Transcript Prefixes: Un-, Non- , In-

Prefixes- un- non-, and in. "Hmmm, This is unusual." "Unusual? What do you mean by UNusual?" Let's help Dee and Kala unravel this mystery by learning about prefixes. Unusual is a word that is made up by adding a prefix to a root word. Prefixes are affixes attached to the beginning of a word to change or add to, the meaning of the root word. Un-, non-, and in- are all prefixes we put in front of a word that means NOT or WITHOUT. Adding one of these prefixes changes the meaning of the root word to the OPPOSITE. Tangle becomes untangle. Fiction becomes nonfiction. Formal become informal. We can determine the meanings of unfamiliar words by knowing how these prefixes affect the meaning of the root word. Let's look at the unusual letter Kala and Dee got from the tree to see how these prefixes affect the meaning of words. A tree full of letters is an unusual sight. Remember, the word UNUSUAL is made by adding the prefix, 'un', to the front of the word usual. Usual means something that is common or expected to happen. When un is added, it changes the meaning to the opposite... so unusual is something that is NOT common or not expected to happen. In this sentence, 'Kala and Dee found themselves in an unpredictable situation.'... what does unpredictable mean? Unpredictable means that you would not have been able to guess this event was going to happen. Another example of a prefix that means not or without, is 'non'. In this sentence, 'The message was written on a nondescript piece of white paper.' The word nondescript is made up of the root word, descript, and the prefix, non. Descript is a root that refers to something that is detailed or has interesting features. When we add the prefix, 'non' to the front of the word, it changes the meaning to something WITHOUT detail or interesting features... so, we understand that the message was on an ordinary, plain piece of paper. The writing looked like a lot of happening at an inconvenient location'... what does the word inconvenient mean about the location? It means that the party is not in a convenient, or easy to get to place. While Kala and Dee climb to the undisclosed location... Remember... prefixes are affixes attached to the nonsense. Nonsense is made from the prefix 'non' and the root 'sense'. If 'sense' means something is clear and logical, how does the prefix non change the meaning? NONsense would mean that the message is confusing and not clear. In' is another prefix for changing the meaning of the root word to mean the opposite. The directions were difficult to follow because they were in invisible ink. How does the prefix, 'in' change the meaning of visible in this sentence? Visible means you can see it so INVISIBLE means you cannot see it! In this sentence, 'The party is the beginning of a word to change or add to the meaning of the root word. Un, non, and in are all prefixes we put in front of a word that means not or without. They all change the meaning of the root word to mean the OPPOSITE. "WOW! This is INDESCRIBABLE!" "Yes, this is UNBELIEVABLE!"
