Language

Language is a structured system of communication used by humans, including speech (spoken language), gestures (sign language) and writing. The most widely-spoken languages have writing systems of glyphs that enable sounds or gestures to be inscribed for later reactivation.

The scientific study of language is called linguistics. Examinations of languages, such as the philosophy of language, the relationship between language and thought etc. such as how words represent experience has been debated at least since elden Greek times. Thinkers and linguists have debated that language originated from emotions, while others have held that language originated from rational and logical thought. Twentieth century philosophy argued that philosophy is really the study of language itself. Estimates of the number of human languages in the world vary from 5000 to 7000. However, any precise estimate depends on the distinction between languages and dialects. Languages are spoken or signed, but any language can be encoded into secondary media using auditory, visual, or tactile stimuli - for example in writing, whistling, signing, or braille. In short, human language is modality-independent, but written or signed language is the way to inscribe natural human speech or gestures. when used as a general concept, "language" may refer to the cognitive ability to learn and use systems of complex communication, or to describe the set of rules that makes up these systems, or the set of utterances that can be produced from those rules.
