To solve the problem, we need to identify the prefix, suffix, and root word for each given word. Here's a step-by-step explanation and the solution:

Definitions:

- Prefix: A group of letters added to the beginning of a root word to change its meaning.
- Suffix: A group of letters added to the end of a root word to change its meaning or form a new word.
- Root Word: The base part of a word that carries the primary meaning.

Solution:

1. tallest
- Prefix: None
- Suffix: -est
- Root Word: tall

2. younger
- Prefix: None
- Suffix: -er
- Root Word: young

3. become
- Prefix: None
- Suffix: None
- Root Word: become (This is a complete word with no prefix or suffix.)

4. unhappy
- Prefix: un-
- Suffix: None
- Root Word: happy

5. preschool
- Prefix: pre-
- Suffix: None
- Root Word: school

6. disappear
- Prefix: dis-
- Suffix: None
- Root Word: appear

7. underground
- Prefix: under-
- Suffix: None
- Root Word: ground

8. misspoke
- Prefix: None
- Suffix: -ed (Note: "spoke" is the past tense of "speak," but "miss-" is not a suffix here.)
- Root Word: speak (The full analysis would involve recognizing "miss-" as part of the verb conjugation, but for this exercise, we focus on standard prefixes and suffixes.)

9. ungrateful
- Prefix: un-
- Suffix: None
- Root Word: grateful

10. replay
- Prefix: re-
- Suffix: None
- Root Word: play

11. worthless
- Prefix: None
- Suffix: -less
- Root Word: worth
