Comparatives and Superlatives Grammar 1

Adjectives have three forms:
- positive (small)
- comparative (smaller)
- and superlative (the smallest)

We use the comparative form plus than two compare two people or things. For example: This mobile is cheaper than the laptop but it is more expensive than the mp3 player.
We use the superlative form plus of or in to compare three or more people or things. For example: Mark is the smartest boy of all. Patty is the most beautiful girl in town.
We use in when we talk about places.
Adjectives of one or two syllables form the comparative by adding -er and the superlative by adding -est. For example: Light - lighter - lightest
