(See examples below) The modifiers that end in -er are called the comparative forms. Examples: long, longer, longest (longest = superlative) cold, colder, coldest (coldest = superlative) good, better, best (This is an irregular form, best = superlative) bad, worse, worst (also an irregular form, worst = superlative)
