Synopsis Linguistics is narrowly defined as the scientific approach to the study of language, but language can, of course, be approached from a variety of directions, and a number of other intellectual disciplines are relevant to it and influence its study. Semiotics, for example, is a related field concerned with the general study of signs and symbols both in language and outside of it. Literary theorists study the use of language in artistic literature. Linguistics additionally draws on work from such diverse fields as psychology, speech language pathology, informatics, computer science, philosophy, biology, human anatomy, neuroscience, sociology, anthropology, and acoustics. Within the field, linguist is used to describe someone who either studies the field or uses linguistics methodologies to study groups of languages or particular languages.
