The study of meaning in language is known as semantics.

Modern linguistics is mostly prescriptive, but sometimes descriptive.

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.

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

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

Linguistics

Phonetics

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.

A scientific study of language is based on what the linguist thinks.

Both semantics and pragmatics study meanings.
