Created by: CK-12

## Review Of <kn> And <gn>

1. Here are the words from the previous lesson in which [n] is spelled <kn>.

$& \text{knows} && \text{foreknowledge} && \text{knave} && \text{knee} && \text{knell} \\& \text{knelt} && \text{unknown} && \text{kneel} && \text{knead} && \text{knoll} \\& \text{known} && \text{knower} && \text{knight} && \text{knit} && \text{knot} \\& \text{knowable} && \text{knowledge} && \text{knife} && \text{knock}$

The <kn> is always in the same place in the element it is in. Is <kn> always at the beginning, in the middle, or at the end of its element? At the beginning

2. The word acknowledge also has [n] spelled <kn>. Acknowledge contains a prefix,a base, and a suffix: ac + know + ledge. Is the <kn> in acknowledge in the same place in its element that the <kn> is in in the nineteen words above? Yes

3. Here are some words in which [n] is spelled <gn>. Look carefully at where the <gn> is in its element in each of them:

$& \text{design} && \text{campaign} && \text{reign} \\& \text{sign} && \text{gnash} && \text{reign} \\& \text{foreign} && \text{gnat} && \text{gnu}$

You should find that the <gn> spelling of [n] always occurs in one of two places in the element it is in. What are the two places? At the beginning or at the end

Word Flow. In this Word Flow you can make more than fifty words that contain [n] spelled <n>, <nn>, <gn>, or <kn>. See how many you can make. When you are done, you should be able to find the fifteen words you need to fill in the blanks in the three groups listed below the Find.

Words with [n] spelled
<kn> <gn> <nn>

Teaching Notes.

Item 2. If a student should ask whether the ac- in acknowedge is an assimilated form of ad-, the answer is no: The ac- comes from the Old English prefix on-, which people eventually changed to make it look more like an assimilated form of ad-. (Ad- is from Latin, not Old English.) Any student who asks such a question deserves a prize for having a very good eye and posing a very intelligent question.

If the question should come up, even though there is a [k] sound in acknowledge, we still say that [n] = <kn> because the <c> is there in the prefix to spell the [k]. We say that [k] = <c> and [n] = <kn> because the <c> and <k> are in different elements, and it seems better to analyze things so that we honor the integrity of the elements.
