Build and Break Words: Mixed Prefix and Suffix Review for Class 6

This Grade 6 worksheet provides a thorough review of both prefixes and suffixes — the word-building blocks that transform base words into new words with altered meanings. Students work with common prefixes like un-, re-, dis-, mis-, pre-, post-, and inter-, as well as suffixes like -ness, -less, -ful, -able, and -ment. Through five carefully designed activities — matching words to their base forms, sorting words by prefix or suffix, fill in the blanks, multiple choice questions, and sentence rewriting — learners develop a strong command of how affixes change word meanings and functions. Each exercise challenges students to identify the correct prefix or suffix in context, recognise base words, and apply their understanding to create accurate and meaningful sentences. This worksheet is an essential resource for building vocabulary, improving spelling, and strengthening word-formation skills for Grade 6 students.

Why Prefixes and Suffixes Matter in Grammar?

Prefixes and suffixes are fundamental to English vocabulary development and word formation. For Grade 6 learners, reviewing these affixes is important because:
1. Prefixes change the meaning of a word (e.g., happy → unhappy), while suffixes often change its part of speech (e.g., teach → teacher).
2. Knowing common affixes helps students decode unfamiliar words independently during reading.
3. They are frequently tested in grammar assessments, spelling bees, and competitive English exams.
4. A strong understanding of word formation supports creative writing, comprehension, and communication skills.

What's Inside This Worksheet?

This worksheet includes five grammar-rich activities that build fluency with prefixes and suffixes:

Exercise 1 – Match Words to Base Words
Students match each prefix-suffix word on the left to its correct base word on the right. For example, ""unhappiness"" matches with ""happy,"" ""reusable"" matches with ""use,"" and ""impossible"" matches with ""possible."" This activity strengthens base-word identification skills.

Exercise 2 – Sort the Words
Students sort words into Prefix Added and Suffix Added categories. Words like unkind, reread, disobey, and misplace go under Prefix Added, while words like darkness, careless, playful, and hopeful go under Suffix Added. This reinforces the difference between prefixes and suffixes.

Exercise 3 – Fill in the Blanks
Students choose the correct word with the right prefix or suffix to complete each sentence. For example: ""Anjali said the long instruction was very ___ (unreadable/unreading) to follow."" The correct answer is ""unreadable."" This builds contextual application of affixes.

Exercise 4 – Multiple Choice Questions
Students pick the correct altered word from four options. For example: ""He spoke very ________. a) darkness b) disconnected c) sadness d) unkindly."" The correct answer is ""unkindly."" This sharpens quick recognition of affixed words.

Exercise 5 – Rewrite the Sentences
Students rewrite each sentence by correcting the wrongly formed prefix-suffix word. For example: ""Anjali said the instruction was completely unread by students."" becomes ""Anjali said the instruction was completely unreadable by students."" This exercise builds editing and vocabulary accuracy skills.
