Build New Words: Prefixes and Suffixes for Class 6  

This Grade 6 worksheet helps students understand and apply prefixes (like *un-, dis-, re-*) and suffixes (like *-ful, -less, -ly, -er*) to form new words and change word meanings. With identification, blanks, corrections, and word-creation tasks, learners improve their vocabulary and grammar fluency.

Why Prefixes and Suffixes Matter in Grammar?  

Understanding word parts builds word power. For Grade 6 students, this topic is essential because:  
1. Prefixes change the meaning of a word (e.g., *dislike* = not like).  
2. Suffixes change a word’s form or function (e.g., *hopeful* = full of hope).  
3. It strengthens spelling and decoding unfamiliar words.  
4. It supports both vocabulary growth and sentence writing.

What’s Inside This Worksheet?  

This worksheet includes four vocabulary-focused grammar exercises:

🧠 Exercise 1 – Underline the Prefixes and Suffixes  
Students read 10 sentences and underline the words that contain either a prefix or a suffix.  
Example: “She gave me a *hopeful* smile.” → underline *hopeful*

✏️ Exercise 2 – Fill in the Blanks  
Students complete 10 sentences using the correct prefix or suffix form of a base word (e.g., *restart, careless, quickly*).

📋 Exercise 3 – Rewrite the Sentences  
Each sentence includes an incorrect prefix or suffix word. Students must rewrite the sentence with the correct version.  
Example: “She was very hopeless in class.” → “She was very hopeful in class.”

🎨 Exercise 4 – Word Building and Sentence Creation  
Students are given 5 base/root words. For each word, they must create a new word using a prefix, another using a suffix, and then write a sentence using one of the new words (e.g., *dislike, likable*).
