Step-by-step explanation:
Superlative (from Latin superlatīvus) is an adjective that mentions something very large and out of the ordinary, with a maximum degree of excellence.
The degrees of the adjective express the intensity with which the qualities of objects or people are given. In Spanish there are three grades: the positive, the comparative and the superlative, which in turn distinguishes between the absolute superlative and the relative superlative. Only qualifying adjectives can graduate.
