Chomsky defines “competence” as the ideal user’s k（）of the rules of his language.

Both semantics and pragmatics study meanings.

Language is p（）in that it makes possible the construction and interpretation of new signals by its users. In other words, they can produce and understand an infinitely large number of sentences which they have never heard before.

In the study of linguistics, hypotheses formed should be based on language facts and checked against the observed facts.

Langue refers to the a（）linguistic system shared by all the members of a speech community while the parole is the concrete use of the conventions and application of the rules.

Linguistics

The distinction between competence and performance was proposed by F. de Saussure.

Modern linguistics is different from traditional grammar.

A diachronic study of language is the description of language at some point in time.

The study of meaning in language is known as semantics.
