Writing with prefixes and suffixes worksheets | Worsheets library - Free Printable

The worksheet you've uploaded is a Grade 3 vocabulary exercise focused on prefixes and suffixes, specifically how they change the meaning of words. The task asks students to:

1. Write a sentence for each root word.
2. Write another sentence using the same root word with a prefix or suffix (e.g., adding "in-" to make "inactive").

Let’s go through each word and provide example sentences that demonstrate both the base word and its modified form.

---

✔ 1. active

- Root word (active):
*She is very active in her school's drama club.*
*(Meaning: engaged, energetic)*

- With prefix (inactive):
*After the injury, he had to stay inactive for several weeks.*
*(Meaning: not active; resting)*

---

✔ 2. trust

- Root word (trust):
*I trust my best friend to keep my secrets.*
*(Meaning: believe in someone’s reliability)*

- With prefix (distrust):
*She felt distrust toward strangers after the incident.*
*(Meaning: lack of trust)*

---

✔ 3. cancel

- Root word (cancel):
*The teacher had to cancel the field trip due to rain.*
*(Meaning: to stop or end something planned)*

- With suffix (cancellation):
*The cancellation of the concert made fans very disappointed.*
*(Meaning: the act of canceling; noun form)*

---

✔ 4. end

- Root word (end):
*The movie had a surprising end.*
*(Meaning: conclusion or final part)*

- With suffix (endless):
*The homework felt endless, and I couldn’t finish it in time.*
*(Meaning: never ending; continuous)*

📝 Summary of Prefixes/Suffixes Used:

- in- = not (e.g., *inactive*, *distrust* – note: *distrust* uses *dis-* as a prefix meaning “not”)
- -tion = action or process (e.g., *cancellation*)
- -less = without (e.g., *endless*)

> Note: While "distrust" starts with *dis-*, which is also a common prefix meaning "not," it's worth noting that prefixes like *in-*, *dis-*, *un-*, and *non-* often have similar meanings but are used differently depending on the word.
