The Prefixes Spelled <un>

1. A part of a written word that adds meaning to the word is called an ______.

2. An element that cannot stand free as a word and that goes at the front of words is called a ______.

3. A stem that can stand free as a word is called a ______.

4. All of these words contain the same prefix:

\begin{align*} &\text{unable} &&\text{unfinished} &&\text{unclear} &&\text{uworried} &&\text{unfriendly} &&\text{untruth}\end{align*}

What is the prefix in these words? ______.

5. Divide each of these six words into its prefix and free stem:

Word = Prefix + Free Stem
unable = +
unfinished = +
unclear = +
uworried = +
unfriendly = +
untruth = +
unoriginal = +
undecided = +

6. Think about what the word unable means. Then think about what the word able means. What do you think the prefix un- must mean in unable: “not,” “again,” “yesterday,” “more than one”? ______ Does un- seem to mean this same thing in the other five words? ______.

7. Now look at these seven words:

\begin{align*}\text{unpack} &&\text{unbar} &&\text{unlock}&&\text{undo} &&\text{unwrap} &&\text{unfold} &&\text{untie}\end{align*}

What is the prefix in these words? ______ Does the prefix have the same meaning in these words that it has words like unreal? ______ What does it seem to mean in these seven words: “again,” “more than one,” “yesterday,” or “reverse?” ______

There are actually two different prefixes spelled <un>. The first un- means “not, oppositie”; the second means “reverse, remove.”

8. Divide each of these words into prefix, free stem, and suffix. Show any twinning or final <e> deletion:

Word = Prefix + Free Stem + Suffix
unannounced = un + announc\begin{align*}\cancel{e}\end{align*} + ed
undecided = + +
unlocking = + +
unlined = + +
uncolored = + +
undoing = + +
unmixed = + +
unbuttoned = + +
untouched = + +
unwrapping = + +
unbarred = + +
unfolding = + +

8. The prefixes spelled <un> mean two different things: ________________________ and ____________________________.
