Final answer:
The three most used adjectives are the positive, comparative, and superlative forms. The comparative and superlative forms are definite descriptions.
Step-by-step explanation:
The three most used adjectives are often referred to as the positive, comparative, and superlative forms of the adjective. These forms are used to describe the degree of quality or quantity of a noun.
The positive form is the regular form of the adjective without any comparison. For example, the positive form of the adjective 'good' is 'good.'
The comparative form is used when comparing two nouns. It typically adds '-er' to the end of the adjective. For example, the comparative form of 'good' is 'better.'
The superlative form is used when comparing three or more nouns. It typically adds '-est' to the end of the adjective. For example, the superlative form of 'good' is 'best.'
Both the comparative and superlative forms are considered definite descriptions because they provide more specific information about the degree of the adjective.
