Comparisons in English involve showing the similarities or differences between two or more things.
1. Comparative Adjectives:
- Used to compare two things.
- It is often formed by adding “-er” to the adjective or using “more” before it.
- They often use the word “than” to introduce the second thing being compared.
- Examples:
- This car is faster than that one.
- She is more intelligent than her brother.
- Taller: My brother is taller than me.
- Smaller: This box is smaller than the one I lost.
- Faster: Your dog runs faster than Jim’s dog.
- Higher: The rock flew higher than the roof.
- More important: Homework is more important than watching television.
- Happier: Watching television makes me happier than doing homework.
- More expensive: My necklace is more expensive than my bracelet.
- Worse: I got a C on my essay, which is worse than the 100% I got last time.
- Cheaper: To save money, I am searching for the cheapest textbooks.
- Better: My grandmother’s chocolate chip cookies are the best.
- Bumper: Driving on a dirt road is bumpier than driving on asphalt.
Forming comparatives:
- Short adjectives: Usually add “-er” (e.g., tall – taller, fast – faster).
- Longer adjectives: Usually use “more” before the adjective (e.g., important – more important, expensive – more expensive).
- Irregular adjectives: Some adjectives have irregular comparative forms (e.g., good – better, bad – worse).
It’s important to clarify that “irregular adjectives” is not a standard grammatical term. Irregularity typically applies to verbs (like “go” – “went” – “gone”) and nouns (like “child” – “children”). Adjectives, however, have irregular comparative and superlative forms.
Key Points:
- “Good,” “bad,” “little,” “much,” and “many” are the most common irregular adjectives.
- “Far” has two sets of comparative and superlative forms:
- “Farther” and “farthest” generally refer to physical distance.
- “Further” and “furthest” can refer to metaphorical distance or degree.
- “Old” also has two sets:
- “Older” and “oldest” are used for general comparisons.
- “Elder” and “eldest” are typically used for family relationships (e.g., “my elder brother”) or in formal contexts.
Why are they irregular?
These adjectives don’t follow the regular patterns of adding “-er” and “-est” or using “more” and “most.” They have completely different forms for their comparative and superlative degrees.
2. Superlative Adjectives:
- Used to compare three or more things, indicating the one with the most or least of a certain quality.
- It is often formed by adding “-est” to the adjective or using “most” before it.
- They usually use the word “the” before the adjective.
- Examples:
- He is the tallest boy in the class.
- This is the most expensive restaurant in town.
- Tallest: Mount Everest is the tallest mountain in the world.
- Smallest: This is the smallest dog I’ve ever seen.
- Happiest: She is the happiest person I know.
- Most important: Education is the most important thing in life.
- Most expensive: This is the most expensive car in the showroom.
- Worst: This is the worst movie I’ve ever watched.
- Best: My grandmother makes the best cookies.
- Most beautiful: She has the most beautiful eyes.
- Fastest: Usain Bolt is one of the fastest runners in the world.
- Strongest: The lion is the strongest animal in the jungle.
Forming superlatives:
- Short adjectives: Often add “-est” (e.g., tall – tallest, fast – fastest).
- Longer adjectives: Usually use “most” before the adjective (e.g., important – most important, expensive – most expensive).
- Irregular adjectives: Some adjectives have irregular superlative forms (e.g., good – best, bad – worst).
3. Using “as…as”:
- Used to show that two things are equal in some way.
- Examples:
- She is as tall as her mother.
- The movie was as interesting as the book.
Key points:
- Structure: The basic structure is “as + adjective/adverb + as.”
- Equality: It’s used to show that two things are equal in some way.
- Inequality: You can use “not” before the first “as” to show that two things are not equal.
Showing equality:
- She is as tall as her brother. This means she has the same height as her brother.
- This book is as interesting as the last one I read. This means the books are equally interesting.
