Let's solve this grammar exercise on
comparative and superlative adjectives. The task is to complete the table by adding
-er/-ier for the comparative form and
-est/-iest for the superlative form.
We are given examples:
-
kind → kinder → kindest
-
friendly → friendlier → friendliest
Now, let’s go through each adjective one by one and apply the correct rules:
---
1. smart
- Comparative:
smarter (add -er)
- Superlative:
smartest (add -est)
>
✔ Rule: One-syllable words ending in a consonant-vowel-consonant pattern usually double the final consonant before adding -er/-est.
---
2. friendly
- Comparative:
friendlier (already given)
✔
- Superlative:
friendliest (add -iest)
>
✔ Rule: Words ending in -y (especially after a consonant) change y to i before adding -er/-est.
---
3. brave
- Comparative:
braver (add -er)
- Superlative:
bravest (add -est)
>
✔ Rule: One-syllable word ending with a vowel-consonant pattern — add -er/-est directly.
---
4. gentle
- Comparative:
gentler (add -er)
- Superlative:
gentlest (add -est)
>
✔ Rule: One-syllable word — add -er/-est.
---
5. pretty
- Comparative:
prettier (change y to i, then add -er)
- Superlative:
prettiest (change y to i, then add -est)
>
✔ Rule: Words ending in -y (after a consonant) → change y to i before adding -er/-est.
---
6. ugly
