Notes from a Native English Speaker

Comparative adjectives help us to describe how good or bad something is when compared to something else. For example, something is taller than something else. Superlative adjectives help us to describe something as having the most or least of a particular characteristic within a group. This makes it easier and more accurate to talk about and compare things.
