Let’s work through this step by step.
This is a “Prefix Test” worksheet. The goal is to break down each word into three parts:
1.
Prefix – the part at the beginning that changes the meaning (like “un-”, “re-”, “dis-”, etc.)
2.
Root Word – the main part of the word that carries the core meaning
3.
Meaning – what the whole word means, based on the prefix + root
We’ll go one word at a time.

Now, for the sentence part: “Pick one word to write in a sentence.”
You can pick any word from the list. Let’s pick
“unhappy” as an example:
> After losing his toy, the boy felt unhappy.
(You can choose any other word too — just make sure it makes sense!)
