What is the adverb form of the adjective "serious"?

• A. Seriously
• B. Seriousness
• C. Seriouslike
• D. Seriousful

Answer: (A)

The correct answer is "seriously," which is formed by adding the suffix "-ly" to the adjective "serious." This transformation typically changes an adjective to an adverb, allowing it to modify verbs, adjectives, or other adverbs in sentences. For example, in the phrase "She spoke seriously," the adverb describes the manner in which she spoke. The other options do not appropriately fit the requirement for an adverbial form. "Seriousness" is a noun that refers to the quality of being serious, but it does not function as an adverb. "Seriouslike" is not a standard English formation and does not exist as a recognized word. Similarly, "seriousful" is not a proper word in English, as the suffix "-ful" typically indicates fullness or having a quality, which does not apply here. Therefore, "seriously" is the only correct choice as the adverb form of "serious."
