Superlatives are used to compare things and say which one is the biggest, strongest, fastest, etc or the most/least. For example:
This is how to form superlatives:
These superlatives are irregular and don't follow the same pattern, eg:
Es la peor asignatura (It's the worst subject).
|el/la mejor, los/las mejores||the best|
|el/la peor, los/las peores||the worst|
|el/la mayor, los/las mayores||the oldest|
|el/la menor, los/ las menores||the youngest|
Change the adjectives in these sentences into superlatives.
Example: La casa es grande (The house is big) → La casa es la más grande (The house is the biggest).
If something is so amazingly good or bad that it can't be compared to anything, then you need the absolute superlative, eg las pizzas son grandísimas (the pizzas are really, really big). This is formed by removing the final vowel from the adjective (if there is one) and adding the ending -ísimo (or -ísima/-ísimos/-ísimas) to make sure it agrees with the noun. For example:
bueno → buenísimo
malo → malísimo
grande → grandísimo
