The Process of Conjunctionization of"RuoShi若是"and its Motivation
The conjunction"Ruo若"and the copula"Shi是"are used together to form the initial environment of the conjunction"RuoShi若是".As the object of"Shi是"expands from a nominal component to a verbal component,"RuoShi若是"becomes a con-junction,and"Shi是"becomes a part of the word.Among them,the zero form of the subject of the copula"Shi是"plays a crucial role.The unmarkedness of Chinese"verb-to-noun"and the innovative expression of"Shi是+verbal topic"are the main motivations for the generation of"RuoShi若是".
