– Comparative adjectives are used to compare two things or people. For example, “She is taller than me” or “This book is more interesting than that one”. – To form the comparative of most adjectives, you add -er to the end of the adjective. For example, “big” becomes “bigger” and “fast” becomes “faster”. You also need to use the word “than” after the comparative adjective. For example, “He is bigger than his brother” or “She runs faster than him”. – If the adjective has two or more syllables, you usually use the word “more” before the adjective. For example, “beautiful” becomes “more beautiful” and “difficult” becomes “more difficult”. You also need to use the word “than” after the comparative adjective. For example, “She is more beautiful than her sister” or “This test is more difficult than the last one”. – Some adjectives have irregular comparative forms that do not follow the rules above. For example, “good” becomes “better” and “bad” becomes “worse”. You also need to use the word “than” after the comparative adjective. For example, “He is better at math than me” or “She feels worse than yesterday”.
