Linguistics as a discipline: Language is considered a crucial human phenomenon. Linguistics, the scientific study of language and its elements, contributes to our knowledge of human society by investigating the nature of human communication. There exists a rich history of studying linguistics in many parts of the world, especially ancient India, Greece and China. The importance of this discipline is now recognized throughout the world. As a branch of modern human science, linguistics deals with language, its components, and language-related domains, ranging from natural language processing and artificial intelligence of information and communication technology to neurolinguistic aspects and language pathology. Linguistics makes use of subjects such as philosophy, sociology, anthropology, literary criticism, semiotics, biology, mathematics and statistics. ‘Linguistics’, thus ‘is an essentially outward-looking discipline combining well with other degree subjects and courses.’
