Comparative and Superlative Adjectives - Grammar Worksheets for ... - Free Printable

Let's solve this step-by-step. The task is to complete the sentences using the superlative forms of the given adjectives.

🔹 What are superlative forms?

The superlative form is used to compare three or more things and indicates that something has the highest degree of a quality.

- For one-syllable adjectives: add -est
→ *fast* → fastest, *small* → smallest
- For two-syllable adjectives ending in -y: change y to i and add -est
→ *smart* → smartest, *beautiful* → most beautiful
- For longer adjectives (more than two syllables): use most / least + adjective
→ *good* → best, *bad* → worst, *expensive* → most expensive

Also, remember:
- Use "the" before superlative adjectives.
- Some irregular adjectives have special forms:
→ *good* → best, *bad* → worst, *far* → farthest/furthest
