Explain the concept of comparative and superlative adjectives.

Comparative and superlative adjectives are used to compare and describe the degree of a quality or characteristic possessed by different nouns. Comparative adjectives are used to compare two nouns, while superlative adjectives are used to compare three or more nouns.

Comparative adjectives are formed by adding "-er" to the end of the adjective for short adjectives (e.g., tall → taller) or by using "more" before the adjective for long adjectives (e.g., beautiful → more beautiful). Superlative adjectives are formed by adding "-est" to the end of the adjective for short adjectives (e.g., tall → tallest) or by using "most" before the adjective for long adjectives (e.g., beautiful → most beautiful).

For example, in the sentence "John is taller than Mark," "taller" is the comparative adjective used to compare the height of John and Mark. In the sentence "John is the tallest person in the room," "tallest" is the superlative adjective used to compare John's height with the rest of the people in the room.
