The document discusses prefixes and provides examples of how prefixes can change the meaning of words. It focuses on the prefixes "un-", "dis-", "re-", "de-", and "pre-". The objectives are to understand what a prefix is, and to recognize and spell the prefixes "un" and "dis". Examples are given of words with these prefixes and how they alter the meaning of the root word, often making it an antonym. Students are asked to add prefixes to words and identify prefixes in other words. The purpose is to help students learn about prefixes and how they affect a word's definition.
