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.
Another reason why the criterion of mutual intelligibility fails to tell us how many distinct languages there are in the world is the existence of dialect continua. To illustrate, suppose you were to start from Berlin and walk to Amsterdam, covering about ten miles every day.ne might suppose, therefore, that linguists would have a clear and reasonably precise notion of how many languages there are in the world. It turns out, however, that there is no such definite countâor at least, no such count that has any status as a scientific finding of modern linguistics.
