Muy = Very (adverb) Es muy alto - He's very tall Ayer comimos muy tarde - Yesterday we ate very late Mucha/s Mucho/s = Many, a lot / a lot of (Adjective) Hay muchas personas altas - There are a lot of tall people Hay mucha comida - There's a lot of food Mi profesor habla mucho – My teacher talks a lot Hay muchos mundos - There are a lot of worlds Me gusta mucho el helado – I like an ice cream a lot

exactly in the same way English uses the words "very" and "much", where "very/muy" is an adverb and describes a verb and in Spanish (as well as many other languages) the adverb does not take the noun ending, ie: it always stays "muy" regardless of the situation it is describing, whereas mucho/much" is an adjective and describes nouns and takes the adjectival ending of the noun it is describing, ie: mucho tiempo/muchas cosas etc, because it is an adjective, but if this is too complicated and you understand how English works then just follow "muy" for "very" and "mucho" for "much" this will work :) Keep up the good work

Mucho se utiliza para indicar cantidad: Muchas personas. Muy se para calificar, para indicar una cualidad: Muy bueno
