In the lexicon of a language, each word is represented in its underlying, or basic, form,
which discounts all of the alternations in pronunciation that are predictable by
phonological rules. For example, there are phonological rules that will account for the
variations in the placement of stress and the alternations of vowel quality that occur in
sets of words such as harmOny, harmOnic, harmOnious and melOdy, melOdic,
melOdious. The rules that predict the pronunciation of the capitalized O’s are general,
rather than specific for each word, and the grammar should state such rules so that the
regularities are revealed. Accordingly, each of these words must be entered in the
lexicon in a way that represents simply its underlying form, and that allows the
alternations that occur to be generated by phonological rules
