This paper suggests and substantiates the hypothesis that there is a speech phenomenon not manifesting itself semantically and not presented in symbols. This phenomenon is operational structures, attached to meanings. Operational structures are composed of elements establishing quantitative and elective (carrying directed substitution) relations. Nonsemantic by themselves, operational structures can be revealed by means of a representation called semantic reading. The operational structures describe sentence construction on a level deeper than surface grammar but less detailed than semantics. The objective of this paper is to show how grammatical construction of speech is formed on this level.
