What is/are the adverb(s) in the following sentence?: He accurately guessed the weather for the whole week.
The adverb is accurately.
In this sentence, "guessed" is the verb. Because an adverb describes a verb the same way an adjective would describe a noun, this would make the adverb "accurately". An easy way to find an adverb in this sentence and any other one would be to ask yourself, "How did he guess the weather?" Answer: accurately. Another example would be in the sentence "She danced gracefully across the room." How did she dance? Gracefully! Therefore, gracefully would be the adverb. Usually if a word ends in "ly," it's an adverb.
