5. When [ks] is spelled <cs>, <ks>, or <cks> the <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.
