Linguistics is often called «the science of language», the study of the human capacity to communicate and organize thought using different tools (the vocal tract for spoken languages, hands for sign languages) and involving different abstract and tactile components. When you see something interesting or shocking, when you try to remember a fact or setting, express anger or love, you do this through the medium of language. When you read, sing, study, write, chat or daydream, language is at the heart of your experience. The study of linguistics is not just an investigation into words or sounds, but into the heart of humanity.
