One set of functors that do not comply with the general definition of a functor (a functor as a semantic value of the syntactic relation of dependency) are functors for multi-word lexical units and foreign-language expressions (among others).

Functors for multi-word lexical units and foreign-language expressions are functors that are used for representing certain multi-word lexical units or foreign-language parts of Czech sentences, which are not structurally analyzed. It holds for the functors in this group, that the node assigned one of them represents either a foreign-language expression (see Section 9, "Foreign-language expressions" for more), or a dependent part of a multi-word predicate (represented (so far) by two nodes in the tectogrammatical tree; see Section 9, "Multi-word predicates"). The edge connecting the node with this functor and its parent is not expressing a dependency relation (see Section 1, "Dependency").
