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.
Linguists, however, do make a distinction between the two based on the concept of mutual intelligibility. Two languages where speakers can understand each other are considered dialects of the same language, whereas two languages where the speakers cannot understand each other are, indeed, separate languages.This often isn't black and white, since understand can be a hard criterion to pin down. language is a dialect with an army and navy. His point being that the difference between a language and a dialect was ultimately a political distinction and had little to do with linguistics per se.
