“Artificial sweeteners are substances used in place of sugar; they have an intensely sweet taste, but few or no calories.” Which word in the sentence is an adverb?

intensely

Explanation:

Adverbs are words that modify verbs(actions) or adjectives(descriptions). For example: "Caden quickly ate a blue ice cream bar."

"Caden" is the noun. He is a person. Nouns are a person, place, or thing.

"Quickly" is the adverb. It shows how Caden ate the ice cream.

"Ate" is the verb. It is the action. It is what Caden is doing.

"Blue" is the adjective. It describes what Caden is eating.

Now you know the main parts of speech. The adverb describes how something is happening or goes more in depth about what it is. If you look back at the sentence in the question, look for the word that describes how sugar tastes.

"Intensely" is the adverb while "sweet" is the adjective. The answer is "intensely."
