Let’s go through each word one by one. We’re looking for the
root word — that’s the main part of the word, without any prefix (added at the beginning) or suffix (added at the end).
We’ll break down each word:
1.
preheat → “pre-” is a prefix meaning “before.” The root is “heat.”
2.
unkind → “un-” is a prefix meaning “not.” The root is “kind.”
3.
breathless → “-less” is a suffix meaning “without.” The root is “breath.”
4.
quickly → “-ly” is a suffix that turns adjectives into adverbs. The root is “quick.”
5.
overlook → “over-” is a prefix meaning “too much” or “above.” The root is “look.”
6.
defrost → “de-” is a prefix meaning “remove” or “reverse.” The root is “frost.”
7.
wonderful → “-ful” is a suffix meaning “full of.” The root is “wonder.”
8.
comfortable → “-able” is a suffix meaning “can be done.” The root is “comfort.”
9.
submarine → “sub-” is a prefix meaning “under.” The root is “marine.” *(Note: “marine” means related to the sea — so submarine = under the sea vehicle)*
10.
undersea → “under-” is a prefix meaning “below.” The root is “sea.”
Now let’s write just the root words in order.
Final Answer:
1. heat
2. kind
3. breath
4. quick
5. look
6. frost
7. wonder
8. comfort
