Educational worksheet on prefixes, root words, and suffixes for students.

Let's solve this worksheet step by step. The goal is to identify the prefix, suffix, and root word for each given word.

🔹 Definitions:

- Prefix: A word part added before the root word that changes its meaning.
- Suffix: A word part added after the root word that often changes the word’s part of speech or meaning.
- Root Word: The base word that carries the core meaning.

Not all words will have a prefix or suffix.

📝 Explanation:

- Words like tallest, younger, and worthless use suffixes to show degree or negation.
- Words like unhappy, ungrateful, and disappear use prefixes to negate or reverse meaning.
- Become, misspoke, and replay use prefixes like be-, mis-, and re-.
- Some words (like become) have prefixes but no suffix; others (like tallest) have suffixes but no prefix.
- Preschool and underground are compound words with prefixes (pre-, under-) but no suffixes.
- Misspoke has both a prefix (mis-) and a suffix (-ed), showing it's past tense and means "spoke wrongly."

This breakdown helps students understand how words are built from smaller parts!
