• nouns as substance names,

• Verbs as process names,

• adjectives as primary property names,

• adverbs as secondary property names.

The whole notional set is represented by the four-stage derivational paradigm of nomination.

The second part of the lexicon forming a closed set includes substitutes of names (pro-names). Here belong pronouns, broad-meaning notional words which constitute various marginal subsets (e.g. I wish at her age she’d learn to sit quiet and not do things. Flora’s suggestion is making sense.)

The third part of the lexicon also forming a closed set includes specifiers of names. These are function-categorical words of various serving status.

Substitutes of names and specifiers of names stand with the names in nominative correlation as elements of the lexicon. At the same time they serve as connecting links between the names within the lexicon and their actual uses in the sentence of living speech.
