Its most important component exists in language, spoken and written, which is fundamental to everyday human interaction.
Language is the vehicle that transmits information, emotion, and ideas between people.
It is a phenomenon that can relay useless facts or important detail, raw emotion or complex sentiment. Not only does language allow one to express his individuality of thought and provide an outlet for emotion, it is also the tool that builds relations between individuals and keeps them intact.

Linguistics is the study of language and all of its components and aspects. It is a scientific field which exists for the better understanding of human communication.
