Explanation:
We need to find the
root word for each given word. A root word is the base part of a word that carries the main meaning. Prefixes are added at the beginning (like *pre-*, *un-*, *over-*, *de-*, *sub-*, *under-*), and suffixes are added at the end (like *-less*, *-ly*, *-ful*, *-able*, *-ine*). Our job is:
1. Underline the prefix or suffix in the word.
2. Write only the root word (without the prefix/suffix) in the blank.
Let’s go one by one:
1.
preheat
- *pre-* is a prefix meaning “before”.
- Root =
heat
2.
unkind
- *un-* is a prefix meaning “not”.
- Root =
kind
3.
breathless
- *-less* is a suffix meaning “without”.
- Root =
breath
4.
quickly
- *-ly* is a suffix turning an adjective into an adverb.
- Root =
quick
5.
overlook
- *over-* is a prefix meaning “above” or “beyond”.
- Root =
look
6.
defrost
- *de-* is a prefix meaning “remove” or “reverse”.
- Root =
frost
7.
wonderful
- *-ful* is a suffix meaning “full of”.
- Root =
wonder
8.
comfortable
- *-able* is a suffix meaning “capable of”.
- Root =
comfort
9.
submarine
- *sub-* is a prefix meaning “under**”.
- Root =
marine
10.
undersea
- *under-* is a prefix meaning “below**”.
- Root =
sea
Double-check each:
- preheat → heat
✔
- unkind → kind
✔
- breathless → breath
✔
- quickly → quick
✔
- overlook → look
✔
- defrost → frost
✔
- wonderful → wonder
✔
- comfortable → comfort
✔
- submarine → marine
✔
- undersea → sea
✔
All roots are real words and make sense.
Final Answer:
1. heat
2. kind
3. breath
4. quick
5. look
6. frost
7. wonder
8. comfort
9. marine
10. sea
