Master's degree programs in linguistics are designed to provide a professional, rather than strictly academic, credential in an area with many practical applications, like computational linguistics or sociolinguistics. Some of these programs may be completed in 12 months, instead of the normal two years.The part of linguistics that is concerned with the structure of language is divided into a number of subfields:
Phonetics :-  the study of speech sounds in their physical aspects.
Phonology :-  the study of speech sounds in their cognitive aspects.
Morphology :*- the study of the formation of words.
The study concerned with the comprehension, production and abstract knowledge of language (spoken, signed or written) and human brain mechanisms.

Comments: An interdisciplinary field that encompasses linguistics, neurobiology, and computer science, among others.
