Let’s go step by step to fill in the table.
We are learning about the prefix
dis-, which means
not or
apart.
When we add “dis-” to a word, it changes the meaning — usually to mean the opposite or to break something apart.
We’ll take each word and:
1. Pull off the prefix “dis-”
2. Find the root word (the main part left)
3. Think: What does the whole word mean? (Use “not” or “apart” + root word)
---
Word 1: disagree
- Prefix: dis-
- Root word: agree
- Meaning: not agree → to have different opinions
✔ So:
PREFIX = dis-
ROOT WORD = agree
MEANING = not agree / to have different opinions
---
Word 2: disorder
- Prefix: dis-
- Root word: order
- Meaning: not in order → messy, chaotic, broken arrangement
✔ So:
PREFIX = dis-
ROOT WORD = order
MEANING = not in order / messiness
---
Word 3: disobey
- Prefix: dis-
- Root word: obey
- Meaning: not obey → refuse to follow rules or commands
✔ So:
PREFIX = dis-
ROOT WORD = obey
MEANING = not obey / refuse to follow
---
Word 4: disrespect
- Prefix: dis-
- Root word: respect
- Meaning: not respect → treat someone rudely or without honor
✔ So:
PREFIX = dis-
ROOT WORD = respect
MEANING = not respect / rude treatment
---
Word 5: disinfect
- Prefix: dis-
- Root word: infect
- Meaning: remove infection → clean to kill germs (think: “take away” infection)
Note: Here, “dis-” can also mean “away from” or “remove,” not just “not.” But for this level, we can say:
→ not infected anymore / cleaned to remove germs
✔ So:
PREFIX = dis-
ROOT WORD = infect
MEANING = remove germs / make free from infection
---
Now let’s put it all together neatly.
Final Answer:
| WORD | PREFIX | ROOT WORD | MEANING |
|------------|--------|-----------|-----------------------------|
| disagree | dis- | agree | not agree |
| disorder | dis- | order | not in order |
| disobey | dis- | obey | not obey |
| disrespect | dis- | respect | not respect |
| disinfect | dis- | infect | remove germs / not infected |
*(Note: For "disinfect", you could also write “clean to remove infection” — both are correct at this level.)*
