Root Words
The Core of Every WordLearn to break any word into parts — prefix + root + suffix!
📖 Let’s Learn Root Words!
A root word (also called a base word) is the main part of a word that carries its core meaning. Prefixes and suffixes are added to root words to make new words. For example, the root word “play” can become replay, player, playful, playground!
When you understand root words, you become a word detective! You can break apart any long word into its pieces and figure out what it means — even if you have never seen it before!
💡 The Rule
A root word is the base word without any prefix or suffix. Prefix + Root + Suffix = New Word. Example: un (prefix) + help (root) + ful (suffix) = unhelpful.
🎯 Key Concept
🌱 Root: play
🔧 + prefix: replay (play again)
🔩 + suffix: player (one who plays)
🔧🔩 + both: playful (full of play)
