Functors for the effective roots of independent clauses are functors that express the independence of the given lexical unit and determine the clause type. These functors are classified depending on whether the clause is interpreted as a verbal, nominal, interjection or vocative clause as well as whether the independent clause is analyzed as a parenthesis or not.

Verbal and nonverbal independent clauses are discussed in Section 4, "Verbal and non-verbal clauses". Parenthesis is discussed in Section 7, "Parenthesis".

The functors for the effective roots of independent clauses are assigned to the effective roots of tectogrammatical trees. Furthermore, they are assigned to all effective roots of independent clauses that occur lower in the structure of a tectogrammatical tree (for the most part, this is the case of syntactically independent parenthesis). The relations within the functors for the effective root nodes of independent clauses are presented in Table 7.2, "Relations within the functors for the effective root nodes of independent clauses".
