natural language

In neuropsychology, linguistics and the philosophy of language, a natural language or ordinary language is any language that develops naturally in humans through use and repetition (typically, in their first few years of life) without any conscious planning or premeditation of their own. Almost always, therefore, these are the languages human beings use to communicate with each other, whether by speech, signing, touch or writing. They are distinguished from constructed and formal languages such as those used to program computers or to study logic.
