We often use comparisons because we want to talk about the differences between people, places, and things.
Here is an example:
Janet’s house is bigger than Tom’s.
Tom’s house is a lot smaller than Janet’s.
3. Janet’s house is fancier and more elaborate than Tom’s house.
Tom's house Janet's house
The comparative forms from the previous example are: - bigg er than -small er than -fanc ier than - more elaborate than So . . . When do we use “–er” and when do we use “more?” Here are the rules
Rule 1: How many syllables are the words: “ big” and “ small ?” 1 For 1-syllable adjectives, JUST add “er” to the end. Example: Tom is smarter than Joe. *If the 1-syllable adjective ends with the letter “e,” JUST add “r” to the end. Examples: nicer wiser **If the 1-syllable adjective has a C-V-C pattern, Double the consonant and add “er .” Examples: San Francisco is wetter than San Diego. San Diego is bigger than San Francisco.
Rule 2: For adjectives that end with the letter “y,” DROP the “y” and add “ier .” Examples: Adjective = fancy Janet’s house is fancier than Tom’s. Adjective = pretty Janet’s house is prettier than Tom’s. Adjective = friendly Alison is friendlier than Susan.
Rule 3: How many syllables is the word: elaborate ? 4 (more than 1) For adjectives that are 2 or more syllables, use “ more” + the adjective to make the comparative form. Examples: Adjective = elaborate Janet’s house is more elaborate than Tom’s. Adjective = comfortable This chair is more comfortable than that chair.
Rule 4: Irregular comparatives: You MUST memorize these! Examples: good = better than far = farther (further) than bad = worse than Adjective = good Sara’s grades are better than Michael’s.
Grammar Rule: Never use both MORE and “ER!” Incorrect: Lisa’s job is more better than mine. Correct: Lisa’s job is better than mine.
Rule 5: Using “less than” Sometimes we compare two things by using “less than.” To do this, use LESS + adjective + THAN When using “less than,” the adjective DOES NOT CHANGE Examples: He is LESS energetic than my other teacher. This class is LESS crowded than the other one. New York City is LESS polluted than Los Angeles.
Review of Rules less quiet than less crowded than quiet crowded 5. Less Than better than worse than farther/further than good bad far 4. Irregular forms: (memorize) more polite than more beautiful than more important than polite beautiful important 3. Adjectives with two or more syllables: use “more” friendlier than busier than easier than friendly busy easy 2. Adjectives that end in “Y”: drop “Y”, add “ier” older than bigger than cheaper than old big cheap 1. Adjectives with one syllable: add “er” COMPARATIVE ADJECTIVE Rule . . .

3. A dog is usually _______________ (friendly) than a cat.
4. It is _____________ (hot) today than it was yesterday.
