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.
By this logic, when a language dies then some otherwise inarticulable concepts could die with it. In this sense the loss of a language is, then, almost as if a species is dying out â and little-spoken languages are endangered. This is why researchers and governments try and preserve ancient languages around the world, believing that some irreplaceable part of a culture is lost with each extinct language.
