Understanding Prefixes in English

The video tutorial introduces prefixes, which are letters added before root words to form new words with different meanings. It covers several prefixes, including 'mis-' meaning not or wrongly, 'pre-' meaning before, 're-' meaning to do again, 'un-' meaning not, 'non-' meaning not, and 'dis-' meaning negative or opposite. Each prefix is explained with examples to illustrate its use in forming new words. The tutorial concludes with a recap of the prefixes discussed.
