In English, adjectives and adverbs can be inflected into comparative and superlative forms. Comparative inflections serve the purpose of showing the degree to which one thing compares to another, while the superlative shows the greatest form of an adjective. An example of the comparative inflection is the word "more" in this sentence: "It costs her more to rent than to buy." The comparative is
. usually completed using a subordinating conjunction, for instance the word "than" in the previous example. When a subordinating conjunction is not used, the inflection is called the "Null Comparative." Examples of this are present largely in advertising, with statements like "Now contains 50% more" where the item being referred to is not explicitly stated. The superlative inflection is similar to the comparative, but does not require a comparison to be explicitly made. Superlative adjectives are those that express the greatest degree of the adjective, or an absolute adjective. These are examples of superlative adjectives: unique, complete, full, empty, best, worst, most, least, largest, and smallest.
