s are often studied in terms of seven major subsystems, which relate to major subfields within linguistics. In addition, particular subfields of linguistic inquiry may divide their subject matter into more specific subsystems. This list contains links to commonly studied language subsystems.

Major subsystems

Linguists recognize seven major language subsystems: *

Phonetics Phonetics is a branch of linguistics that studies how humans produce and perceive sounds or, in the case of sign languages, the equivalent aspects of sign. Linguists who specialize in studying the physical properties of speech are phoneticians ...

speech Speech is the use of the human voice as a medium for language. Spoken language combines vowel and consonant sounds to form units of meaning like words, which belong to a language's lexicon. There are many different intentional speech acts, suc ...
