✏️ Bonus Section: Write a sentence using a suffix with a root word

Example 1:
*The teacher was very careful when handling the fragile vase.*
→ Root: “care”, Suffix: “-ful” → *careful*

Example 2:
*I walked slowly down the hallway so I wouldn’t wake the baby.*

✔ Final Tip:
Suffixes change the meaning or grammatical function of a word:
- -able / -ible → capable of being (e.g., readable, breakable)
- -ed → past tense verb
- -ful → full of (e.g., joyful, peaceful)
- -less → without (e.g., hopeless, careless)
- -ly → turns adjective into adverb (e.g., quickly, gently)
- -s → plural noun or 3rd person singular verb
