The video tutorial explains the concept of prefixes and suffixes in English. It details how prefixes are added to the beginning of words to change their meanings, often to the opposite. Suffixes, on the other hand, are added to the end of words to form nouns, adjectives, and adverbs. The tutorial highlights common suffixes like 'ment', 'ness', 'less', 'full', and 'ly', and notes specific spelling changes that occur when adding these suffixes, such as changing 'y' to 'i'.

What is a prefix?
