Like in Spanish, we can compare many adjectives in different ways in English. Here, we are going to discuss it very briefly.
COMPARATIVEWith this, we say something is more... than something else.
There are two ways: for short adjectives we add: -er than....
eg. My house is bigger than your house
For long adjectives, we write more........than
e.g. My house is more beautiful than your house
There are some irregular adjectives: good-better; bad-worse (mejor, peor)
SUPERLATIVEThe superlative form is used to say that something is the most
There are two ways: for short adjectives we add: the adjective -est
e.g. My house is the biggest
For long adjectives we write : the most + adjective
e.g. My house is the most beautiful
There are some irregular adjectives: good-the best (el/la mejor) bad-the worst (el peor)
When we want to say that something is equal to something else we use this structure: as+ adjective+as e.g. My house is as beautiful as your house
