plural form) in agreement to the noun

  1. Juices have a lot of sugar = Jugos tienen mucho azúcar (singular, masculine)
  2. She has a lot of friends = Ella tiene muchos amigos (plural, male/mixed)
  3. I drink a lot of milk = Bebo mucha leche (singular, feminine)

Sugar, friends, milk are all nouns

Mucho with verbs:With verbs, the form of ‘mucho’ does not change

  1. Maria talks a lot = María habla mucho
  2. It rains a lot in Spain = Llueve mucho en España
  3. I love you a lot = Te amo mucho
  4. You work a lot  = Usted trabaja mucho

As you can see: To talk, To rain, To love, and To work are all verbs


Muy on the other hand is closer to the English word very’ and is used with adjectives and adverbs.

Muy with adjectives:

  1. He is very shy = Él es muy tímido
  2. She is very tired = Ella está muy cansada
  3. John is very tall = John es muy alto
  4. I am very well = Estoy muy bien

As you can see, shy, tired, tall, and well are all adjectives. Hence ‘muy’ takes the form of ‘very’ to increase their degree

Muy with adverbs:

  1. He runs very fast = Él corre muy rápido
  2. She talks very slowly = Ella habla muy despacio
  3. I walked very quickly = Caminé muy rápidamente

As you can see, fast, slowly, and quickly are all adverbs

Thus, use ‘mucho’ as you’d use ‘much/a lot’ and use ‘muy’ as you’d use very.


There is only one exception to this rule. When ‘very’ is used as a stand-alone word i.e. it is not used before an adjective or an adverb, then it will translate as mucho

Are you hungry?…Yes, very! = Tienes hambre? … Sí, mucho!

This is because, sentences like ‘Are you hungry?’ literally translate as ‘Do you have hunger?’. Thus, when we answer this question saying ‘Yes, very’ we are actually saying ‘Yes, I have much hunger

Let us look at another example:
Are you tired?… Yes, very = ¿Estás cansada?… Sí, mucho
