In the RVC, V1 describes a dynamic, developing action or state (as denoted by an inchoative verb), the action or state will eventually conclude in a consequence or result. Put in another way, the event named by V1 always involves a becoming process; in this sense, the Activity verb functions as an inchoative verb in the RVC. The becoming process denoted by V1 reaches its culmination—the resultant state named by V2. Therefore, only Activity verbs and some inchoative adjectives which are both continuous and subject to change can act as V1, while V2 must be an Achievement verb signaling a change of state. Hence the RVC has the complex structure [action + result] (Smith, 1991, Gu, 1992).
