Lesson 103

un-

The prefix UN- means not or opposite

Students may notice UN in words where it does not function as a prefix (e.g., uncle, run). Remember the letters UN only form a prefix when they come at the beginning of a word and change the meaning of the word to not or opposite. Reinforce understanding of prefixes by pointing out examples and non-examples in text and by using the meaning of prefixes to define new words.

Step 1

Warm Up Our Ears

Say the sounds; students blend them into a word. Then say a word; students break it apart.

Blend it (teacher says sounds → you say word)

/ŭ/ · /n/ · /l/ · /ī/ · /k/unlike
/s/ · /ā/ · /f/safe
/ŭ/ · /n/ · /s/ · /ā/ · /f/unsafe

Break it (I say word → you say sounds)

New Concept

Today we learn a new prefix, UN-, which means not or opposite.

Highlighted words are the ones to show and practice reading — tap one to hear it.

We have learned that morphemes are word parts that change the meaning of a word. Suffixes are morphemes that are added to the end of a word. Morphemes added to the beginning of a word are called prefixes. Today we will learn a new prefix: UN-. The prefix UN- is pronounced /ŭn/ like in the word . UN- means not or opposite. UN- means not in words like unhappy or unkind. Unhappy means not happy or not in a good mood. Unkind means not kind or not nice. UN- means opposite in words like unzip and uncover. Zip means close. I can zip my backpack closed. Unzip means the opposite, I can unzip my backpack open. Cover means put something over to hide or protect. I can cover my eyes with my hands if I do not want to see something. Uncover means the opposite, I can uncover my eyes so I can see.

un-

The prefix UN- means not or opposite, as in (not happy) and unzip (the opposite of zip).
