What Are Comparative Adjectives Definition Rules and Examples
Comparative adjectives in English grammar help us compare two people, places, or things. These forms are essential for schoolwork, exams, and everyday English. Knowing comparative adjectives makes your writing and speaking clearer, especially for answering exam questions or daily conversations.

How to Form Comparative Adjectives
- Add "-er" to most one-syllable adjectives (e.g., tall → taller).
- Use "-ier" for adjectives ending in -y (e.g., easy → easier).
- Add "more" before most adjectives with two or more syllables (e.g., careful → more careful).
- Change the word completely for irregular adjectives (e.g., good → better, bad → worse).
Make sure never to use both "-er" and "more" together. Say "easier" or "more easy", but not "more easier".
Difference Between Comparative and Superlative Adjectives
| Type | Use | Example |
|---|---|---|
| Comparative | Compares two things | She is taller than me. |

Using Comparative Adjectives in Real Life
Comparative adjectives often appear in exam questions and real conversations. At Vedantu, we recommend using them to describe or compare classmates, favorite movies, or sports results. Always use "than" after the comparative form for direct comparison, like "smarter than" or "more popular than." This clear structure helps in both written answers and speaking tasks.
Common Student Mistakes with Comparative Adjectives
- Don’t use both "-er" and "more" together (wrong: more easier; correct: easier or more easy).
- Remember to use "than" when comparing two things.
- Some adjectives do not take comparative forms (e.g., "unique").
- Some two-syllable adjectives allow both forms: "cleverer" or "more clever."
