Prefix
A morpheme added to the beginning of a word to modify its meaning.
Why it matters
Roughly 75 prefixes generate the majority of derivative English words. Mastering prefixes accelerates vocabulary, spelling, and reading comprehension simultaneously.
Examples
- UN- in 'undo' marks negation
- PRE- in 'prepare' marks 'before'
- RE- in 'redo' marks repetition
Best practices
- Learn prefix meaning, etymology, and a sample family together
- Watch for ambiguous prefixes (in- = 'not' or 'into')
