Some contentious problems concerning the nature, functions, and phenomenology of the socalled sense of language are discussed. Conditions which necessarily require engagement by schoolchildren of the intuitive components in order to find solution of the instructional problems in the native (Russian) language have been determined. Experiments reveal that the sense of language performs the function of anticipation in the process of solving semantic-syntactic problems which require isolation of non-formal signs in a syntactic construction and also execution of some non-formal operations needed in order to transform the construction. Recommendations are given concerning introduction of corrections into the course on syntaxis for the general secondary school.
