Suffix Ly Y Ful Lesson Plans & Worksheets Reviewed by Teachers - Free Printable

You’re working on a word-building exercise where you need to add -y, -ly, or -ful to the base words listed to form correct, meaningful words.

Let’s go through each one and explain the reasoning:

---

✔ Rules to remember:

- -y: Often turns nouns into adjectives (e.g., “rain” → “rainy”), or describes a state/quality.
- -ly: Usually turns adjectives into adverbs (e.g., “quick” → “quickly”) — often describes *how* something is done.
- -ful: Means “full of” (e.g., “hope” → “hopeful” = full of hope).
