Hello Bob,
First, let's take into account the purpose of an adjective versus and adverb. in simple terms, an adjective describes a noun (a person, place, thing or idea). For example, "The fast car." The subject (noun) is car. The adjective that describes the car is 'fast'. Now, let's look at adverbs. Adverbs modify a verb and usually end in -ly. For example, the car is moving quickly. In this case the verb is 'moving' and the adverb is describing how the car is moving, 'quickly'. In your example, you had the sentence, "You are absolute right." The verb is "are". There is no adjective describing the verb. However, if you ask the question, "What is the word absolute doing?" It is answering the question, "How are you right?" You are absolutely right. Similar to saying, "You are completely right." I hope this helps.
