### Instruction: What is an adverb?
### Response: An adverb is a word or a combination of words that qualified an adjective (e.g. a describing word).  Adverbs can also restrict and limit the meaning of verbs.  An example of how to use an adverb in a sentence is the following: "the roads are very steep and dangerous."  In this example 'very' is the adverb.  Another example is "they are a happily married couple."  Happily is the adverb in this second example.
