Stratification linguistics

Specifically, that there are separate 'strata' or levels in the brain used for language. Each level provides actualization or 'realization' for the next higher level, and the elements on its level are similar to each other. Several strata are involved in the production of a sound from an initial idea.

Some strata are those of

• Phoneme as the unit on the Phonemic[?] strata.
• Lexeme as a unit on the Lexical[?] strata.
• Morpheme as the unit on the Morphemic[?] strata
• Sememe[?] as the unit on the Semantic strata.
