Let’s go through each word one by one. We need to find the
root word — that’s the main part of the word, without any prefix (added at the beginning) or suffix (added at the end).
---
1.
breathless
→ “-less” is a suffix meaning “without.”
→ Root word:
breath
2.
quickly
→ “-ly” is a suffix that turns an adjective into an adverb.
→ Root word:
quick
3.
overlook
→ “over-” is a prefix meaning “too much” or “above.”
→ Root word:
look
4.
defrost
→ “de-” is a prefix meaning “remove” or “reverse.”
→ Root word:
frost
5.
wonderful
→ “-ful” is a suffix meaning “full of.”
→ Root word:
wonder
6.
comfortable
→ “-able” is a suffix meaning “can be done.” But wait — actually, “comfort” is the root, and “-able” is added to it. Sometimes we drop the ‘e’ when adding suffixes, but here “comfort” stays mostly intact.
→ Root word:
comfort
7.
preheat
→ “pre-” is a prefix meaning “before.”
→ Root word:
heat
8.
unkind
→ “un-” is a prefix meaning “not.”
→ Root word:
kind
9.
submarine
→ “sub-” is a prefix meaning “under.”
→ Root word:
marine
10.
undersea
→ “under-” is a prefix meaning “below.”
→ Root word:
sea
