Grammar worksheet for learning about suffixes, focusing on "-est" and "-er" forms, with a poem and fill-in-the-blank questions.

Let’s go through each question one by one. We’re looking for the correct form of the adjective — either the base form, comparative (“-er”), or superlative (“-est”) — depending on what the sentence is asking.

Remember:
- Use “-er” when comparing two things.
- Use “-est” when comparing three or more things, or when saying something is the most/least in a group.
- Some words are irregular (like “good → better → best”), but here we mostly have regular ones.

13. *The bee is ______ than the leaf.*
→ “than” = comparison between two → kinder? Wait — that doesn’t make sense logically. Bees aren’t “kind.” But grammatically, if we follow the pattern, it should be -er. However, “kinder” is not logical here. Let’s check options:
a. kindest → superlative → no “than”
b. kinder → comparative → matches “than”
c. kind → base → doesn’t fit with “than”
So even though it’s weird, grammar says kinder ✔
Answer: b

14. *The sun was ______ today than yesterday.*
