‘Mucho’ vs ‘mucha’ vs ‘muchos’ vs ‘muchas’

In short – ‘mucho’ translates to ‘a lot of’, ‘much’ and ‘many’ in English. As adjectives ‘mucho’ and ‘mucha’ modify SINGULAR nouns (although ‘mucho’ can also be a pronoun AND an adverb) and we use ‘muchos’ and ‘muchas’ when modifying PLURAL NOUNS.

This can be a tricky topic for us learners Spanish, not only because adjectives in Spanish are kinda difficult, but also because there are a lot of rules to remember!

Ready to master these super common Spanish words once and for all?

Let’s get into it!


Mucho’ can be used in the following ways –

1. As an “adjective”.

Tenemos mucho dinero. = We have a lot of money.

2. As a “pronoun”.

Hay mucho por hacer. = There’s a lot to do.

3. As an “adverb”.

El fin de semana descansé mucho. = I rested a lot on the weekend.

‘Muchos’ and ‘muchas’ are generally adjectives used to modify plural nouns –

El hotel tiene muchas amenidades. = The hotel has many amenities.

BUT they can also be “pronouns” (words used to replace nouns) –

Miró a sus alumnos; muchos levantaron la mano. = She looked at her students; many raised their hands.

Mucho’ vs ‘mucha’ vs ‘muchos’ vs ‘muchas

As an adjective

When used as an adjective, ‘mucho’ describes a ‘big quantity’ or an ‘abundance’ of the noun it’s modifying.

Remember: all nouns in Spanish have a gender (either masculine or feminine) and they’re either singular (just one on its lonesome) or plural (many).

And, well, adjectives in Spanish ALWAYS agree in gender and number with the noun they describe / modify.

This means that we have to choose from one of four forms according to the gender and number of the noun –

We use ‘mucho’ with masculine singular nouns.

We use ‘mucha’ with feminine singular nouns.

We use ‘muchos’ with masculine plural nouns.

We use ‘muchas’ with feminine plural nouns.

Let’s dive into some examples –

Suelo ver muchos colibríes a través de mi ventana.

I usually see a lot of hummingbirds outside my window.

Here ‘mucho’ is modifying ‘el colibri

Hay mucha delincuencia en esa zona.

There is a lot of crime in that area.

Here ‘mucha’ is modifying ‘la delincuencia

Hay muchas manzanas en el árbol.

There are a lot of apples on the tree.

Here ‘muchas’ is modifying ‘las manzanas

As you can see in the examples above, when used as an adjective, ‘mucho’ is always placed BEFORE the noun –

El hospital tiene muchos pacientes muchos.

The hospital has many patients.

¡Muchas gracias!*

Thank you very much!

*Erika’s note – saying muchos gracias is a super common mistake that we’ve all probably made at some point or another! Check out our article on the topic to find out more.

All nice and breezy so far?

Unfortunately, it’s not always all that easy to know what gender a noun is.

AND, to add insult to injury, there are even a few feminine nouns in Spanish that are used with the masculine article ‘el’ (sorry, I don’t make the rules!) –

El agua cristalina.

masculine article + feminine noun + feminine adjective

And why’s that exactly?

Well, nouns that begin with a tonic ‘a’ or ‘ha’ (‘tonic’ just means that they’re stressed) are preceded by ‘el’.

This is actually just to avoid a prolonged ‘a’ sound (i.e., ‘la agua’)!

So, nouns like ‘el hambre’, ‘el área’ or ‘el agua’ might trick you (and who could blame you?) into thinking they’re masculine, when they are in fact feminine.

HOWEVER, the adjectives modifying them must still agree with the feminine noun –

Tengo mucho mucha hambre.

I’m very hungry.

Hay mucho mucha agua en mi vaso

There’s a lot of water in my glass.

This might seem overwhelming at first, but with enough practice – basically reading and listening to A LOT Spanish – you’ll get the hang of them and eventually stop second-guessing which adjective to use.

As a pronoun

‘Mucho’ can also work as a pronoun.

It’s used to refer to nouns previously mentioned or implied –

En el supermercado

Alejandra – ¿Tenemos leche en la casa?

Mirabel – Creo que no queda mucha.

At the supermarket

Alejandra – Do we have milk at home?

Mirabel – I don’t think there’s much (milk) left.

Diego – Vamos a comprar sábanas.

Eder – ¡Pero si ya tenemos muchas!

Diego – Let’s go buy sheets.

Eder – But we already have loads (of sheets)!

As you can see, ‘mucho’ as a pronoun also has to agree in gender and number with the noun it replaces.

Oh, and if you wanna describe a group of people, animals, or things of different genders, you should use the masculine plural form ‘muchos’

El Festival Cervantino reúne artistas de todo el mundo. Muchos se preparan todo el año.

The Cervantino Festival brings together artists from all over the world. Many prepare for it all year long.

As an adverb

Finally, ‘mucho’ can also be an adverb.

As an adverb it generally modifies the verb, so it DOESN’T have to agree in gender and number with a noun (yippee!).

Pedro – ¿Te gusta leer?

Ana – ¡Sí, mucho!

Pedro – Do you like to read?

Ana – Yes, a lot!

Trabajamos mucho para que la presentación fuera un éxito.

We worked hard to make the presentation a success.

Estoy entrenando mucho para el maratón de la Ciudad de México.

I’m training a lot for the Mexico City marathon.

No falta mucho para que el avión aterrice.

It won’t be long before the plane lands.

Expressions with ‘mucho’ / ‘muchos’ / etc.

Mucho más, mucho menos

‘Mucho más’ means ‘much more’ in English, and ‘mucho menos’ means ‘much less’.

In these cases, ‘mucho’ is an adjective, so it agrees in gender and number with the noun as per usual –

¡Tengo muchos más amigos que antes!

I have many more friends than before!

Hoy había muchas menos personas en la playa.

There were far fewer people on the beach today.

Mucho mayor / mucho menor

In these phrases ‘mucho’ is actually modifying the comparative adjectives ‘mayor’ (‘bigger’ or ‘older’ in English) and ‘menor’ (‘smaller’ or ‘younger’).

Be careful here because both mucho’ and ‘mayor (or ‘menor’!) generally agree with the noun –

Mis hermanos son muchos mayores que yo.

My brother is much older than me.

Su auto nuevo es mucho menor que el anterior.

His new car is much smaller than the old one.

Final thoughts

Hopefully you’ll now feel much more (or ‘mucho más’) confident when using these super common Spanish words!

It might take a while to start slinging them about like a pro, but if you keep practicing, I’m sure you’ll get there in no time at all.
