The history of linguistics
捉襟见肘造句1：The structural linguistics Saussure
2：Mentalistic linguistics Noam Chomsky
3：Functional linguistics M.A.K Halliday
1：According to Saussure’s idea: Language is a system. Language is a form
Influenced by his ideas there appeared different structural linguists such as the “ Prague School” , the “ Copenhagen School”
The most influential structural linguist was the American linguist L. Bloomfield
He believed that the task for linguist is to describe all the language materials obrvable objectively and systematically. Language forms or structures should be the focus while the meaning is neglected.
2：Chomsky rejected the structural approach to language description.
Language is a system that relates meaning to substance.
Language is a mental phenomenon.
Language is innate and human-specific.
