Adjectives and adverbs are among the eight parts of speech in English language. There is a lot of difference between an adjective and adverb on the basis of their usage and types. Adjective is a word that describes, qualifies and identifies a noun or pronoun, whereas an adverb describes a verb, adjective or other adverbs. An adjective usually, but not all the time, comes before the noun or the pronoun which it describes. For example: the leaves of that tree are yellow. Here yellow is the adjective describing leaves (noun). Another difference between adjectives and adverb is that an adjective usually answer one of a few different questions like “What kind?” or “Which?” or “How many?” For example: The beautiful princess wore a silk gown. Beautiful and silk are the adjectives which answer ‘What kind’; whereas an adverb answer to few questions such as “how,” “when,” “where,” and “how much”. For example: The baby slept soundly. The adverb soundly answers to the question ‘how’. Adverbs mostly end in ‘ly’. But there are certain exceptions, in which the ‘ly’ forms adjective rather than adverb – for example, friendly, early etc., whereas adjectives have three forms of expression. They are in positive degree or comparative degree or superlative degree. For example: hot, hotter or hottest. The difference between adjectives and adverbs is that an adjective modifies a pronoun. For example: They had worked all day and they were tired. The adjective, ‘tired’, tells more about the pronoun

The words which describe noun and pronoun are called adjective on the other hand the words which are used to classify verb are known as adverb
