Comparative and superlative adjectives

1. Comparative adjectives compare two things. Superlative adjectives compare more than two things.
2. Commonly, adjectives that contain only one syllable or end in 'y' use 'er' to form comparatives and 'est' to form superlatives. For adjectives ending in 'y', change the 'y' to 'i' before adding the 'er' or 'est'

• old / older / oldest
• young / younger / youngest
• pretty / prettier / prettiest
• long / longer / longest
• short / shorter / shortest
• bright / brighter / brightest
• close / closer / closest
• happy / happier / happiest

3. Adjectives with two or more syllables do not change but instead add 'more' to form comparatives and 'most' to form superlatives

• respectable / more respectable / most respectable
• beautiful / more beautiful / most beautiful
• preferable / more preferable / most preferable
• hardworking / more hardworking / most hardworking

4. Some adjectives have different forms of comparatives and superlatives

• good / better / best
• bad / worse / worst
• little / less / least
• much/many / more / most
• far / further / furthest

5. The word 'than' typically appears in comparative sentences

• Amy is faster than Silvia
• This phone is more expensive than mine

6. Superlatives are typically accompanied by the word 'the'

• Bill is the tallest boy in the neighborhood
• This is the most beautiful song that I have ever heard
