Sakura Suki, Contrived language is the language published in many ESL textbooks. It is created to pass on to the student the knowledge of formal English sentence structures and grammar. It gives the student the ability to pass language exams, but not the ability to effectively communicate with native speakers. Why?...because it is often not related to the way that everyday English speakers actually talk and write. Living language is authentic spoken and written English. There is where you will learn the everyday sentence structures and words that people use when they communicate with each other. Anyone who has found a language partner on Skype or who regularly communicates by email with native English speakers knows the difference between textbook (contrived) English and the living English language.

Live language means the authors talking about something real, live, active. While contrived language is made-up of imagination. (artificial )
