Superlative adjectives worksheet for students to practice forming the superlative form of common adjectives.

To find the superlative form of each adjective, I need to apply the correct spelling rules based on how each word ends. Let me work through them one by one:

1. fat – Short vowel + single consonant → double the consonant and add -est → fattest
2. big – Short vowel + single consonant → double the consonant and add -est → biggest
3. small – Regular short adjective → just add -est → smallest
4. noisy – Ends in -y → change y to i and add -est → noisiest
5. nice – Ends in -e → just add -st → nicest
6. hot – Short vowel + single consonant → double the consonant and add -est → hottest
7. light – Regular short adjective → just add -est → lightest
8. heavy – Ends in -y → change y to i and add -est → heaviest
9. happy – Ends in -y → change y to i and add -est → happiest
10. quiet – Regular short adjective → just add -est → quietest
11. large – Ends in -e → just add -st → largest

Let me verify each one is correct before writing the final answer. All spellings check out against standard English grammar rules for superlative adjectives.

1. fattest
2. biggest
3. smallest
4. noisiest
5. nicest
6. hottest
