Change the “-y” to “-i” and add -er.

  • Happy → happier (e.g., She looks happier today than yesterday.)
  • Busy → busier (e.g., I am busier this week than last week.)

3. Adjectives with Two or More Syllables

Use “more” before the adjective instead of adding “-er.”

  • Beautiful → more beautiful (e.g., This park is more beautiful than the last one.)
