Summary.

The aim is to construct a language for the classical predicate calculus. The language is defined as a subset of the language constructed in [7]. Well-formed formulas of this language are defined and some usual connectives and quantifiers of [7], [1] are accordingly. We prove inductive and definitional schemes for formulas of our language. Substitution for individual variables in formulas of the introduced language is defined. This definition is borrowed from [6]. For such purpose some auxiliary notation and propositions are introduced.
