Relative superlative

When you want to compare more than two people or things you will need to use what is called the relative superlative. For example, you might want to say that Rodrigo is the most intelligent student in his class or, on the contrary, that he is the least intelligent student in his class. Use the following formula as a guide:

DEFINITE ARTICLE + (NOUN) + más/menos + ADJECTIVE + de + GROUP

For example:

Rodrigo es el estudiante más inteligente de su clase.
Rodrigo is the most intelligent student in his class.

Rodrigo es el estudiante menos inteligente de su clase.
Rodrigo is the least intelligent student in his class.

In the formula written above the word noun is placed in parenthesis because it is optional. It is also common to hear the last part of the formula (de + GROUP) omitted. In such cases the group is implied, though not stated. For example:

Juan es el más alto.
Juan is the tallest.

The suffix -ísimo can be added to the end of adjectives to express an absolute superlative:

El béisbol me parece aburridísimo.
Baseball seems very boring to me.

Estoy cansadísimo, ya no aguanto más.
I'm extremely tired, I can't take anymore.
