When to use muy

In Spanish, muy is an adverb that intensifies the qualities expressed by an adjective or another adverb. In other words, it highlights how something or someone is, or how an action is done. 

Check these examples and see the characteristics that muy is emphasizing: 

[Subject] + [verb conjugated] + muy + [adjective/adverb]

El internet está muy lento.
The internet is very slow

Vanessa e Ivonne son muy altas.
Vanessa and Ivonne are very tall.

Mis hermanos comen muy rápido.
My brothers eat very fast.

Pierre habla español muy bien.
Pierre speaks Spanish very well.

Ten cuidado, la sopa está muy caliente.
Be careful, the soap is very hot

Take Note: Muy is a Spanish adverb, and as such, it doesn’t work with nouns—only with adjectives or other adverbs. As a result, it maintains a single form and does not change based on gender or number.

When to use mucho in Spanish

Mucho is a word that relates to quantities. As an adverb, it expresses the degree or intensity of an action: 

[Verb conjugated] + mucho

La quiero mucho
I love her very much

¿Esa cámara te costó mucho?
Did that camera cost you much?

¡Tu hermano come mucho y muy rápido!
Your brother eats a lot and very fast!

When working with nouns, mucho acts as a Spanish determiner, indicating the quantity of something. Because it’s providing information about nouns, in this context, mucho has feminine and plural forms. 

[Verb conjugated] + [mucho*] + [noun]

No tengo mucho tiempo
I don’t have much time

Compré muchos paquetes de galletas.
I bought many packages of cookies.

Susana tiene muchas camisas rosas. 
Susana has many pink shirts. 

Hablar en público me da mucha vergüenza
Speaking in public makes me very embarrassed

Check the last example. Notice that in Spanish we use the word mucha because we’re measuring a feminine noun (vergüenza). However, in English, we use ‘very’ to emphasize an adjective (embarrassed). 

This distinction is particularly common when using the verb dar to express emotions

Take Note: In Spanish, using ‘muy mucho’ is incorrect because muy is used to intensify qualities, not quantities.To express very much, you can simply say ‘mucho’ or use the superlative form muchísimo. 

Te amo muchísimo
I love you very much.
