Language is Productive and Creative: Language has creativity and productivity. The structural elements of human language can be combined to produce new utterances, which neither the speaker nor his hearers may ever have made or heard before any, listener, yet which both sides understand without difficulty. Language changes according to the needs of society.
Finally, language has other characteristics such as Duality referring to the two systems of sound and meaning, Displacement which means the ability to talk across time and space, Humanness which means that animals cannot acquire it, Universality which refers to the equilibrium across humanity on linguistic grounds, Competence and Performance which means that language is innate and produced is society and furthermore, language is culturally transmitted. It is learnt by an individual from his elders, and is transmitted from one generation to another. Thus using J. Firth’s term, language is a ‘polysystametic’. It is also open to be studied from multifaceted angles.
