When to Use Muy and Mucho In Spanish

Do you struggle with knowing when to use muy and mucho?

These two words tend to cause an awful lot of confusion among Spanish students.

Both muy and mucho are widely used among native Spanish speakers so it is important you learn not only to differentiate them, but also how to use them correctly.

As complicating as certain grammar rules may seem when it comes to Spanish, in this case they are quite simple and the following rules will help eliminate any doubts.

Muy vs. Mucho | Key Rules

Best Spanish Phrases for Travel


Muy is an adverb that means “very” in English.

An adverb is a word that modifies a verb, another adverb, an adjective, or a phrase or sentence. But NOT a noun.

An adverb typically answers the question “how,” “in what way,” “when,” “where,” and “to what extent?”

You’re going to love this: Muy has NO masculine, feminine, singular, or plural form! This means muy was, is, and will always be muy, no matter what.

These rare certainties are known to happen now and then within the Spanish language so be excited. Enjoy it while you can!

Now let’s dive in...

Muy + Adjective

Hispanics love to emphasize EVERYTHING so it’s a good idea to have muy on your side.

Muy is a sucker for company as it ALWAYS needs to be accompanied by an adjective or an adverb.

muy in Spanish

You have probably heard mucho in expressions like mucho gusto (nice to meet you) and muchas gracias (thank you).

As you know, mucho goes far beyond those boundaries. Mucho is a two-faced word: it can be used as an adjective or as an adverb.

Mucho means a lot, a lot of, and much or many in English.

Mucho - The Adjective

An adjective is a word that modifies a noun.

This means that when mucho is used as an adjective, it will have to match the noun in number (singular, plural) and genre (feminine, masculine).

Consequently, there are four possible scenarios:

  • Mucho  singular masculine => a lot, a lot of, much
  • Mucha singular feminine => a lot, a lot of, much
  • Muchosplural masculine => a lot, a lot of, many
  • Muchas plural feminine => a lot, a lot of, many

Mucho + Noun

This one can’t get any simpler…. That is as long as you don’t forget to match the number and genre.

Here are a few examples of this formula.

Hay mucha gente en el banco. => There are a lot of people at the bank.

Mi madre cocina mucha comida durante las fiestas. => My mother cooks a lot of food during the holidays.

mucho and muy in Spanish

Juan tiene muchos dolores de cabeza. => Juan has many headaches.

Ana recogió muchas manzanas del árbol del vecino. => Ana collected many apples from the neighbor’s tree.

Hoy hace mucho frío. => It is very cold today.

Samuel tiene muchos amigos en la escuela. => Samuel has a lot of friends at school.

top way to learn spanish

El profesor tiene mucha paciencia.

The professor has a lot of patience.

Mucho - The Adverb

Verb + Mucho

When mucho is used as an adverb, it’s always the same. There is no change in gender and number and it’s placed after the verb it modifies.

Let’s look at a few examples.

Me esforcé mucho para conseguir este trabajo. => I tried very hard to get this job.

muy in Spanish

En verano hace mucho calor. => It’s very hot in the summer.

Te quiero mucho. => I love you a lot.

Estudiaron mucho para el examen de español. => They studied a lot for the Spanish exam.

El profesor tiene mucho para hacer. => The professor has a lot to do.

Laura está cansada porque trabaja mucho. => Laura is tired because she works a lot.

When Mucho is not Enough

As I previously mentioned, Hispanics are masters of the art of exaggeration.

When you liked the food your mother-in-law prepared for you “mucho” and you get disappointing looks, it’s time to turn it up a notch.

Use muchísimo to emphasize that something is more than a lot, many, or very.

For example:

Muy and mucho

Durante el verano, en Buenos Aires hace muchísimo calor.

During the summer Buenos Aires is very, very hot.

Susana preparó muchísima comida. => Susana prepared lots and lots of food.

¡La cena me gustó muchísimo! => I liked dinner very, very much!

Tuve muchísima suerte este año. => I was very, very lucky this year.

mucho in espanol

La película tuvo muchísimo éxito. => The movie was extremely successful.

El árbol tiene muchísimas manzanas. => The tree has lots and lots of apples.

Esa universidad tiene muchísimos alumnos. => That university has many, many students.

Let’s look at this particular example:

mucho and muy in espanol

Me gustas muchísimo. => I like you a lot.

If you try to translate “very much,” you will end up with muy mucho, which would be entirely wrong.

DO NOT try to combine the use of muy and mucho.

You don’t like someone muy mucho. You like someone mucho or muchísimo.

So keep that in mind before you go about putting those two words together in a sentence.

Mixing It Up

After practicing with your tutor using muy and mucho in different ways, you will start noticing if and when something doesn’t sound right.

Now that you have this down, let’s make it a bit more fun.

Take a look at this example…

when to use muy

Mucho estudio. Estudio mucho.

Which is the correct sentence?

You guessed it, they both are! But yes, they have different meanings.

Mucho estudio: Mucho (adjective) estudio (noun) => A lot of studying.

Estudio mucho: Estudio (verb) mucho (adverb). => I study a lot.

  1. Great summary, think in the example “En verano hace mucho calor. => It’s very hot in the summer”, mucho is modifying calori & not hace?

  2. Re: muy/ mucho
    I was told “ir” rarely is used in progressive. Un ejemplo en el blog de Victoria, El coche esta’ yendo muy despacio. No, El coche va muy despacio. Puede ayudarme?

  3. The only one I find confusing is using “mucho” with hace calor b/c it means “very” in that respect. But I guess b/c “hot” is the verb…what is it, it’s hot…then “mucho” makes sense.
