Syntax is different from morphology in that the former not only studies the morphemes, but also the combination of morphemes into words and words into sentences.

Both semantics and pragmatics study meanings.

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

Syntax

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

Phonology

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.

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

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

The study of the ways in which morphemes can be combined to form words is called morphology.
