Whatever level we take, stylistics describes not what is in common use, but what is specific in this or that respect, what differentiates one sublanguage from others.

General (non-stylistic) phonetics investigates the whole articulatory - audial system of language. Stylistic phonetics describes variants of pronunciation occuring in different types of speech. Special attention is also paid to prosodic features of prose and poetry.

General (non-stylistic) morphology treats morphemes and grammatical meanings expressed by them in language in general, without regard to their stylistic value. Stylistic morphology is interested in grammatical forms and grammatical meanings that are peculiar to particular sublanguages, explicity or implicity comparing them with the neutral ones common to all the sublanguages.

Lexicology deals with stylistic classification (differentiation) of the vocabulary that form a part of stylistics (stylistics lexicology). In stylistic lexicology each unit is studied separately, instead of as a whole text (group of words, word classification).

General syntax treats word combinations and sentences, analyzing their structures and stating what is permissible and what is inadmissible in constructing correct utterances in the given language.

Stylistic syntax shows what particular constructions are met with in various types of speech, what syntactical structures are style forming (specific) in the sublanguages in question.

Semantic level – connected with meaning.
