**Comparative and Superlative Forms of Adjectives**

To form the comparative, use **adjective + -er** or **more / less + adjective**. For example, "Instant messaging is **faster** than email."

To form the superlative, use **the + adjective + -est** or **the most / least + adjective**. For instance, "Our online courses are **the most popular**."

Some adjectives have irregular forms. For example, good becomes better and best. Remember to use **than** when comparing two items.
