Superlative adjective practice worksheet with fill-in-the-blank sentences.

Let's solve this "Superlatives" worksheet step by step.

The task is to complete each sentence using the superlative form of the given adjective. Superlatives are used to compare three or more things and show that something has the highest degree of a quality.

🔹 Rules for Superlatives:

- For one-syllable adjectives: add -est (e.g., high → highest)
- For two-syllable adjectives ending in -y: change -y to -iest (e.g., happy → happiest)
- For two-syllable adjectives not ending in -y and three+ syllables: use most + adjective (e.g., expensive → most expensive, difficult → most difficult)

- Watch out for irregular forms like bad → worst, good → best, far → furthest/farthest.
- Use -est for short adjectives, most + adjective for longer ones.
