# 7.11: Lesson Eleven

Created by: CK-12

1. Many of our words come from Latin, the language spoken by the ancient Romans. Many of these old Latin words contain a prefix that was at first spelled <ad> and meant “to, toward.”

In some words the [d] in the prefix ad- has changed to a different sound, and the <d> has been replaced by a different letter.

We can divide adventure into its prefix and stem like this: ad + venture.

And we could divide appoint into its prefix and stem like this: ap + point. But the <ap> in appoint is really a changed form of the prefix ad-. The <d> has been replaced with a $<\text{p}>$: a$\cancel{d}$ + p + point.

The <d> in ad- is deleted, and a $<\text{p}>$ is put in its place.

In adventure, we add the prefix and the stem together by simple addition. But in the word appoint we replace the <d> in the prefix with a $<\text{p}>$.

2. Each of the following words begins with some form of the prefix ad-. Sometimes the <d> has stayed <d>. Sometimes it has been replaced by another letter. Analyze each word into its prefix and its stem the way we did with adventure and appoint. If the <d> has been replaced with a different letter, show that change in your analysis.

Words = Prefix + Stem
appoint = a$\cancel{d}$ + p + point
approve = +
apply = +
acclaim = +
account = +
attack = +
allow = +
assist = +
attend = +

3. Now sort the words in the Words column into these two groups:

Word Venn. In circle A put only words that contain some form of the prefix ad-. In circle B put only words that contain the prefix re-. In circle C put only words that contain the prefix un-.

$&\text{appoint} && \text{readjust} && \text{unapproved}\\&\text{unreceptive} && \text{unreassuring} && \text{unclaimed}\\&\text{unjust} && \text{unassisted} && \text{unregretted}\\&\text{realize} && \text{reclaimed} && \text{universe}\\&\text{acclaimed} && \text{readmitted} && \text{receiving}$
