Prefixes for Kids: Game, Meanings and Examples
A prefix is a group of letters added to the start of a word to change its meaning: un + happy = unhappy (not happy), re + do = redo (do again).
Tricks that make it easier
- un- and dis- usually mean not or the opposite: unkind, disagree.
- re- means again: rewrite, replay.
- pre- means before (preview); mis- means wrongly (misspell).
Common mistakes
- Dropping or doubling letters (mispell instead of misspell).
- Using the wrong "not" prefix (unpossible instead of impossible).
- Forgetting that the root word keeps its spelling.
