Language deprivation. Language deprivation is associated with the lack of linguistic stimuli that are necessary for the language acquisition processes in an individual, usually in a very impoverished environment. Experiments involving language deprivation are very scarce due to the ethical controversy associated with it.
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.
