Welcome to the World of Comparisons!
Have you ever tried to decide which phone is better, who is the tallest person in your class, or which subject is more interesting? To do this, we use comparative and superlative forms. In these notes, we will learn how to change adjectives to compare people, things, and even scientific results!
Don't worry if this seems a bit tricky at first. By the end of this page, you’ll be comparing things like a pro!
1. What is "Making Comparison"?
When we talk about the qualities of people or objects, we use adjectives (like fast, heavy, or expensive). When we want to see how these qualities differ between two or more things, we change the form of the adjective.
The Two Main Levels:
1. Comparative Form: Used to compare two things. (A is bigger than B).
2. Superlative Form: Used to compare three or more things, or an entire group. It identifies the "champion" of that quality. (A is the biggest in the world).
Key Takeaway: Use Comparative for 1 vs. 1. Use Superlative for 1 vs. Everyone Else!
2. The Comparative Form (Comparing Two Things)
To make a comparison between two things, we usually follow one of two paths depending on how long the word is.
Short Words (1 Syllable)
For short words, we simply add -er to the end and use the word than.
Pattern: Adjective + -er + than
Example: Joe is taller than his brother.
Example (from your Science Syllabus): The color of the eggshell was lighter than the control egg.
Long Words (2+ Syllables)
If the word is long and sounds "fancy," we don't add letters to the end. Instead, we put the word more in front of it.
Pattern: more + Adjective + than
Example: This book is more interesting than the movie.
Example: Science experiments are more complex than simple math sums.
Memory Trick: Think of -er as standing for "Even moRe."
3. The Superlative Form (The "Top" of the Group)
When something is at the very top or bottom of a scale, we use the superlative.
Short Words (1 Syllable)
Add -est to the end. You must always use the word the before the adjective.
Pattern: the + Adjective + -est
Example: Mount Everest is the highest mountain in the world.
Example: Monday was the coldest day of the week.
Long Words (2+ Syllables)
Use the word most in front of the adjective.
Pattern: the most + Adjective
Example: She is the most intelligent student in the grade.
Example: That was the most exciting football match ever!
Key Takeaway: Always remember the for superlatives! You can't be the champion without the title.
4. Spelling Rules (The "Small Print")
Sometimes, we need to change the spelling slightly before adding -er or -est.
1. Ends in 'e': Just add -r or -st. (Large -> Larger -> Largest)
2. Ends in 'y': Change the 'y' to an 'i'. (Happy -> Happier -> Happiest)
3. Short Vowel + Consonant: Double the last letter. (Big -> Bigger -> Biggest)
Quick Review:
Dry -> Drier (y to i)
Hot -> Hotter (double the consonant)
5. The Irregular "Rule Breakers"
Some words are rebels and don't follow the rules at all. You just have to memorize these three common ones:
1. Good: Better than (Comparative) / The Best (Superlative)
2. Bad: Worse than (Comparative) / The Worst (Superlative)
3. Far: Farther/Further than (Comparative) / The Farthest/Furthest (Superlative)
Did you know? We never say "more better" or "most best." Since better and best are already changed, adding "more" or "most" is like wearing two pairs of sunglasses—it’s just too much!
6. Common Mistakes to Avoid
Mistake 1: Forgetting "than"
Wrong: He is taller his brother.
Right: He is taller than his brother.
Mistake 2: Using -er and "more" together
Wrong: This is more cheaper.
Right: This is cheaper.
Mistake 3: Forgetting "the" in Superlatives
Wrong: He is tallest boy.
Right: He is the tallest boy.
7. Quick Summary Box
Comparison Summary:
- 1 Syllable? Add -er (comp) or -est (super).
- 2+ Syllables? Add more (comp) or most (super).
- Comparing 2 things? Use than.
- Choosing the best? Use the.
- Watch out for Good/Better/Best and Bad/Worse/Worst!
Encouraging Note: If you aren't sure how many syllables a word has, try the "Clap Test." Clap your hands for every "beat" you hear in the word. Tall (1 clap) = Taller. Ex-pen-sive (3 claps) = More expensive!
