Understanding Prefixes

The video tutorial explains the concept of prefixes, which are groups of letters added to the beginning of words to change their meanings. It covers four main prefixes: 're' meaning 'again', 'pre' meaning 'before', 'dis' meaning 'not' or 'opposite', and 'un' meaning 'not' or 'opposite'. Examples are provided for each prefix, such as 'reread', 'preview', 'disagree', and 'untied'. The video concludes with practice exercises to reinforce the understanding of prefixes.
