This document discusses the three degrees of comparison in English: positive, comparative, and superlative. It provides rules and examples for forming comparisons with adjectives in each degree. The positive degree describes a single person or thing. The comparative degree compares two people or things using suffixes like "-er" and "more". The superlative degree uses the suffix "-est" to compare three or more people or things. Examples are given to illustrate comparisons of adjectives like big, fast, and loud in sentences using the three degrees.
