Suffixes & Word Families

📋 What it is

A suffix is added to the end of a word to change its type or meaning (-ful, -less, -ly).

🗣️ Coach says

A SUFFIX at the end changes a word's job. "-ful" means full of (hopeful), "-less" means without (hopeless), "-ly" makes an adverb (quickly). One root can grow a whole family of words with suffixes.

🧠 Memory hook

Suffix (end) changes the word's job. "-ful" = full of, "-less" = without.

😲 Whoa!

From one root like "care" you can build a whole family: careful, careless, caring, uncaring — all with prefixes and suffixes.

✅ Quick check: What does the suffix "-less" mean in "fearless"?
