The aim of this article is to make clear the fact that the semantic property of verb gives rise to double subject construction (DSC). Because DSC depends on verb classification as to whether it is formed or not. In particular, (non)agentivity which is the semantic property of verb is the primary factor as to whether DSC is formed or not. For example, nonagentive predicates form DSC, whereas agentive predicates do not form. These phenomena occur owing to the fact that nonagentive predicates do not have external argument but agentive predicates have. DSC is divided into two classes according to the valency of nonagentive verb. That is to say, the nonagentive verb which take one argument can form genitive construction, compound construction and DSC optionally, whereas the nonagentive verb which take two argument have to form DSC obligatorily. These DSCs is formed syntactically by NP-movement. For example, the argument which nonagentive predicates take, whether it is one argument or two arguments, have to move into the position that structural case can be assigned. It is because nonagentive predicates can`t assign the case to their argument. Therefore the mutiple specifier structure which is generated by NP-movement gives rise to DSC.
