Considering linguistics as the scientific study of language entails an objective, empirical, and thorough investigation of language. In order to meet such requirements, one is expected to study the different aspects of language, written and spoken; structural and lexical. However, the learner has, first, to know what language is. Language is the most effective method of human communication. The term language is derived from the Latin word ‘lingua’ meaning ‘tongue’. Human language is in organized form. It is an open entity, new words or meanings may come into use. Language is a dynamic, creative and systemic tool for communication of information and building interpersonal relations. When language is usually defined, focus is put on human language, though it is undeniable that animals have their language, too. Therefore, a clear line between the two needs to be drawn. Human language is entirely different from animal communication. It is open‑ended and productive. It has many properties, which makes it different from animal communication. Human language has alphabets which help man to write down and preserve ideas for coming generations. Animal communication is context bound; they cannot communicate any experience of the past. Animal communication is biologically transmitted, thus, they cannot learn any other languages. Some birds like the parrot may imitate human utterances, but it reiterates the words without knowing meaning. The parrot also fails to learn more words. Thus, if it tries to learn a new utterance, the older ones get erased. Whereas, human beings can imitate the sounds of animals and make them respond to the sounds easily. Hence, human communication or human language is a unique one, which is the sole property of his.
