Adverbs can answer questions like these: “How?” (quickly and well) “When?” (tomorrow) “Where?” (home) “To what extent?” (very funny)
Interrogative Adverbs
An interrogative adverb asks a question. The interrogative adverbs are how, when, where, and why.
Conjunctive Adverbs
A conjunctive adverb joins two ideas. It can give emphasis to one of the ideas, or answer the question “How are they related?” Some common conjunctive adverbs are besides, however, indeed, moreover, nevertheless, otherwise, and therefore. A semicolon is used before a conjunctive adverb, and a comma is used after it. See also: Adverbs and Adjectives Versus Adverbs.
