Questions & Answers about La calidad del pan aquí es mejor.
Why do we use mejor instead of más buena for "better"?
In Spanish, just like in English, some adjectives have irregular comparative forms. Instead of saying "more good" (más bueno or más buena), you use the special word mejor, which means "better".
La calidad is feminine. Does mejor need to change to match its gender?
We are talking about the bread "here" (aquí). Why do we use es instead of está?
Why does the sentence say del pan instead of de el pan?
In Spanish, whenever the preposition de (of) is followed immediately by the masculine article el (the), they must combine to form the contraction del. So "of the bread" is always del pan.
