Lesson Summary
A prefix is a word part added to the beginning of a root word that changes its meaning.
Explanation
The prefix 'un-' means 'not,' so 'unhappy' means 'not happy.' The prefix 're-' means 'again,' so 'rewrite' means 'to write again.' The prefix 'pre-' means 'before,' so 'preview' means 'to view before.' The prefix 'dis-' means 'not' or 'opposite,' so 'disagree' means 'to not agree.'
