1. Adjectives Comparative
   1. Comparative adjectives are used to compare a certain characteristic or quality between two or more things, animals or people.
   2. By making comparisons, we can highlight the superiority, inferiority or equality of quality of one to another. The structure of each of these degrees of comparison is different.
      1. Inferiority comparatives.
         1. To form this type of comparison we can use the conjunctions "not as ... as" or "less ... than". In both cases, the adjective is in the positive degree.
            1. Examples:
            2. Mark is not as fast as Juan.(Mark no corre tan rápido como Juan.)
            3. Sue’s room is less clean than Angela’s.(La habitación de Sue no es tan limpia como la de Angela.)
            4. Beth is not as tall as me.(Beth no es tan alta como yo.)
            5. Los Angeles is not as big as New York.(Los Angeles no es tan grande como Nueva York.)
      2. Equality Comparatives.
         1. With the adjective in the positive degree, we use the conjunction "as ... as" to form equality comparisons.
            1. Examples:
            2. Mark is as fast as Juan.(Mark corre tan rápido como Juan.)
            3. Sue’s room is as clean as Angela’s.(La habitación de Sue es tan limpia como la de Angela.)
            4. Beth is as tall as I am.(Beth es tan alta como yo.)
            5. Los Angeles is as big as New York.(Los Angeles es tan grande como Nueva York.)
      3. Comparatives of superiority.
         1. In superiority comparisons, the adjective, which is in the comparative form, is followed by "than."
            1. Examples:
            2. Juan runs faster than Mark. - (Juan corre más rápido que Mark.)
            3. Angela’s room is cleaner than Sue’s. - (La habitación de Angela está más limpia que la de Sue.)
            4. I am taller than Beth. - (Soy más alto que Beth.)
            5. New York is bigger than Los Angeles. - (Nueva York es más grande que Los Angeles.)
2. Comparatives and Superlatives
   1. As we have seen, adjectives describe qualities of nouns. Some of these qualities can vary in degree or intensity. As in Spanish, when we want to make comparisons we contrast qualities or attributes by means of adjectives in their various degrees.
      1. The positive degree of adjectives is the quality in the simplest degree
         1. Examples:
            1. Juan runs fast. - (Juan corre rápido.)
            2. Angela’s room is clean. - (La habitación de Angela está limpia.)
            3. I am tall. - (Soy alto.)
            4. New York is big. - (Nueva York es grande.)
   2. Form
      1. There are some rules to form the comparative and superlative.
         1. For one-syllable adjectives
            1. Comparative
            2. add: "-er" faster
            3. Superlative
            4. add: "-est" fastest
         2. For one-syllable adjectives ending in "e":
            1. Comparative
            2. add: "-r" nicer
            3. Superlative
            4. adds: "-st" nicest
         3. For one-syllable adjectives that end in consonant + vowel + consonant:
            1. Comparative
            2. add: consonant + "-er" hotter
            3. Superlative
            4. adds: consonant + "-est" hottest
         4. For two-syllable adjectives that end in "and":
            1. Comparative
            2. replace "y" with: "-ier"
            3. funnier
            4. Superlative
            5. substitutes "y" for: "-iest"
            6. funniest
         5. For adjectives of two or more syllables:
            1. Comparative
            2. add: "more" / "less"
            3. more beautiful
            4. less beautiful
            5. Superlative
            6. adds: "the most" / "the least"
            7. the most beautiful
            8. the least beautiful
3. Adjectives Superlative
   1. Superlative adjectives express the maximum degree of a characteristic of an element with respect to others of its same group or condition.
   2. The superlative degree denotes quality in the highest degree and as in Spanish, “the” is used before the adjective in the superlative form
      1. Examples:
         1. Juan is the fastest .(Juan es el más rápido.)
         2. Angela’s room is the cleanest.(La habitación de Angela es la más limpia.)
         3. I am the tallest.(Soy el más alto.)
         4. New York is the biggest city in the United States.(Nueva York es la ciudad más grande de los Estados Unidos.)
4. Note:
   1. We can modify a comparative with a quantifier (much, a lot, a little, slightly ...).
      1. Examples:
         1. Juan is a lot faster than Mark.
         2. I am a little taller than Beth.
5. Note:
   1. If the adjective is possessive, "the" is not used. Also, "the" is not used if we compare something with itself.
      1. Examples
         1. His smartest student is Lisa.(Su estudiante más lista es Lisa.)
         2. New York is coldest in January.(Nueva York es más frío en enero.)
6. Note:
   1. Some qualities cannot vary in intensity or degree because they are extreme, absolute, or ranking adjectives. These qualities have no comparative or superlative form.
      1. Examples:
         1. Extremes
            1. freezing (ice cream)
            2. excellent (excellent)
         2. Absolute
            1. dead(muerto)
            2. unique(único)
         3. Classification
            1. married(casado
            2. domestic(doméstico)
