Like its English cognate, or related word linguistically, "much," the Spanish word mucho conveys the idea of something being great in quantity or degree. Like English,  mucho can be used as an adverb, adjective or pronoun.

Mucho As an Adverb

As an adverb, mucho is frequently translated as "much" or "a lot." Unlike when it is used as adjective and pronoun, the word mucho does not change with gender or number. It can change when it used as an adverb before adjectives or other adverbs to mean "very," in that case, the word mucho is shortened to muy.

However, mucho is used when it stands alone to mean "very," as in answering a question: ¿Estás cansada? Sí, mucho, which means, "Are you tired?" "Yes, very."

Mucho As an Adjective

As an adjective, mucho must agree with the noun it refers to in number and gender. It is typically translated as "much," "a lot of" or "too many"; in plural form, it typically means "many" or "a lot of."
