An adjective gives more information about a pronoun or a noun.
1. She is nice. ("Nice" is an adjective that gives more information about the pronoun, "she.")
2. The pretty little girl was wearing a beautiful red dress. "Pretty" and "little" are adjectives that give more information about the noun, "girl." "Beautiful" and "red" are "adjectives" that give more information about the noun, "dress."
An adverb most often gives more information about (or describes) verbs and adjectives. Adverbs most often answer questions such as "How?" & "When?"
1. She walks slowly. "Slowly" is an adverb that describes the verb, "walks." It answers the question, "How does she walk?"
2. He will arrive soon. "Soon" is an adverb that describes the verb, "arrive." It answers the question, "When will he arrive?"
3. Those flowers are really pretty. "Really" is an adverb that describes the adjective, "pretty." It answers the question, "How pretty are those flowers?"
Most adverbs are formed by starting with an adjective and adding "ly."
beautiful -> beautifully
helpful -> helpfully
creative -> creatively
When you are speaking or writing and are looking for a word that provides more information, choose the correct word based on whether you are describing a noun/pronoun or an adjective/adverb.
