Morphology

Sociolinguistics is the study of language in relation to society.

Syntax

Phonetics

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.

General linguistics, which relates itself to the research of other areas, studies the basic concepts, theories, descriptions, models and methods applicable in any linguistic study.

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

Phonetics is different from phonology in that the latter studies the combinations of the sounds to convey meaning in communication.

Both semantics and pragmatics study meanings.

Morphology studies how words can be formed to produce meaningful sentences.
