natural + language


natural language (countable and uncountable, plural natural languages)

  1. (retronym, linguistics) Any human language that has evolved naturally in a community, usually in contrast to computer programming languages, to controlled natural languages, and to constructed languages such as Esperanto (although constructed languages are subject to change by natural forces among fluent speakers).
    Although some computer programs are now widely regarded as having passed the Turing test, it is clear to discerning humans that they still do not use natural language in the same way that sane humans do, as they often spew nonsense, albeit well-formed linguistically, and they cannot engage in some important kinds of original thought.
