Modern linguistics is mostly prescriptive, but sometimes descriptive.

The discipline that studies the rules governing the formation of words into permissible sentences in languages is called s（）

D（）is one of the design features of human language which refers to the phenomenon that language consists of two levels: a lower level of meaningless individual sounds and a higher level of meaningful units.

Pragmatics

General linguistics is generally the study of language as a whole.

Linguistics is generally defined as the s（）study of language.

Modern linguistics regards the written language as primary, not the written language.

Language

Social changes can often bring about language changes.

Pragmatics is different from semantics in that pragmatics studies meaning not in isolation, but in context.
