Language is a social phenomenon and changes with the development of society. Neologisms are new words and new expressions which are the cutting edge of language. Neologisms are being invented or introduced every day to express new things and new ideas in society. Scholars usually discuss neologisms from two perspectives: the time perspective and the semantic perspective. Neologisms can be classified according to their functions, their coinage processes, their formation, and their sources. There are three main methods of new word creation: neologisms by rules of word-formation; neologisms by adding new meanings to existing words; neologisms by borrowing words from other languages. Even a single method is quite productive in new word creation.
