Unlocking the Power of Negative Prefixes
Have you ever wondered how a single word can change its meaning completely with just a small addition? Imagine youāre reading a social media post or listening to a conversation, and you come across words like “happy” and “unhappy.” That tiny prefix, “un-,” turns a positive word into a negative one! In this lesson, youāll explore the world of negative prefixes. Youāll learn how they work, how they can change the meaning of words, and how to spot them in everyday language. By the end of this lesson, youāll be able to recognize and use negative prefixes confidently in your conversations, reading, and writing.

Basic Aspects of Prefixes
Negative prefixes are small but powerful additions to words that change their meaning to the opposite. Common negative prefixes include āun-ā, āin-ā, āim-ā, āil-ā, āir-ā, ādis-ā, and ānon-ā. For example, adding āun-ā to āhappyā makes āunhappy,ā which means not happy. These prefixes are useful in everyday language to express negation or the opposite of something.Ā
