What shapes language? In the past period, significant progress has been made in interdisciplinary research on this issue. Language as shaped by the brain demonstrates the proposition in the article "Language as shaped by the brain, not the other way around". While in this paper, we first review some of the ideas and results presented by Christiansen and Chater, focusing on the specific role of the brain in shaping language. Then, comprehensive reading literature considers the new and potential directions in which language is shaped, such as social interaction, cultural environment, Internet and media. Thus, it puts forward an argument and evidence both for and against this point of view, providing a historical perspective and multiple ways to the development of language and its shaping factors in a broad sense.
