More Words with <cc> – and More on [ks]

1. The following words all contain assimilated forms of the prefixes ad-, sub-, or ob-. Analyze each one into prefix plus stem to show where the <cc> comes from, and fill in the blanks:

Word Analysis: Prefix + Stem The letter after <cc> is ... The <cc> spells the sound ...
accounting a\cancel{d}+ c + counting <o> [k]
accessory a\cancel{d} + c + cessory <e> [ks]
accompanied a\cancel{d} + c + companied <o> [k]
occurred o\cancel{b} + c + curred <u> [k]
occasionally o\cancel{b} + c + casionally <a> [k]
accidentally a\cancel{d} + c + cidentally <i> [ks]
accomplishment a\cancel{d} + c + complishment <o> [k]
successor su\cancel{b} + c + cessor <e> [ks]
succinctly su\cancel{b} + c + cinctly <i> [ks]
occupation o\cancel{b} + c + cupation <u> [k]

2. When there is an <\mathrm{i}> or an <e> right after <cc>, the <cc> is pronounced [ks]; otherwise <cc> is pronounced [k].

3. You've seen that sometimes <cc> spells [k] and sometimes it spells [ks]. All of the following words contain the sound [ks], spelled different ways. Underline the letters that spell the [ks] in each of these words:

& \text{e\underline{x}clusive} && \text{e\underline{x}clamation} && \text{e\underline{x}perience}\\& \text{haw\underline{ks}} && \text{comple\underline{x}ity} && \text{shar\underline{ks}} \\& \text{picni\underline{cs}} && \text{e\underline{x}plode} && \text{e\underline{x}traordinary} \\& \text{e\underline{x}tend} && \text{shrie\underline{ks}} && \text{kno\underline{cks}} \\& \text{wre\underline{cks}} && \text{economi\underline{cs}} && \text{medi\underline{cs}}

4. Sort the fifteen words into these groups:

Words in which [ks] is spelled ...
<cs> <cks> <ks> <x>
picnics knocks hawks exclusive
economics wrecks shrieks extend
medics sharks exclamation
complexity
explode
experience
extraordinary

5. Look at the words in which [ks] is spelled <cs>, <cks>, or <ks>. Each one consists of a free stem and a suffix. Analyze each word to show what the free stem and suffix are:

Word Analysis: Free Stem + Suffix
picnics picnic + s
economics economic + s
medics medic + s
knocks knock + s
wrecks wreck + s
hawks hawk + s
shrieks shriek + s
sharks shark + s

5. When [ks] is spelled <cs>, <ks>, or <cks> the <\mathrm{s}> is usually the suffix -s.

Teaching Notes.

Item 3. Re: economics. The suffix -ics is defined in the Random House Unabridged as “a suffix of nouns that denote a body of facts, knowledge, principles, etc. usually corresponding to adjectives ending in -ic”. However, they also describe -ics as the plural of -ic, which explains our analysis.

Re: the <x> words. For more on the <x> spelling of [ks] and of the voiced counterpart [gz] (in exact), see Book 6, Lesson 43, especially the teaching notes.
