Adjective and Adverb difference
Adjectives are used to describe or give information about things, ideas and people: nouns or pronouns.
an expensive car, a brilliant idea, a beautiful girl, she is careful.
Adjectives generally answer the question what kind.
Adverbs are used to modify:
a. a verb (She sings beautifully.)
b. an adjective (She is very beautiful.), or
c. another adverb (The car goes very fast.)
Time, place, manner, frequency, and degree adverbs (early, there, slowly, often, almost) describe when, where, how, and how often  something is done.
Many adverbs are formed by adding -ly to an adjective (slow - slowly, quick - quickly).
