Comparatives show that something has more of a quality than something else, using suffixes like "-er" or words like "more". Superlatives indicate something has the most of a quality in a group, using suffixes like "-est" or words like "most". Irregular adjectives and two-syllable adjectives are given as examples, along with exercises asking the reader to form comparatives and superlatives.
