Decidability. Definition: A language is called decidable if there exists a method-any method at all-to determine whether a given word belongs to that language or not. Working hypothesis I: Decidability is well defined above.roof: Surely, a decidable language is recognizable. Moreover, if a language is decidable, then so is its complement, and hence that complement is recognizable. Now suppose a language L and its complement are recognizable. Let A be a recognizer for L, and B for its complement.
Halliday describes language as a semiotic system, not in the sense of a system of signs, but a systemic resource for meaning.For Halliday, language is a meaning potential; by extension, he defines linguistics as the study of how people exchange meanings by 'languaging'.alliday rejects a view of structure as strings of classes, such as nominal group + verbalgroup + nominal group, among which there is just a kind of mechanical solidarity describing it instead as configurations of functions, where the solidarity is organic.
