Adjectives in English as well as in Spanish may be presented in the comparative form. The following constructions may be used to indicate adjectival comparison:
más + adjective + que
more + adjective + than
menos + adjective + que
less + adjective + than
tan + adjective + como
as + adjective + as
Mi hermana es más simpática que la tuya.
My sister is nicer than yours.
Esta película es menos interesante que la de ayer.
This movie is less interesting than the one from yesterday.
Las frutas en el almacén no son tan frescas como en el mercado.
The fruit at the grocery store aren't as fresh as at the market.
In addition to these three constructions, you can use mejor/ mejores (better), peor/peores (worse), mayor/mayores (older), and menor/menores (younger):
Las obras de Shakespeare son mejores que muchas obras modernas.
Shakespeare's plays are better than many modern plays.
Mi escritura es peor que la suya.
My handwriting is worse than hers.
Todos mis primos son mayores que yo.
All of my cousins are older than me.
Su gerente es menor que él.
His manager is younger than him.
In addition to comparative forms, English also has a superlative form: compare “better” and “best,” “more” and “most,” “higher” and “highest,” and so on. Only longer English adjectives require use of another word: “more interesting” and “most interesting,” “more frequent” and “most frequent.”
In Spanish, all adjectives require the use of más (most) and menos (least):
Tengo el amigo más amable del mundo.
I have the nicest friend in the world.
Ella es la pintora menos talentosa de la universidad.
She is the least talented painter in the university.
