Explanation:
Superlatives of adjectives and adverbs can be formed by suffixes; there are some cases of superlatives of nouns (for example general -> generalísimo) but they are very rare.
Absolute superlatives can be regular or irregular. In regular superlatives, the superlative degree is formed by adding the suffix "-ísimo/-ísima" to the root that the adjective presents in a positive degree.
Adjectives whose root ends in -c take -qu- in the superlative, and also take one -u- those that have the root ending in -g:
rico -> riquísimo
largo -> larguísimo
We can also find superlatives in this way:
EL / LA / LOS / LAS + LAS + ADJECTIVE + DE
El general Pereyra fue el guerrero más valiente de su generación.
