- Adverb
- Noun
- Adjective
- None of these
The correct answer is “adverb.” The word “Yes” in this context is classified as an adverb because it modifies the entire sentence that follows. It is an adverb of affirmation, expressing consent or agreement with an implied previous question or statement. It answers a question about the truth of the subsequent clause. While it may not fit the typical “-ly” adverb pattern, words like “yes,” “no,” and “maybe” are categorized as sentence adverbs or particles that function adverbially to convey modality (likelihood, permission, affirmation). It is not a noun (a thing), an adjective (a descriptor for a noun), and it is certainly not “none of these” as it has a clear grammatical classification.
