Key words and phrases: the English language variants; dialectology; cognitive
Abstract: Conceptual nature of phonological units resides in the schematic principle of their organization. Syllable schemas, which determine syllable structures in a linguistic system of a dialect, show various degrees of salience and entrenchment. Syllable schemas in English dialects have different degree of entrenchment in terms of filled-onset requirement, the ‘r’-insertion schema being the most variable. The article argues the ‘r’-insertion schema emerged from the shared-consonant schema. Once a separate schema, it governs new phonological contexts in ‘r’-less dialects of English.

methodology; micro-field; popular Orthodoxy; semantic field; denotation status; formal
structural description; Christian lexis.
Abstract: The paper presents the analysis of lexis on the basis of the theory of lexico-semantic micro-fields. The study focuses on a wide collection of Christian lexis in the Russian language representing popular Orthodoxy in literary Russian and its dialects. The reflection of religious continuum of the Russian language with its motives, situations and events has always been of interest with the general public but hasn’t been studied linguistically. Russian philology has traditionally been oriented to old and archaic forms of the Old Slavonic language bun not colloquial lexis of popular Orthodoxy. This material presentation itself is a big problem which is difficult to solve. The need for studying semantic fields of Christian lexis within the selected ethno-linguistic approach is well-grounded.
