Language is creative also because of its potential to create endless sentences.

Modern linguistics is prescriptive while traditional grammar is descriptive.

Modern linguistics regards the spoken language as primary, not the written, Traditional grammarIans tended to emphasize the importance of the written word.

Modern linguistics forces language into a Latin-based framework, because modern linguists believe that Latin provides a universal framework into which all languages fit.

The distinction between competence and performance is quite similar to that between langue and parole, but they differ at least in that Saussure took a sociological view of language and Chomsky looks at language from a psychological point of view.

Chomsky thinks what linguists should study is the ideal speaker's competence, not his performance, which is too regular to be studied.

Saussure made the distinction between langue and parole because he thinks parole is a mass of linguistic facts, therefore linguists should distinguish abstract langue from parole, and parole should be the subject of study of linguistics.

Langue is the set of conventions and rules which language users all have to abide by, and parole is the concrete use of the conventions and the application of the rules.
