Should you use mucho or muy? Do you know how to say the Spanish words muy and mucho in English? What is the difference between muy vs. mucho in Spanish?
Simply put, muy in English would be "very" or "really," while mucho in English means "many," "much," or "a lot." However, as these words can wear muchos sombreros (a lot of hats), muy vs. mucho can be un concepto muy difícil (a very difficult concept) for many English speakers.
When muy is accompanied by an adjective, the adjective that modifies the noun must agree with that noun in terms of gender and number. The "good news," however, is that the word muy itself always stays the same, regardless of whether the noun it modifies is singular or plural or masculine or feminine. Let's take a look:
es un artista plástico español muy reconocido.
is a very famous fine art artist.

Just to reiterate, although the adjectives are singular or plural and masculine or feminine, in agreement with their corresponding nouns, the word muy always remains the same.
The word muy in Spanish also remains the same when accompanying an adverb, which modifies a verb, as in the following examples:

When constructing or understanding sentences with muy in Spanish, how will you know whether you are contending with an adjective or an adverb? When you see a word that ends with the suffix -mente (equivalent to -ly in English), as in the examples above, you can be sure you have an adverb. However, as not all adverbs take this form and some words can function as either adjectives or adverbs, depending upon the context, it can sometimes be tough to tell the difference. Let's take a look at an example with the word rápido, which may be used as an adverb in lieu of rápidamente:
porque lo hacen muy rápido.
because they do it very quickly.Play Caption
Like the English word "fast," rápido can function as an adjective when describing a noun (e.g. un carro rápido/a fast car) or an adverb when describing an action (el carro va rápido/the car goes fast) to talk about something that happens "fast" or "quickly." The tricky aspect of this is that, while rápido would need to agree in terms of gender and number when employed as an adjective (e.g. unos carros rápidos), as an adverb, it remains the same (in its masculine singular form) regardless of the number of people or objects performing the action. Let's see one more example:
Vamos a trabajar muy fuerte.
We're going to work very hard.Play Caption
Note that as always, the word muy is unchanging, and because fuerte (strong, hard, etc.) works as an adverb here, it remains unchanged, in its singular form, as well. Were it an adjective, on the other hand, gender and number would need to be taken into account, as in the example "Somos muy fuertes" (We are very strong).
Moving on to the word mucho in Spanish, taking into account what we have learned thus far regarding adjectives and adverbs, let's examine how this word can function as either of these parts of speech. To start, when mucho functions as an adjective, it must agree in terms of number and gender with the noun it modifies. Let's look:
¿Sí? No tengo mucho tiempo libre ahora.
Right? I don't have a lot of free time now.

As you can see in these examples that employ masculine singular/plural and feminine singular/plural nouns, the form mucho takes (mucho, muchos, mucha, or muchas) changes in accordance with the noun it modifies.
In contrast, when mucho functions as an adverb, modifying a verb, it is always mucho in the singular/masculine form, and the gender/quantity of the noun or verb has no effect on it. Let's look at some examples:
¿Se utiliza mucho el ajo en los platos peruanos?
Is garlic used a lot in Peruvian dishes?

To conclude our discussion on muy vs. mucho, note that the word mucho and its corresponding feminine/plural alternatives can be used as pronouns to replace nouns that have been mentioned or implied. Notice that the pronoun forms of mucho must agree in gender and number with the nouns they replace, as follows:
¿Se encuentran aquí buenas cositas o no, buenas gangas? -Sí, sí, sí. -¿Sí? -Muchas.
Can you find good stuff here or not, good bargains? -Yes, yes, yes. -Yes? -Many.

While you can clearly see in the first two examples that the word mucho changes forms (to mucha and muchas) to agree with the feminine singular and plural nouns it replaces (cositas/gangas and gente), the third example is notable because the noun being replaced by the masculine plural form muchos is not immediately apparent. However, since the conversation in question, which began several captions earlier, involves cars (the masculine plural noun, los coches), the masculine plural form muchos must be utilized to express the idea of "many" in this context.
